Table 1.

Ten genes that have expression profiles most similar to diazepam binding inibitor, DBI, in two large-scale microarray expression profiling studies, as quantified by Pearson correlation coefficient r (the top 10 neighbors of DBI are shown for each sample set, corresponding to r > 0.73 for the fibroblast samples). Genes that are mentioned twice refer to two independent clones on the array.

Bold genes are involved in lipid metabolism. The expression profiles can be explored and compared at http://genome-www.stanford.edu/fibroblast/figures.shtml (fibroblast samples) and http://genome-www5.stanford.edu/cgi-bin/source/sourceSearch (carcinoma samples).
