This review covers cDNA microarray technology for gene expression analysis, highlighting its application in cancer research. This powerful tool enables genome-wide profiling of thousands of genes simultaneously.

Area of Science:

  • Molecular Biology
  • Genomics
  • Cancer Research

Background:

  • Over 1,000,000 human expressed sequence tag (EST) sequences are publicly available, representing a significant portion of human genes.
  • Complementary DNA (cDNA) microarray technology leverages EST data for comprehensive gene expression analysis.
  • This technique offers a powerful approach to study gene expression patterns on a large scale.

Purpose of the Study:

  • To describe the principles of cDNA microarray technology.
  • To summarize the current literature on its application in cancer research.
  • To speculate on future directions and potential of this technology.

Main Methods:

  • Utilizes DNA probes from cDNA clones arrayed on a glass slide.
  • Interrogation with fluorescently labeled cDNA targets to detect gene expression.
