Résumé

Non-infectious chronic diseases in human including diabetes, non-alcoholic fatty liver disease (NAFLD), atherosclerosis (AS), neurodegenerative diseases, osteoporosis, as well as malignant tumors may have some common pathogenic mechanisms such as non-resolved inflammation (NRI), gut microbiota dysfunction, endoplasmic reticulum stress, mitochondria dysfunction, and abnormality of the mammalian target of rapamycin (mTOR) pathway. These pathogenic mechanisms could be the basis for "homotherapy for heteropathy" in clinic. Some commonly used clinical drugs, such as metformin, berberine, aspirin, statins, and rapamycin may execute therapeutic effect on their targeted diseases,and also have the effect of "homotherapy for heteropathy". The mechanisms of the above drugs may include anti-inflammation, modulation of gut microbiota, suppression of endoplasmic reticulum stress, improvement of mitochondria function, and inhibition of mTOR. For virus infectious diseases, as some viruses need certain commonly used replicases, the inhibitors of the replicases become examples of "homotherapy for heteropathy" for antiviral therapy in clinic (for example tenofovir for both AIDS and HBV infection). Especially, in case of outbreak of new emerging viruses, these viral enzyme inhibitors such as azvudine and sofibuvir, could be rapidly used in controlling viral epidemic or pandemic, based on the principle of "homotherapy for heteropathy". In this review article, we show the research progress of the biological basis for "homotherapy for heteropathy" and the possible mechanisms of some well-known drugs, in order to provide insights and new references for innovative drug R&D.

Résumé

AIM: To explore the intervention effect of Dahuangtang pellets (DHT) on diabetic nephropathy (DN) based on the AMP-activated protein kinase/mammalian target of rapamycin/unc-51-like kinase 1 (AMPK/mTOR/ULK1) signaling pathway. METHODS: Eight mice were randomly assigned to the model group, the dapagliflozin group, and the DHT (high, medium, and low dosage) group out of a total of 40 C57BL/KSJ-db/db (hereafter referred to as db/db) mice; another 10 C57BL/KSJ-db/dm mice were used as the normal group, saline was provided to the normal and model groups, and the mice in the treatment group received the appropriate medications. The medications were given for 10 consecutive weeks, once per day, to the mice in the treatment group. At weeks 0, 4, 8, and 10 of administration, fasting blood glucose (FBG) was assessed by drawing blood at a predetermined time from the tail vein; Urine samples were taken at 0, 5, and 10 weeks after treatment to evaluate the levels of albumin and creatinine, and the urinary albumin-creatinine ratio (ACR) was computed. After 10 weeks, mice in each group were assayed for 24 h total urine protein, serum creatinine (Scr), urea nitrogen (BUN) levels; Western blotting analysis was conducted to detect the expression of p-AMPK, p-mTOR, and p-ULK1, as well as the expression of autophagy related proteins homolog of yeast Atg6 (Beclin-1), autophagy-related proteins microtubule-associated protein 1 light chain 3 (LC3), P62 in renal tissue; Immunohistochemistry was used to measure the expression of podocyte lacunar membrane proteins (Nephrin, Podocin) in renal tissues; The pathological morphology of renal tissue was observed by light microscopy and transmission electron microscopy. RESULTS: Compared with the model group, FBG, ACR, and 24 h total urine protein were reduced in the dapagliflozin group and DHT groups of mice, and there was no statistically significant difference in Scr and BUN; In renal tissues, there is increased expression of p-AMPK and p-ULK1, decreased expression of p-mTOR, increased expression of LC3II / LC3I and Beclin-1, and decreased expression of P62 (P<0.01, P< 0.05); differentially upregulated in glomeruli are the podocyte lacunar membrane proteins Nephrin and Podocin (P<0.01, P<0.05); renal pathologic damage was reduced to varying degrees; transmission electron microscopy showed an increase in the number of autophagic vesicles and autophagic lysosomes. CONCLUSION: DHT can delay the development of DN by regulating the AMPK / mTOR / ULK1 signaling pathway, enhancing podocyte autophagy, and protecting glomeruli.

