Connexin43 expression: (A) Western blotting of Cx43 and its respective densytometric analyses (B and C) showing total Cx43 expression increased in HTC-Cx43 when compared to HTC cells. Non-phosphorylated form (P0) was preferentially observed in BRL3A. While in HTC and HTC-Cx43 phosphorylated form (P1) was predominant. However in transfected cells (HTC-Cx43) there was increasing of the non-phosphorylated and phosphorylated forms (P0 and P2, respectively) when compared to HTC cells. (* p < 0.05).
