Summary
Human immunodeficiency virus (HIV) microRNAs (miRNAs) show significant diversity, potentially influencing disease. A specific HIV miRNA, miR-H1, exhibits mutations and deletions, possibly linked to AIDS-related lymphoma.
Area of Science:
- Virology
- Molecular Biology
- Genetics
Background:
- MicroRNAs (miRNAs) play roles in viral processes, including oncogenesis.
- Studies on HIV-encoded miRNAs have yielded conflicting results.
- HIV's high mutation rate raises questions about miRNA stability and function.
Purpose of the Study:
- To investigate mutations in a suspect HIV miRNA (miR-H1).
- To explore the potential impact of HIV miRNA evolvability on disease pathogenesis.
- To examine structural diversity and potential disease associations of HIV miR-H1.
Main Methods:
- Analysis of 1293 HIV miR-H1 sequences from diverse tissues of seven patients.
- Examination of sequence mutations, deletions, and structural integrity.
Main Results:
- Significant structural diversity was observed in HIV miR-H1 sequences.
- A patient-specific deletion within miR-H1 was identified.
- Potential for new miRNA formation due to deletions was noted.
- A less stable miR-H1 structure showed a potential association with AIDS-related lymphoma (ARL).
Conclusions:
- HIV miRNAs, like miR-H1, are structurally diverse and prone to mutations and deletions.
- This diversity may contribute to varied HIV disease progression.
- HIV miR-H1 instability could be linked to the development of ARL.

00:36Viral Mutations
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
01:26Size and Structure of Viral Genomes
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...
01:19Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
01:10Retrovirus Life Cycles
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 retrovirus to...
02:33Retroviruses
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’...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
