Autophagy was decreased in the progression of renal fibrosis in diabetic nephropathy mice (in vivo) and in high glucose-induced NRK-52E cells (rat kidney epithelial cells) (in vitro) as the expression ofLC-3I and LC-3II (indicators of autophagy) were decreased mice MiR-142-5p was unregulated and PTEN was down-regulated in kidney mice and high glucose-induced NRK-52E cells.
Renal fibrosis in nephrectomized rats and profibrotic transforming growth factor-β-induced epithelial-mesenchymal transition (EMT) and ERK1/2 activation in NRK-52E cells were suppressed by sh-periostin.
These results suggest that liraglutide attenuates the EMT and ECM secretion of NRK-52E cells induced by TGF-β1 and EMT and renal fibrosis induced by UUO.
Our study illustrated that developed SMEDDS improved the oral absorption of emodin, and attained better suppressive effects on the protein level of renal fibrosis compositions in AGEs-induced GMCs and NRK-52E cells.
Herein, we investigated the effect of IMD on Nox4 expression and NADPH oxidase activity in rat UUO model, and explored if these effect were achieved through cAMP-PKA pathway, the important post-receptor signal transduction pathway of IMD, in TGF-β1-stimulated rat proximal tubular cell (NRK-52E).Renal fibrosis was induced by UUO.
Here, we compared the protective efficacies of miR-26a and miR-30c in renal tubular epithelial cells (NRK-52E) and determined whether they demonstrated additive effects in the attenuation of renal fibrosis.
