Abstract
Peroxisome proliferators (PPs) are non-genotoxic carcinogens in rodent s, They can induce the expression of numerous genes via the heterodime rization of two members of the steroid hormone receptor superfamily, c alled the peroxisome proliferator-activated receptor (PPAR) and the 9- cis retinoic acid receptor (RXR). Many of the PP responsive genes poss ess a peroxisome proliferator response element (PPRE) formed by two TG ACCT-related motifs. The bifunctional enzyme (HD) PPRE contains 3 such motifs, creating DR1 and DR2 sequences. PPAR and RXR regulate transcr iption via the DR1 element while DR2 modulates the expression of the g ene via auxiliary factors in HepG2 cells.
