In the colon carcinoma Caco-2 cell line, which spontaneously differentiate into enterocyte-like cells in culture, FTH1P3 levels have been shown to increase threefold in fully differentiated enterocyte-like cells as compared to undifferentiated cells implying that FTH1P3 might be a marker for enterocyte differentiation27. This evidence concerns the gene FTH1P3 and colon carcinoma.
