Increased endothelin receptor B and G protein coupled kinase-2 in the mesentery of portal hypertensive rats

Figure 3 Western blots of endothelin A receptor (A), endothelin B receptor (B), G protein coupled kinase-2 (C) and β-arrestin 2 (D) in rat mesentery. Expression of the investigated proteins in mesentery from sham-operated rats and mesentery from common bile duct ligation (CBDL) rats was compared by Western blot. Representative Western blots are shown for each protein and densitometric quantification of all experiments are provided (data are mean ± SE; n = 3-6/group). ^aP < 0.05, ^bP < 0.01 for CBDL rats vs sham-operated rats. ETAR: Endothelin A receptor; ETBR: Endothelin B receptor; GRK2: G protein coupled kinase-2; D.U.: Densitometric units.
