Platelet-derived growth factor gene expression in cultured human retinal pigment epithelial cells

Biochem Biophys Res Commun. 1992 Nov 30;189(1):66-71. doi: 10.1016/0006-291x(92)91526-v.

Abstract

Gene expression of platelet-derived growth factor (PDGF) and its receptors in cultured human retinal pigment epithelial (RPE) cells was studied by using semiquantitative polymerase chain reaction. The RPE cells were found to express PDGF A- and B-chain genes as well as alpha- and beta-receptor genes with dominant expression of B-chain and beta-receptor isoforms. Phorbol myristate acetate (PMA) and thrombin increased the expression of PDGF B-chain gene to 19.8 +/- 1.75 and 15.9 +/- 1.84 fold (n = 3) of the control without affecting beta-receptor gene expression. PDGF produced by the RPE cells may play an important role in the pathogenesis of some ocular proliferative diseases.
