Liang et al. [101] detected the expression of Gal-9 and E-cadherin in normal epithelium and endocervical glands, CIN, and cervical cancer tissues by immunohistochemical method and found that Gal-9 and E-cadherin were evidently detected in normal epithelium and endocervical glands, but those in CIN and SCC were significantly faint. This evidence concerns the gene LGALS9 and cervical squamous intraepithelial neoplasia.
