Blocking oxidative stress and apoptosis of renal tubular epithelial could be a novel therapeutic target for diabetic nephropathy. Kaempferol (KMP), a natural phytoestrogen and common dietary flavonoid, has various biological effects including anti-oxidation, anti-apoptosis and anti-inflammation. KMP has protective effect against oxidative stress-related diseases, such as ischemia-reperfusion induced myocardium injuries, osteoporosis, obesity and so on.
