Retinoic acid is reported here to induce peroxisomal beta-oxidation activities in cultured rat hepatocytes, with a concomitant increase in respective peroxisomal mRNAs. The concentrations of retinoic acid required for inducing liver peroxisomal acyl-CoA oxidase were similar to those required for inducing liver transglutaminase. A putative 5'-flanking response element for retinoic acid may be found within the enhancer region involved in the induction of peroxisomal genes by xenobiotic amphipathic carboxylates.
本文报道视黄酸可诱导培养的大鼠肝细胞中的过氧化物酶体β-氧化活性,同时相应的过氧化物酶体mRNA也会增加。诱导肝脏过氧化物酶体酰基辅酶A氧化酶所需的视黄酸浓度与诱导肝脏转谷氨酰胺酶所需的浓度相似。在异源生物双亲性羧酸盐诱导过氧化物酶体基因的增强子区域内可能存在一个假定的视黄酸5'-侧翼反应元件。
