Abstract: Objective To evaluate the effect of ulinastatin on hypoxia-induced phenotype modulation of pulmonary artery smooth muscle cells (PASMCs) and explore the underlying mechanism. Method Cultured PASMCs from SD rats were exposed to normoxic condition, normoxia with ulinastatin treatment, hypoxia, or hypoxia with ulinastatin treatment. After 24 h of exposures, the cells were examined for SM-α-actin and caplonin expressions with immunofluorescence assay and for cell migration with CCK-8 and 3H-TdR assays. Western blotting was used for detecting the expressions of PPAR-γ in the cells, and PPAR-γ-responsive firefly luciferase reporter was employed for measuring the transcriptional activity of PPAR-γ. The PPAR-γ inhibitor GW9662 was used to explore the mechanism of the inhibitory effect of ulinastatin on hypoxia induced-phenotype modulation of PASMCs by measuring the changes in cell proliferation and migration. Results Ulinastatin obviously enhanced the expressions of SM-α-actin and calponin (P<0.05), inhibited the proliferation and migration (P<0.05), and up-regulated the expression of PPAR-γ in PASMCs exposed to hypoxia (P<0.05). Pretreatment of the cells with GW9662 abolished the effect of ulinastatin on hypoxia-induced phenotype modulation of PASMCs and enhanced the cell proliferation and migration (P<0.05). Conclusion Ulinastatin inhibits hypoxia-induced phenotype modulation of PASMCs from rats possibly by up-regulating the expression of PPAR-γ.
