Pathways unique for this subset are “human papillomavirus infection” (included genes: COL1A1, COL3A1, COL1A2, ACTN1, LAMB1) and “regulation of actin cytoskeleton” (included genes: ITGA10, MYLK, ACTN1, MYH10, PDGFRB, MYL9, ENAH, ITGA11, ITGB5). This evidence concerns the gene PDGFRB and human papilloma virus infection.
