Abstract

Human phosphatase and tensin homolog (hPTEN) gene was expressed in vascular smooth muscle cells (VSMCs) to study its effect on VSMC proliferation induced in platelet-derived growth factor (PDGF) conditioned medium. After G418 selection, MTT assay was conducted to examine transfected VSMC proliferation induced in human PDGF conditioned medium. We successfully constructed eukaryotic expression vector pcDNA4/myc-His-PTEN and transferred into VSMC cells. We report that in vitro proliferation of VSMC was inhibited in PTEN transfected VSMCs induced in PDGF conditioned medium. RT-PCR and Western blot results indicated significantly high levels of protein kinase B-PKB and nuclear factor kappa B mRNA and protein, respectively, in PDGF group as compared with the control group.
