Abstract

Insights

The hedgehog (Hh) signaling pathway is activated in gastric cancer, particularly in undifferentiated types with lymph node metastasis. Inhibiting this pathway suppressed cancer cell growth, suggesting it

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • The hedgehog (Hh) signaling pathway is implicated in the development of various cancers.
  • Evidence suggests Hh pathway activation in gastric cancer warrants further investigation.

Purpose of the Study:

  • To analyze Hh pathway activation in gastric cancer.
  • To evaluate the Hh pathway as a potential therapeutic target.

Main Methods:

  • Immunohistochemical analysis of surgically resected gastric carcinoma specimens and lymph nodes.
  • Quantification of Gli1 nuclear translocation as a marker for Hh pathway activation.

Main Results:

  • Higher Gli1 nuclear localization observed in undifferentiated-type gastric tumors compared to differentiated types.
  • Positive correlation between Gli1 nuclear staining in primary tumors and lymph node metastasis.
  • In vitro suppression of gastric cancer cell growth by cyclopamine, a Hh pathway inhibitor.

Conclusions:

  • The Hh pathway is a potential therapeutic target for gastric cancer, especially undifferentiated types.
  • Hh pathway activation is linked to metastasis in gastric cancer.

Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

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...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
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 results in tumor...
