Viral Mutations00:36

Viral Mutations

32.3K
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...

Viral Recombination

23.4K
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.

Eukaryotic Evolution

34.1K
The endosymbiont theory is the most widely accepted theory of eukaryotic evolution; however, its progression is still somewhat debated. According to the nucleus-first hypothesis, the ancestral prokaryote first evolved a membrane to enclose DNA and form the nucleus. Conversely, the mitochondria-first hypothesis suggests that the nucleus was formed after endosymbiosis of mitochondria.
Contrary to the endosymbiont theory, the eukaryote-first hypothesis proposes that the simpler prokaryotic and...

Rous Sarcoma Virus (RSV) and Cancer

5.1K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Retroviruses02:33

Retroviruses

12.3K
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’...

Mechanisms of Retrovirus-induced Cancers01:51

Mechanisms of Retrovirus-induced Cancers

5.1K
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...

Area of Science:

  • Veterinary Virology
  • Oncology
  • Molecular Biology

Background:

  • Papillomaviridae infect vertebrates, causing significant health impacts in humans and animals.
  • While over 250 human papillomavirus (HPV) types are known, animal PV discovery lags, with sheep being particularly understudied.
  • Animal PV infections range from asymptomatic to benign lesions and cancer, with most research focused on cattle, dogs, horses, and cats.

Purpose of the Study:

  • To provide a comprehensive review of ovine papillomaviruses (PVs).
  • To consolidate information on ovine PV taxonomy, evolution, genome, tropism, pathogenesis, clinical signs, and diagnostics.
  • To discuss the veterinary and public health implications of ovine PVs and suggest future research directions.

Main Methods:

  • Comprehensive literature review of ovine papillomaviruses.
  • Critical analysis of existing data on viral features, pathogenesis, and diagnostics.
  • Synthesis of information regarding taxonomy, genome organization, tropism, and clinical manifestations.

Main Results:

  • Limited number of ovine PV types identified to date.
  • Ovine PV infections can manifest as benign papillomas or progress to more severe conditions.
  • Current diagnostic tools for ovine PVs are discussed.

Conclusions:

  • Ovine papillomaviruses represent an under-researched area with potential impacts on animal and public health.
  • Further dedicated research is crucial for understanding and managing ovine PV infections.
  • A comprehensive understanding of ovine PVs is essential for veterinary diagnostics and disease control.
