ACTA1 and congestive heart failure: Rats with CHF showed obvious pathophysiological changes including: altered renal hemodynamic parameters; dysregulated heart function; changes to serum concentrations of angiotensin II (AngII), cyclic guanosine monophosphate (cGMP), serum creatinine (Scr), blood urea nitrogen (BUN), C-reactive protein (CRP), brain natriuretic peptide (BNP); high serum and urine sCTGF concentration; high CTGF mRNA, CTGF, α-SMA and LRP expression in renal tissues; increased extracellular matrix (ECM) deposition and fibrosis in renal tissues.
