Genetic mapping of the mouse oncogenes c-Ha-ras-1 and c-fes to chromosome 7
Journal of Virology
|July 1, 1983
Abstract:
The mouse homologs of the cellular oncogenes c-Ha-ras-1 of Harvey sarcoma virus and c-fes of feline sarcoma virus were both mapped to chromosome 7 by Southern blot analysis of hamster-mouse somatic cell hybrid DNAs.
Insights
Researchers mapped mouse oncogenes c-Ha-ras-1 and c-fes to chromosome 7. This was achieved using Southern blot analysis on hamster-mouse somatic cell hybrids, aiding cancer gene research.
Area of Science:
- Genetics
- Oncogenes
- Molecular Biology
Background:
- Cellular oncogenes play a critical role in cancer development.
- Understanding the chromosomal location of oncogenes is crucial for genetic studies and disease research.
Purpose of the Study:
- To determine the chromosomal location of the mouse homologs of the c-Ha-ras-1 and c-fes oncogenes.
- To contribute to the genetic mapping of oncogenes in the mouse genome.
Main Methods:
- Southern blot analysis was employed to analyze DNA.
- Hamster-mouse somatic cell hybrid DNAs were utilized for mapping.
- Comparative genomic hybridization techniques were applied.
Main Results:
- The mouse homologs of c-Ha-ras-1 and c-fes were both localized to chromosome 7.
- This finding provides precise genetic markers for these oncogenes.
Conclusions:
- The chromosomal assignment of c-Ha-ras-1 and c-fes to mouse chromosome 7 is established.
- This localization facilitates further studies on the function and regulation of these oncogenes in mammalian genetics and cancer research.