Résumé

ObjectiveExploring the role of microRNA126 (miRNA126) in chronic kidney disease combined with atherosclerosis (CKD AS) by regulating the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway and the mechanism of Shenshuai Xiezhuo decoction in the intervention of CKD AS rats with 5/6 nephrectomy combined with high-fat feeding. MethodA total of 60 SD rats were randomly divided into sham operation group, model group, losartan group, and low, medium, and high dose groups of Shenshuai Xiezhuo decoction. The CKD AS rat model was established by 5/6 nephrectomy combined with high-fat feeding for 10 weeks. The low, medium, and high dose groups (6.0, 12.0, 24.0 g·kg-1·d-1) of Shenshuai Xiezhuo decoction and the losartan group (20 mg·kg-1·d-1) were gavaged, and the corresponding intervention was carried out for eight weeks. Then, the rats were killed, and samples were collected for corresponding detection. Fully automated biochemical analyzers were used to detect kidney function and blood lipids in rats: blood creatinine (SCr), blood urea nitrogen (BUN), total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) levels. Hematoxylin-eosin (HE) and Masson staining of aortic tissue and pathological observation under a light microscope were carried out, and autophagosomes and autophagy lysosomes were observed by transmission electron microscopy. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to determine the mRNA levels of miRNA126, PI3K, Akt, and mTOR in rats, and Western blot was used to determine the protein expression levels of phosphorylated (p)-PI3K, PI3K, p-Akt, Akt, p -mTOR, mTOR, benzyl chloride 1 (Beclin-1), and microtubule-associated protein light chain 3Ⅱ/Ⅰ (LC3Ⅱ/LC3Ⅰ). ResultCompared with the sham operation group, the serum SCr, BUN, TC, TG, and LDL-C in the model group were significantly increased (P<0.01). Compared with the model group, the SCr, BUN, TC, TG, and LDL-C were decreased in the losartan group and low, medium, and high dose groups of Shenshuai Xiezhuo decoction (P<0.05). Compared with the sham operation group, thickening plaques, infiltration of mononuclear macrophages, a small number of foam cells, disordered arrangement of smooth muscle fibers in the tunica media, and increased collagen fibers were observed in the model group, and the lesions in the losartan group and Shenshuai Xiezhuo decoction groups were alleviated compared with those in the model group. Compared with the model group, the number of autophagosomes and autophagy lysosomes increased in the medium and high dose groups of Shenshuai Xiezhuo decoction. Compared with the sham operation group, the expression of miRNA126 in the aortic tissue of the model group was significantly decreased (P<0.01), and the mRNA expressions of PI3K, Akt, and mTOR were significantly increased (P<0.01). Compared with the model group, the expression of miRNA126 in the aortic tissue of rats in high, medium, and low dose groups of Shenshuai Xiezhuo decoction and losartan group was significantly increased (P<0.01), while the mRNA expressions of PI3K, Akt, and mTOR were significantly decreased (P<0.01). Compared with the sham operation group, the protein expressions of p-PI3K, PI3K, p-Akt, Akt, p-mTOR, and mTOR in the model group were significantly increased (P<0.01), while the protein levels of Beclin-1, LC3Ⅰ, and LC3Ⅱ were significantly decreased (P<0.01). Compared with the model group, the protein expressions of p-PI3K, PI3K, p-Akt, Akt, p-mTOR, and mTOR in the losartan group and low, medium, and high dose groups of Shenshuai Xiezhuo decoction were decreased (P<0.05), while the protein levels of Beclin-1 and LC3Ⅱ/LC3Ⅰ were increased (P<0.05). ConclusionThe expression of miRNA126 is decreased in the aortic tissue of CKD AS rats, and the PI3K/Akt/mTOR pathway is activated to inhibit autophagy flux. Shenshuai Xiezhuo decoction regulates the PI3K/Akt/mTOR signaling pathway through miRNA126, restores the autophagy of aortic endothelial cells, protects the damage of CKD vessels, reduces the formation of As plaques, and slows the development of cardiovascular complications.

Résumé

ObjectiveTo investigate the clinical efficacy of Qihuang Jianpi Zishen Granules in the treatment of systemic lupus erythematosus (SLE) and its effect on the signal transducer and activator of tranSCription 3/mammalian target of rapamycin (STAT3/mTOR) signaling pathway, and to decipher the possible mechanism. MethodSixty female SLE patients who met the criteria in the First Affiliated Hospital of Anhui University of Chinese Medicine from May 2022 to May 2023 were selected and randomized into a control group and an observation group (30 cases in each group). The control group was treated with prednisone acetate + hydroxychloroquine sulfate orally, and the observation group was additionally treated with Qihuang Jianpi Zishen granules. The treatment lasted for 8 weeks. The SLE disease activity (SLEDAI), TCM syndrome score, erythrocyte sedimentation rate (ESR), hypersensitive C-reactive protein (hs-CRP), immune indexes [immunoglobulin G (IgG), C3, C4, CD4+, and CD8+], interleukin (IL)-17, IL-23, interferon (IFN)-γ, 24 h urinary protein (24 h PRO), serum creatinine (SCr), and expression of proteins [STAT3, phosphorylated (p)-STAT3, mTOR protein and STAT3,mTOR mRNA] in the STAT3/mTOR signaling pathway were determined before and after treatment. In addition, the adverse reactions were recorded. ResultAfter 8 weeks of treatment, the total response rate in the observation group was 93.33% (28/30), which was higher than that (70.00%, 21/30) in the control group (χ2=4.007, P<0.05). After treatment, both groups showed declined SLEDAI, TCM syndrome score, ESR, hs-CRP, IgG, CD8+, IL-17, IL-23, IFN-γ, 24 h PRO, SCr, and expression of proteins in the STAT3/mTOR pathway (P<0.01) and elevated levels of C3, C4, and CD4+ (P<0.01). Moreover, the observation group had lower SLEDAI, TCM syndrome score, ESR, hs-CRP, IgG, CD8+, IL-17, IL-23, IFN-γ, 24 h PRO, SCr, and expression of proteins in the STAT3/mTOR pathway (P<0.05, P<0.01) and higher levels of C3, C4, and CD4+ (P<0.05, P<0.01) than the control group after treatment. Neither group showed serious adverse reactions during the treatment period. ConclusionQihuang Jianpi Zishen Granules can ameliorate the inflammatory response, reduce the disease activity, and mitigate the kidney injury in SLE by inhibiting the STAT3/mTOR signaling pathway to regulate the immune function.

