Critical Reviews in Biochemistry and Molecular Biology
|March 2, 2021
Summary
Human immunodeficiency virus (HIV) and long interspersed element-1 (LINE-1) replication are inhibited by suppressors through distinct mechanisms. This review explores these alternative pathways, aiding future research.
Area of Science:
- Molecular Biology
- Virology
- Genetics
Background:
- Exogenous retroviruses like HIV and endogenous retroelements like LINE-1 replicate via reverse transcription.
- HIV causes AIDS, while LINE-1 is the only autonomously replicating retroelement.
- Previously, HIV and LINE-1 were thought to share similar replication processes, leading to shared inhibitors.
Purpose of the Study:
- To review suppressors that inhibit both HIV and LINE-1.
- To focus on the distinct mechanisms these suppressors employ against each.
- To propose reasons for these differential inhibitory pathways.
Main Methods:
- Literature review of suppressors affecting HIV and LINE-1.
- Analysis of distinct inhibitory mechanisms.
- Consideration of subcellular localization and cellular impact of LINE-1.
Main Results:
- Many suppressors utilize alternative pathways to inhibit HIV and LINE-1.
- Differences in HIV/LINE-1 activity and suppressor localization influence these pathways.
- LINE-1 retrotransposition impacts human cells differently than HIV infection.
Conclusions:
- Suppressors employ diverse strategies to inhibit HIV and LINE-1.
- Understanding these distinct mechanisms is crucial for targeted therapeutic development.
- Further research into these pathways will advance retroviral and retroelement control.

01:10Retrovirus Life Cycles
48.3K
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...

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’...

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

12.6K
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...

01:26Size and Structure of Viral Genomes
386
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...

03:08LTR Retrotransposons
18.7K
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.
