Viruses with RNA Genomes01:29

Viruses with RNA Genomes

783
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...

MicroRNAs01:22

MicroRNAs

3.8K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

siRNA - Small Interfering RNAs

18.3K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms 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...

Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

698
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Area of Science:

  • Hepatology
  • Virology
  • Molecular Biology

Background:

  • Hepatitis C virus (HCV) affects millions globally, leading to severe liver conditions like cirrhosis and cancer.
  • Direct-acting antiviral (DAA) drugs offer high cure rates, but long-term outcomes require further study.
  • MicroRNAs (miRNAs) are critical in HCV infection, influencing host factors essential for viral replication and cell growth.

Purpose of the Study:

  • To review the role of miRNAs in the HCV life cycle.
  • To explore the coordinated regulation of miRNAs in HCV-mediated liver disease progression.
  • To highlight the potential of circulating miRNAs as diagnostic and prognostic biomarkers.

Main Methods:

  • Literature review of recent studies on miRNAs and HCV.
  • Analysis of miRNA involvement in host-pathogen interactions.
  • Examination of miRNA regulatory networks in HCV pathogenesis.

Main Results:

  • Altered miRNA expression is implicated in HCV pathogenesis by controlling immune response, proliferation, and apoptosis.
  • miRNAs act as intercellular communicators within the liver during HCV infection.
  • miRNAs are crucial for HCV replication and host cell modulation.

Conclusions:

  • miRNAs play a significant role in HCV infection and the progression of liver disease.
  • Circulating miRNAs may serve as valuable biomarkers for disease progression and early therapeutic intervention in end-stage liver disease.
  • Further research into miRNA function can lead to novel diagnostic and therapeutic strategies for HCV.
