Transcriptome of congenic mice with transient inflammatory arthritis: resque of C5 complement deficiency

Abstract

We found that Pgis2-congenic mice that carry genetically-deficient copy of C5(Hc) complement component were susceptible to collagen antibody-induced arthritis while inflammation was transient. Using differential gene expression analysis tools, we identified 20 genes whose down/up regulation in Pgis2-congenic mice might rescue C5 complement deficiency or, in a wider sense, rescue the function of the entire Pgis2 locus.
