rous sarcoma
Very lowTechnical/Scientific
Definition
Meaning
A specific type of virus-induced malignant tumour in chickens, historically significant as the first cancer shown to be caused by a virus.
In modern biology, it refers to the disease caused by the Rous sarcoma virus (RSV), a retrovirus used extensively as a model system in cancer research to study oncogenesis, cell transformation, and viral replication.
Linguistics
Semantic Notes
Always capitalized ('Rous'). The term is a proper noun eponym (from Peyton Rous) combined with the common noun 'sarcoma'. It refers exclusively to the virus-induced avian tumour and the associated viral model system.
Dialectal Variation
British vs American Usage
Differences
No significant differences in usage. Spelling remains identical.
Connotations
Identical scientific connotations. Associated with foundational oncology/virology research.
Frequency
Extremely rare in general language. Frequency is equal and confined to specialised biological/medical literature in both regions.

Examples
By Part of Speech
adjective
British English
- The Rous sarcoma genome was sequenced.
- Rous sarcoma research continues.
American English
- The Rous sarcoma model is fundamental.
- Rous sarcoma virus stocks were prepared.
Examples
By CEFR Level
- Rous sarcoma is a type of animal cancer.
- The discovery of Rous sarcoma virus was a milestone in cancer research.
- Oncogenic transformation by Rous sarcoma virus is mediated by the v-src tyrosine kinase, which perturbs normal cellular signalling pathways.
Learning
Memory Aids
Mnemonic
Think of a ROUgh, angry chicken (a Rous) with a lump (sarcoma), representing the first virus-linked cancer discovered in fowl.
Conceptual Metaphor
PIONEERING MODEL: The disease is metaphorically a 'Rosetta Stone' or 'foundational model' for understanding viral carcinogenesis.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'Rous' as 'грубый' (rough). It is an untranslated surname. The correct term is 'Саркома Рауса'.
- Do not treat 'sarcoma' as a general term for cancer; it is a specific type (connective tissue).
Common Mistakes
- Misspelling as 'Rouse' sarcoma.
- Using lowercase 'r' (it must be capitalized).
- Assuming it is a human disease (primarily avian).

FAQ
Frequently Asked Questions
No, it is primarily a disease of chickens and is used as a laboratory model. The virus does not naturally infect humans.
Its discovery by Peyton Rous in 1911 provided the first evidence that a virus could cause cancer, a foundational concept in oncology and virology.
It stands for Rous Sarcoma Virus, the retrovirus responsible for causing the tumour.
In a research context, it is a model for studying cancer mechanisms, not a condition for which treatment is typically sought outside of laboratory settings.
