Apoptosis map. Expression data of Rhok^−/−/Sag^−/− mice was overlaid onto a hypothetical apoptosis map using the GenMAPP (http://www.genmapp.org) program. Each rectangle represents a gene in the pathway. The number on the right of the rectangle corresponds to the log ₂ ratio. Genes highlighted in yellow are unchanged. Pink and red denote upregulated genes while dark and light green correspond to downregulated genes. Rhok^−/−/Sag^−/− mice were exposed to 1 hour of low light (450 lux) and adapted for the indicated time period of darkness.
