Transduction of Human Cells with Polymer-complexed Ecotropic Lentivirus for Enhanced Biosafety
Published on: July 24, 2011
Abstract:
Interference with the cell cycle by vinblastine sulfate immediately after cells were infected with Rous sarcoma virus had little effect on the a development of two metabolic changes that occur in transformed cells. These results, along with an earlier demonstration of morphological changes developing in infected nondividing cells, demonstrate that the phenotypic development of the malignant state can occur without the intervention of cell divisions after infection by Rous sarcoma virus.
Insights
Vinblastine sulfate did not affect metabolic changes in Rous sarcoma virus-infected cells. Malignant transformation can occur without cell division, even in non-dividing cells.
Area of Science:
- Oncology
- Cell Biology
- Virology
Background:
- Rous sarcoma virus (RSV) infection induces cellular transformation, leading to malignant phenotypes.
- Cell division is often considered a prerequisite for the development of cancerous traits.
Purpose of the Study:
- To investigate whether cell cycle interference affects the development of metabolic changes in RSV-transformed cells.
- To determine if cell division is essential for the phenotypic manifestation of malignancy post-RSV infection.
Main Methods:
- Cells were infected with Rous sarcoma virus.
- Vinblastine sulfate was administered immediately after infection to interfere with the cell cycle.
- Metabolic and morphological changes in infected cells were monitored.
Main Results:
- Interference with the cell cycle using vinblastine sulfate had minimal impact on the development of two key metabolic alterations in transformed cells.
- Morphological changes associated with malignancy were observed in infected, non-dividing cells.
Conclusions:
- The phenotypic development of the malignant state, including metabolic and morphological changes, can occur independently of cell division following Rous sarcoma virus infection.
- Cellular transformation and the development of cancerous characteristics do not strictly require cell proliferation after viral oncogenesis.

00:57Viral Recombination
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
00:36Viral Mutations
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
01:33Bacterial Transformation
In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...
01:51Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
01:26Transformation
Microbial communities are dynamic environments where cell lysis releases free DNA into the surroundings. Other cells can take up this extracellular DNA through a process known as transformation.When a cell incorporates this foreign DNA into its genome, resulting in genetic modification, the process is known as transformation. Cells capable of this process are termed competent. Competence can be natural, as observed in certain bacteria and archaea, or artificially induced in the...
01:16Transduction
Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome are...
