This was performed as in our previous publications (Pendergrass et al., 2012 (link)). cDNA samples were amplified and labeled using the Agilent Low Input Linear Amplification kit (Agilent Technologies, Santa Clara, CA) and were hybridized against Universal Mouse Reference (UMR) (Strategene, La Jolla, CA) to Agilent Whole Mouse Genome arrays (G4122F) (Agilent Technologies, Santa Clara, CA) in a common reference based design. Microarrays were hybridized and washed in accordance with manufacturer’s protocols and scanned using a dual laser GenePix 4000B scanner (Axon Instruments, Foster City, CA). The pixel intensities of the acquired images were then quantified using GenePix Pro 5.1 software (Axon Instruments, Foster City, CA).
