Objective:To investigate the effect of interleukin 6/Janus kinase 2/signal transducer and activator of transcription 3(IL-6/JAK2/STAT3)on the biological behavior of oral squamous cell carcinoma(OSCC).Methods:OSCC cells were transfected with the designed lentiviral vector plasmid pGMLV-SB3(experimental group)and the corresponding negative control plasmid pGMLV-SB3-shNC(control group);48 hours after transfection,a liposome transfection kit(Sigma,USA)was used for lentivirus packaging;after virus packaging,a medium containing pGMLV-SB3 lentiviral vector was added and cultured for 24 h;the cells were harvested,and RNA was extracted;Transwell chamber assay(Sigma,USA)was used to detect cell migration and invasion ability;dot-enzyme-linked immunosorbent assay(ELISA)kit was used to detect the level of interleukin 6(IL-6)in the culture supernatant,while serum IL-6 level was measured by ELISA.Results:The expressions of IL-6,JAK2,and STAT3 in the experimental group were significantly raised,as compared to the control group(P<0.05);the apoptosis rate of OSCC cells in the experimental group,which was detected by flow cytometry 48 h after transfection,was significantly higher than that of cells in the control group(P<0.05);and there was a significant improvement in the experimental group’s cell migration and invasion ability,as compared to that of the control group(P<0.05).Conclusion:The IL-6/JAK2/STAT3 signaling pathway plays an important role in the migration and invasion of OSCC cells.Inhibiting the expression of IL-6 can inhibit the growth and proliferation of OSCC cells as well as reduce their ability to invade and migrate.These results provide a new target for the treatment of OSCC. 展开更多

Objective:To investigate the effect of MMP-9 inhibitor(Mki67)on the biology of human oral squamous cell carcinoma SCC15 cell line and to explore its mechanism of action through PI3K/Akt signaling pathway.Methods:SCC15 cells were extracted,and the supernatant was discarded.The cells were then rinsed twice with PBS,and 0,2.5,5,and 10μL of Mki67(50 mg/mL)were added to the culture respectively.The inhibition rate of cell proliferation was detected by 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide(MTT)method,and the cell migration was measured by Transwell chamber test.The cell apoptosis rate was detected by cytometry,and the p-Akt protein content in the cells of each group was determined by a double-antibody sandwich enzyme-linked immunosorbent assay(ELISA)kit.Results:The cell proliferation rates of the 2.5μL,5μL,and 10μL dose groups were all lower than the 0μL group(P<0.05)before treatment,and the cell proliferation rates in the 2.5μL,5μL,and 10μL dose groups decreased overtime(P<0.05).After 24 h,with the increase of Mki67 concentration,the number of migration and invasion gradually decreased(P<0.05),and the number of apoptosis gradually increased(P<0.05);besides,the relative expression of MMP-9,PI3K,and Akt mRNA decreased gradually(P<0.05),and the expression level of Akt mRNA was not statistically significant(P>0.05).Conclusion:MMP-9 inhibitor(Mki67)can inhibit the proliferation and migration of SCC15 cell line and induce apoptosis,and its mechanism of action may be related to the inhibition of PI3K/Akt signaling pathway. 展开更多
