Failure to detect chromosome damage in vivo in Friend virus-infected leukemic mice
Journal of the National Cancer Institute
|February 1, 1975
Abstract:
The cytogenetic activity of Friend virus (FV) was tested in vivo on spleen and bone marrow cells of FV-infected leukemic C3H/HeJ and STS mice. No specific chromosome rearrangements were detected in the infected animals. Some chromosome abnormalities were recorded in both normal and diseased animals; however, aberrations did not significantly increase in the leukemic groups.
Insights
Friend virus (FV) infection did not cause specific chromosome rearrangements in leukemic mice. While some chromosome abnormalities were observed, they did not significantly increase in diseased animals, suggesting FV lacks direct cytogenetic activity.
Area of Science:
- * Virology
- * Cytogenetics
- * Oncology
Background:
- * Friend virus (FV) is known to cause leukemia in mice.
- * Understanding the viral mechanisms of oncogenesis is crucial.
Purpose of the Study:
- * To investigate the in vivo cytogenetic activity of Friend virus.
- * To determine if FV infection induces specific chromosome abnormalities in leukemic mice.
Main Methods:
- * In vivo study involving FV-infected C3H/HeJ and STS mice.
- * Analysis of spleen and bone marrow cells for chromosome abnormalities.
Main Results:
- * No specific chromosome rearrangements were identified in FV-infected leukemic mice.
- * Chromosome abnormalities were present in both normal and infected animals.
- * The frequency of aberrations did not significantly increase in leukemic groups.
Conclusions:
- * Friend virus does not appear to possess direct cytogenetic activity.
- * FV-induced leukemogenesis likely involves mechanisms other than direct chromosomal damage.
