SGK2 helps reduce diabetic kidney damage by blocking cell death through NEDD4L-driven ACSL4 breakdown

Serum/glucocorticoid-regulated kinase 2 (SGK2) is predominantly expressed in renal proximal tubular cells.

• Progressive tubulointerstitial injury is a significant factor in the decline of renal function in diabetic kidney disease (DKD).
• Ferroptosis, a form of cell death, is associated with tubular injury in DKD but its molecular regulators are not fully understood.
• SGK2 may regulate ferroptosis, as indicated by its role in prostate cancer.
• The specific function of SGK2 in the context of DKD and tubular ferroptosis remains largely unexplored.
