  1. aOnly genes having gene expression data are shown here. Thus, the number of IL genes in this table is smaller than the total number of detected IL genes. bTotal number of housekeeping genes: mice, 972; rats, 178. cFisher's exact test was used to calculate the values of P. IL: intron-lost; NIL: no-intron-lost.
