Abstract

Cell redox balance is crucially maintained by heme oxygenase 1 (HO-1) activity through its metabolicproducts which exert antioxidant, anti-apoptotic and anti-inflammatory effects. HO-1 up-regulation hasbeen correlated with the gain of resistance to therapy in different types of cancers and its involvementin cancer immune-escape has been hypothesized. In this work, we have investigated the involvementof HO-1 in BRAFV600E mutated melanoma cell resistance to Vemurafenib/PLX4032 (PLX) and inNatural Killer (NK)-dependent killing.
