Abstract

Insights

Pancreatic cancer therapy can be improved by targeting the Notch and Hedgehog pathways. Inhibiting Notch induces cancer cell apoptosis, while Hedgehog inhibition enhances drug delivery, suggesting synergistic effects for future pancreatic adenocarcinoma treatments.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Signaling Pathways

Background:

  • Pancreatic adenocarcinoma is a leading cause of cancer death globally, with poor prognosis.
  • Current treatments require adjuncts due to rapid disease progression and high mortality.
  • Embryonic signaling pathways, including Notch, are implicated in pancreatic cancer development.

Purpose of the Study:

  • To review the Notch pathway's role in pancreatic pathophysiology and carcinogenesis.
  • To highlight Notch as a therapeutic target for pancreatic cancer.
  • To explore combination therapies involving Notch and other signaling pathways.

Main Methods:

  • Review of existing literature on the Notch pathway in pancreatic cancer.
  • Analysis of the crosstalk between Notch and other survival pathways.
  • Discussion of potential therapeutic strategies targeting these pathways.

Main Results:

  • Gamma-secretase inhibitors show potential for pancreatic cancer treatment.
  • Combination therapy with drugs targeting survival pathways (e.g., Hedgehog) may be beneficial.
  • Notch pathway modulation affects pancreatic cancer cell apoptosis and drug delivery.

Conclusions:

  • Notch pathway downregulation inhibits pancreatic cancer cell growth and promotes apoptosis.
  • Hedgehog pathway inhibition can improve drug delivery to pancreatic tumors.
  • Combined inhibition of Notch and Hedgehog pathways demonstrates synergistic potential for pancreatic adenocarcinoma therapeutics, pending safety evaluations.

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 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...
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 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 results in tumor...
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...
