A. PAR1-dependent genes. Inflammation was induced by intravesical instillation of substance P or LPS into the bladder of WT and PAR1-/- mice and compared to control (saline-treated); see methods for details. Twenty-four hours after, bladders were removed and the RNA was isolated for cDNA array experiments. Genes that were upregulated in response to inflammation in wild type mice and failed to be up-regulated in PAR1-/- mice were considered to be PAR-1 dependent transcripts. PAR-1 dependent transcripts were used to query the Ingenuity Pathways Analysis [IPA] and based on EntrezGene and Gene Ontology annotations were distributed into relevant biological compartments and biological interactions.
