CircRNA circSTIL inhibits ferroptosis in colorectal cancer via miR‐431/SLC7A11 axis [29].CircRNA1615 inhibits ferroptosis via modulation of autophagy by the miRNA152-3p/LRP6 Axis in Cardiomyocytes of Myocardial Infarction [30].Circular RNA circBLNK promotes osteosarcoma progression and inhibits ferroptosis in osteosarcoma cells by sponging miR-188-3p and regulating GPX4 expression [11]. The gene discussed is SLC7A11; the disease is osteosarcoma.
