Purpose This study was performed to determine whether or not in cervical, ovarian and lung cancer cell lines, free radicals (ROS) play a role in cisplatin cytotoxicity and activation of the mitochondrial and JNK/p38 pathways. The role of the enzyme, dihydrodiol dehydrogenase (DDH1), in the activation/deactivation of this pathway and how this may be related to the development of resistance was also...
Dihydrodiol dehydrogenases are a family of aldo-keto reductases (AKR1Cs) involved in the metabolism of steroid hormones and xenobiotics. Herein, we have cloned and characterized the proximal promoter region of the human AKR1C1 gene. The 5′ flanking proximal promoter region of the AKR1C1 gene consists of a TATA box and an inverted CCAAT binding site. Deletion analysis of the 5′ flanking, ∼3.0kb region...
