Insights

Altered ribosome biogenesis, not tied to genetic mutations, increases cancer risk. Both overproduction and dysfunction of ribosomes can promote tumor development, offering new insights into cancer mechanisms.

Area of Science:

  • Molecular Biology
  • Oncology
  • Cellular Biology

Background:

  • Many diseases increase cancer risk without genetic mutations in oncogenes or tumor suppressors.
  • Altered ribosome biogenesis (quantitative/qualitative changes) is observed in some of these conditions.
  • Both ribosome overproduction and ribosome dysfunction are linked to increased tumor incidence.

Purpose of the Study:

  • To explore the mechanisms linking ribosome biogenesis alterations to tumorigenesis.
  • To discuss recent insights into how ribosome biogenesis impacts cancer development.
  • To connect non-genetic pathological conditions to cancer risk via ribosome function.

Main Methods:

  • Review of recent scientific literature on ribosome biogenesis and cancer.
  • Analysis of mechanisms underlying ribosome biogenesis dysregulation.
  • Correlation of cell growth stimulation and inherited disorders with tumor onset.

Main Results:

  • Up-regulation of ribosome biogenesis during abnormal cell growth correlates with cancer risk.
  • Intrinsic ribosome dysfunctions, seen in inherited disorders, also increase tumor incidence.
  • These findings highlight non-genetic pathways contributing to tumorigenesis.

Conclusions:

  • Alterations in ribosome biogenesis are significant contributors to cancer development.
  • Understanding these mechanisms provides new avenues for cancer research and prevention.
  • Ribosome biogenesis is a critical factor in tumorigenesis, independent of traditional genetic drivers.

Loss of Tumor Suppressor Gene Functions

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.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
