For example, Peng Wu 85 showed that circEPSTI1 promoted the proliferation of cervical cancer via miR-375/409-3P/515-5p acting as a ceRNA by targeting SLC7A11 and attenuated the effect of lipid peroxidation and GSH/GSSG to inhibit ferroptosis of cervical cancer cells. The gene discussed is SLC7A11; the disease is cervical carcinoma.
