It was also reported that lysine (K)-specific demethylase 4A (KDM4A), which was highly expressed in cervical cancer tissue and could be induced under cobalt chloride mimicking hypoxia conditions, reduces the H3K9me3 level in the HIF-1α promoter region to elevate HIF-1α transcription, leading to the increased expression of TFRC and DMT1 via activating the HRE sequence in their promoters, and finally resulting in the increase in erastin-induced ferroptosis of cervical cancer cells [120]. Here, SLC11A2 is linked to cervical carcinoma.
