Inhibition of USP1 ameliorates hypertensive nephropathy through regulating oxidative stress and ferroptosis: A precise treatment via SJB3-019A nanodelivery.

Hypertensive nephropathy is second only to diabetes for the causation of chronic kidney disease worldwide. As the mortality and morbidity of hypertensive nephropathy keep increasing, it is important to elucidate its pathogenesis and develop new treatment strategies. In this study, an angiotensin II (Ang II)-induced renal cell system was established, and the expression of ubiquitin specific peptidase 1 (USP1) in human kidney (HK-2) cells was found to be regulated by Ang II treatment through quantitative RT-PCR and Western blot assay.
