(A) A summary of the subsequent analysis for the identified 1,270 probe sets, which were found to be up-regulated in Ubp43−/− BMMs after 100 U/ml IFN-β treatment for 6, 24, or 48 hours. (B) Hierarchical clustering of 749 unique genes from 1,270 probes, which are found to be up-regulated by IFN-β in Ubp43−/− BMMs at 6, 24, or 48 hours after 100 U/ml IFN treatment. The genes are ordered by clustering tightness. Each row represents a single Affymetrix probe set. Each column represents a sample treated with 100 U/ml IFN-β for indicated time.
