Key result
Valsartan significantly inhibited cell proliferation and down-regulated mRNA and protein expression of angiotensin II type 1 receptor in cultured rat mesangial cells compared to control (p<0.01).
Why the study?
Angiotensin II type 1 receptor activation is associated with glomerular injury and disease, prompting investigation into the effect of valsartan on its expression in cultured rat mesangial cells.
p-value: p=<0.01
Angiotensin II type 1 receptor activation has been shown to be associated with glomerular injury and glomerular disease. Therefore, the present study aims to investigate the effect of the angiotensin II type 1 receptor antagonist valsartan on angiotensin II type 1 receptor expression in cultured rat mesangial cells. Sprague-Dawley rat mesangial cell lines obtained from China Center for Type Culture Collection were used in the study. The viability of rat mesangial cells was assessed by 3-(4,5-dimethylthiazol-2-yl)- 2,5-diphenyltetrazolium bromide. The results showed that valsartan inhibited cell proliferation and downregulated messenger ribonucleic acid and protein expression of angiotensin II type 1 receptor in rat mesangial cells. These levels were significantly lower than control group (p<0.01). Because angiotensin II type 1 receptor has a central role in the development and progression of glomerular diseases. Valsartan down-regulation of angiotensin II type 1 receptor expression of mesangial cells may provide beneficial effects to the glomerular injury. These data will be beneficial for understanding the mechanism of valsartan on the glomerular protection.

Li et al. (2022) studied Glomerular injury. Valsartan vs. Control (solvent/methanol solution) was evaluated on Cell proliferation and AT1R mRNA/protein expression (p=<0.01). Valsartan significantly inhibited cell proliferation and down-regulated mRNA and protein expression of angiotensin II type 1 receptor in cultured rat mesangial cells compared to control (p<0.01).
