ABSTRACT

Objective:

To explore the Wnt-β-catenin signal molecule expression level in acute kidney injury rats renal tissue.

Methods:

A total of 48 rats accorded to the random number table method were divided into normal control group ( Control group) ,sham operation group ( Sham group) and ischemia reperfusion group ( IRI group) ,each group with 16 rats,Control group was given normal fed,IRI group were established ischemia reperfusion injury rats model,Sham group opened dorsal skin and then wound was closed. 4 rats were sacrificed respectively at 1,3,5,7 d after surgery,the pathological changes of kidney tissue were observed in the three groups,and the serum creatinine,urea level was detected in the three groups. Wnt4,β-catenin,Lrp6 protein expression was detected in three groups of rats by Western blot,Wnt4,β-catenin,Lrp6 mRNA in renal tissues were detected by Real-time quantitative RT-PCR.

Results:

There was no significant difference in renal injury score and serum creatinine between Control group and Sham group (P>0. 05),IRI group kidney injury score and serum creatinine,urea first increased and then gradually decreased,which was the highest in 3 d after surgery,IRI group renal injury score and serum creatinine,urea were significantly higher than those in Control group and Sham group 1,3,5,7 d after surgery (P0. 05),IRI group Wnt4,β-catenin,Lrp6 protein gradually increased,which reached to peak at 5 d after surgery,and then gradually decreased,IRI group Wnt4,β-catenin,Lrp6 protein were significantly higher than those in Control group and Sham group 1,3,5,7 d after surgery(P0. 05),IRI group Wnt4,β-catenin,Lrp6 mRNA gradually increased,which reached to peak at 3 d after surgery,and then gradually decreased,IRI group Wnt4,β-catenin,Lrp6 mRNA were significantly higher than those in Control group and Sham group 1,3,5,7 d after surgery (P<0. 05).

Conclusion:

The expression of Wnt-β-catenin signal molecule are significantly increase in acute kidney injury,and the activation of Wnt-β-catenin signal pathway is involved in the repair process of renal tissue.
