Summary
Researchers sequenced the full-length HIV/R7/E-/GFP virus integrated into human cells. This 10,200-bp genome sequence provides valuable data on viral integration and host-pathogen interactions.
Area of Science:
- Virology
- Molecular Biology
- Genomics
Background:
- Understanding viral integration is crucial for studying persistent infections.
- The J-Lat 10.6 cell line is a model for studying human immunodeficiency virus (HIV) latency.
Purpose of the Study:
- To sequence the complete integrated genome of HIV/R7/E-/GFP in the J-Lat 10.6 cell line.
- To characterize the integration site and viral sequence.
Main Methods:
- Polymerase chain reaction (PCR) amplification of the integrated provirus.
- DNA sequencing of the amplified viral genome.
- Bioinformatic analysis and data submission to GenBank.
Main Results:
- A 10,200-bp full-length genome sequence of integrated HIV/R7/E-/GFP was obtained.
- The sequence included breakpoints at the human chromosome and provirus junctions.
- The acquired sequence data was successfully deposited in GenBank.
Conclusions:
- The study successfully characterized the complete integrated HIV genome in a cellular model.
- This detailed genomic data can aid in understanding HIV integration mechanisms and developing therapeutic strategies.

Retroviruses
14.4K
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’...

Non-LTR Retrotransposons
13.0K
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...

LTR Retrotransposons
19.2K
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.

Retrovirus Life Cycles
49.0K
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...

Immunodeficiency Diseases
1.8K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
