It was reported that in rats, secretin induces, via a cAMP-dependent pathway, exocytotic insertion of AQP1 in the apical membrane of cholangiocytes and facilitates the secretion of water into the biliary lumen (Tietz et al., 2003; Splinter et al., 2003).

The gapdh gene is frequently used as a reference gene because of its key role in the glycolytic pathway; however, gapdh is associated with several functions during evolution such as exocytotic membrane fusion, nuclear RNA export, DNA replication and repair, apoptosis, or viral pathogenesis (Bustin 2002, Huggett et al.

(90) Using inhibitors of clathrin-dependent endocytosis and ER-Golgi-dependent exocytotic protein translocation, we further demonstrated that the turnover of TRPA1 proteins in the plasma membrane is actively maintained to regulate TRPA1 activity in normoxia and hypoxia, and that the inhibition of PHDs by DMOG decelerates their internalization (Fig.
