Summary
We developed VISA, a vector integration site analysis server, to analyze next-generation sequencing data for retroviral vector integration sites. This tool helps determine genotoxic effects and aids mutagenesis screens.
Area of Science:
- Bioinformatics
- Genomics
- Molecular Biology
Background:
- Analyzing retroviral vector integration is crucial for assessing genotoxicity and developing safer therapeutic vectors.
- Identifying integration sites is essential for retroviral mutagenesis screens.
Purpose of the Study:
- To develop a computational tool for analyzing retroviral vector integration sites from next-generation sequencing data.
Main Methods:
- Developed VISA (Vector Integration Site Analysis) server.
- Mapped sequence reads containing provirus to the human genome.
- Filtered unlocalizable reads and determined unique integration sites based on alignment scores.
Main Results:
- VISA analyzes next-generation sequencing data to identify retroviral vector integration sites.
- The server filters reads and determines unique integration sites efficiently.
Conclusions:
- VISA provides a user-friendly web interface for uploading sequence files.
- Results are delivered in a concise tabular format for rapid analysis of retroviral vector integration sites.

15.9K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

1.1K
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

50.7K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

14.1K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

20.5K
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

01:51Mechanisms of Retrovirus-induced Cancers
7.2K
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...
