BL subtypes present with differences in their GEPs. (A) Supervised approach identified 222 probe sets differentially expressed in eBL versus sBL versus HIV-BL (Kruskal-Wallis test). (B) The corresponding genes belonged to relevant functional categories, including cell cycle regulation, nucleic acid metabolism, proliferation, and transcription. (C) Supervised analysis of eBL versus sBL identified 129 genes differentially expressed.
