Abstract

Insights

Viral oncogenes interfere with cell cycle control and apoptosis, promoting cancer development. Understanding these mechanisms may lead to new cancer treatments targeting viral proteins and cellular pathways.

Area of Science:

  • Molecular Biology
  • Virology
  • Oncology

Background:

  • Oncogenic viruses and cell cycle control proteins are rapidly advancing research fields.
  • Viral infections are increasingly linked to apoptosis and cell cycle pathway disruption.

Purpose of the Study:

  • To elucidate the mechanisms by which viral proteins regulate apoptosis.
  • To understand how viral proteins target cellular pathways.
  • To explore potential new cancer remedies based on these interactions.

Main Methods:

  • Literature review of English-language publications from January 1995 to August 1998.
  • Focus on breakthroughs in over one hundred research papers from the past three years.
  • Selection criteria prioritized DNA viruses implicated in human cancer development.

Main Results:

  • Certain DNA viruses possess oncogenic proteins capable of transforming cells and inducing tumors.
  • These viral proteins target cellular pathways, inhibiting receptor-induced or signal transduction-induced apoptosis.
  • Viral interference with host cell apoptosis enhances viral replication and may promote carcinogenesis.

Conclusions:

  • Viral oncogenic proteins play a critical role in cancer development by manipulating host cell processes.
  • Key cellular regulators, including oncogenes and tumor suppressor genes (e.g., Retinoblastoma (RB) and p53), are involved in these viral-host interactions.
  • Targeting these viral mechanisms offers a promising avenue for novel cancer therapies.

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

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...

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.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
