NOTCH signaling

Area of Science:

  • Oncology
  • Neuroscience
  • Molecular Biology

Background:

  • NOTCH signaling is vital for tissue homeostasis.
  • Its role in cancer is complex, acting as both an oncogene and tumor suppressor.
  • Gliomas are aggressive brain tumors where NOTCH's function is debated.

Purpose of the Study:

  • To review the context-dependent role of NOTCH signaling in tumorigenesis.
  • To focus on the specific role of NOTCH in glioma development and progression.
  • To reconcile conflicting evidence regarding NOTCH's function in gliomas.

Main Methods:

  • Literature review of existing research on NOTCH signaling in cancer.
  • Analysis of studies investigating NOTCH's role in glioma subtypes.
  • Discussion of recent findings and unresolved questions.

Main Results:

  • NOTCH signaling can promote or suppress tumor development depending on the context.
  • Historically viewed as an oncogene in glioma due to neural stem cell promotion.
  • NOTCH-inactivating mutations in some gliomas challenge its oncogenic role, suggesting context-specific functions.

Conclusions:

  • The role of NOTCH signaling in glioma is complex and context-dependent.
  • Recent findings necessitate a re-evaluation of NOTCH's function in different glioma subtypes.
  • Further research is needed to fully understand and potentially target NOTCH signaling in brain tumors.

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Loss of Tumor Suppressor Gene Functions01:12

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...

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,...

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...
