SLC7A11 and oral cavity squamous cell carcinoma: Whereas circPDE3B indirectly inhibits ferroptosis and promotes ESCC development through the HNRNPK/SLC7A11 and miR-516b-5p/CBS axis55; circ_000014/miR-527 reduces the sensitivity of oral squamous cell carcinoma cells to ferroptosis and increases their resistance to cisplatin (DDP) by regulating SLC7A11 expression.56
