The Prostate Expression Databases (PEDB and mPEDB) offer researchers access to human and murine prostate gene expression data. These online resources facilitate the analysis of prostate gene expression profiles and aid in understanding prostate biology.

Area of Science:

  • Genomics
  • Bioinformatics
  • Molecular Biology

Background:

  • Gene expression profiling is crucial for understanding prostate function and disease.
  • Existing resources for prostate gene expression data were limited in scope and accessibility.
  • The development of comprehensive databases is essential for advancing prostate research.

Purpose of the Study:

  • To establish and enhance online databases for accessing and analyzing human and murine prostate gene expression data.
  • To provide researchers with tools for comparative analysis of gene expression across different prostate libraries.
  • To facilitate the identification of novel genes and pathways involved in prostate biology.

Main Methods:

  • Curated relational database construction for human prostate Expressed Sequence Tags (ESTs).

  • Development of a murine prostate expression database (mPEDB) to complement human data.
  • Implementation of a Virtual Expression Analysis Tool (VEAT) for graphical sequence comparisons.
  • Assembly of a non-redundant 'prostate unigene' set.
  • Expansion of search functionalities to include text-based and BLAST queries.

    • Main Results:

    • PEDB archives over 84,000 human prostate ESTs from 38 cDNA libraries.
    • Detailed library information, including tissue source and sequence abundance, is provided.
    • VEAT enables differential expression analysis across libraries.
    • mPEDB expands data accessibility to murine prostate gene expression.
    • The 'prostate unigene' set represents diverse prostate gene expression.

    Conclusions:

    • PEDB and mPEDB serve as valuable, integrated online resources for prostate gene expression research.
    • These databases enhance the ability to analyze and compare gene expression profiles in human and murine prostate.
    • The developed tools and data facilitate deeper insights into prostate biology and disease mechanisms.
