Butyrate reduces diabetic glomerular injury through GPR109A. Butyrate treatment in GPR109A−/− diabetic mice did not alter kidney to body weight ratio (A) but resulted in less glomerular hypertrophy (B) and glomerular hypercellularity (C) compared to WT diabetic controls. Increased interstitial collagen deposition was partially attenuated by butyrate treatment in GPR109A−/− diabetic mice (D, F).
