Additional file 3. Figure S2. GPCR has not affected YAP expression in colon cancer cells. A Subtypes of GPCR in SW480 and SW1116 cells were knocked down by transfecting small interfering RNAs; a western blot was used to analyse YAP and Cyr61 expression in cells treated with 10 μM 5-HT. **, P < 0.01. B Hela cells were stimulated with 10 μM 5-HT after transfection with hSERT pcDNA3 vector, and YAP expression was analysed by western blot
