BBC3 and thymoma: While key apoptosis-related gens like BCL2, MCL1, BIRC2, BIRC5, BCL2L1 were represented but did not show differential expression between TSCC and B3 thymomas (not shown), other important genes (e.g., BIRC4/XIAP, BIRC6-8, BAX, BBC3/PUMA, and BIM) were missing and warrant further analysis.
