Significance (p-value) of Welch's t test comparing relative expression values of WT vs. KO tissues from each gene.

Asterisks show the level of significance: * for p<0.05, ** for p<0.01, and *** for p<0.001.
Genes that appear in bold were consistently and significantly upregulated in at least two tissues and were selected for subsequent assays.
Among the down-regulated genes appear those ones selected from the article: Chahrour M, Jung SY, Shaw C, Zhou X, Wong ST, Qin J, Zoghbi HY (2008) MeCP2, a key contributor to neurological disease, activates and represses transcription. Science 320:1224–1229.
