NCOA4 and gastric cancer: As shown in Figure 6, TGF-β1 slightly increased the level of ferritin compared to control (Figures 6(g) and 6(c)); however, the addition of DpdtC significantly attenuated the action of TGF-β1 on ferritin modulation (Figure 6(k)), leading to marked increase of NCOA4, indicating that DpdtC still induced ferritinophagy in gastric cancer cells even the cells were undergoing EMT.
