Several other factors, such as the apoptosis‐inducing factor alpha‐related 2 (AIFM2)‐Coenzyme Q10 (CoQ 10) pathway, the GTP cyclohydrolase‐1 (GCH1)‐tetrahydrobiopterin (BH4) pathway, the dihydroorotate dehydrogenase (DHODH)‐CoQH2 pathway and some tumour suppressors are also involved in the regulation of ferroptosis67, 68, 69 (Figure 2). Here, DHODH is linked to neoplasm.
