Solasodine inhibits human colorectal cancer cells via suppression of AKT/GSK-3β/β-catenin pathway

Summary

Solasodine is a main active component isolated from Solanum incanum L, who performs a wide range of functions containing anti-oxidant, anti-infection and neurogenesis promotion. In this study, we explored the influence of solasodine on three types of human colorectal cancer (CRC) cell lines. The consequences displayed that solasodine apparently prohibited CRC cell proliferation dose- and time-dependently and impeded CRC cell motility by downregulating Matrix metalloprotease (MMPs). Besides, solasodine was investigated to fuel caspase-cascade reaction and increase the ratio between Bax and Bcl-2 so as to induce CRC cell apoptosis. When cells got pretreated with AKT activator (IGF-1) followed by solasodine application, solasodine-induced apoptosis was partially confronted by IGF-1. Moreover, Solasodine hindered tumor development and stimulated similar mechanisms in vivo. In general, our study provides the first evidence that solasodine has a suppressive efficient on CRC cells and that this agent may have potency to be a novel therapeutic drug for CRC treatment.
