Gene Ontology analysis of genes found to be misregulated in the microarray analysis of ron1-1. A, Analysis of 371 up-regulated genes. B, Analysis of 263 down-regulated genes. The yellow to orange color of the circles indicates the significance level for each overrepresented Gene Ontology category, from 0.05 and below, according to a multiple t test with a false discovery rate-corrected P value. Circle sizes are proportional to the number of genes in the category.
