Though there is limited information on microRNA (miRNA)-mediated regulation of HO-1 in PCa, miR-193a-5p lowers the expression of HO-1, facilitating docetaxel-related PCa cell apoptosis [86], Cheng et al. summarized the current literature on the role of microRNA in the post-transcriptional regulation of HO-1 expression indirectly through modulating the Nrf2/ARE pathway in different cancer types [87]. The gene discussed is HMOX1; the disease is cancer.
