dGenes annotated with GeneBase 260
  1. acDNA probes remaining after quality control check for removal of any that were undetectable, below background, malformed, had saturated pixel intensity, or were not present on at least half of the microarray slides
  2. bcDNA probes with detectable background-corrected signal on at least 16 microarray slides and significantly different at P ≤ 0.05
  3. ccDNA probes with detectable background-corrected signal on at least 16 microarray slides, P ≤ 0.05 for line-by-age interaction or main effect of line, and a difference between groups of 1.6-fold or greater (0.68-fold on a log2-scale)
  4. dNumber of 291 differentially expressed genes successfully annotated with protein identifiers using the GeneBase tool at http://cogburn.dbi.udel.edu/
