Hypoxia is a negative factor affecting CC treatment by inducing ferroptosis resistance. Our study aimed to investigate the detailed mechanisms of hypoxia-induced ferroptosis resistance in CC cells. The mRNA and protein levels were assessed using RT-qPCR and western blot. Immunofluorescence staining was used to analyze the co-localization of Budding uninhibited by benzimidazole 1 (BUB1) and Kinesin family member 20A (KIF20A) in CC cells.

MeRIP was adopted to measure the m<sup>5</sup>C level of KIF20A. We found that hypoxia facilitated ferroptosis resistance in CC cells. Hypoxia led to the upregulation of KIF20A, and KIF20A knockdown weakened hypoxia-mediated ferroptosis resistance in CC cells.

Rescue experiments indicated that BUB1 overexpression partially reversed the inhibitory effect of KIF20A knockdown on hypoxia-mediated ferroptosis resistance in CC cells.
