TFRC and colonic neoplasm: To further understand the effect of iron on TFRC in colon tumors, we utilized tissues from CDX2ERT2 ApcF/+ mice that were treated with 1.5% DSS and a high iron diet or an iron‐replete diet (40 mg kg−1 iron, 40Fe).[8] TFRC was significantly increased in colon tumors compared to normal colons from 40Fe treated mice (Figure S4C–S4E, Supporting Information).
