A potential avenue to overcome the targeting of antigens on solid tumors that are also present on normal tissues is the targeting of tumor-restricted post-translational modifications such as solid tumor overexpressed truncated O-glycans such as Tn (GalNAca1-O-Ser/Thr) and sialyl-Tn (STn) (NeuAca2–6-GalNAca1-O-Ser/Thr)54. This evidence concerns the gene EEF1A2 and neoplasm.
