Gene overlap analysis between the present data and previously published microarrays in pain model. a Venn diagram showing the number of common up- and down-regulated genes in our present mice model (mice-up, mice-down) and previously published rat model (rat-up, rat-down) after SNL. Only three genes were shared with the same tendency between the two microarray experiments. b The detailed information of the overlap genes that were significantly regulated in both the mice and rat spinal cord. c Venn diagram showing the overlap between gene-sets of our present data and previously published microarrays (Up-P up-regulated genes of the previous studies, Down-P down-regulated genes of the previous studies, Up-A up-regulated genes of the author’s data, Down-A down-regulated genes of the author’s data). d The detailed information of 14 up-regulated and 1 down-regulated overlapped genes between our present data and previously published microarrays.
