Summary
Endogenous retroviruses are ancient viral sequences integrated into vertebrate genomes. Studying these provide insights into viral evolution, host genome changes, and the impact of life history and environment on viral spread.
Area of Science:
- Evolutionary biology
- Genomics
- Virology
Background:
- Endogenous retroviruses (ERVs) are abundant genetic sequences in vertebrate genomes.
- They represent ancient retroviral infections and have been a constant presence in vertebrate evolution.
- ERVs are linked to exogenous retroviruses, offering a historical perspective on viral activity.
Purpose of the Study:
- To explore the evolutionary impact of endogenous retroviruses on host genomes.
- To utilize ERV data for understanding viral spread and adaptation over evolutionary time.
- To investigate how life-history traits and environmental factors influence viral dynamics.
Main Methods:
- Analysis of endogenous retrovirus genetic loci in extant vertebrates.
- Integration of population genetics and evolutionary theory with retrovirus biology.
- Comparative genomics to trace viral evolutionary pathways.
Main Results:
- Endogenous retroviruses act as mutagens and sources of genetic novelty in host genomes.
- ERV data reveals patterns of viral spread and adaptation across evolutionary timescales.
- Studies show correlations between life-history traits, ecological, and geological events and viral movement.
Conclusions:
- Endogenous retroviruses are crucial for understanding host-virus co-evolution.
- ERV analysis offers a powerful retrospective tool for evolutionary and epidemiological studies.
- Viral evolution is shaped by a complex interplay of host genetics, life history, and environmental pressures.

15.7K
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’...

01:10Retrovirus Life Cycles
50.5K
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
1.0K
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...

20.4K
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.

14.0K
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...

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...
