Effects of exosome/TRPP2 siRNA complexes on TRPP2 expression levels in FaDu cells. (A) Western blotting images and (B) summary data displaying TRPP2 expression levels in FaDu cells transfected with scrambled (Con) or TRPP2 (Exo) siRNA. The optical density of each protein was normalized to GAPDH. Values are presented as the mean ± standard error of the mean (n=3). *P<0.05 vs. control. siRNA, small interfering RNA; TRPP2, transient receptor potential polycystic 2; Exo, exosome; Con, control.
