ABSTRACT
Objective To observe the expression of cysteine rich-protein 61 (Cyr61) on renal tubular cells,to explore its effects against hypoxic induced kidney injury and the underlying mechanisms.Methods A stably Cyr61 expressed tubular cell line Cyr61-HK2 was established based on HK2 cells and recombinant Cyr61-lentivirus.BrdU incorporation assay was used for cell proliferation.The apoptosis of cells was analyzed by flow cytometry with Annexin V and propidiumiodide staining.Western bloting was used to detect the protein expression of BAD,Akt and ERK.Results (1) Cyr61-HK2 cells displayed more proliferation ability than HK2 cells.(2) Under hypoxia condition,the apoptosis of both HK2 and Cyr61-HK2 cells increased,but the apoptosis of Cyr61-HK2 cells was lesser than HK2 cells.(3) The expression of Cyr61 led to the phosphorylation of BAD,Akt and ERK on 0 h,0.5 h,1 h (all P < 0.05).Conclusion The expression of Cyr61 can promote cell proliferation and dampen cell apoptosis induced by hypoxia,which may be involved in the Akt/ERK signal pathway.
