ABSTRACT
Objective To observe the expression of bone morphogenetic protein 7 (BMP-7) in different stages of diabetic rats and investigate the potential role of BMP-7 in diabetic nephropathy (DN). Methods Wistar rats were divided into diabetes mellitus(DM) group induced by intravenous injection of streptozotocin (65 mg/kg) , and normal control group injected with citrate buffer. The rats were sacrificed at day 30,60,90,120,150 and 180 following injection, respectively. The blood glucose,Scr, urinary albumin and urinary creatinine were measured in each rat before sacrifice. The renal pathological changes were examined with hematoxylin and eosin (HE),periodic acid-silver-methenamine staining (PASM) and protein expression of collagenⅣ(ColⅣ). The mRNA and protein expression of BMP-7 and TGF-?1 in kidney were detected by reverse transcription-polymerase chain reaction (RT-RCR) and immunohistochemical staining respectively, and were quantified by computer image analysis system. Results The levels of blood glucose and urinary albumin in diabetic group were remarkably higher than those in control group (P