Résumé

ObjectiveTo explore the mechanism of Wenyang Jieyu prescription in regulating hippocampal neuron apoptosis and improving synaptic plasticity in the mouse model of depression induced by maternal separation combined with restraint stress. MethodThe mice on postnatal day 0 (PD0) were randomly assigned into a control group (n=10) and a modeling group (n=50). Maternal separation combined with restraint stress was adopted to establish the mouse model of depression, and the modeled mice were randomized into model, Wenyang prescription, Jieyu prescription, Wenyang Jieyu prescription, and fluoxetine groups (n=10) on the weaning day (PD21). From PD21 to PD111, the mice were fed with the diets mixed with corresponding medicines. The sucrose preference test, open field test, O-maze test, and novel object recognition test were then conducted to evaluate the depression, memory, and learning abilities of mice. Immunohistochemistry (IHC) was employed to measure the atomic absorbance (AA) of postsynaptic density protein 95 (PSD95) in the hippocampus. Terminal-deoxynucleoitidyl transferase-mediated nick-end labeling (TUNEL) was employed to detect the apoptosis of hippocampal neurons. Western blot was employed to determine the protein levels of brain-derived neurotrophic factor (BDNF), phosphorylated tyrosine kinase receptor B/tyrosine kinase receptor B (p-TrkB/TrkB), phosphorylated protein kinase B/protein kinase B (p-Akt/Akt), phosphorylated mammalian target of rapamycin/mammalian target of rapamycin (p-mTOR/mTOR), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X (Bax), cysteinyl aspartate-specific proteinase-3 (Caspase-3), synaptophysin (Syn), and PSD95. ResultCompared with the control group, the modeling decreased the sucrose preference rate, time spent in central zone within 5 min, total movement distance, time spent in the open arm, and cognition index (P<0.01). Furthermore, it decreased the expression of PSD95, increased the neuron apoptosis in the hippocampus (P<0.01), down-regulated the protein levels of BDNF, p-TrkB/TrkB, p-Akt/Akt, p-mTOR/mTOR, Bcl-2, PSD95, and Syn (P<0.01), and up-regulated the protein levels of Bax and Caspase-3 (P<0.05) in the hippocampus. Compared with the model group, Wenyang Jieyu prescription and fluoxetine increased the sucrose preference rate, time spent in central zone within 5 min, total movement distance, time spent in the open arm, and cognition index (P<0.05, P<0.01). Moreover, the drugs increased the expression of PSD95, reduced the neuron apoptosis (P<0.01), up-regulated the protein levels of BDNF, p-TrkB/TrkB, p-Akt/Akt, p-mTOR/mTOR, Bcl-2, PSD95, and Syn (P<0.01), and down-regulated the protein levels of Bax and Caspase-3 (P<0.01). ConclusionWenyang Jieyu prescription outperformed Wenyang prescription and Jieyu prescription in the treatment of the depressive behavior induced by maternal separation combined with restraint stress in mice. It exerted the therapeutic effect by reducing the hippocampal neuron apoptosis and improving the synaptic plasticity via the BDNF/Akt/mTOR pathway.

Résumé

Solid organ transplantation has significantly prolonged the survival of patients with end-stage diseases. However, long-term use of immunosuppressants will increase the risk of post-transplantation diabetes mellitus (PTDM) in the recipients, thereby elevating the risk of infection, cardiovascular disease and death. In recent years, with persistent improvement of diagnostic criteria of PTDM, clinicians have deepened the understanding of this disease. Compared with type 2 diabetes mellitus, PTDM significantly differs in pathophysiological characteristics and clinical progression. Hence, different treatment strategies should be adopted. Early identification of risk factors of organ transplant recipients, early diagnosis and intervention are of significance for improving the quality of life of recipients, prolonging the survival of grafts and reducing the fatality of recipients. Therefore, the diagnosis, incidence and risk factors of PTDM were reviewed in this article, aiming to provide reference for clinicians to deliver prompt diagnosis and intervention for PTDM.

