Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Abstract

Background: Integration of human papillomavirus (HPV) DNA into human genome is the reputed key driver of cervical cancer. However, the effects of HPV integration on chromatin structural organization and gene expression are largely unknown in such cancer.

Methods: We investigated a cohort of 61 samples for HPV integration analysis. And selected a fresh cancer tissue from the set of clinical samples whose tissue only contained unique integration loci at CCDC106 and contained no HPV episomal DNA. A combination of WGS, RNA-seq, ChIP-seq and Hi-C data analysis were applied to identify the mechanisms of HPV integration in cervical carcinogenesis. IHC staining was used to validate the expression change after HPV-CCDC106 integration.

Results: Based on the cohort of 61 samples, we identified a hot integrated site in the CCDC106 gene on chromosome 19. Additional analysis showed that this chromosome was enriched with genome variation and differential expression densities in the same HPV-CCDC106 integrated carcinoma sample. More importantly, we identified that HPV divided one topologically associated domain (TAD) into two TADs and hijacked an enhancer from PEG3 to CCDC106, thus leading to a decrease in PEG3 expression and high CCDC106 expression. This expression dysregulation was further confirmed by 10 samples exhibiting the same HPV-CCDC106 integration from our cohort.

Interpretation: We found that HPV-CCDC106 integration tended to alter the architecture of the local chromosome and hijacked an enhancer via 3D genome structure remodeling, thus providing insight into the 3D structural mechanism underlying HPV integration in cervical carcinogenesis.
