RESUMEN
Objective:To observe effect of ginsenoside Rh2 (GRh2) on the invasion and migration of colon cancer resistant cells HCT116/L-OHP and its specific mechanism. Method:Cell counting kit-8 (CCK-8) assay was used to detect the inhibitory effect of different concentrations of GRh2 (0, 2.5, 5, 10, 20, 40 mg·L-1) on HCT116/L-OHP cell proliferation, scratch assay, Transwell assay and adhesion assay were used to detect the effects of GRh2 (0, 2.5, 5, 10 mg·L-1) on cell migration, invasion and adhesion. The protein expression levels of E-cadherin and matrix metalloproteinase-9(MMP-9) were examined by Western blot. Result:Compared with control group, GRh2(5, 10, 20, 40 mg·L-1) significantly inhibited the proliferation of HCT116/L-OHP cells in a dose-dependent manner(PP2 group (5, 10 mg·L-1) was significantly decreased (PP2 group was significantly decreased (PP2 group was significantly reduced (PP2 (10, 20, 30 mg·L-1) promoted E-cadherin protein expression (PPPConclusion:GRh2 can significantly inhibit the invasion and migration of HCT116/L-OHP in colon cancer cells, and its potential mechanism may be related to the promotion of E-cadherin and the inhibition of MMP-9 expression in a dose-dependent manner.
RESUMEN
Annexin A3(ANXA3), is a crucial member of the membrane associated protein superfamily, whose function research is still insufficient. Previous researches have confirmed that Annexin A3 is involved in a variety of cellular processes, but its function is still unclear. Accumulating evidences suggested that Annexin A3 is closely related to various malignant tumors, and plays an important role in tumor development, metastasis, invasion and drug resistance. Therefore, Annexin A3 is expected to be a new therapeutic target for malignant tumors. This article provided an overview about the role of Annexin A3 in malignant tumors.
