Abstract

Insights

Notch1 is upregulated in tongue cancer, promoting tumor growth and spread. Inhibiting Notch1 (Notch family of transmembrane proteins) reduces cancer cell proliferation and increases apoptosis, suggesting it as a therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology

Background:

  • The role of Notch1 in tongue cancer is controversial.
  • Notch1 signaling is known to influence tumor biology in a context-dependent manner.

Purpose of the Study:

  • To investigate the specific roles of Notch1 in tongue cancer.
  • To determine if Notch1 acts as an oncogene or tumor suppressor in this cancer type.

Main Methods:

  • Immunohistochemistry was used to compare Notch1 expression in tongue cancer and normal tissues.
  • In vitro studies involved transfecting tongue cancer cells with siRNA or plasmids to modulate Notch1 levels.
  • In vivo studies utilized a subcutaneous tumor model in mice.

Main Results:

  • Notch1 expression was significantly upregulated in tongue carcinoma tissues, correlating with tumor stage and differentiation.
  • Overexpression of Notch1 enhanced tongue cancer cell proliferation, migration, and invasion.
  • Inhibition of Notch1 decreased proliferation, migration, and invasion, while promoting apoptosis in vitro and in vivo.

Conclusions:

  • Notch1 plays a clear oncogenic role in tongue cancer.
  • These findings support Notch1 as a potential therapeutic target for tongue cancer treatment.

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...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...