Résumé

ObjectiveTo explore the protective mechanism of paeoniflorin on mice with ulcerative colitis (UC) through the adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) autophagy pathway. MethodUC mouse model was established by allowing mice freely drink 4% DSS, and 56 BALB/c male mice were randomly divided into model group, AMPK inhibitor group (20 mg·kg-1), paeoniflorin (50 mg·kg-1) + inhibitor (20 mg·kg-1) group, and high dose (50 mg·kg-1), medium dose (25 mg·kg-1), and low dose (12.5 mg·kg-1) paeoniflorin groups. After seven days of drug intervention, the protective effect of paeoniflorin on mice with UC was determined by comparing the body weight, disease activity index (DAI) changes, and Hematoxylin-eosin (HE) staining results. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in the serum of mice in each group, and immunofluorescence was utilized to detect microtubule-associated protein 1 light chain 3 (LC3) content in the colon, AMPK, mTOR proteins, and their phosphorylated proteins including p-AMPK and p-mTOR in the colon tissue were detected by Western blot, and the mRNA expression levels of AMPK, mTOR, Beclin1, LC3, and p62 were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultCompared with the blank group, the model group showed a decrease in body mass, an increase in DAI score, and severe pathological damage to the colon. The levels of inflammatory factors including TNF-α and IL-6 increased in serum (P<0.01), while the protein levels of LC3 and p-AMPK/AMPK were down-regulated in colon tissue, and those of p-mTOR/mTOR were up-regulated (P<0.01). The mRNA expression levels of AMPK and LC3 were down-regulated, while the mRNA expression levels of mTOR and p62 were up-regulated (P<0.01). Compared with the model group and the paeoniflorin + inhibitor group, the mice treated with paeoniflorin showed an increase in body mass, a decrease in DAI score, a reduction in pathological damage to colon tissue, and a reduction in the levels of inflammatory factors of TNF-α and IL-6 in serum (P<0.05). The protein levels of LC3 and p-AMPK/AMPK in colon tissue were up-regulated, while the protein levels of p-mTOR/mTOR were down-regulated (P<0.01). The mRNA expression levels of AMPK, Beclin1, and LC3 were up-regulated, while the mRNA expression of mTOR and p62 were down-regulated (P<0.01). The colon tissue of the inhibitor group was severely damaged, and the trend of various indicators was completely opposite to that of the high dose paeoniflorin group. ConclusionPaeoniflorin can enhance autophagy and reduce inflammatory damage in mice with UC by activating the AMPK/mTOR signaling pathway and thus play a protective role.

Résumé

ObjectiveTo observe the effects of Hirudo, Notoginseng Radix et Rhizoma, and drug pair on renal pathological morphology and protein phosphatase 2A (PP2A)/adenylate activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signal pathway in rats with chronic renal failure (CRF). MethodThe 55 male SD rats were randomly divided into a normal group (n=11) and a modeling group (n=44). The normal group was fed conventionally, and the modeling group was given 0.25 g·kg-1·d-1 adenine by gavage for 28 days to replicate the CRF model. After successful modeling, rats were randomly divided into model group, Hirudo group (3 g·kg-1·d-1), Notoginseng Radix et Rhizoma group (3 g·kg-1·d-1), and Hirudo + Notoginseng Radix et Rhizoma group (3 g·kg-1·d-1), with 9 rats in each group. The normal group and model group were given a constant volume of normal saline by intragastric administration for 30 days. At the end of the experiment, the levels of serum creatinine (SCr) and urea nitrogen (BUN) in all groups were measured. The renal pathological morphology changes were observed by hematoxylin-eosin (HE) staining, Masson staining, and electron microscopy. The mRNA expressions of PP2A, AMPK, and mTOR were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of PP2A, AMPK, phosphorylation(p)-AMPK, mTOR, and p-mTOR in renal tissue were detected by Western blot. ResultCompared with the normal group, the renal pathological structure changes were obvious, and the levels of SCr and BUN were significantly increased. The mRNA expression of PP2A, protein expression of PP2A, and p-mTOR/mTOR expression were significantly increased, and the p-AMPK/AMPK was significantly decreased in the model group (P<0.05). Compared with the model group, the renal pathological morphology changes were significantly improved, and the levels of SCr and BUN were significantly decreased. The mRNA expression of PP2A, protein expression of PP2A, and p-mTOR/mTOR expression in the renal tissue were significantly decreased, and the p-AMPK/AMPK was significantly increased (P<0.05) in all groups after drug intervention. In addition, the effect in the Hirudo+Notoginseng Radix et Rhizoma group was better. The mRNA expression levels of AMPK and mTOR in the renal tissue were not significantly different among the normal group, model group, and other groups. ConclusionThe efficacy of Hirudo and Notoginseng Radix et Rhizoma pairs in improving renal fibrosis in rats with CRF is significantly better than that of the single drug, and its improvement on renal fibrosis in rats with CRF may be related to the regulation of PP2A/AMPK/mTOR signaling pathway.

