Summary
Human papillomavirus (HPV) infects basal cells, with E6 and E7 proteins potentially causing cancer. HPV virus-like particles (VLPs) show promise as a prophylactic vaccine against infection.
Area of Science:
- Virology
- Molecular Biology
- Oncology
Context:
- Human papillomavirus (HPV) is a common viral infection.
- Certain HPV genotypes are linked to cervical cancer.
- HPV oncogenes E6 and E7 play a role in cellular transformation.
Purpose:
- To describe the lifecycle and pathogenic mechanisms of HPV.
- To highlight the role of HPV E6 and E7 proteins in cell immortalization and malignancy.
- To discuss the development and efficacy of HPV virus-like particle (VLP) vaccines.
Summary:
- HPV infects basal epithelial cells, utilizing host cell machinery for replication.
- Viral E6 and E7 proteins disrupt tumor suppressors p53 and pRb, promoting cell proliferation and DNA damage.
- Integration of HPV DNA can lead to malignant transformation, with types 16 and 18 being high-risk.
- Production of HPV virus-like particles (VLPs) from the L1 capsid protein has enabled vaccine development.
Impact:
- Understanding HPV pathogenesis is crucial for cancer prevention strategies.
- HPV VLPs (types 6, 11, 16, 18) have demonstrated success in inducing type-specific neutralizing antibodies.
- This research supports the ongoing efforts in developing effective prophylactic HPV vaccines to reduce cancer incidence.

Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Cancer Vaccines
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
