CA9 and cervical cancer: On the other hand, the expression observed in the Ca Ski and C-33A cell lines was similar to that observed in the 306 CC samples and the 13 normal tissue samples reported in the TCGA dataset, in which the expression of the six genes evaluated was found to be increased with statistically significant differences in SLC2A1, LDHA, CA9, and SLC16A3 (Figure 1), as in primary advanced uterine cervical carcinoma [35], human-papilloma-virus-type-16-positive and negative cervical cancer, [37] and cervical cancer [42].
