ABSTRACT
Objective: To investigate the effect of Yangzheng Sanjie decoction on proliferation, apoptosis and extracellular signal-regulated kinase (ERK) pathway of human gastric cancer MKN-45 cells.Method: Gastric cancer cell line MKN-45 was treated for 24, 48, 72 h with Yangzheng Sanjie decoction (0.5, 1, 1.5, 2, 2.5, 3, 3.5 g·L-1); cell proliferation was measured by cell counting kit-8 (CCK-8); cell colony forming ability was observed by the plate cloning experiment after intervention with Yangzheng Sanjie decoction (0.4, 0.8 g·L-1); MKN-45 cells was treated with 4, 8 g·L-1, and then cell apoptosis was detected by flow cytometry; the expression of ERK and its phosphorylation level were detected by Western blot assay after treatment with 2, 4, 8 g·L-1.Result: Compared with the blank group, Yangzheng Sanjie decoction could significantly inhibit the proliferation of MKN-45 cells. After treatment for 24, 48 h, Yangzheng Sanjie decoction started from 2 g·L-1, and after treatment for 72 h, it started from 1.5 g·L-1, the cell viability gradually decreased in a concentration-dependent manner (PPP-1, cell colonies could not be formed; the apoptosis rate of Yangzheng Sanjie decoction was significantly higher than that of the blank group (PP-1, and the phosphorylation level of ERK protein in MKN-45 cells was down-regulated (PConclusion: Yangzheng Sanjie decoction can inhibit the proliferation of human gastric cancer cell line MKN-45 and promote its apoptosis. The mechanism may be related to the inhibition of phosphorylation of ERK.
