Peripheral T-cell lymphoma cell line T8ML-1 highlights conspicuous targeting of PVRL2 by t(14;19)(q11.2;q13.3).

Abstract

Focal amplifications and chromosome translocations involving the long arm of chromosome 19 (19q13.3) are recurrent in T-cell lymphoma, where neighboring BCL3 and PVRL2 are competing target genes. Here we present the oncogenomic characterization of a peripheral T-cell lymphoma (PTCL) cell line T8ML-1 to reveal t(14;19)(q11.2;q13.3) juxtaposing TRA@ and PVRL2. Parallel mRNA and protein expression data for the 19q13.3 region of interest pinpointed PVRL2 as the sole conspicuous target therein. Collectively, our findings endorse T8ML-1 as the first proven cell line model for t(14;19)/PTCL.
