  • Multiple prior studies have identified aldehyde dehydrogenases (ALDH) that are capable of oxidizing retinal to retinoic acid. In this study, we test the hypothesis that the accumulation of intracellular retinoic acid may lead to the suppression of ALDH expression and thus increase cytotoxicity to 4-hydroperoxycyclophosphamide (4-HC) in vitro. Mainly A549, but also other lung cancer cell lines, were used in our experiments, with the former having high levels of two ALDH isozymes expressed. Dose… CONTINUE READING
