人參皂苷CK聯(lián)合5-氟尿嘧啶對人胰腺癌PANC-1細胞的增殖、凋亡及上皮間質(zhì)轉(zhuǎn)化的影響
[Abstract]:Aim: to study the effects of ginsenoside CK combined with 5-fluorouracil (5-FU) on proliferation, apoptosis and (EMT) transformation in human pancreatic carcinoma PANC-1 cells. Methods: PANC-1 cells in logarithmic growth period were divided into blank control group, ginsenoside CK group (30 mg/L), 5-FU group (25 mg/L) and combination group (ginsenoside CK 30 mg/L 5-FU 25 mg/L). MTT assay was used to detect the cell proliferation inhibition rate after 24,48,72 h, flow cytometry was used to detect the apoptosis rate after 48 h, enzyme linked immunosorbent assay (Elisa) was used to detect the expression of fibronectin in the cells at 24, 48, 72, 96 h. The expression of vimentin, N-cadherin, E-cadherin, protein kinase (Akt) and phosphorylated Akt (p-Akt) protein were detected by Western blot assay. Results: ginsenoside CK,5-FU and its combination had inhibitory effect on cell proliferation. Compared with the blank control group, ginsenoside CK group, 5-FU group and combination group at the early and late stage of apoptosis, the expression of E-cadherin were significantly increased (P0.05), fibronectin, vimentin, and so on. The expression level of N-cadherin and the level of p-Akt/Akt decreased significantly (P0.05), and the effect of the above indexes in the combination group was better than that in the ginsenoside CK group and the 5-FU group (P0.05). Conclusion: both ginsenoside CK and 5-FU can inhibit the proliferation and induce apoptosis of PANC-1 cells, and the inhibition of EMT, may be related to the inhibition of phosphatidylinositol 3-kinase / Akt pathway.
