We found no significant difference in the expression of Kir6.1 (KCNJ8), whilst Kir6.2 (KCNJ11) expression was higher in HPV-negative (HPV-) C33A cells, as well as three of the four HPV+ cervical cancer cell lines, when compared with normal human keratinocytes (NHKs) (Fig. 2A). Here, KCNJ11 is linked to cervical carcinoma.
