Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

5.9K
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

5.8K
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...

Cancers Originate from Somatic Mutations in a Single Cell

13.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Cancer-Critical Genes I: Proto-oncogenes

9.8K
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.
Such genes that act...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.4K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Summary

Retrogenes, gene copies from retroposition, are crucial in evolution and cancer. Their expression links to cancer subtypes, stages, and therapy response, particularly in primates and human carcinogenesis.

Area of Science:

  • Genomics
  • Evolutionary Biology
  • Cancer Research

Background:

  • Retrogenes are gene copies formed by retroposition of messenger RNA (mRNA).
  • These duplicates can acquire functionality and play roles in genome evolution, earning them the name 'seeds of evolution'.
  • Retrogenes are implicated in species evolution and also in the evolution of neoplastic tumors.

Purpose of the Study:

  • To review current knowledge on retrogenes in the context of cancer and evolution.
  • To explore the role of retrogenes in neoplastic transformation and tumor evolution.
  • To investigate phylogenetic insights into cancer-related retrogenes.

Main Methods:

  • Literature review summarizing existing research on retrogenes.
  • Analysis of retrogene expression patterns in relation to cancer characteristics.
  • Phylogenetic analysis of cancer-related retrogenes.

Main Results:

  • Retrogenes contribute to species evolution and are involved in cancer evolution.
  • Specific retrogene expression correlates with cancer subtypes, stages, and therapeutic outcomes.
  • Most cancer-related retrogenes originated in primate lineages, highlighting their significance in human carcinogenesis.

Conclusions:

  • Retrogenes are significant players in both normal evolution and cancer development.
  • Understanding retrogene roles can offer insights into cancer subtypes and treatment responses.
  • The prevalence of cancer-related retrogenes in primates underscores their importance in human cancer.
