Insights

Diffuse-type gastric cancer exhibits invasive growth. Recurrent mutations in the RhoA gene suggest its activity may suppress tumors in this aggressive cancer subtype.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Diffuse-type gastric cancer is characterized by invasive growth and poor cellular adhesion.
  • The small GTPase RhoA plays a role in cellular processes relevant to cancer progression.

Purpose of the Study:

  • To investigate the role of RhoA mutations in diffuse-type gastric cancer.
  • To explore the potential tumor-suppressive function of RhoA activity in this disease context.

Main Methods:

  • Analysis of mutation data from recent studies on gastric cancer.
  • Investigating the correlation between RhoA gene mutations and tumor characteristics.

Main Results:

  • Highly recurrent mutations in the gene encoding RhoA were identified in diffuse-type gastric cancer.
  • These findings suggest a potential tumor-suppressive role for RhoA activity.

Conclusions:

  • RhoA mutations are frequent in diffuse-type gastric cancer.
  • RhoA activity may act as a tumor suppressor in this specific gastric cancer subtype, warranting further investigation.

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.

Small GTPases - Ras and Rho01:24

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.

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

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.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
