Gene expression profiling in psoriatic lesional and non-lesional skin [brodalumab treatment]

From each of the 25 psoriasis patients, we obtained two pre-dose biopsies, one from a lesion and the other from non-lesional skin in the same general body geography, and two post-dose biopsies. Total RNA was extracted from 6mm punch biopsies that were split in half. A total of 99 samples were run on Affymetrix HU133 Plus 2.0 microarrays. There was no paired non-lesional sample for 'T_lesional_pre-dose' (skn55789).
