DDIT3 and neoplasm: The expression of DDIT3 was significantly induced in 14 organoids treated with 1 mg/mL of ferrichrome (A1, A2, A3, A4, A5, A7, A8, C1, C2, C3, C4, C7, C8, C9) (p < 0.05) and tended to be induced in the remaining 1 organoid (A6) (p = 0.0626), in which ferrichrome significantly inhibited the tumor growth in the MTT assay.
