Table 2 The role of ferroptosis in colorectal cancer

Intervention	Target	Effects and mechanism	Ref.
SRSF9	GPX4↓	Inhibition of SRSF9 increases erastin-induced iron death by downregulation of GPX4 level	[74]
IMCA	SLC7A11↓	IMCA induces SLC7A11 mediated ferroptosis through AMPK/mTOR pathway	[77]
TalaA	ROS↑, SLC7A11↓	TalaA induces ferroptosis to kill CRC cells	[144]
Lipocalin 2	GPX4↑, system Xc−↑	Overexpression of Lipocalin 2 inhibits ferroptosis and promotes CRC progression	[75]
TIGAR	GSH↓, ROS↑	TIGAR induces ferroptosis resistance in CRC by ROS/AMPK/SCD1 signaling pathway	[145]
HIF-2α	Iron↑	HIF-2α activation potentiates oxidative cell death in CRCs by increasing cellular iron	[79]
TP53	Lipid peroxidation, ACSL4↑	Restricts ferroptosis by blocking DPP4 activity in a transcription independent manner TP53	[91]
Tagitinin C	NRF2/HO-1↑, lipid peroxidation	Tagitin C activates NRF2/HO-1 pathway to induce ferroptosis	[82]
Cetuximab	NRF2↓, ROS↑	Cetuximab inhibits Nrf2/HO-1 pathway to promote ferroptosis in CRC	[85]
