Hwan Jin, Yong E. Dunlap, Paul J. McBride, Sandra Al-Refai, Hanan R. Bushel, Pierre H. Freedman, Jonathan K-means cluster of differentially expressed genes and selected enriched Gene Ontology terms. <p>K-means clustering on the average fold-change in gene expression values was performed with K = 6 for the genes, K = 3 for the samples Euclidean distance as the similarity metric. Metal species with concentration values (µM) are presented at the top of each column. The values on the left side of the heat map denote the number of genes in each cluster, with the values in the parenthesis indicating the number of genes with unknown Gene Ontologies. Expression values, measures of significance, and corresponding Gene Ontologies for the genes and clusters presented in this Figure can be found in <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1000053#pgen.1000053.s003" target="_blank">Tables S1</a> and <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1000053#pgen.1000053.s004" target="_blank">S2</a>, respectively. The hierarchical cluster presented at the top of the heat-map was calculated using the 1,341 differentially expressed genes dataset used in the K-means clustering analysis.</p> differentially;genes;enriched;ontology 2008-04-25
