title: Pristane induced gene activation.
abstract: Studies were performed to examine the effects of 2,6,10,14-tetramethyl pentadecane (pristane) versus 12-O-tetradecanoylphorbol 13-acetate (TPA) on the activation of the CAT gene under the regulatory control of viral promoter/enhancer elements transfected into NIH-3T3, CV-1 and COS-7 cells. The results of these studies demonstrated that (1) pristane or TPA induced trans-activation of SV2cat, HIVcat, RSVcat and MMTVcat in cells transfected with each respective plasmid construct, (2) only pristane induced activation of pA10cat and pOSP/11 and (3) neither TPA nor pristane trans-activated pSV0cat. Furthermore, treatment with either pristane or TPA elicited changes in the morphology of each of the cell lines. Collectively these results indicate that pristane is a potent inducer of gene expression and exhibits similar characteristics as the tumor promoter, TPA.
