Functions of HIV-1 Tat and its association with diseases / 中国生物制品学杂志

@#Acquired immune deficiency syndrome,or AIDS,has been a major infectious disease that troubles the public health in a global scale. Human immunodeficiency virus type 1(HIV-1)is the causative reagent responsible for AIDS development. Even though the highly active anti-retroviral therapy(HAART,or the cocktail therapy)that has been widely applied could effectively suppress the infection and replication of HIV-1,the infected people suffer from other related diseases,such as the HIV-associated neurocognitive disorder(HAND). This paper mainly focused on the function of an important regulatory protein of HIV-1,trans-activator of transcription(Tat),and its correlation with HIV-1 replication and HAND development,so as to clarify the importance of developing anti-AIDS drugs targeting Tat protein

Effect and mechanism of berberine-induced ferroptosis in osteosarcoma cells / 中国药房

OBJECTIVE To investigate the effect of berberine on ferroptosis in MG63 osteosarcoma cells and its mechanism. METHODS Using cells without drug treatment as control， the cell viability， proliferation， the related indexes of ferroptosis [nuclear proliferation associated-antigen （Ki67）， mitochondrial ultrastructure， ferric ion （Fe2+）， reactive oxygen species （ROS）， malondialdehyde （MDA）， and glutathione （GSH）]， the protein expression of signal transducer and activator of transcription 3 （STAT3）， tumor protein 53 （p53）， and solute carrier family 7 member 11 （SLC7A11） were detected after being treated with different concentrations of berberine. Cells were transfected with p53 siRNA and then assigned to the control group， p53 siRNA group， berberine group， and p53 siRNA+berberine group to explore the role of p53 in berberine-induced ferroptosis. After 24 h incubation with 10.0 μmol/L berberine， the protein expressions of p53 and SLC7A11， the levels of mitochondrial membrane potential， GSH， and MDA content were determined. Cells were transfected with STAT3 overexpressed plasmid and then assigned to the control group， berberine group， STAT3 group， and STAT3+berberine group to explore the effect of STAT3 on the regulation of the p53/SLC7A11 pathway. After 24 h incubation with 10 μmol/L berberine， the protein expressions of p-STAT3， STAT3， p53， and SLC7A11 were detected. RESULTS Compared with the control cell， the concentrations of 2.5， 5.0 and 10.0 μmol/L berberine could reduce the cell viability and expression of Ki67， and induce the morphological changes in ferroptosis-related mitochondria， increase the levels of Fe2+， ROS and MDA， and the protein expression of p53， reduce the level of GSH， the binding activity of STAT3 with DNA， and the protein expressions of p-STAT3 and SLC7A11； the above differences were statistically significant （P＜ 0.05 or P＜0.01）. Compared with the berberine group，significantly down-regulated p53 protein expression and MDA level， up-regulated SLC7A11 protein expression， and increased mitochondrial membrane potential and GSH level were observed in the p53 siRNA+berberine group （P＜0.01）. Compared with the berberine group， the protein expressions of p-STAT3， STAT3， and SLC7A11 in the STAT3+berberine group were significantly increased （P＜0.01）， while the protein expression of p53 was significantly decreased （P＜0.01）. CONCLUSIONS Berberine can induce the ferroptosis of MG63 cells by mediating STAT3/p53/SLC7A11 signaling pathway.

Research progress on invasive cervical resorption / 口腔疾病防治

@#Tooth absorption can be divided into physiological absorption and pathological absorption. Root absorption of mature deciduous teeth is physiological absorption. Pathological absorption includes internal absorption and external absorption. Internal absorption, also known as intramedullary absorption, includes inflammatory absorption and alternative absorption. External tooth absorption originates from the outer surface of the root or the neck of the tooth and can be divided into inflammatory absorption, alternative absorption, pressure resorption and invasive cervical resorption. Invasive cervical resorption (ICR) is pathological damage caused by many factors, which usually begins in the cemento-enamel junction and extends peripherally or horizontally in the dentin. It hardly invades the pulp. Orthodontic devices, trauma, bleaching, systemic diseases, and the use of certain medications can all lead to invasive cervical resorption. The clinical manifestations of ICR are usually asymptomatic or not obvious, and most of which are found in imaging examinations. Because caries and internal absorption are often misdiagnosed through plain apical radiography, cone beam computed tomography (CBCT) can help to better understand the situation of invasive cervical resorption. Because the pathogenesis and etiology of invasive cervical resorption are not fully understood, clinical negligence and inadequate treatment of invasive cervical resorption can even cause unnecessary tooth loss. This article reviews the latest research progress on the histopathologic features, pathogenic mechanism, susceptibility factors, diagnosis and treatment of ICR, with special emphasis on susceptibility factors and their mechanisms.

