Gene expression Grade Index (GGI) as published in Sotiriou et al. 2006
List of 128 affymetrix hgu133a probesets representing 97 unique genes included in the GGI signature. The "EntrezGene.ID" column allows for mapping and "grade" defines the up-regulation of the expressions either in histological grade 1 or 3.
sig.ggi is a matrix with 9 columns containing the annotations and information related to the signature itself.
