SLC5A3 and cervical cancer: SLC5A3 mRNA and protein expression was significantly upregulated in the primary human cervical cancer cells (pCCa-1/-2/-3 cells, which were obtained from Dr. Cao 18) and the immortalized HeLa cells (Figure 2D-F), but were low in the cervical epithelial cells (HCerEpC1 18 and Ect1/E6E7 cells) (Figure 2D-F).