ObjectiveTo investigate the effect and potential mechanism of Dihuangyin on 2， 4-dinitrochlorobenzene （DNCB） -induced model mice with atopic dermatitis （AD）. MethodA mouse model with AD was established by repeatedly stimulating the back skin of mice with DNCB. After successful modeling， the mice were randomly divided into model group， Runzao group （0.78 g·kg-1）， and high， medium， and low dose （40.30， 20.15， and 10.08 g·kg-1） groups of Dihuangyin， with 12 mice in each group， and the blank group consisted of 12 mice， 72 in total. The administration groups were given the corresponding liquid by dose， and the blank group and model group were given the same dose of pure water by intragastric administration， once a day. The skin lesions and scratching times of mice were observed after continuous administration for two weeks. The back skin lesions of mice were stained with hematoxylin-eosin （HE） and toluidine blue to observe the pathology. The contents of serum immunoglobulin E （IgE）， interleukin-4 （IL-4）， interleukin-6 （IL-6）， and interferon-γ （IFN-γ） were detected by enzyme-linked immunosorbent assay （ELISA）. The mRNA expression levels of IFN-γ， IL-4， IL-6， Janus kinase 1 （JAK1）， and transcriptional activator 3 （STAT3） in skin lesion tissue were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The expressions of JAK1， phosphorylation（p）-JAK1， STAT3， and p-STAT3 proteins in skin lesion tissue were detected by Western blot. ResultCompared with the blank group， the back skin of the model group showed large-scale scab， dryness， erosion， hypertrophy with scratching， epidermal hyperplasia with hyperkeratosis and parakeratosis， hyperacanthosis with edema， and a large number of mast cell infiltration in the dermis， some of which were degranulated. The contents of IgE， IL-4， IL-6， and IFN-γ in the serum of mice were significantly increased （P<0.01）， and the protein expression levels of p-JAK1， STAT3， and p-STAT3 and mRNA expressions of IL-4， IL-6， IFN-γ， JAK1， and STAT3 in skin lesion tissue were significantly increased （P<0.01）. Compared with the model group， only a small amount of dryness and desquamation were observed in the back skin of mice in each administration group， and cell edema was reduced. The inflammatory infiltration was significantly reduced， and the number of mast cell infiltration was significantly decreased. The serum IgE， IL-4， IL-6， and IFN-γ of mice were decreased to varying degrees （P<0.05， P<0.01）. The protein expression levels of p-JAK1， STAT3， and p-STAT3 and mRNA expressions of IL-4， IL-6， IFN-γ， JAK1， and STAT3 in skin lesion tissue were significantly decreased， and the effect of high dose group of Dihuangyin was the best （P<0.01）. ConclusionDihuangyin can improve skin lesions and pruritus in mice with AD， and its mechanism may be related to the effective regulation of cytokines on the helper T cells （Th1）/Th2 axis by interfering with the JAK1/STAT3 signaling pathway and affecting skin barrier function.

Curcumin Induces Cycle Arrest of Colon Cancer HCT116 Cells via JAK1/STAT1/p21 Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the effect of curcumin on the cycle arrest of human colon cancer HCT116 cells and decipher the possible molecular mechanism. MethodThe methyl thiazolyl tetrazolium （MTT） method was employed to examine the effects of curcumin （0， 12.5， 25， 50， 75， 100 μmol·L-1） and 5-fluorouracil （5-FU， 600 μmol·L-1） on the proliferation of HCT116 cells at different time points （24， 48， 72 h）. Flow cytometry was employed to examine the cycle of HCT116 cells treated with curcumin （0， 25， 50， 75 μmol·L-1） and 5-FU. Western blot was employed to determine the expression of proteins in the Janus kinase 1 （JAK1）/signal transducer and activator of transcription 1 （STAT1） /cyclin-dependent kinase inhibitor 1A （p21） pathway in HCT116 cells. The binding of STAT1 to p21 promoter region was detected by chromatin immunoprecipitation （ChIP）. Small interfering RNA （siRNA） was employed to measure the role of STAT1 in regulating the expression of p21 and that of JAK1 in regulating the activation of STAT1 by Western blot and cellular immunofluorescence， respectively. ResultCompared with the blank group， the HCT-116 cells treated with curcumin and 5-FU showed decreased viability （P<0.05）， increased proportions of cells in the G0/G1 phase （P<0.05）， decreased proportions of cells in the S phase and G2/M phase （P<0.05）， down-regulated protein level of phosphorylated p21 （P<0.05）， and up-regulated protein level of p21 （P<0.05）. Compared with the curcumin group， the p21 siRNA+ curcumin group presented decreased proportion of cells in G0/G1 phase （P<0.05）. Compared with the blank group， curcumin elevated the level of phosphorylated STAT1 （p-STAT1） （P<0.05）. Compared with the curcumin group， the curcumin + STAT1 siRNA group showcased up-regulated protein level of p21 in HCT116 cells （P<0.05）. The mechanism study showed that curcumin treatment enhanced the enrichment of STAT1 in the p21 promoter region （P<0.05） compared with the blank group. Compared with the blank group， curcumin up-regulated the level of phosphorylated JAK1 （p-JAK1） （P <0.05）. Compared with the curcumin group， the curcumin + STAT1 siRNA group demonstrated up-regulated protein levels of p-STAT1 and p21 in HCT116 cells （P<0.05）. ConclusionCurcumin may induce the cycle arrest of human colon cancer HCT116 cells by activating the JAK1/STAT1/p21 signaling pathway.

