CYB5D2 is a novel tumor suppressor by suppressing cervical cancer tumorigenesis.
CYB5D2 inhibits HeLa cell invasion in vitro and lung metastasis in vivo.
CYB5D2 is reduced in 85% of primary squamous cell carcinomas of the cervix.
CYB5D2 suppresses cervical cancer independently of its association with heme.
