ABSTRACT
Objective To observe the effect of daidzein on extracellular matrix of uremic rats and to discuss its mechanism.Methods Uremic rat model were established by 5/6 nephrectomized. Model rats were devided into daidzein group, control group. Rats with sham-operation were regarded as the normal control. At time of baseline, 4th and 8th week after operation, urinary protein and biochemical detection were measured. The pathologic changes, fibronectin (FN) and typeⅣcollagen (ColⅣ) were investigated at 8th week. The Western-Blot and RT-PCR were used to measure protein expression and mRNA transcription of TGF-β1. Results At 8th week after operation, the urinary protein (12.35 ± 2.13 mg/24 hvs. 19.93 ± 3.19 mg/24 h), serum urea (10.11 ± 0.65 mmol/Lvs.12.09 ± 0.78 mmol/L) and creatinine (68.10 ± 2.51μmol/Lvs.77.63 ± 3.20μmol/L) in the daidzein group decreased significantly than those in the control group (P<0.01). The deposition of ColⅣ (16.33% ± 2.14%vs. 24.68% ± 3.97%) and FN (19.17 ± 2.68 vs. 29.35 ± 4.15) in the daidzein group decreased significantly than those in the control group (P<0.01). Compared with control group, the pathological lesion in the daidzein group was less serious. The mRNA transcription (0.37 ± 0.06vs. 0.64 ± 0.08) and protein expression of TGF-β1 (0.28 ± 0.09vs. 1.40 ± 0.13) in the daidzein group were attenuated significantly than those in the control group (P<0.05). ConclusionsDaidzein had a beneficial effect on uremic rats. It may be associated with a decrease of extracellular matrix accumulation.
