SLC3A2 and hepatocellular carcinoma: Inhibition of miR-142-3p or overexpression of SLC3A2, an important protein involved in ferroptosis, reversed ferroptosis and inhibited the proliferation, and invasion of HCC cells indicating that miR-142-3p promoted the anti-tumorigenic M1-type macrophage ferroptosis through SLC3A2 [324].
