CA9 and cervical squamous intraepithelial neoplasia: These findings are related to results previously found in our laboratory, where high expression of enzymes and transporters involved in glycolytic metabolism such as SLC2A1 (GLUT1), LDHA, SLC16A3 (MCT4), CA9 (CAIX), and BSG (Basigin or CD147) were found to be associated with the grade of cervical intraepithelial neoplasia (CIN), invasive cervical carcinoma (ICC), and HPV 16 infection [82,107].
