Choosing the right path: enhancement of biologically relevant sets of genes or proteins using pathway structure

Genome Biol. 2009;10(4):R44. doi: 10.1186/gb-2009-10-4-r44. Epub 2009 Apr 24.


A method is proposed that finds enriched pathways relevant to a studied condition using the measured molecular data and also the structural information of the pathway viewed as a network of nodes and edges. Tests are performed using simulated data and genomic data sets and the method is compared to two existing approaches. The analysis provided demonstrates the method proposed is very competitive with the current approaches and also provides biologically relevant results.
