Abstract
BACKGROUND/AIM
This study aimed to assess the effects of telmisartan (TEL), a potential antitumor agent, and its mechanism of action in the regulation of apoptosis, autophagy, and cell cycle in scirrhous gastric cancer (SGC).
MATERIALS AND METHODS
The effect of TEL on the viability and chromatin condensation of OCUM-2M and OCUM-12 cells was assessed. Protein expression and the cell cycle were analysed using western blotting and flow cytometry, respectively.
RESULTS
TEL inhibited cell proliferation in a dose-dependent manner and increased chromatin condensation and autophagy marker LC3-II levels in OCUM-12 cells. TEL also increased the proportion of cells in the G0/G1 phase transition.
CONCLUSION
Apoptosis and autophagy are partially involved in the inhibitory effect of TEL on cell proliferation. Additionally, TEL caused G0/G1 cell cycle arrest. Therefore, TEL could be a promising treatment for SGC.