ObjectiveTo investigate the effect of Xuanfei Zhisou prescription on the interleukin-17 （IL-17） signaling pathway in model rats with chronic obstructive pulmonary disease （COPD）. MethodA total of 60 Wistar rats were randomly divided into a blank group （10 rats） and a model group （50 rats）， and COPD model rats were established by tracheal infusion of lipopolysaccharide combined with passive fumigation. After modeling， the rats were divided into the model group， dexamethasone group， and high， medium， and low-dose Xuanfei Zhisou prescription groups （3.6， 1.8， 0.9 g·kg-1·d-1） according to the random number table. Rats in the blank group and model group were given normal saline of 10 mL·kg-1·d-1 by gavage administration， and the intervention groups of Xuanfei Zhisou prescription were given corresponding drugs. Rats in the dexamethasone group were given dexamethasone of 2.57×10-4 g·kg-1·d-1 for 28 days. The level of pulmonary function indexes in rats was measured by a pulmonary function detector. The contents of interleukin-6 （IL-6）， interleukin-8 （IL-8）， IL-17， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） were detected by enzyme-linked immunosorbent assay （ELISA）. The positive expressions of IL-17A， IL-17RA， nuclear factor-κB activator 1 （Act1）， tumor necrosis factor-associated factor 6 （TRAF6）， p-p38 mitogen-activated protein kinase （p-p38 MAPK）， nuclear factor-κB p65 （NF-κB p65）， and phosphorylation were detected by immunohistochemistry （IHC）. The protein expression levels of IL-17A， IL-17RA， Act1， and TRAF6 in the lung tissue were detected by Western blot. The mRNA expressions of IL-17A， IL-17RA， Act1， and TRAF6 in the lung tissue were detected by Real-time polymerase chain reaction （Real-time PCR）. ResultCompared with the blank group， the serum contents of IL-6， IL-8， IL-17， IL-1β， and TNF-α in the model group were significantly increased （P<0.05）， and the flow rate and volume indexes of pulmonary function in the model group were significantly decreased （P<0.05）， while the time indexes and other indexes were significantly increased （P<0.05）. The mRNA and protein expression levels of IL-17A， IL-17RA， Act1， and TRAF6 in pulmonary tissue and the positive expressions of downstream NF-κB p65， p-NF-κB p65， and p-p38 MAPK were increased （P<0.05）. Compared with the model group， the levels of IL-6， IL-8， IL-17， IL-1β， and TNF-α in the serum of all treatment groups were decreased to varying degrees （P<0.05）， and the indexes of pulmonary function were improved to different degrees （P<0.05）. The mRNA and protein levels of IL-17A， IL-17RA， Act1， and TRAF6 and the positive expression of downstream NF-κB p65， p-NF-κB p65， and p-p38 MAPK in high and medium-dose Xuanfei Zhisou prescription groups were significantly decreased （P<0.05）. ConclusionXuanfei Zhisou prescription can effectively resist inflammation of COPD rats. The mechanism may be related to down-regulating the protein expression of IL-17A， IL-17RA， Act1， and TRAF6， inhibiting downstream NF-κB and p38 MAPK signaling pathways， and reducing the release of IL-6， IL-8， TNF-α， IL-17， and IL-1β， thus reducing the airway inflammation response.

