GO ontology analysis of epicardial signature genes.

Epicardial GO ontology list included various innate immune system lists as well as the cell adhesion list, confirming the epithelial character of the epicardium. An FDR cut off of 0.0005 was used. (q: number of epicardial genes present in the given GO list; m: total number of genes in a given GO list; p: FDR value for a given GO list enrichment among the epicardial genes).
