Astragaloside IV attenuates fatty acid-induced renal tubular injury in diabetic kidney disease by inhibiting fatty acid transporter protein-2

Renal tubular injury induced by free fatty acid bound to albumin is the key pathological basis for the progression of diabetic kidney disease. However, effective interventions are limited. Astragaloside IV, as a major bioactive component purified from Astragalus membranaceus (Fisch.) Bunge, possesses pharmacological properties of lowering blood glucose and proteinuria, and renal tubular protection in diabetic kidney disease. Further work is needed to understand the underlying molecular mechanisms.
