[Damaging effect of 2 simian viruses on mammalian cell chromosomes]
Abstract:
A green monkey myxovirus (SV5) causes chromosome breaks in embryonal diploid fibroblasts of man, cotton rats, striped hairy-footed hamster, and in cells of one heteroploid line of newborn lamb kidney. Adenovirus SV15 is mutagenic for all cultures under study (diploid strains of human and cotton rat embryo fibroblasts and three continuous kidney cell lines from newborn lambs). The mutagenic activity of these viruses may be manifested without their undergoing a complete cycle of replication.
Insights
Simian virus 5 (SV5) and Adenovirus SV15 cause genetic damage, including chromosome breaks, in various animal and human cells. This mutagenic effect can occur even if the viruses do not fully replicate within the host cells.
Area of Science:
- Virology
- Genetics
- Cell Biology
Context:
- Investigating the genotoxic potential of viral infections.
- Understanding the mechanisms of viral-induced DNA damage.
Purpose:
- To determine if simian virus 5 (SV5) and Adenovirus SV15 exhibit mutagenic properties.
- To assess viral mutagenicity across different cell types and replication states.
Summary:
- Simian virus 5 (SV5) induces chromosome breaks in human, cotton rat, hamster, and lamb kidney cells.
- Adenovirus SV15 demonstrates mutagenic activity in human and cotton rat fibroblasts, and lamb kidney cell lines.
- Viral mutagenicity was observed even without complete viral replication.
Impact:
- Highlights the potential for certain viruses to cause genetic instability.
- Informs understanding of viral pathogenesis and oncogenesis.
- Suggests non-replicative viral particles may still pose genotoxic risks.