Résumé

OBJECTIVE@#To explore the mechanism of electroacupuncture (EA) in promoting recovery of the facial function with the involvement of autophagy, glial cell line-derived neurotrophic factor (GDNF), and phosphatidylinositol-3-kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling pathway.@*METHODS@#Seventy-two male Sprague-Dawley rats were randomly allocated into the control, sham-operated, facial nerve injury (FNI), EA, EA+3-methyladenine (3-MA), and EA+GDNF antagonist groups using a random number table, with 12 rats in each group. An FNI rat model was established with facial nerve crushing method. EA intervention was conducted at Dicang (ST 4), Jiache (ST 6), Yifeng (SJ 17), and Hegu (LI 4) acupoints for 2 weeks. The Simone's 10-Point Scale was utilized to monitor the recovery of facial function. The histopathological evaluation of facial nerves was performed using hematoxylin-eosin (HE) staining. The levels of Beclin-1, light chain 3 (LC3), and P62 were detected by immunohistochemistry (IHC), immunofluorescence, and reverse transcription-polymerase chain reaction, respectively. Additionally, IHC was also used to detect the levels of GDNF, Rai, PI3K, and mTOR.@*RESULTS@#The facial functional scores were significantly increased in the EA group than the FNI group (P<0.05 or P<0.01). HE staining showed nerve axons and myelin sheaths, which were destroyed immediately after the injury, were recovered with EA treatment. The expressions of Beclin-1 and LC3 were significantly elevated and the expression of P62 was markedly reduced in FNI rats (P<0.01); however, EA treatment reversed these abnormal changes (P<0.01). Meanwhile, EA stimulation significantly increased the levels of GDNF, Rai, PI3K, and mTOR (P<0.01). After exogenous administration with autophagy inhibitor 3-MA or GDNF antagonist, the repair effect of EA on facial function was attenuated (P<0.05 or P<0.01).@*CONCLUSIONS@#EA could promote the recovery of facial function and repair the facial nerve damages in a rat model of FNI. EA may exert this neuroreparative effect through mediating the release of GDNF, activating the PI3K/mTOR signaling pathway, and further regulating the autophagy of facial nerves.

Résumé

ObjectiveTo observe the effect of Zhuluan decoction on the ovarian reserve function of rats with cyclophosphamide-induced premature ovarian insufficiency, and explore the protective mechanism of Zhuluan decoction in the rat model of premature ovarian insufficiency based on the phosphatidylinositol-3-kinases/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway. MethodSixty female SD rats were randomly divided into normal group (n=10) and model group (n=50). The model group was given intraperitoneal injection of cyclophosphamide (50 mg·kg-1 loading dose on the 1st day+8 mg·kg-1 low-dose maintenance on the 2nd–15th days). After successfully modeling, the rats were randomly divided into model group, positive drug (progynova) group (0.1 mg·kg-1·d-1), and low-, medium-, and high-dose Zhuluan decoction groups (14, 28, 56 g·kg-1·d-1 ), with 10 rats in each group. The model group and the normal group were given equal volume of distilled water by gavage, once a day, continuous administration for 21 d. The estrous cycle and body weight of rats in each group were detected, and the ovarian organ index and uterine organ index were calculated. The ovarian tissue pathology and ovarian follicle counts at all levels were determined by hematoxylin-eosin (HE) staining. The content of the serum antimullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and inhibin-B (INH-B) of rats was determined by enzyme-linked immunosorbent assay (ELISA), and the protein expression levels of PI3K, Akt, mTOR in the rat ovarian tissue were determined by Western blot. The microtubule-associated protein 1 light chain 3B (LC3B) protein expression in the rat ovarian tissue was determined by immunohistochemistry. ResultAs compared with the blank group, the estrous cycle of rats in the model group was disordered, the body weight, ovarian organ index, and uterine organ index decreased, the number of primordial follicles decreased, and the number of secondary follicles and atretic follicles increased. In the model group, FSH increased (P<0.01), LH increased (P<0.05), AMH level decreased (P<0.05), the protein expression levels of PI3K, Akt, and mTOR in the ovarian tissue decreased (P<0.01), and the protein expression level of LC3B increased significantly (P<0.01). As compared with the model group, the above indexes were improved in the progynova group and different doses of Zhuluan decoction groups, the content of AMH increased (P<0.05), and FSH decreased (P<0.05). In the progynova group and different doses of Zhuluan decoction groups, the protein expression level of LC3B decreased obviously (P<0.01), and the protein expression levels of PI3K, Akt, and mTOR all showed an increasing trend. Moreover, there was a statistically significant difference in the progynova group and low- and medium-dose Zhuluan decoction groups (P<0.05). ConclusionZhuluan decoction may inhibit the occurrence of excessive autophagy in ovarian granulosa cells by activating the PI3K/Akt/mTOR pathway, thereby reversing the effect of modeling on ovarian reserve in rats.

