Patients undergo blood sample collection periodically for correlative studies. Samples are analyzed for the effects of bortezomib on viral activation and replication via Taqman polymerase chain reaction (PCR), and for quantification of APOBEC3G levels via western blot. Similar studies are performed on the BCLB-1 EBV containing lines, as well as Daudi and other EBV-transformed B-lymphocyte lines via quantitative viral DNA PCR.
