Insights

Notch signaling, a primitive pathway, is implicated in cancer development. This review explores how Notch signaling drives breast cancer progression by regulating epithelial-mesenchymal transition (EMT).

Area of Science:

  • Molecular Biology
  • Developmental Biology
  • Oncology

Background:

  • Notch signaling is crucial for multicellular organism development.
  • Aberrations in Notch signaling are linked to cancer, with Notch recognized as an oncogene for over two decades.
  • Activated Notch signaling and its target genes are observed in human breast cancer, correlating with poor prognosis.

Purpose of the Study:

  • To review recent advancements in understanding Notch-mediated regulation of epithelial-mesenchymal transition (EMT) in breast tumorigenesis.
  • To elucidate the molecular mechanisms by which Notch signaling influences breast cancer development.

Main Methods:

  • Literature review of recent progress in breast cancer research.
  • Analysis of molecular mechanisms linking Notch signaling to EMT.
  • Exploration of Notch's role in breast carcinogenesis and metastasis.

Main Results:

  • Notch signaling plays a key role in breast carcinogenesis.
  • Notch signaling regulates epithelial-mesenchymal transition (EMT), a process hijacked by cancer cells for metastasis.
  • Over-expression of Notch ligands and receptors is associated with poor breast cancer prognosis.

Conclusions:

  • Notch signaling is a significant factor in breast cancer development and progression.
  • Understanding Notch-mediated EMT is crucial for developing new therapeutic strategies against breast cancer.
  • Further research into Notch's molecular mechanisms can provide new insights into tumorigenesis.

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...

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

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.

Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

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...
