Fig. 10

HPV E7 upregulates expression of ABCC8, the gene encoding SUR1 which constitutes the regulatory subunit of KATP channels. Increased KATP channel activity contributes towards the activation of MAPK and AP-1 signalling. This, in turn, drives transcription from the viral URR and changes in host gene expression which together stimulate proliferation. Figure created using BioRENDER.com.
