8. E7 is major transforming oncoprotein of human papillomavirus 16 and serves as paradigmatic example of intrinsically disordered proteins due to its N-terminal disordered domain. Data suggest mutation of leucines in N-terminal intrinsically disordered domain of E7 leads to pronounced increase in both alpha-helix and beta-sheet structures; thus, E7 appears to exhibit local structural elements that oppose canonical folding. PMID: 28952717
9. Authors observed thousands of unique HPV16 genomes; very few women shared the identical HPV16 sequence, however, E7 was devoid of variants in precancers/cancers compared to higher levels in the controls; this was confirmed in cancers from around the world.

14. the level of Cdc6 phosphorylation at serine 54 (S54P) was increased in E7-expressing cells. S54P was associated with an increase in the total amount of Cdc6 and chromatin-bound Cdc6. DNA damage-enhanced upregulation and chromatin binding of Cdc6 appeared to be due to downregulation of cyclin-dependent kinase 1 (Cdk1) as Cdk1 knockdown increased Cdc6 levels PMID: 27207654

22. Results found that HPV16 E7 increases RARB mRNA and protein expression both in vitro and in the cervix of young K14E7 transgenic mice suggesting that RARB overexpression is part of the early molecular events induced by the E7 oncoprotein. PMID: 26173416
23. E7 localised to the plasma membrane in cervical cancer cells. PMID: 26131956
24. findings suggest that increased IL-17A expression by macrophages in E7-expressing skin exposed to DNCB promotes arginase-1 induction and contributes directly to the observed hyperinflammation. PMID: 25720383
25. the modulation of HPV-16 E6/E7 expression remarkably influenced cell proliferation, migration, and invasion, as well as the protein levels of E-cadherin and P-cadherin in cervical cell lines. PMID: 26093522
26. The data showed that E7 induced CCNA1 methylation by forming a complex with Dnmt1 at the CCNA1 promoter, resulting in the subsequent reduction of expression in cancers. PMID: 26250467
