The number of DEGs in the corresponding pathway is shown. Expected counts from a random distribution based on the statistical analysis described by Nemhauser et al. (2006) are shown in parenthesis. The p-value was calculated using Fisher's Exact Test. Numbers significantly different to controls are shown in bold.
