Mutations in Microorganisms

1.2K
Mutations are heritable changes in an organism’s genome involving alterations in the base sequence of DNA or RNA. These changes can influence cellular processes and phenotypic traits, potentially transforming the unaltered wild type into a mutant form. Such changes, termed forward mutations, are pivotal in shaping the genetic diversity of organisms.RNA viruses exhibit the highest mutation rates due to the absence of robust proofreading mechanisms during genome replication. In contrast,...

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

Evolutionary Relationships through Genome Comparisons

5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Area of Science:

  • Virology
  • Bioinformatics
  • Computational Biology

Background:

  • Human Immunodeficiency Virus (HIV) pathogenesis is crucial for developing effective treatments.
  • HIV serves as a model for viral cellular hijacking.
  • Previous HIVToolbox facilitated visual data mining of HIV protein information.

Purpose of the Study:

  • To report improvements to HIVToolbox, introducing HIVToolbox2 with new functionalities for HIV pathogenesis research.
  • To integrate data on drug-binding sites, drug-resistance mutations, and immune epitopes.
  • To enable visual mining for hypothesis generation regarding HIV protein behavior and drug resistance.

Main Methods:

  • Development of HIVToolbox2, an enhanced web system for visual data mining of HIV-related information.
  • Integration of updated data including HIV protein sequences, structures, functional sites, and conservation.
  • Inclusion of new functionalities focused on drug-binding sites, drug-resistance mutations, and immune epitopes.

Main Results:

  • HIVToolbox2 provides an integrated, interactive view for visual data mining.
  • Analysis revealed homomultimerization of most HIV proteins, with functional sites overlapping multimerization interfaces.
  • Drug resistance mutations in HIV protease show regional localization, with subtype-specific prevalence.

Conclusions:

  • HIVToolbox2 facilitates the identification of global patterns in HIV proteins, including homomultimerization and drug resistance.
  • The tool aids in understanding the 'anatomy' of drug resistance in HIV protease.
  • HIVToolbox2 is an open-access resource for advancing HIV pathogenesis research and treatment strategies.