Characteristics of STAT Family Association with Breast Cancer and Intervention Effect of Traditional Chinese Medicine / 中国实验方剂学杂志

As the pace of society increases and lifestyles change， the incidence and mortality rates of breast cancer continue to rise. Targeted therapies are now promising in the treatment of breast cancer， and a variety of protein targets have been identified to play an important role in the development of breast cancer. Among them， signal transducer and activator of transcription （STAT） proteins constitute a crucial group that serves as important targets for transducing cellular transcriptional information， which can regulate downstream cell proliferation， apoptosis， cell migration， invasion， angiogenic factors， etc. and then affect the progression of breast cancer. The STAT family is closely associated with the inflammatory response to tumors and plays a landmark role in tumor development as well as in diagnosis and prognosis. The "inflammation-cancer" transformation refers to the process in which the inflammatory microenvironment caused by uncontrolled inflammation promotes normal cells to become cancerous. According to the theory of Chinese medicine， "heat toxicity" in "cancer toxicity" corresponds to inflammation， which is closely related to tumor development. As a major link associated with the inflammatory response， the STAT family has a promising role in the development and treatment of a variety of tumors， but its relevance to breast cancer remains inadequately explored. Chinese medicine has been shown to have good efficacy in the prevention and treatment of breast cancer， and some current studies have shown that the active ingredients and compounds of Chinese medicine have certain intervention effects on breast cancer-related STAT proteins， but there has not been a systematic review. In order to better sort out and summarize the studies on the effects of Chinese herbal medicines based on the STAT family interventions in breast cancer， this paper reviewed the studies on Chinese herbal medicines acting on the STAT family in recent years， aiming to provide new ideas for clinical applications in breast cancer and to provide thoughts for the development of STAT protein-based drugs.

Angioedema after rt-PA infusion led to airway emergency: a case report of rescue treatment with fresh frozen plasma

Abstract The authors report the case of a 71-year-old woman presented to the Emergency Department with acute ischemic stroke. She was treated with rt-PA and interventional endovascular revascularization and developed rapidly progressing angioedema that led to emergency intubation. The standard treatment was not very effective and the swelling improved after infusion of fresh frozen plasma. Angioedema after rt-PA infusion could be a life-threatening emergency that requires quick airway management by skilled professionals. As this condition is triggered by several factors, such as unregulated histamine and bradykinin production, the traditional treatment recommended by the guidelines may not be sufficient and the use of FFP can be considered as a safe and valuable aid.

Specificity and sensitivity of the SeLECT score in predicting late seizures in patients undergoing intravenous thrombolytic treatment and the effect of diabetes mellitus and leukoaraiosis / Especificidade e sensibilidade do escore SeLECT na predição de convulsões tardias em pacientes submetidos a tratamento trombolítico intravenoso e o efeito do diabetes mellitus e leucoaraiose

Abstract Background Seizures after stroke can negatively affect the prognosis of ischemic stroke and cause a decrease in quality of life. The efficacy of intravenous (IV) recombinant tissue plasminogen activator (rt-PA) treatment in acute ischemic stroke has been demonstrated in many studies, and IV rt-PA treatment has been increasingly used around the world. The SeLECT score is a useful score for the prediction of late seizures after stroke and includes the severity of stroke (Se), large artery atherosclerosis (L), early seizure (E), cortical involvement (C), and the territory of the middle cerebral artery (T). However, the specificity and sensitivity of the SeLECTscore have not been studied in acute ischemic stroke patients that received IV rt-PA treatment. Objective In the present study, we aimed to validate and develop the SeLECT score in acute ischemic stroke patients receiving IV rt-PA treatment. Methods The present study included 157 patients who received IV thrombolytic treatment in our third-stage hospital. The 1-year seizure rates of the patients were detected. SeLECT scores were calculated. Results In our study, we found that the SeLECT score had low sensitivity but high specificity for predicting the likelihood of late seizure after stroke in patients administered IV rt-PA therapy. In addition to the SeLECT score, we found that the specificity and sensitivity were higher when we evaluated diabetes mellitus (DM) and leukoaraiosis. Conclusion We found that DM was an independent risk factor for late seizures after stroke in a patient group receiving thrombolytic therapy, and late seizures after stroke were less frequent in patients with leukoaraiosis.

