Exosome-Transmitted miR-224-5p Promotes Colorectal Cancer Cell Proliferation via Targeting ULK2 in p53-Dependent Manner / 生物医学与环境科学（英文）

OBJECTIVE@#To investigate the role and molecular mechanism of exosomal miR-224-5p in colorectal cancer (CRC).@*METHODS@#The miR-224-5p expression in CRC patient tissues and cell-derived exosomes was measured by laser capture microdissection and qRT-PCR, respectively. Dual-luciferase reporter gene assay was used to determine the target gene of miR-224-5p. The protein expressions of p53 and unc-51 like kinase 2 (ULK2) in CRC cells were detected by western blot. Flow cytometry was used to detect cell cycle and apoptosis. Cell proliferation was measured by CCK8 and EdU assay.@*RESULTS@#The miR-224-5p expression was upregulated in CRC tissues and increased progressively with the rise of CRC stage. CRC cells secreted extracellular miR-224-5p mainly in an exosome-dependent manner, and then miR-224-5p could be transferred to surrounding tumor cells to regulate cell proliferation in the form of autocrine or paracrine. Moreover, ULK2 was characterized as a direct target of miR-224-5p and was downregulated in CRC tissues. Interestingly, ULK2 inhibited CRC cell proliferation in a p53-dependent manner. Furthermore, exosome-derived miR-224-5p partially reversed the proliferation regulation of ULK2 on CRC cells.@*CONCLUSION@#Our findings demonstrate that exosome-transmitted miR-224-5p promotes p53-dependent cell proliferation by targeting ULK2 in CRC, which may offer promising targets for CRC prevention and therapy.

Research advances on the role of ACSL3 in the atherosclerosis / 生理学报

Lipids droplets are organelles that store neutral lipids and are closely related to lipid accumulation. Long chain acyl-coenzyme A synthetase 3 (ACSL3) is a lipid droplet-associated protein mainly distributed in the cell membrane, endoplasmic reticulum, and intracellular lipid droplets, and its distribution depends on cell type and fatty acid supply. ACSL3 is a key regulator of fatty acid metabolism that is closely related to intracellular lipid accumulation, and plays an important role in various pathophysiological processes such as lipid droplet synthesis and lipid metabolism, cellular inflammation, and ferroptosis. This paper mainly reviews the role of ACSL3 in lipid synthesis, ferroptosis, and inflammatory response, with focus on the mechanism of its role in lipid accumulation in atherosclerosis, and provides new ideas for exploring potential therapeutic targets in atherosclerotic diseases.

Mechanism of Gegen Qinlian Decoction in improving glucose metabolism in vitro and in vivo by alleviating hepatic endoplasmic reticulum stress / 中国中药杂志

This study investigated the mechanism of Gegen Qinlian Decoction(GQD) in improving glucose metabolism in vitro and in vivo by alleviating endoplasmic reticulum stress(ERS). Molecular docking was used to predict the binding affinity between the main effective plasma components of GQD and ERS-related targets. Liver tissue samples were obtained from normal rats, high-fat-induced diabetic rats, rats treated with metformin, and rats treated with GQD. RNA and protein were extracted. qPCR was used to measure the mRNA expression of ERS marker glucose-regulated protein 78(GRP78), and unfolded protein response(UPR) genes inositol requiring enzyme 1(Ire1), activating transcription factor 6(Atf6), Atf4, C/EBP-homologous protein(Chop), and caspase-12. Western blot was used to detect the protein expression of GRP78, IRE1, protein kinase R-like ER kinase(PERK), ATF6, X-box binding protein 1(XBP1), ATF4, CHOP, caspase-12, caspase-9, and caspase-3. The calcium ion content in liver tissues was determined by the colorimetric assay. The ERS-HepG2 cell model was established in vitro by inducing with tunicamycin for 6 hours, and 2.5%, 5%, and 10% GQD-containing serum were administered for 9 hours. The glucose oxidase method was used to measure extracellular glucose levels, flow cytometry to detect cell apoptosis, glycogen staining to measure cellular glycogen content, and immunofluorescence to detect the expression of GRP78. The intracellular calcium ion content was measured by the colorimetric assay. Whereas Western blot was used to detect GRP78 and ERS-induced IRE1, PERK, ATF6, and eukaryotic translation initiation factor 2α(eIF2α) phosphorylation. Additionally, the phosphorylation levels of insulin receptor substrate 1(IRS1), phosphatidylinositol 3-kinase regulatory subunit p85(PI3Kp85), and protein kinase B(Akt), which were involved in the insulin signaling pathway, were also measured. In addition, the phosphorylation levels of c-Jun N-terminal kinases(JNKs), which were involved in both the ERS and insulin signaling pathways, were measured by Western blot. Molecular docking results showed that GRP78, IRE1, PERK, ATF4, and various compounds such as baicalein, berberine, daidzein, jateorhizine, liquiritin, palmatine, puerarin and wogonoside had strong binding affinities, indicating that GQD might interfere with ERS-induced UPR. In vivo results showed that GQD down-regulated the mRNA transcription of Ire1, Atf6, Atf4, Grp78, caspase-12, and Chop in diabetic rats, and down-regulated GRP78, IRE1, PERK, as well as ERS-induced apoptotic factors ATF4 and CHOP, caspase-12, caspase-9, and caspase-3, while up-regulating XBP1 to enhance adaptive UPR. In addition, GQD increased the calcium ion content in liver tissues, which facilitated correct protein folding. In vitro results showed that GQD increased glucose consumption in ERS-induced HepG2 cells without significantly affecting cell viability, increased liver glycogen synthesis, down-regulated ATF6 and p-eIF2α(Ser51), and down-regulated IRE1, PERK, and GRP78, as well as p-IRS1(Ser312) and p-JNKs(Thr183/Tyr185), while up-regulating p-PI3Kp85(Tyr607) and p-Akt(Ser473). These findings suggested that GQD alleviates excessive ERS in the liver, reduces insulin resistance, and improves hepatic glucose metabolism in vivo and in vitro.

