GJB5 and cervical cancer: Our results indicated that both GJB5 mRNA (Fig. 3D) and protein (Fig. 3E) levels were significantly elevated in primary human cervical cancer cells (priCC-1 and priCC-2) and immortalized cervical cancer cell lines (Caski and HeLa229) compared to primary cervical epithelial cells (priCEpi-1 and priCEpi-2).
