Summary
Canine lymphomas were studied using molecular genetics. A specific N-ras gene mutation (glycine to aspartic acid) was found in codon 13 of a young dog
Area of Science:
- Veterinary oncology
- Molecular genetics
- Canine cancer research
Background:
- Lymphoma is a common cancer in dogs.
- The N-ras gene is frequently implicated in various cancers.
- Specific codons (12, 13, 61) in N-ras are known mutation hotspots.
Purpose of the Study:
- To investigate canine lymphomas using molecular genetic techniques.
- To screen for mutations in critical regions of the N-ras gene in canine lymphoma cases.
Main Methods:
- Molecular genetic analysis was employed.
- Exons 1 and 2 of the N-ras gene were screened for mutations.
- Focus was placed on mutation hotspots within the N-ras gene.
Main Results:
- A specific mutation was identified in a canine lymphoma case.
- The mutation involved a GGT to GAT change (glycine to aspartic acid).
- This mutation was located in codon 13 of the N-ras gene.
Conclusions:
- The study identified a specific N-ras gene mutation in a canine multicentric lymphoma.
- This finding contributes to understanding the molecular basis of canine lymphoma.
- Highlights the role of N-ras gene mutations in canine cancer.

02:23Abnormal 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 daughter...
02:38The 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.

01:03Rous 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.

01:20The 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,...
