Summary
Hepatitis C virus (HCV) infection alters cellular gene expression, inducing proviral and antiviral factors like long noncoding RNAs (lncRNAs). Upregulated lncRNAs may drive liver cancer in chronic HCV patients.
Area of Science:
- Virology
- Molecular Biology
- Genomics
Background:
- Hepatitis C virus (HCV) infection establishes chronic disease by altering host cell transcriptomes.
- Cells activate antiviral pathways upon sensing HCV, while the virus evolves to evade or exploit these responses.
Purpose of the Study:
- To review proviral and antiviral factors, including proteins, microRNAs, and long noncoding RNAs (lncRNAs), induced during HCV infection.
- To explore the role of lncRNAs in HCV pathogenesis and their potential link to liver cancer development.
Main Methods:
- Literature review of studies on host-pathogen interactions in HCV infection.
- Analysis of transcriptomic changes and the identification of induced noncoding RNAs.
Main Results:
- HCV infection induces a complex interplay of proviral and antiviral factors.
- Several upregulated lncRNAs exhibit oncogenic functions, potentially contributing to liver tumorigenesis in HCV patients.
- Induced lncRNAs can regulate host gene expression, affecting viral replication and antiviral responses.
Conclusions:
- lncRNAs are significant players in the host response to HCV infection.
- Studying proviral and antiviral lncRNAs offers potential for novel discoveries in basic and translational research.
- lncRNA dysregulation may underlie the increased incidence of liver tumors in individuals with chronic HCV.

37
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

01:29Immune Response Against Viral Pathogens
2.5K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

1.3K
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...

01:30Inhibitors of Viral Protein Synthesis
26
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

02:33Retroviruses
15.9K
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
50.6K
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...
