Insights

Gastric cancer pathogenesis involves complex signaling pathways. Targeting these pathways, including developmental ones, offers potential for new drug development, though their roles need further study.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Signaling

Background:

  • Gastric cancer pathogenesis is multifactorial.
  • Dysregulated intracellular signaling pathways are common mechanisms.
  • Established oncogenic pathways (e.g., NF-κB, EGFR) and developmental pathways (e.g., TGF-β, Wnt) are implicated.

Purpose of the Study:

  • To review the role of intracellular signaling pathways in gastric carcinogenesis.
  • To highlight the significance of developmental signaling pathways in gastric cancer.
  • To provide a basis for targeted drug development.

Main Methods:

  • Literature review of signaling pathways in gastric cancer.
  • Analysis of established and emerging oncogenic pathways.
  • Discussion of developmental signaling pathways.

Main Results:

  • Multiple signaling pathways, including cell cycle regulators, NF-κB, COX-2, and EGFR, are involved in gastric carcinogenesis.
  • Developmental pathways such as TGF-β/BMP, Wnt/β-catenin, Hedgehog, and Notch signaling are increasingly recognized.
  • Cross-talk and relative importance of these pathways are not fully elucidated.

Conclusions:

  • Understanding these signaling pathways is crucial for developing targeted therapies for gastric cancer.
  • Further research is needed to clarify pathway interactions and their specific roles in gastric carcinogenesis.

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...
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.

Gastritis II: Pathophysiology01:26

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
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...
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
