Insights

Notch 1 intracellular domain (NICD) is overexpressed in ovarian cancer, and its depletion inhibits cancer cell growth. This suggests Notch 1 is a potential therapeutic target for ovarian cancer treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • Advanced ovarian cancer remains a significant challenge despite current treatments.
  • The Notch signaling pathway is crucial for cell development and survival.
  • Novel therapeutic targets are needed for ovarian cancer.

Purpose of the Study:

  • To investigate the expression of Notch 1 intracellular domain (NICD) in ovarian cancer.
  • To determine the effect of NICD depletion on ovarian cancer cell proliferation.

Main Methods:

  • Analyzed NICD expression in ovarian cancer cell lines (OVCAR3, SKOV3, CaOV3) and human specimens using Western blot.
  • Depleted NICD in cell lines via siRNA transfection.
  • Assessed cell growth inhibition using MTT assay over 6 days.

Main Results:

  • Abundant NICD expression was found in all tested ovarian cancer cell lines and 76% of human samples.
  • Notch 1 siRNA effectively reduced NICD levels.
  • NICD depletion significantly inhibited the growth of all three ovarian cancer cell lines.

Conclusions:

  • NICD is frequently expressed in ovarian cancer.
  • Depleting Notch 1 inhibits ovarian cancer cell proliferation.
  • Notch 1 represents a promising therapeutic target for ovarian cancer.

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...
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.

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...
