Area of Science:

  • Genetics
  • Molecular Biology
  • Oncology

Context:

  • Gastric carcinogenesis involves complex genetic and molecular alterations.
  • Understanding these changes is vital for effective cancer treatment.

Purpose:

  • To identify and describe the specific genetic and molecular alterations in gastric carcinogenesis.
  • To highlight the genes and chromosomal regions affected during stomach cancer development.

Summary:

  • This research elucidates the genetic landscape of gastric cancer, detailing alterations in genes encoding matrix metalloproteinases, growth factors, oncogenes, tumor suppressors, DNA repair enzymes, and cell adhesion molecules.

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...
Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