KIF22 promotes the proliferation and glycolysis of melanoma by activating EGFR/STAT3 signaling

Abstract Objectives Melanoma is one of the leading causes of cancer death. Kinesin Family member 22 (KIF22) is essential for the invasion of melanoma cells, but the role and mechanism of KIF22 in the proliferation and glycolysis in melanoma remains unknown. Methods KIF22 expression in melanoma tissues and the relationship between KIF22 high expression and overall survival rate in patients with melanoma were analyzed using the Tnmplot database. KIF22 expression in melanoma cells was examined by western blot. Then, KIF22 was silenced and CCK-8 assay, EDU staining and flow cytometry analysis were adopted for assessing cell proliferation and apoptosis. In addition, the glycolysis metabolism of melanoma cells was reflected by detecting Extracellular Acidification Rates (ECAR) and Oxygen Consumption Rates (OCR). The expression of proteins related to apoptosis, glycolysis and EGFR/STAT3 signaling was tested by western blot. Subsequently, melanoma cells were treated with EGF or Colivelin to further elucidate the regulatory effect of KIF22 on EGFR/STAT3 signaling. Results KIF22 expression was notably upregulated in melanoma tissues and cells, and KIF22 high expression was associated with a poor prognosis. Moreover, KIF22 insufficiency suppressed proliferation and accelerated apoptosis of melanoma cells. Additionally, glycolysis was reduced by KIF22 depletion, evidenced by the decreased ECAR and increased OCR, accompanied by the downregulated expression of HK2, PKM2 and LDHA. Importantly, the impacts of KIF22 depletion on the progression of melanoma were partially attenuated after EGF or Colivelin treatment. Conclusion Collectively, KIF22 knockdown suppressed the proliferation and glycolysis and facilitated the apoptosis of melanoma cells by inactivating EGFR/STAT3 signaling.

Evaluation of porcine urine-derived cells as nuclei donor for somatic cell nuclear transfer

Background@#Somatic cell nuclear transfer (SCNT) is used widely in cloning, stem cell research, and regenerative medicine. The type of donor cells is a key factor affecting the SCNT efficiency. @*Objectives@#This study examined whether urine-derived somatic cells could be used as donors for SCNT in pigs. @*Methods@#The viability of cells isolated from urine was assessed using trypan blue and propidium iodide staining. The H3K9me3/H3K27me3 level of the cells was analyzed by immunofluorescence. The in vitro developmental ability of SCNT embryos was evaluated by the blastocyst rate and the expression levels of the core pluripotency factor. Blastocyst cell apoptosis was examined using a terminal deoxynucleotidyl transferase dUTP nick end-labeling assay. The in vivo developmental ability of SCNT embryos was evaluated after embryo transfer. @*Results@#Most sow urine-derived cells were viable and could be cultured and propagated easily. On the other hand, most of the somatic cells isolated from the boar urine exhibited poor cellular activity. The in vitro development efficiency between the embryos produced by SCNT using porcine embryonic fibroblasts (PEFs) and urine-derived cells were similar.Moreover, The H3K9me3 in SCNT embryos produced from sow urine-derived cells and PEFs at the four-cell stage showed similar intensity. The levels of Oct4, Nanog, and Sox2 expression in blastocysts were similar in the two groups. Furthermore, there is a similar apoptotic level of cloned embryos produced by the two types of cells. Finally, the full-term development ability of the cloned embryos was evaluated, and the cloned fetuses from the urine-derived cells showed absorption. @*Conclusions@#Sow urine-derived cells could be used to produce SCNT embryos.

