Human papillomavirus (HPV) genome integration correlates with cervical lesion severity. Viral oncoproteins E5, E6, and E7 drive cancer hallmarks, with new insights from next-generation sequencing aiding biomarker discovery.
Area of Science:
- Oncology
- Virology
- Molecular Biology
Background:
- Cervical cancer (CC) remains a significant global health issue, particularly in low-income nations.
- Human papillomavirus (HPV) research has advanced CC understanding, yet critical questions persist.
- This review focuses on recent findings in CC pathogenesis and HPV oncogenesis.
Purpose of the Study:
- To discuss the latest advancements in cervical cancer pathogenesis and HPV oncogenesis.
- To highlight molecular alterations identified using next-generation technologies.
- To explore the roles of viral oncoproteins E5, E6, and E7 in cancer development.
Main Methods:
- Review of current literature on cervical cancer and human papillomavirus.
- Analysis of findings from next-generation sequencing technologies (genomics, transcriptomics, proteomics, metabolomics, epigenomics).
- Examination of the functional roles of HPV oncoproteins E5, E6, and E7.
Main Results:
- A correlation exists between HPV genome integration and the severity of cervical lesions.
- HPV oncoproteins E5, E6, and E7 contribute to cancer hallmarks like proliferation and immune evasion.
- Next-generation technologies reveal extensive molecular changes in CC, offering potential biomarkers.
Conclusions:
- HPV genome integration is implicated in cervical cancer progression.
- Viral oncoproteins E5, E6, and E7 play crucial roles in establishing and maintaining cancer characteristics.
- Advanced molecular profiling identifies novel targets for CC diagnosis, prognosis, and treatment.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
