Summary
Retroviral integrase (IN) integrates viral DNA into the host genome, causing DNA damage. Endogenous retrovirus-K IN may contribute to genomic instability and diseases like cancer.
Area of Science:
- Molecular Biology
- Virology
- Genetics
Background:
- Retroviruses integrate into host genomes, forming proviruses.
- Retroviral genomes contain conserved regions including integrase (IN).
- IN is essential for viral DNA integration into the host genome.
Purpose of the Study:
- To investigate the role of endogenous retrovirus-K (ERVK) integrase (IN) in DNA damage.
- To explore the potential contribution of ERVK IN to genomic instability and human diseases.
Main Methods:
- Analysis of retroviral genome structure and function.
- Examination of the integrase-mediated DNA integration process.
- Review of host DNA repair mechanisms and their interaction with retroviral integration.
Main Results:
- Retroviral integration by IN causes DNA damage, necessitating host repair pathways.
- Failure in DNA repair pathways can lead to genomic instability and cell death.
- ERVK IN is proposed as a potential contributor to DNA damage in human cells.
Conclusions:
- ERVK IN activity warrants further investigation for its role in human diseases.
- Understanding ERVK IN's contribution to DNA damage could inform drug discovery for neurological diseases and 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...

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’...

13.8K
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...

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.

01:10Retrovirus Life Cycles
50.2K
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...

01:26Size and Structure of Viral Genomes
962
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...
