ID1 and cervical carcinoma: In this study, we demonstrated the relation of LMP1 (EBV) and E6 (HR-HPV) with poorly differentiated and invasive cervical SCCs as well as with the overexpression of the inhibitor of DNA binding 1 (Id-1) protein [88], which is associated with tumor formation and progression in different human malignancies, including cervical cancer [89,90].
