%0 Journal Article %T The genomic 'inner fish' and a regulatory enigma in the vertebrates %A Malone John %A Oliver Brian %J Journal of Biology %D 2009 %I %R 10.1186/jbiol131 %X Information on how genomic information from fish to human encodes the same tissues has until now emerged one gene at a time. The study published in this issue now provides lists of genes and their expression levels for 20 vertebrate tissues spanning 450 million years of vertebrate evolution. It reveals a core set of genes with similar tissue-expression patterns yet no common regulatory signatures ¨C a gene-expression paradox. %U http://jbiol.com/content/8/3/32
