title: [Effect of oxidatively modified high density lipoprotein on transcriptional expression of proto c-fos and PDGF receptor genes in cultured human arterial smooth muscle cell].
abstract: The proliferation of arterial smooth muscle cell (SMC) plays an important role in the process of atherosclero-genesis. Using the establishment of primary culture and sub-culture method for human arterial SMC, we observed the effects of native HDL (N-HDL) and oxidized HDL of proto c-fos and PDGF receptor genes transcriptional expression in cultured SMC. The results showed that N-HDL had no effect on the expression of proto c-fos and PDGF receptor genes in the cultured human SMC, that OX-HDL had no effect on the expression of PDGF receptor gene in the cultured human SMC, and that OX-HDL promoted the expression of protoc-fos gene significantly (P < 0.01). These results suggest that the OX-HDL's atherogenic role is closely related to its stimulating effect on proto c-fos gene expression of SMC.