OBJECTIVE To investigate the improvement effect mechanism of Xibining prescription (XBN) on knee osteoarthritis (KOA) model rats based on AMP-activated protein kinase(AMPK)/mammalian target of rapamycin (mTOR) signaling pathway. METHODS Totally 36 rats were randomly divided into blank group, model group, XBN group (12.56 g/kg), XBN+metformin (AMPK agonist) group (12.56 g/kg XBN+100 mg/kg metformin), with 9 rats in each group. Except for blank group, KOA model was induced by anterior cruciate ligament transection in other groups. After modeling, each group was given relevant medicine/normal saline, XBN and normal saline intragastrically, once a day, and metformin intraperitoneally, every other day, for 4 consecutive weeks. The pathomorphological changes of cartilage tissue in rats were observed and Mankin scoring was conducted. The expression level of Aggrecan in rat cartilage, mRNA and protein expressions of platelet reactive protein disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS-4), ADAMTS-5, matrix metalloproteinase 3 (MMP-3) and MMP- 13, and the phosphorylation level of AMPK and mTOR proteins were detected. RESULTS Compared with blank group, the structure of cartilage tissue in the model group was disordered, the matrix of cartilage layer was lightly stained,the tide line was distorted or interrupted, and Mankin score was significantly increased (P<0.05). The protein expression of Aggrecan in cartilage tissue and the phosphorylation level of AMPK protein were all decreased significantly (P<0.05); mRNA and protein expressions of ADAMTS-4, ADAMTS-5, MMP-3 and MMP-13 and the phosphorylation levels of mTOR protein were significantly increased in cartilage tissues (P<0.05). Compared with model group, the pathological morphology of cartilage was improved significantly in each administration group, and above score or indexes were reversed significantly (P<0.05). Compared with XBN group, the degree of cartilage lesions in rats was further alleviated in XBN+ metformin group, and the levels of above score or indicators were further improved (P<0.05). CONCLUSIONS XBN can ameliorate cartilage injury in KOA model rats, promote cartilage synthesis and reduce cartilage degradation, the mechanism of which may be associated with activating AMPK/mTOR signaling pathway.

Objective To explore the effect of activation of mammalian target of rapmycin complex 2(mTORC2)/Akt signaling pathway on dopaminergic neurons and behavior in 6-hydroxydopamine (6-OHDA) model mice and its possible mechanism. Methods Selecting 36 mice which The Nestin-CreERTM and ROSA26-LacZ reporter genes were detected at the same time in 3-month-old male C57BL/6J mice weighing 20-25 g divideng them into 4 gruops, NS+ corn oil group, 6-OHDA+corn oil group, 6-OHDA+PP242 group and 6-OHDA+A-443654 group, and 6-OHDA was injected into the right striatum of the brain to replicate the Parkinson’s disease (PD) model of mice, and then daily intraperitoneal injection of mTORC2/Akt signaling pathway agonist A-443654 or inhibitor PP242. Serum interleukin-1β (IL-1β) and tumor necrosis factor-α(TNF-α)levels were measured by enzyme-linked immunosorbent assay. Immunohistochemistry and immunofluorescence staining were performed to investigate the change of microglia, dopaminergic neurons as well as neural progenitor cells (NPCs). Western blotting was used to detect the expression of related protein of mTORC2/Akt signaling pathway including rictor, p-Akt and regulated in development and DNA dgmage responses 1(REDD1) and the interaction between them were verified by immunoprecipitation. Finally, the behavioral performance of each group of mice was observed. Results With the activation of microglia and the increase of inflammatory factors in PD model mice, the number of dopaminergic neurons in the substantia nigra(SN) decreased significantly, and the motor function of the mice was impaired, but the number of NPCs increased significantly compared with the control mice, mTORC2/Akt signaling pathway related protein expression was also significantly up-regulated. A-443654 treatment further up-regulated the expression of these proteins, meanwhile the indicators mentioned above were ameliorated. However, the inhibitor PP242 treatment group showed completely opposite result with the agonist group. Conclusion A-443654 can promote the proliferation of NPCs and the number of new-born dopaminergic neurons by up-regulating related proteins of mTORC2/Akt signaling pathway, and reducing the activation of microglia and the level of inflammation factors, which ultimately lead to the amelioration of SN-striatal dopaminergic neurons and behavioral performance in PD model mice.

