ACTR2 and cervical cancer: None of these proteins have been associated with cervical cancer in the literature, but the Human Proteome Atlas (HPA, http://www.proteinatlas.org accessed on 11 January 2021) [27] lists Prohibitin-2 as an unfavourable biomarker for endometrial cancer, Actin-related protein 2/3 complex subunit 5 as an unfavourable biomarker for both renal and liver cancer, Lysine-tRNA ligase as an unfavourable biomarker for head and neck cancer, and, finally, Testin as favourable biomarker for renal cancer and an unfavourable biomarker for pancreatic cancer.
