Abstract

Gastric Cancer is a common gastrointestinal malignancy worldwide, with a high mortality rate and poor prognosis. Multidrug resistance remains a major obstacle to successful treatment for patients. Hence, it is of great significance to develop novel therapies to potentiate the anti-tumor effect. In this study, we have investigated the effect of estradiol cypionate (ECP) on gastric Cancer in vitro and vivo. Our data show that ECP inhibited the proliferation, promoted Apoptosis, and caused G1/S phase arrest of gastric Cancer cells. The mechanism by which ECP promoted Apoptosis of gastric Cancer cells was related to the downregulation of Akt protein expression caused by the increased ubiquitination modification levels of Akt, which finally inhibited the over-activation of the PI3K-AKT-mTOR signaling pathway. In vivo tumorigenesis experiments showed that ECP significantly inhibited the growth of gastric Cancer cells, showing promise for clinical application. The above findings indicate that ECP inhibited the growth of gastric Cancer and induced Apoptosis through the PI3K /Akt/mTOR pathway. In summary, the efficacy showed in our data suggests that ECP is a promising anti-tumor compound for gastric Cancer.
