Insights

Down-regulating Notch1 inhibits invasion and metastasis in lingual squamous cell carcinoma. This approach reduces matrix metalloproteinase (MMP)-2 and MMP-9 expression, offering potential new therapies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • The Notch signaling pathway is implicated in carcinoma invasion and metastasis.
  • Mechanisms of Notch1 in lingual squamous cell carcinoma (LSCC) invasion and migration remain unclear.

Purpose of the Study:

  • To investigate the role of Notch1 in LSCC invasion and metastasis.
  • To demonstrate the anti-invasion and anti-metastasis effects of Notch1 down-regulation in LSCC.

Main Methods:

  • Investigated the effect of Notch1 down-regulation in LSCC.
  • Assessed the expression of matrix metalloproteinase (MMP)-2 and MMP-9.

Main Results:

  • Down-regulation of Notch1 demonstrated an anti-invasion and anti-metastasis effect in LSCC.
  • Notch1 down-regulation inhibited the expression of MMP-2 and MMP-9.

Conclusions:

  • Notch1 down-regulation is a potential strategy to inhibit LSCC invasion and metastasis.
  • Targeting Notch1 may offer novel preventive and therapeutic strategies for LSCC.

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 until 1985...

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...
Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...
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.
