Effects of black rice anthocyanins (BRACs) or Y15 on the phosphorylation of focal adhesion kinase (FAK), cSrc, and p130Cas and the interaction among these proteins. (A) Cells treated with/without BRACs were harvested for the detection of the phosphorylation of FAK, and cSrc, p130Cas using western blot analysis. The expression of actin was used as a loading control. (B) Cells treated with/without BRACs were harvested for detecting the interaction between human epidermal growth factor receptor-2 (HER-2) and FAK by immunoprecipitation. The expression of HER-2 was used as a loading control. (C) The interaction among FAK, cSrc and p130Cas. The expression of cSrc was used as a loading control. (D) The interaction between FAK and p130Cas. The expression of p130Cas was used as a loading control. (E) Cells treated with/without Y15 were harvested for detecting the phosphorylation of FAK, cSrc, and p130Cas using western blot analysis. The expression of actin was used as a loading control.
