NBR2 knockdown compromised curcumin-induced changes in protein phosphorylation in AMPK/mTOR signaling. A and B, Western blotting bands and quantitative analysis showed phosphorylation of AMPK, ACC, S6K, and S6 proteins in curcumin-treated HCT116 cells with shNBR2 transfection and treated with 0 or 10 μM curcumin for 24 hours. C and D, Phosphorylation of AMPK, ACC, S6K, and S6 proteins in curcumin-treated SW480 cells with shNBR2 transfection and treated with 0 or 10 μM curcumin for 24 hours. Three independent experiments were performed, and the results are presented as the mean ± standard deviation. AMPK indicates adenosine monophosphate-activated protein kinase.
