Transcriptional activation of scavenger receptor expression in human smooth muscle cells requires AP-1/c-Jun and C/EBPbeta: both AP-1 binding and JNK activation are induced by phorbol esters and oxidative stress.

Abstract excerpt

Reactive oxygen species generated by treatment of smooth muscle cells (SMCs) with either phorbol 12-myristate 13-acetate or with the combination of H2O2 and vanadate strongly induce expression of the class A scavenger receptor (SR-A) gene. In the current studies, cis-acting elements in the proximal 245 bp of the SR-A promoter were shown to direct luciferase reporter expression in response to oxidative stress in...
