Objective:To study the effect of Ulinastatin on ENaC-α mRNA and protein of human alveolar epithelial A549 cells which are treated with hypoxia.Methods:A549 cells were divided into two groups
hypoxia group and ulinastatin group.A549 cells were treated with Ulinastatin at the doses of 1 250
2 500 U/ml and 5 000 U/ml for 48 h when cotreated with 3% O2 or 0% O2.The mRNA and protein levels of ENaC-α were determined by semiquantitative RT-PCR and Western blot.Results:Incubation of A549 with 1 250 U/ml
2 500 U/ml and 5 000 U/ml of Ulinastatin for 48 h could significantly upregulate the expression of ENaC-α in a concentration-dependent manner.Conclusion:Ulinastatin could reverse the inhibitory effect of hypoxia on the expression of ENaC-α
which suggests that ulinastatin can promote lung fluid clearance and pulmonary edema reduction.
