Research Progress of Berberine in Kidney Disease: Targeting Mitochondria and Ferroptosis
iNew Medicine, EarlyView.This figure illustrates the model‐specific renoprotective mechanisms of berberine (BBR) across three major kidney diseases. From left to right, the diagram shows that BBR targets distinct core pathways depending on the pathological context: in diabetic nephropathy (DN), BBR activates AMPK to improve mitochondrial energy metabolism; in acute kidney ...