Résumé

To investigate the effect of Zhiwei Fuwei Pills (ZWFW) on the expression of mammalian target of rapamycin (mTOR)/autophagy key molecule yeast Atg6 homologue (Beclin1)/microtubuleassociated protein 1 light chain 3 (LC3) signaling axis key molecules in gastric antrum tissue of rats with precancerous gastric lesions (PLGC). METHODS: SPF SD rats were randomly divided into normal group, model group, folic acid group, ZWFW low-dose, medium-dose, high-dose group. In addition to the normal group, the model group, folic acid group, ZWFW low-dose, medium-dose and high-dose groups, were used to establish the PLGC rat model by five factors compound modeling methods: N-methyl-N ' - nitro-n-nitroguanidine (MNNG) combined with hunger and satiation, ethanol intragastric administration, free drinking of ammonia and ranitidine feed. The rats were treated with normal saline, folic acid tablet aqueous solution (0.002 g/kg), ZWFW low-dose, medium-dose, high-dose aqueous solution (0.42, 0.84, 1.67 g/kg) for 4 weeks, and the stomach was removed by laparotomy. Hematoxylineosin (HE) staining was used to observe the histopathological changes in the antrum of rats, and real-time polymerase chain reaction (real-time PCR), Western blot (WB) and immunohistochemistry (IHC) were used to detect the expression of mammalian target of rapamycin mTOR, yeast Atg6 homologue 1 (Beclin1), microtubule-associated protein 1 light chain 3β (LC3B) mRNA and protein in the antrum of rats. RESULTS: Compared with the normal group, the Gastric antrum tissue of the model group was distended, thinner gastric wall, palegastric mucosa, atrophic and flat folds, disordered course and nodules and vegetations were visible. HE staining showed that compared with the normal group, the gastric mucosal glands in the model group were crowded and disordered, and the cell morphology was different, including a large number of goblet cells, basophilic cytoplasm, large, hyper-chromatic and irregular nuclei, and mucosal muscle infiltration and destruction. Compared with the model group, treated by ZWFW can significantly improve the pathological manifestations of gastric mucosal gland structure disorder and cell atypia. Compared with the normal group, mTOR mRNA and protein expression were significantly increased (P< 0.05) and Beclin1 and LC3B mRNA and protein expression were significantly decreased (P<0.05) in the antral tissue of rats in the model group; compared with the model group, mTOR mRNA and protein expression were decreased (P<0.05) in the medium and high dose groups of ZWFW, Beclin1 and LC3B protein expression in the antral tissue of rats in the low dose group of ZWFW and Beclin1 and LC3B mRNA and protein expression were increased (P<0.05) in the medium and high dose groups. CONCLUSION: Zhiwei Fuwei Pills can significantly improve the abnormal histopathological findings of gastric mucosa in PLGC model rats, and the mechanism may be related to the down-regulation of mTOR expression, up-regulation of Beclin1 and LC3B expression and then promoting autophagy.

Résumé

Mammalian target of rapamycin (mTOR) regulates cell survival, proliferation, and metabolism. Alzheimer's disease (AD) is a common neurodegenerative disease with a complex pathogenesis and is closely related to aging. Studies have found that the pathological development of AD is often accompanied by changes in mTOR activity, but the role of mTOR in the pathogenesis of AD is not clear. In this paper, the complex of mTOR and its signaling pathways are first introduced, focusing on the effects of mTOR signaling pathways on synaptic plasticity and memory function, autophagy, βamyloid-β (Aβ), Tau protein and brain insulin resistance and other AD pathological features, secondly, the regulatory effects of mTOR signaling pathways in anti - aging and life prolongation are described, and finally the application of mTOR inhibitors in AD pathological research is introduced to provide new ideas for delaying and improving AD.

Résumé

ObjectiveTo explore the mechanism of Huangqisan (HQS) in regulating autophagy to alleviate hepatic steatosis and improve non-alcoholic fatty liver disease (NAFLD) based on adenosine 5'-monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signaling pathway. MethodThe main chemical components and targets of HQS and NAFLD-related targets were collected from database and the intersection targets were used for Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. The protein-protein interaction (PPI) network was constructed, and in vivo experimental verification was conducted. Sixty C57BL/6J male mice were randomly divided into normal control group (NCD), model group high-fat diet (HFD), metformin group (MET, 0.25 g·kg-1), low-dose Huangqisan group (HQS-L, 0.5 g·kg-1), and the high-dose Huangqisan group (HQS-H, 1 g·kg-1), with 12 mice in each group after a one-week acclimatization period. NAFLD model was induced by HFD, and intragastric administration was performed at the same time, once a day for 13 weeks. Random blood glucose, serum total cholesterol (TC), triglyceride (TG), non-esterified fatty acid (NEFA), low density lipoprotein-chdesterol (LDL-C) levels, and liver TG content were determined. The liver weight was weighed, and liver index was calculated. Hematoxylin-eosin (HE) staining, oil red O staining, transmission electron microscope (TEM), real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and Western blot were used to verify the effect and reveal the potential mechanism of C57BL/6J mice in vivo. ResultThrough network pharmacology analysis, combined with previous studies, it was predicted that HQS may improve NAFLD by regulating autophagy via the AMPK/mTOR signaling pathway. The result of in vivo experiment showed that, as compared with NCD group, random blood glucose, body weight, serum TC, LDL-C, NEFA, liver weight, liver index, and liver TG content of mice in the HFD groups were significantly increased (P<0.01). HE staining showed massive lipid droplets (LDs) vacuolated, oil red O staining showed lipid accumulation in liver cells, and no obvious autophagosomes and autolysosome were observed under TEM. The relative mRNA expression of LC3A、LC3B、AMPKα1 and protein expression of AMPK, phosphory phosphorylated(p)-AMPK, and p-AMPK/AMPK were significantly down-regulated (P<0.01), while the protein expression of microtubule-associated protein 1 light chain 3 (LC3)Ⅱ/Ⅰ and p-mTOR was significantly up-regulated (P<0.01). As compared with HFD groups, liver weight, serum TG, and NEFA levels in HQS-L and HQS-H groups were significantly deceased (P<0.05, P<0.01). HE staining and oil red O staining showed the improvement of liver pathological changes after HQS administration. Under TEM, a small amount of autophagosome and autolysosome were observed. Besides, liver index was significantly decreased in the HQS-L group (P<0.01), and random blood glucose, serum TC level and liver TG content were significantly decreased in the HQS-H group (P<0.05). The results of Western blot and Real-time PCR showed that the mRNA expression of LC3A and LC3B and the protein expression of LC3Ⅱ/Ⅰ, p-AMPK, and p-AMPK/AMPK were significantly up-regulated (P<0.01), while the mRNA expressions of p62 and protein expression of p62 and p-mTOR were significantly down-regulated (P<0.05, P<0.01). ConclusionHQS may promote autophagy and restore autophagy flux via the AMPK/mTOR signaling pathway to alleviate hepatic steatosis improving NAFLD.

