For example, circSCN8A in NSCLC and circLMO1 in cervical cancer were downregulated to inhibit the ACSL4‐mediated ferroptosis by sponging miR‐4192 and miR‐1290, respectively, facilitating the proliferation and metastasis of cancer cells.[153, 154] Additionally, it has been discovered that the upregulation of lncRNA CBSLR in gastric cancer plays a protective role in cancer cells against ferroptosis, resulting in drug resistance. This evidence concerns the gene ACSL4 and cancer.
