Abstract
Accumulating studies confirmed that luteolin, a common dietary flavonoid which is widely distributed in plants and has diverse beneficial biological function, including anti-oxidant, anti-inflammation and anticancer properties. However, the detail mechanisms of luteolin on GC are poorly understood. Here, we investigated the anticancer effect of luteolin in GC cells in vitro and in vivo. Luteolin reduced the cell viability in a time and dose-dependent manner. Luteolin significantly inhibited cell cycle progress, colony formation, proliferation, migration, invasion and promoted apoptosis in vitro and in vivo. Luteolin also regulated these biological effects associated regulators. Mechanically, luteolin treatment regulated Notch1, PI3K, AKT, mTOR, ERK, STAT3 and P38 signaling pathways and modulated a series of miRNAs expression. These findings provide novel insight into the molecular function of luteolin which suggest its potential as a therapeutic agent for human GC.
