Expression of wild-type MOZ and TIF2. (A) RNA from EBV-LEUK1 and normal peripheral blood mononuclear cells was analyzed by RT-PCR. A PCR product containing the MOZ breakpoint was amplified when MOZ 3303F was paired with either MOZ 3784R (lanes 1 and 3) or MOZ 3880R (lanes 2 and 4). (B) TIF2 primers that flank the TIF2 breakpoint amplify products of 1,315 and 1,105 bp from EBV-LEUK1 cDNA, corresponding to the alternatively spliced forms of TIF2 cDNA. M1 and M2 indicate 100-bp marker ladders and λ-BstE 2 DNA size markers, respectively.
