FBXW7 mediates high glucose‑induced SREBP‑1 expression in renal tubular cells of diabetic nephropathy under PI3K/Akt pathway regulation.

ABSTRACT: Diabetic nephropathy (DN) is a severe complication of diabetes mellitus and lipid metabolism abnormality serves a key role in the pathogenesis of DN. Sterol regulatory element‑binding protein 1 (SREBP‑1) overexpression mediates aberrant lipid accumulation in renal tubular cells of DN. However, the exact mechanism involved in increased SREBP‑1 has not been fully elucidated. The aim of the present study was to explore the mechanism involved in SREBP‑1 upregulation. Diabetic mice and high glucose‑cultured HKC cells were chosen to detect the expression of FBXW7 and SREBP‑1 using immunohistochemistry, western blotting and PCR. The present study demonstrated that F‑box and WD repeat domain containing 7 (FBXW7) expression was decreased in renal tubular cells of diabetic mice. Moreover, the co‑exp
