1. A constraint-based method for identifying a genomic target of interest from a gene expression profiles, comprising:
- obtaining tissue sample expression data sets;
selecting a working gene-expressionset, said gene-expression set having a plurality of members defining subgroups of said tissue samples of said expression data sets, wherein said subgroups definition is a constrained definition; and
analyzing co-expression of said members gene set across said subgroups and identifying potential gene targets.

Abstract
In accordance with one aspect of the invention, a constraints-based method of analysis of gene expression data has been shown to provide a useful method for target identification in gene expression profiles. Such constraints-based methods of analysis provide useful analytical methods that focus on genes and related pathways that are likely to be important in disease progression, that is, to provide likely candidates that will serve as targets for various therapeutics.

12. A constraint-based method for analysis of gene expression profiles, comprising:
-
selecting a working gene set;
investigating expression patterns of said working gene set in a set of tissue samples;
defining cutting values to define categories of gene expression levels;
selecting constraints in order to bin said tissue samples into groups according to gene expression;
investigating the frequency of up-regulated and down-regulated genes across individual members and groups; and
forming at least one matrix which provides a basis for investigation of expression of members of said working gene set across said set of tissue samples, thereby providing at least one potential gene target. - View Dependent Claims (13, 14)
