MicroRNA‐214‐3p enhances erastin‐induced ferroptosis by targeting ATF4 in hepatoma cells

Primary liver cancer is the second most frequent cause of cancer‐related deaths. Ferroptosis, a recognized form of regulated cell death, recently gains attention. MicroRNA‐214‐3p (miR‐214) plays a regulatory role in hepatocarcinogenesis. However, the role of miR‐214 in cellular ferroptosis is unclear. This study aimed at elucidating whether miR‐214 could regulate ferroptosis of liver cancer. In vitro, HepG2 and Hep3B cancer cells were treated...
