Figure S1. TRPV2 knockdown by siRNA. (A) MH-S cells were transfected with either green fluorescent protein (GFP) siRNA (control) or TRPV2 siRNA, and whole-cell extracts were prepared for Western blotting for TRPV2 and β-actin. (B) The bars represent mean + SE (n = 4–6) of TRPV2 protein levels relative to β-actin levels. Mean value of TRPV2 protein levels relative to β-actin levels in GFP siRNA lanes was set at 1.0. *p < 0.05. (PPTX 119 kb)