Research Progress of ACSL3 and Related Diseases / 中国生物化学与分子生物学报

Lipid droplets are important organelles that have the function of storing intracellular lipid and regulation of cell lipid homeostasis. A variety of lipid droplet-related proteins exists on the surface of lipid droplets. The acyl CoA long chain synthetase 3 (ACSL3) of the long chain acyl-CoA synthetase family is a kind of lipid droplet-related protein and an essential enzyme in the process of biosynthesis. ACSL3, which plays different roles in a variety of pathophysiological processes such as the synthesis of lipid droplets, the regulation of autophagy, and cell iron death, is widely distributed on the surface of lipid droplets in most cells. In addition, many studies have shown that ACSL3 is also widely involved in the occurrence and development of atherosclerosis, nonalcoholic fatty liver disease, diabetes, and tumors. At present, domestic research on ACSL3 is relatively focused on the relationship between ACSL3 and animal breeding and growth. However, the reports on the mechanism of ACSL3 in lipid metabolism and the relationship between ACSL3 and diseases are relatively rare. This article summarizes the structure of ACSL3 and its mechanism in cell lipid metabolism and related diseases, which may provide a new theoretical basis for the prevention and treatment of atherosclerosis, non-alcoholic fatty liver disease, diabetes and other ACSL3 related diseases. This article also further explores the role of ACSL3 in the process of lipid droplet synthesis, autophagy, and iron death.

Whole blood viscosity （high，medium，low），serum inflammatory factors ［tumor necrosis factor-alpha（TNF-<italic>α</italic>），interleukin-1<italic>β</italic>（IL-1<italic>β</italic>），interleukin-6（IL-6），pain mediators［endothelin-1（ET-1），prostaglandin E₂（PGE₂），cyclooxygenase-2（COX-2）］ were detected. The clinical efficacyand，recurrence rate followed up for 12 and 24 months was was observed. The type and time of adverse reactions were recorded during the study. Result:After treatment，the total effective rate in the observation group was 98.0%（49/50） higher than that 82.0%（41/50） in the control group（<italic>P</italic><0.05）. After 12 months of follow-up，the recurrence rate in the observation group was 23.9%（11/46） lower than that 52.5%（21/40） in the control group （<italic>χ</italic>²＝5.193，<italic>P</italic><0.05）. After 24 months of follow-up，the recurrence rate in the observation group was 43.9%（18/41） lower than that that 80.6%（29/36） in the control group（<italic>P</italic><0.05）. Compared with the control group after treatment，SF-MPQ，ODI，TCM symptoms，whole blood viscosity，TNF-<italic>α</italic>，IL-1<italic>β</italic>，IL-6，ET-1，PGE₂ and COX-2 were significantly reduced in the observation group（<italic>P</italic><0.05）. The incidence of adverse reactions in the observation group was 2.0%（1/50） lower than that 52.0%（26/50） in the control group（<italic>χ</italic>²＝6.264，<italic>P</italic><0.05）. Conclusion:Modified Shenfuwan can significantly improve the short-term and long-term clinical efficacy of patients with lumbar disc herniation due to kidney deficiency and cold coagulation syndrome，and the incidence of adverse reactions is low.

Effect of preoperative application of artificial tears combined with recombinant bovine basic fibroblast growth factor on ocular surface function and inflammatory factor levels in patients with cataract and dry eye / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To explore the effect of artificial tears combined with recombinant bovine basic fibroblast growth factor(rbFGF)on ocular surface function and inflammatory factors in patients with cataract complicated with xerophthalmia.<p>METHODS: A total of 118 cataract patients(118 eyes)with dry eyes treated in our hospital from February 2019 to February 2020 were randomly divided into control group(<i>n</i>=59)and observation group(<i>n</i>=59). The control group was treated with artificial tears before operation and the observation group was treated with artificial tears combined with rbFGF before operation. The clinical symptom score, ocular surface function index \〖ocular surface disease index(OSDI)questionnaire score, break up time(BUT), schirmer Ⅰ test(SⅠt), fluorescein stain test(FL)\〗, inflammatory factors in tears \〖interleukin-6(IL-6), tumor necrosis factor α(TNF-α)\〗 and oxidative stress indexes \〖malondialdehyde(MDA), lipid peroxide(LPO), superoxide dismutase(SOD), total antioxidant capacity(TAC)\〗 were compared between the two groups before and after treatment. The random walking model was used to evaluate the ocular surface function and the level of inflammatory factors in tears of the two groups.<p>RESULTS: Before treatment, there was no significant difference in clinical symptom score, OSDI, BUT, SⅠt, FL, IL-6, TNF-α, MDA, SOD, LPO and TAC between the two groups. Thirty days after treatment, the clinical symptom score, OSDI, FL, TNF-α, IL-6, MDA and LPO levels in two groups were significantly decreased, while the levels of BUT, SⅠt, SOD and TAC were significantly increased. The improvement of clinical symptom score, ocular surface function, inflammatory factors and oxidative stress in the observation group were significantly better than that in the control group.<p>CONCLUSION: Preoperative intervention with artificial tears combined with rbFGF can significantly improve the ocular surface function of cataract patients with xerophthalmia, reduce the level of inflammatory factors in tears, improve the symptoms of xerophthalmia, and provide reference for the clinical treatment of cataract with xerophthalmia.
