S100A8 and cancer: Here, through establishing an 8q24 site-specific HPV18 gene knock-in cell model by utilizing the CRISPR/Cas9 system, we discover that HPV18 knock-in (HPV-KI) results in a global alteration of the genome’s topologically associating domain structure and an up-regulation of cancer-related genes in HPV- HaCaT cells, among which the significantly up-regulated IL-17 signaling pathway and S100A8/A9 are partitularly prominent.
