简介
Dracorhodin perchlorate has been recently shown to induce apoptotic cell death in cancer cells. However, the molecular mechanisms underlying these effects are unknown in human gastric tumor cells. In this study, effects of Dracorhodin perchlorate on cell viability, cell cycle, and apoptosis were investigated in SGC-7901 cells. The results showed that Dracorhodin perchlorate induced cellular and DNA morphological changes and decreased the viability of SGC-7901 cells. Dracorhodin perchlorate-mediated cell cycle arrest was associated with a marked decrease in protein levels of phosphorylated retinoblastoma and E2F1. Dracorhodin perchlorate-induced apoptosis is mediated via upregulation of p53, inhibiting the activation of PI3K/Akt, and NF-κB, thereby decreasing the expression of the anti-apoptotic proteins, Bcl-2 and Bcl-XL. Interestingly, we also found that Dracorhodin perchlorate significantly …
