Area of Science:

  • Molecular Biology
  • Genomics
  • Biotechnology

Background:

  • Microarray technology, proposed nearly 15 years ago, allows for massively parallel analysis of nucleic acids.
  • Proof-of-principle studies a decade ago demonstrated high-density microarrays for genotyping, DNA sequencing, and whole-genome gene expression analysis.

Purpose of the Study:

  • To review the impact and evolving applications of microarray technology in biological research and clinical diagnostics.
  • To highlight the transition of microarrays from research tools to clinically relevant diagnostic tests.

Main Methods:

  • Review of foundational and advanced applications of microarray technology.
  • Analysis of gene polymorphisms, DNA sequences, and differential gene expression profiles.

Main Results:

  • Microarrays have significantly accelerated the acquisition of biological information, enabling non-hypothesis-driven research.
  • Applications have expanded into clinically relevant areas, including genotyping pharmacogenetic genes, resequencing tumor suppressor genes, and classifying cancers.

Conclusions:

  • Microarray technology has revolutionized biological discovery and holds substantial promise for developing novel diagnostic tests.
  • The clinical utility of microarrays is expanding, offering potential for personalized medicine and improved disease management.
