3′-Hydroxypterostilbene down-regulated mTOR, PI3K/Akt and MAPKs signaling in COLO 205 cancer cells.

Abstract

<p>COLO 205 cells were treated with 50 µM 3′-hydroxypterostilbene at different times. Cell lyates were prepared and the protein levels of (A) p-mTOR, p-P70S6K, (B) p-PI3K, p-Akt and (C) p-ERK1/2, p-JNK1/2, p-p38 were analyzed by Western blotting analysis. All analyses were representative of at least three independent experiments. The values under each lane indicate relative density of the band normalized to β-actin using a densitometer.</p
