Podocarpusflavone alleviated renal fibrosis in obstructive nephropathy by inhibiting Fyn/Stat3 signaling pathway.

Tubulointerstitial fibrosis is a common pathological change in end-stage renal disease. However, limited treatment methods are developed, and unexplained potential mechanisms of renal diseases are urgent problems to be solved. In the present research, we first elucidated the role of podocarpusflavone (POD), a biflavone compound, in unilateral ureteral obstruction (UUO) in rodent model which is characterized by inflammation and fibrosis.

Formononetin ameliorates ferroptosis-associated fibrosis in renal tubular epithelial cells and in mice with chronic kidney disease by suppressing the Smad3/ATF3/SLC7A11 signaling.

Aims: Chronic kidney disease (CKD) is characterized by interstitial fibrosis, while limited treatment drugs are available. Ferroptosis is a newly identified process that can trigger tubular atrophy and fibrosis. The aim of this study is to investigate the effects of formononetin (FN), a bioflavonoid, on ferroptosis and renal fibrosis.

The Smad3-dependent microRNA let-7i-5p promoted renal fibrosis in mice with unilateral ureteral obstruction.

Renal fibrosis is a common feature of all types of chronic kidney disease (CKD) and is tightly regulated by the TGF-β/Smad3 pathway. Let-7i-5p belongs to the let-7 microRNA family with diverse biological functions. It has been reported that let-7i-5p suppresses fibrotic disease in the heart, lungs, and blood vessels, while the role of let-7i-5p in renal fibrosis remains limited.
