Overexpression of an miR-545-3p inhibitor or SLC7A11 rescued the inhibitory effect of silencing circ_0067934 on thyroid cancer cells and resulted in a decrease in the levels of ferroptosis-associated markers, such as Fe2+, iron, and ROS (Wang et al., 2021a). This evidence concerns the gene SLC7A11 and thyroid gland carcinoma.
