TGFB1 and renal fibrosis: Zhang et al. [79] investigated the mechanism of action of antioxidant peptide (YWDHNNPQIR) extracted from rapeseed to alleviate renal fibrosis in diabetic nephropathy and found that it was able to significantly inhibit the expression of p65 in diabetic mice, and at the same time, it had a significant inhibitory effect on the high glucose-induced phosphorylation of p65 and transforming growth factor beta 1 (TGF-β1) in the glomerular thylakoid membrane cells of rats.
