Figure 2.

Distribution of changes in RP transcript expression caused by long-term exposure to NGF. Changes in expression are expressed as fold up- or down-regulation by NGF. Up-regulated transcripts are given as the ratio of normalized tag numbers +NGF/-NGF and are expressed as positive values. Transcripts that are down-regulated by NGF are given as the ratio of normalized tag numbers -NGF/+NGF and are expressed as negative values.
