The Role of the Rho/ROCK Pathway in Ang II and TGF-β1-Induced Atrial Remodeling

Abstract

The increased expression of profibrotic factors (CTGF, ROCK1 and Smad2/3) played an important role in our RAP-induced AF model. Increased atrial profibrotic factors involve the activation of either the TGF-β1/RhoA/ROCK-1 or the TGF-β1/Smad2/3 signaling pathway.
