Angiotensin (ANG) II may induce CTGF expression in the heart and kidney and plays an important role in the pathogenesis of lung fibrosis.

Here we show that locally acting mIGF-1 increases SirT1 expression/activity, whereas circulating IGF-1 isoform does not affect it, in cultured HL-1 and neonatal cardiomyocytes. mIGF-1-induced SirT1 activity exerts protection against angiotensin II (Ang II)-triggered hypertrophy and against paraquat (PQ) and Ang II-induced oxidative stress.

On days 1, 3, 7, and 21 after paraquat treatment, TGF-beta1 and collagen gene expressions, TGF-beta1 protein, angiotensin-converting enzyme (ACE) activity, Ang II, and hydroxyproline contents were measured in lung tissue.

In the present study, we examined whether chymase and angiotensin converting enzyme (ACE), that also generates Ang II, were activated in the pulmonary inflammation and fibrosis induced by paraquat (PQ) in hamsters.

Angiotensin II (Ang II) inhibits the cardiac sarcolemmal Na (+)-K (+) pump via protein kinase (PK) C-dependent activation of NADPH oxidase.
We detected glutathionylation of beta (1), but not alpha (1), subunits in rabbit ventricular myocytes at baseline. beta (1) Subunit glutathionylation was increased by peroxynitrite (ONOO (-)), paraquat, or activation of NADPH oxidase by Ang II.

Furthermore, paraquat enhanced Ang II and collagen type I mRNA and protein expression, alpha-smooth muscle actin, and chymase protein and chymase small interfering RNA inhibited these effects.

The antifibrotic effect of lisinopril has shown to be due to inhibition of synthesis of angiotensin II that causes stimulation of fibroblast proliferation and collagen synthesis.
