Abstract

Objective

To explore the mechanism of KLF15 on the biological activity and autophagy of gastric cancer cells based on the PI3K/Akt/mTOR signaling pathway.

Methods

The gastric cancer AGS cells were divided into the Con group, pcDNA-NC group, pcDNA-KLF15 group, LY294002 group and IGF-1 group. RT-PCR was used to detect the expression of KLF15 in human gastric mucosal cells and gastric cancer cells; MTT method to detect cell proliferation; Transwell method to detect cell invasion; flow cytometry to detect cell apoptosis; Western blotting to detect PI3K, Akt, mTOR in cells, LC3, Beclin1, p62 protein expression. 0.05 was used to indicate statistical significance.

Results

Compared with the human gastric mucosal cell line GES-1 cells, the expression of KLF15 in human gastric cancer cell lines MKN-28, MFC, SCG-7901 and AGS cells was significantly decreased, And the expression of KLF15 in AGS cells, was the lowest (0.006). Compared with the Con group, The expression of KLF15 in the cells of the PCDNA-KLF15 group was significantly increased (0.018); There was no significant difference in the expression of KLF15 between the Con group and the PCDNA-NC group (0.225). Compared with the Con group, the proliferation and invasion abilities of the cells in the pcDNA-KLF15 group were significantly reduced, And the apoptosis ability was significantly increased (0.019). The ratio of LC3II/LC31 and the expression of Beclin1 Protein in the control group were significantly higher than those in the Con group (0.017).

Conclusion

Overexpression of KLF15 can inhibit the proliferation and invasion of Gastric cancer cells and promote cell apoptosis and autophagy, and its mechanism may be related to the regulation of the PI3K/Akt/mTOR signaling pathway.
