Epigenetic Alterations in Human Papillomavirus-Associated Cancers

Area of Science:

• Virology
• Cancer Biology
• Epigenetics

Background:

• Viruses, including human papillomaviruses (HPVs), cause 15-20% of human cancers.
• Oncogenic viruses reprogram host cellular signaling pathways, impacting immunity, proliferation, and cell death.
• Studying viruses has elucidated fundamental cellular processes like mRNA splicing, oncogenes, and cell cycle control.

Purpose of the Study:

• To review current knowledge on epigenetic regulation in HPV-infected cells.
• To focus on epigenetic elements relevant to HPV-induced carcinogenesis.
• To highlight the potential of epigenetic modifications in cancer therapy.

Main Methods:

• Literature review of studies on HPV and epigenetics.
• Analysis of epigenetic silencing/de-silencing in HPV-associated cancers.
• Focus on reversible epigenetic modifications for therapeutic strategies.

Main Results:

• Epigenetic changes in HPV-infected cells mimic genetic mutations, affecting gene expression.
• Tumor viruses, especially HPV, are crucial models for studying the cancer epigenome.
• Reversible epigenetic modifications offer a promising avenue for cancer treatment.

Conclusions:

• Epigenetic dysregulation plays a significant role in HPV-mediated carcinogenesis.
• Understanding these epigenetic alterations is key to developing targeted therapies.
• Epigenetic therapy presents a viable strategy for treating HPV-associated cancers.
