Abstract

Insights

Elevated RHOC gene expression in gastric cancer correlates with metastasis. This suggests RHOC may predict metastatic potential in gastric carcinomas, aiding in early detection and treatment strategies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • RHOC, a RAS-related small GTPase, influences cell structure and transformation.
  • RHOC is implicated in melanoma cell metastasis.
  • Its role in gastric cancer progression requires elucidation.

Purpose of the Study:

  • To investigate the biological significance of RHOC in gastric carcinogenesis.
  • To determine the association between RHOC expression and gastric cancer metastasis.

Main Methods:

  • Quantitative RT-PCR was used to analyze RHOC gene expression.
  • Gastric carcinoma tissues (51 cases) and cell lines (8 cases) were examined.
  • Expression levels were compared between primary tumors, metastatic tumors, and nonneoplastic mucosa.

Main Results:

  • RHOC expression was significantly higher in gastric tumors with metastasis compared to those without.
  • RHOC levels in primary and metastatic tumors exceeded those in adjacent nonneoplastic tissue.
  • RHOC mRNA expression was detected in gastric carcinoma cell lines.

Conclusions:

  • Increased RHOC gene expression is linked to gastric carcinoma metastasis.
  • RHOC may serve as a valuable genetic marker for predicting metastatic potential.
  • Further research into RHOC's role could inform therapeutic interventions.

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
Cell Polarization by Rho Proteins01:21

Cell Polarization by Rho Proteins

Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.

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...
