Summary
A new deep learning method, ViroISDC, accurately detects Hepatitis B virus (HBV) integration sites in human genomes. This advancement improves understanding of HBV-related genomic instability and liver cancer development.
Area of Science:
- Genomics
- Virology
- Bioinformatics
Background:
- Hepatitis B virus (HBV) integration into human chromosomes can cause genomic instability and liver cancer (hepatocarcinogenesis).
- Existing methods for detecting HBV integration sites lack precision and stability.
Purpose of the Study:
- To develop and validate a novel deep learning-based method, ViroISDC, for accurate detection of HBV integration sites.
- To analyze HBV integration patterns and their association with hepatocarcinogenesis.
Main Methods:
- ViroISDC utilizes deep learning, generating grammar rules and encoding language data characteristics for integration site prediction.
- Performance was compared against established tools like Lumpy, Pindel, Seeksv, and SurVirus.
Main Results:
- ViroISDC demonstrated superior performance, reliability, stability, and generality compared to existing methods.
- It is less sensitive to sequencing depth and integration sequence length.
- Analysis revealed chromosomal preferences for HBV integration, a tendency to integrate into cancerous tissue, higher frequency in males, and association with cancer-related genes.
Conclusions:
- The ViroISDC pipeline offers enhanced precision and reliability for HBV integration site detection.
- It provides valuable insights into HBV infection, aiding in the diagnosis, treatment, and prognosis of hepatocellular carcinoma (HCC).

22.3K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

02:33Retroviruses
12.1K
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’...

1.2K
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...

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...

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.

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion...
