DNA Microarrays02:34

DNA Microarrays

Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
Automated Microbial Diagnostics01:24

Automated Microbial Diagnostics

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...
Modern Molecular Taxonomy01:29

Modern Molecular Taxonomy

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...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Area of Science:

  • Genomics
  • Molecular Diagnostics
  • Personalized Medicine

Background:

  • Molecular diagnostics have rapidly advanced due to translational research and genomic analysis technologies.
  • Interpreting vast genomic data remains challenging for clinical applications.
  • Patient phenotypes are influenced by gene interactions (monogenic diseases), gene-environment interactions (multigenic diseases), and genetic variations affecting drug/nutrient responses.

Purpose of the Study:

  • To explore the concept of personalized medicine driven by individual genetic uniqueness.
  • To highlight the role of gene expression regulation in human phenotype and disease.
  • To underscore the opportunity for laboratory medicine to center patient care through molecular genetics.

Main Methods:

  • Analysis of human genome data, including gene interactions and expression patterns.
  • Investigation of epigenetic mechanisms like DNA methylation and microRNA regulation.
  • Examination of genetic influences on complex traits and behaviors.

Main Results:

  • Human phenotype complexity arises from gene expression regulation, not just gene number.
  • Altered DNA methylation is linked to cancers and potentially behaviors like suicide.
  • MicroRNA dysregulation is implicated in various human diseases.

Conclusions:

  • Chip-wide genome analysis is increasingly accessible.
  • Understanding molecular genetics confirms individual genome uniqueness.
  • Laboratory medicine can leverage this understanding to prioritize patient-centered care.
