Insights

Loss of tumor suppressor genes, like the retinoblastoma gene, is key in many cancers. Inactivation of this gene is broadly involved in lymphoid cancers, suggesting a role in hematopoietic neoplasms.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Tumor suppressor genes (anti-oncogenes) are crucial in preventing cancer development.
  • The retinoblastoma gene is a key tumor suppressor gene.
  • Its inactivation is linked to various solid tumors and increasingly to lymphoid malignancies.

Purpose of the Study:

  • To review the role of the retinoblastoma gene in normal lymphocyte cell division.
  • To explore the consequences of retinoblastoma gene inactivation in lymphoid neoplasia.
  • To assess the involvement of retinoblastoma gene inactivation across diverse lymphoid cancers.

Main Methods:

  • Literature review of studies on retinoblastoma gene function.
  • Analysis of existing data on retinoblastoma gene status in lymphomas and leukemias.
  • Synthesis of findings regarding retinoblastoma gene inactivation in hematopoietic neoplasms.

Main Results:

  • The retinoblastoma gene plays a role in regulating normal lymphocyte proliferation.
  • Inactivation of the retinoblastoma gene is broadly implicated in non-Hodgkin's lymphomas.
  • Retinoblastoma gene inactivation is also frequently observed in lymphocytic leukemia.

Conclusions:

  • Retinoblastoma gene inactivation is a significant mechanism in the pathogenesis of lymphoid cancers.
  • These findings suggest a broader role for tumor suppressor genes in hematopoietic neoplasms.
  • Further research into tumor suppressor gene involvement in blood cancers is warranted.

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

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...
The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a superfamily...

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...
The Retinoblastoma Gene01:20

The Retinoblastoma Gene

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,...
