TFRC and neoplasm: Furthermore, using the 3F3-FMA antibody, which recognizes ferroptotic cells [34], we observed that IKE + DHAA induces a strong TfR signal in the tumor area (Fig. 5h), corroborating that IKE + DHAA favors the induction of ferroptosis in vivo, because Lpx treatment prevents 3F3-FMA immunoreactivity (Fig. 5h).
