Porcine transcriptomic data has rapidly expanded, enabling new insights into gene expression. Bioinformatics infrastructure is crucial for analyzing this vast amount of data and advancing pig genomics.

Area of Science:

  • Genomics and Bioinformatics
  • Comparative Genomics
  • Animal Science

Background:

  • Significant increase in porcine transcriptomic data over the past five years.
  • Over 623,000 porcine Expressed Sequence Tags (ESTs) available in Genbank.
  • ESTs have been instrumental in expanding pig-human comparative maps and understanding gene expression.

Purpose of the Study:

  • To review published and unpublished methods for analyzing porcine gene expression.
  • To discuss the integration of microarray platforms and bioinformatics efforts.
  • To predict future experimental possibilities with new tools, including the porcine genome sequence.

Main Methods:

  • Review of various gene expression analysis techniques: suppression subtractive hybridization, differential display, serial analysis of gene expression, EST sequence frequency, membrane arrays, and microarrays.
