Gene expression omnibus: microarray data storage, submission, retrieval, and analysis.

abstract：:The Omega class of cytosolic glutathione transferases was initially recognized by bioinformatic analysis of human sequence databases, and orthologous sequences were subsequently discovered in mouse, rat, pig, Caenorhabditis elegans, Schistosoma mansoni, and Drosophila melanogaster. In humans and mice, two GSTO genes h...
