Galectin-9, which is encoded by LGALS9, is evidently detected in normal epithelium and endocervical glands but not in cervical intraepithelial neoplasia and cervical squamous cell carcinoma, which indicates that decreased Galectin-9 is a biomarker for the malignant potential of cervical cancer (Liang et al., 2008). Here, LGALS9 is linked to cervical cancer.