Resumo Antecedentes As convulsões após o AVC podem afetar negativamente o prognóstico do AVC isquêmico e causar uma diminuição na qualidade de vida. A eficácia do tratamento com ativador do plasminogênio tecidual recombinante (rt-PA) intravenoso (IV) no AVC isquêmico agudo foi demonstrada em muitos estudos, e o tratamento com rt-PA IV tem sido cada vez mais usado em todo o mundo. A pontuação SeLECT é uma pontuação útil para a previsão de convulsões tardias após AVC e inclui a gravidade do AVC (Se), aterosclerose de grandes artérias (L), convulsão precoce (E), envolvimento cortical (C) e o território do meio artéria cerebral (T). No entanto, a especificidade e a sensibilidade do escore SeLECT não foram estudadas em pacientes com AVC isquêmico agudo que receberam tratamento IV com rt-PA. Objetivo No presente estudo, objetivamos validar e desenvolver o escore SeLECT em pacientes com AVC isquêmico agudo recebendo tratamento IV com rt-PA. Métodos O presente estudo incluiu 157 pacientes que receberam tratamento trombolítico IV em nosso hospital de terceiro estágio. As taxas de convulsão de 1 ano dos pacientes foram detectadas. Os escores SeLECT foram calculados. Resultados Em nosso estudo, descobrimos que o escore SeLECT apresentou baixa sensibilidade, mas alta especificidade para prever a probabilidade de convulsão tardia após AVC em pacientes que receberam terapia IV com rt-PA. Além do escore SeLECT, descobrimos que a especificidade e a sensibilidade foram maiores quando avaliamos diabetes mellitus (DM) e leucoaraiose. Conclusão Descobrimos que DM foi um fator de risco independente para convulsões tardias após AVC em um grupo de pacientes recebendo terapia trombolítica, e convulsões tardias após AVC foram menos frequentes em pacientes com leucoaraiose.

Abstract By applying the in-silico method, resveratrol was docked on those proteins which are responsible for bone loss. The Molecular docking data between the resveratrol and Receptor activator of nuclear factor-kappa-Β ligand [RANKL] receptors proved that resveratrol binds tightly to the receptors, showed the highest binding affinities of −6.9, −7.6, −7.1, −6.9, −6.7, and −7.1 kcal/mol. According to in-vitro data, Resveratrol reduced the osteoclasts after treating Marrow-Derived Macrophages [BMM] with Macrophage colony-stimulating factor [MCSF] 20ng / ml and RANKL 50ng / ml, with different concentrations of resveratrol (2.5, 10 μg / ml) For 7 days, the cells were treated with MCSF (20 ng / ml) and RANKL (40 ng / ml) together with concentrated trimethyl ether and resveratrol (2.5, 10 μg / ml) within 12 hours. Which, not affect cell survival. After fixing osteoclast cells with formaldehyde fixative on glass coverslip followed by incubation with 0.1% Triton X-100 in PBS for 5 min and after that stain with rhodamine phalloidin staining for actin and Hoechst for nuclei. Fluorescence microscopy was performed to see the distribution of filaments actin [F.actin]. Finally, resveratrol reduced the actin ring formation. Resveratrol is the best bioactive compound for drug preparation against bone loss.

Correlation between Serum Osteoprotegerin/Soluble Receptor Activator of Nuclear Factor-κβ Ligand Levels and the Left Ventricular Diastolic Dysfunction in Type 2 Diabetes / 中山大学学报(医学科学版)

ObjectiveTo study the possible correlation between serum osteoprotegerin （OPG）/soluble receptor activator of the nuclear factor κB ligand （sRANKL） levels and the left ventricular diastolic dysfunction （LADD） in patients with type 2 diabetes mellitus （T2DM）. MethodsTotally 68 T2DM patients and 37 healthy controls were selected. Serum OPG and sRANKL were determined by solid-phase enzyme-linked immunosorbent assay （ELISA）. The left ventricular diastolic function of T2DM patients was measured by transthoracic echocardiography， where E/A < 1 were regarded as LVDD. T2DM patients were further divided into two subgroups according to E/A ratio （E/A≥1.0 and E/A<1）. Spearman correlation analysis， logistic regression and ROC curves were used to assess the possible correlation between serum OPG/sRANKL and LADD in T2DM patients. ResultsCompared with the healthy controls， serum OPG level in T2DM patients was higher with statistically significant difference （P <0.01）， while serum sRANKL level was lower without statistically significant difference （P =0.32）. T2DM patients with E/A<1 had significantly higher OPG level and lower sRANKL level than those with E/A≥1（P <0.01） in subgroup analysis. Spearman correlation analysis showed serum OPG level was negatively correlated with E/A ratio， while sRANKL was positively related with E/A ratio. In single factor logistic regression analyses， serum OPG ［OR （95% CI）=1.068 （1.031， 1.106）， P<0.001］ and sRANKL ［OR （95% CI）=0.976 （0.959， 0.992）， P=0.003］ were significant correlation with LVDD in T2DM patients. ROC curve analysis showed that the sensitivity and specificity of combined OPG and sRANKL in diagnosing T2DM patients LADD were 78.13% and 88.3%， respectively （area under the curve： 0.857； 95% CI=（0.768， 0.946）； P<0.001）. ConclusionsThe elevated OPG and decreased sRANKL levels may be associated with LADD in T2DM patients.