MethodForty male APP/PS1 transgenic mice aged four months were randomly divided into a model group and a model + DHYZ group (2.5 g·kg-1), with 20 mice in each group. Forty C57BL/6J mice with the same background and same age were randomly divided into a control group and a control + DHYZ group (2.5 g·kg-1), with 20 mice in each group. The mice in the control group and the model group were administered with an equal volume of sterilized normal saline by gavage, once a day for 150 days. Novel object recognition test and step-down test were performed to evaluate the learning and memory ability of mice. The expression of glial fibrillary acidic protein (GFAP) in astrocytes was detected by immunofluorescence and Western blot. High-performance liquid chromatography (HPLC) was used to detect adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine monophosphate (AMP) in brain tissues of mice, and the data obtained were used to calculate energy charge (EC) levels. The phosphorylation levels of liver kinase B1 (LKB1), adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK), UNC-51-like kinase 1 (ULK1), and mammalian target of rapamycin (mTOR) and the expression levels of autophagy-related proteins Beclin-1, microtuble-associated protein 1 light chain 3 (LC3)-Ⅱ/LC3-Ⅰ, and p62 in mouse brain were measured by Western blot. ResultCompared with the control group, the model group showed decreased novel object recognition index, shortened retention latency, increased error times in the step-down test, up-regulated protein expression of GFAP, decreased content of ATP, ADP, and EC in brain tissues, elevated AMP , increased levels of p-AMPK, p-LKB1, and p-mTOR, and protein expression of p62 , and down-regulated p-ULK1 level and protein expression of Beclin-1 and LC3-Ⅱ/LC3-Ⅰ(P<0.01), while the above experimental indexes were not significantly different in the control + DHYZ group. Compared with the model group, the model + DHYZ group showed increased novel object recognition index(P<0.05), prolonged retention latency(P<0.01), decreased error times(P<0.01) in the step-down test, reduced protein expression of GFAP(P<0.05), increased content of ATP, ADP, and EC in brain tissues (P<0.05, P<0.01), decreased AMP content(P<0.05), reduced p-AMPK, p-LKB1, and p-mTOR levels and protein expression of p62, and up-regulated p-ULK1 level and protein expression of Beclin-1 and LC3-Ⅱ/LC3-Ⅰ(P<0.01). ConclusionBy protecting astrocytes, DHYZ can improve energy metabolism and autophagy disorder in AD mice to improve the learning and memory ability of model mice.

Résumé

@#Vascular malformations, which mainly occur in the head and neck region, are a group of congenital disorders that cannot involute and dilate gradually as patients grow. Traditional therapeutic strategies for vascular malformations include laser therapy, sclerotherapy, interventional embolization, surgical resection, etc. However, for some cases with a relatively larger range of lesions, traditional therapeutic strategies might fall short of the goals. With the development of molecular genetics, gene mutations are currently recognized as the root cause of the occurrence of vascular malformations. The progression of vascular malformation lesions is further promoted by the activation of related pathways. Low-flow vascular malformations mainly involve activation of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway, whereas high-flow vascular malformations mainly involve activation of the rat sarcoma (RAS)/rapidly accelerated fibrosarcoma (RAF)/mitogen-activated protein kinase kinase (MAPKK)/extracellular-signal regulated protein kinase (ERK) pathway. Targeted drugs against relevant gene mutations and signaling pathways have also been applied in the treatment of vascular malformations, and previous studies have shown that the mTOR inhibitor rapamycin is effective and now widely used in the treatment of low-flow vascular malformations. The PI3K inhibitor alpelisib is also promising in the treatment of venous malformations, and the MAPKK inhibitor trametinib has shown good results in the treatment of arteriovenous malformations. Therefore, traditional therapies supplemented by targeted drugs may bring new breakthroughs to the treatment of vascular malformations.
