E6 has several functions contributing to tumorigenesis one of which is blocking programmed cell death, apoptosis. The detailed mechanism of anti-apoptosis function of E6 is not fully understood. Here, using a <em>Drosophila</em> model of HPV18E6 and the human UBE3A-induced pathogenesis, we show that anti-apoptotic function of E6 is conserved in <em>Drosophila</em>. We demonstrate that the <em>Drosophila</em> homologs of human NF-κB transcription factors, Dorsal and Dif are proapoptotic. They induce the expression of Wingless (Wg, the <em>Drosophila</em> homolog of human Wnt), leading to apoptosis. Our results indicate that E6 oncogene inhibits apoptosis by downregulating the expression of Wg, Dorsal, and Dif. Additionally, we find that Dorsal and Dif, not only promote apoptosis but also regulate autophagy and necrosis. Dorsal promotes autophagy while Dif counteracts it, inducing the formation of acidic vacuoles and necrosis. Interestingly, although E6 blocks the proapoptotic function of Dorsal and Dif, it lacks the ability to interfere with their role in apoptosis-independent cell death. Given the high conservation of NF-κB transcription factors our results provide new insight into potential mechanisms mediated by NF-κB to intervene with cell immortalization action of E6 oncoprotein in HPV-infected cells.</div></div>","PeriodicalId":52381,"journal":{"name":"Tumour Virus Research","volume":"19 ","pages":"Article 200316"},"PeriodicalIF":4.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They include the human papillomaviruses (HPV), Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpesvirus (KSHV), hepatitis viruses, and human polyomaviruses. Oncogenic viruses employ different mechanisms to induce cancer. Notably, cancer only develops in a minority of individuals who are infected, usually following protracted years of chronic infection. The human papillomaviruses (HPVs) are associated with the highest number of cancer cases, including cervical cancer and other epithelial malignancies. Hepatitis B virus (HBV) and the RNA virus hepatitis C (HCV) are significant contributors to hepatocellular cancer (HCC). Other oncoviruses include Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpes virus (KSHV), human T-cell leukemia virus (HTLV-I), and Merkel cell polyomavirus (MCPyV). The identification of these infectious agents as aetiological agents for cancer has led to reductions in cancer incidence through preventive interventions such as HBV and HPV vaccination, HPV-DNA based cervical cancer screening, antiviral treatments for chronic HBV and HCV infections, and screening of blood for transfusion for HBV and HCV. Successful efforts to identify additional oncogenic viruses in human cancer may provide further understanding of the aetiology and development of cancer, and novel approaches for prevention and treatment. Cervical cancer, caused by HPV, is the leading gynaecological malignancy in LMICs, with high age-standardised incidence and mortality rates, HCC due to HBV is an important cause of cancer deaths, and the burden of other cancer attributable to infections continues to rise globally. Hence, cancers attributable to DNA viruses have become a significant global health challenge.

We explored methylation for predicting HSIL+ in self- and clinician-collected samples from Papua New Guinea.</p><p>Methylation of <em>EPB41L3</em> (1–6 CpG-sites), <em>hTERT</em> (1–10 CpG-sites) and <em>FAM19A4</em> (1–5 CpG-sites) was assessed through pyrosequencing from 44 HPV+ samples (4 cancers, 19 HSIL, 4 low-grade squamous intraepithelial lesions (LSIL), 17 normal). New primers were designed for <em>FAM19A4</em> directed to the first exon region not explored previously.</p><p>In clinician-collected samples, methylation at CpG-sites 4 and 5 of <em>EPB41L3</em> were the best HSIL predictors (AUC &gt;0.83) and CpG-site 4 for cancer (0.925). Combination of <em>EPB41L3</em> sites 2/4 plus <em>FAM19A4</em> site 1 were the best HSIL+ markers [100% sensitivity, 63.2% specificity].</p><p>Methylation at CpG-site 5 of <em>FAM19A4</em> was the best HSIL predictor (0.67) in self-collected samples, and CpG-sites 1 and 3 of <em>FAM19A4</em> for cancer (0.77). Combined, <em>FAM19A4</em> site 1 plus HPV 16/18 detection yielded sensitivity of 82.6% and specificity of 61.9%.</p><p>In conclusion, methylation at individual CpG-sites of <em>EPB41L3</em> and <em>FAM19A4</em> outperformed global analysis and improved HSIL+ detection, warranting further investigation.</p></div>","PeriodicalId":52381,"journal":{"name":"Tumour Virus Research","volume":"18 ","pages":"Article 200288"},"PeriodicalIF":4.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666679024000120/pdfft?md5=211b8be54b2e08277c81b68123f37b1d&pid=1-s2.0-S2666679024000120-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141499638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
