ABSTRACT
AIM:
We sought to evaluate the expression of apoptosis related genes, p53 and bcl-2, in cultured vascular smooth muscle cells (VSMCs) in which apoptosis was induced by the ligands of PPAR?-ox-LDL,ciglitazone and 15-deoxy-△ 12,14-PGJ 2,and then influenced by PGF 2?,an antagonist of PPAR?. To clarify whether PPAR? is involved in the regulations of p53 and bcl-2.METHODS:
Rat aorta smooth muscle cells were isolated and cultured in DMEM containing 10%FBS. ox-LDL,ciglitazone and 15 d-PGJ 2 were added into the medium for 24 h, respectively. Using PGF 2? to inhibit PPAR? activation via activation of MAP kinase. We employed the flow cytometry analysis to quantitatively analyze the apoptosis of VSMCs. Also, we measured and analyzed the discrepancies of the expression of p53 and bcl-2 between every groups.RESULTS:
During the process of apoptosis induced by PPAR?,the expression of P53 protein increased (P
