Exact excerpt

Clinical validation revealed that SRPX2 expression was significantly elevated in kidney biopsy tissues and serum samples of CKD patients with various renal pathological types... In two classic mouse renal fibrosis models of unilateral ureteral obstruction (UUO) and folic acid (FA)-induced nephropathy, as well as in TGF-β1-stimulated human renal tubular epithelial HK-2 cells, SRPX2 was significantly upregulated... Global and TEC-specific ablation of Srpx2 was sufficient to attenuate kidney injury and fibrosis. Mechanistically, SRPX2 physically interacted with iron regulatory protein 1 (IRP1)... ultimately triggering intracellular iron dyshomeostasis. Notably, therapeutic iron dextran supplementation alleviated UUO-induced renal fibrosis.