Role of STAT3 activated NLRP3 inflammasomes in BV2 cell inflammatory response induced by maltol aluminum / 环境与职业医学

Background Aluminum activates signal transducer and activator of transcription 3 (STAT3), causing microglial nucleotide-binding and oligomerization domain-like receptors protein 3 (NLRP3) inflammasome activation and inflammatory responses and producing neurotoxicity. Objective To explore the role of STAT3 regulated NLRP3 inflammasomes in the inflammatory response of mouse microglia cell line (BV2) cells induced by maltol aluminum [Al(mal)3]. Methods BV2 cells were assigned to five groups: one control group, three Al(mal)3 exposure groups (low, medium, and high doses at 40, 80, and 160 μmol·L−1 Al(mal)3 respectively), and one C188-9 (STAT3 antagonist) intervention group [10 μmol·L−1 C188-9 +160 μmol·L−1 Al(mal)3]. Cell viability was detected by CCK8. The expression of M1/M2 type markers, i.e. CD68/CD206, STAT3, p-STAT3, NLRP3, cleaved-casepase-1, and apoptosis-associated speck-like protein (ASC) in BV2 cells were detected by Western blotting, and proinflammatory cytokines interleukin (IL)-1β and IL-18, and anti-inflammatory cytokine IL-10 were determined by ELISA. Results The results of cell viability assay showed that cell viability gradually decreased with the increase of Al(mal)3 dose. Compared with the control group, the cell viability of the Al(mal)3 high-dose group was decreased by 18% (P<0.05); compared with the Al(mal)3 high-dose group, the cell viability of the C188-9 intervention group was significantly elevated by 14% (P<0.05). Compared with the control group, the expression levels of CD68 in the Al(mal)3 low-, medium-, and high-dose groups were elevated by 19%, 20%, and 21%, respectively (P<0.05); the expression level of CD206 in the Al(mal)3 high-dose group was decreased by 25% (P<0.05). Compared with the Al(mal)3 high-dose group, the expression level of CD68 in the C188-9 intervention group was reduced by 9% (P<0.05), whereas the expression level of CD206 was elevated by 22% (P<0.05). Compared with the control group, the p-STAT3 protein expression and the p-STAT3/STAT3 ratio in the Al(mal)3 high-dose group increased by 129% and 127%, respectively (P<0.05). Compared with the Al(mal)3 high-dose group, the p-STAT3 protein expression and the p-STAT3/STAT3 ratio in the C188-9 intervention group were decreased by 55% and 54%, respectively (P>0.05). Compared with the control group, the expression level of NLRP3 protein increased by 75% in the Al(mal)3 high-dose group (P<0.05), the expression levels of cleaved-casepase-1 protein increased by 28% and 35% in the Al(mal)3 medium- and high-dose groups (P<0.05), and the expression levels of ASC increased by 22%, 25%, and 53% in the Al(mal)3 low-, medium- and high-dose groups (P<0.05), respectively. Compared with the Al(mal)3 high-dose group, the expression levels of NLRP3, cleaved-casepase-1, and ASC proteins in the C188-9 intervention group decreased by 30%, 19%, and 32%, respectively (P<0.05). Compared with the control group, the levels of IL-1β in the Al(mal)3 medium- and high-dose groups increased by 18% and 21%, respectively (P<0.05), and the level of IL-18 in the Al(mal)3 high-dose group increased by 10% (P<0.05). Compared with the Al(mal)3 high-dose group, the IL-18 levels were reduced by 23% in the C188-9 intervention group (P<0.05). The content of anti-inflammatory factor IL-10 did not differ significantly between groups (P>0.05). Conclusion Aluminum can induce inflammatory responses in BV2 microglia and is predominantly pro-inflammatory, and the mechanism may involve STAT3 regulation of NLRP3 inflammasome secretion of inflammatory factors.
