Summary
Human endogenous retroviruses (HERVs), ancient viral remnants in our genome, are active players in human biology and disease. Understanding HERV roles in immunity, development, and conditions like cancer and neurodegeneration is crucial for clinical applications.
Area of Science:
- Genomics
- Molecular Biology
- Evolutionary Biology
Background:
- Human endogenous retroviruses (HERVs) comprise approximately 8% of the human genome.
- Once considered genetic fossils, HERVs have evolved and acquired functional roles impacting host biology.
Purpose of the Study:
- To provide a comprehensive review of HERV origins, evolution, and genomic organization.
- To explore the regulatory mechanisms controlling HERV expression.
- To synthesize evidence on the dual role of HERVs in health and disease.
Main Methods:
- Review of existing literature on HERV origins, evolution, and function.
- Analysis of genomic organization and recombination patterns.
- Synthesis of data linking HERV activity to various physiological and pathological processes.
Main Results:
- HERVs exhibit significant structural diversity and complex genomic organization.
- HERV expression is regulated by epigenetic modifications, cellular factors, and environmental influences.
- HERV activity is implicated in immune modulation, tumorigenesis, autoimmunity, and neurodegeneration.
Conclusions:
- HERVs are active genomic elements with a dual role in human physiology and pathology.
- Understanding HERVs offers potential for biomarker discovery and therapeutic target development.
- Systematic investigation of HERVs is highly relevant for clinical applications.

606
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...

02:33Retroviruses
14.5K
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
49.1K
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...

19.3K
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
6.8K
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...

03:18Non-LTR Retrotransposons
13.1K
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...
