Additional data file 1:

Word file listing 77 genes (including 14 genes with yet unknown functions) expressed differently at significant levels in spleen cells of naive and proteoglycan-immunized (non-arthritic) mice of BALB/cJ and BALB/cByJ colonies (as shown in Fig 2 as hierarchical clusterization). Four-group cross-comparison were used: naive BALB/cJ vs. immunized BALB/cJ, naive BALB/cByJ vs. immunized BALB/cByJ, naive BALB/cJ vs. naïve BALB/cByJ and immunized BALB/cJ vs. immunized BALB/cByJ). This file contains probe set identification numbers (Affymetrix), gene symbols, names and their chromosome localization, Ensembl numbers, p values, and brief description of gene function (if known). Genes with unknown functions are highlighted in blue, and genes having immuno-regulatory function in yellow. The corresponding references of these immuno-regulatory genes are [30-65]. Original data (.cel) files are submitted to Gene Expression Omnibus (Accession Number [GEO:GSE13730]; NCBI tracking system number 15549466).
