Aldose reductase inhibitor, fidarestat regulates mitochondrial biogenesis via Nrf2/HO1/AMPK pathway in colon cancer cells

Although we have shown earlier that aldose reductase (AR) inhibitors prevent colorectal cancer cell (CRC) growth in culture as well as in nude mice xenografts, the mechanism(s) is not well understood. In this study, we have investigated how AR inhibition prevents CRC growth by regulating the mitochondrial biogenesis via Nrf2/HO-1pathway. Incubation of CRC cells such as SW-480, HT29, and HCT116 with AR inhibitor, fidarestat that non-covalently binds to the enzyme, increases the expression of Nrf2.
