Abstract
We report the case of a 57-year-old man, who was diagnosed with B-cell acute lymphoblastic leukemia (B-ALL). His diagnostic workup identified a translocation t(3;9)(p13;p13). This is the fifth case reported to date that involved the forkhead box P1 gene (FOXP1) and paired box gene 5 (PAX5). The PAX5...

Abstract
We studied 17 MDS (11 de novo and 6 therapy related) and 3 chronic myelomonocytic leukemia (CMML) cases associated with inv(3) (q21q26.2) or t(3;3)(q21;q26.2). The de novo cases were further classified as refractory cytopenia with multilineage dysplasia (n = 8) and refractory anemia with excess blas...

Abstract
We built a dynamical model to test whether pure diffusion could account for the observed co-localization of genes within a defined subnuclear region. A simple standard Brownian motion model in two and three dimensions shows that preferential co-localization is possible for co-regulated genes without...

Abstract
We have previously shown that RAD50 is involved in mitotic nonhomologous integration but not in homologous integration. However, the role of Rad50 in nonhomologous integration has not previously been examined. In the current work, we report that the rad50∆ mutation caused a tenfold decrease in the...

Abstract
We review the available data and integrate the results with structural and biochemical studies of related enzymes to derive a model for Mot1's catalytic action consistent with the broad literature on enzymes in this family. We propose that the Mot1 ATPase domain is tethered to TBP by a flexible, spr...

Abstract
We have applied optimized sequencing and analysis strategies to test whether these potentially high-impact variants can be mapped at reasonable cost and throughput. By using a whole-genome multiplexing strategy, rearrangement breakpoints could be delineated at a fraction of the cost of standard sequ...

Abstract
We report two rare genetic aberrations in a schizophrenia patient that may act together to confer disease susceptibility. A previously unreported balanced t(9;17)(q33.2;q25.3) translocation was observed in two schizophrenia-affected members of a small family with diverse psychiatric disorders. The p...

Abstract
We showed that the t(4;9)(q21;p24) leads to a novel SEC31A-JAK2 fusion. Screening of 131 cHL cases identified 1 additional case with SEC31A-JAK2 and 2 additional cases with rearrangements involving JAK2. We demonstrated that SEC31A-JAK2 is oncogenic in vitro and acts as a constitutively activated ty...

Abstract
We here demonstrate that cell lines and a primary sample of t(17;19)-ALL expressed LMO2 at significantly higher levels than other B-precursor ALLs did. Transfection of E2A-HLF into a non-t(17;19) B-precursor ALL cell line induced LMO2 gene expression that was dependent on the DNA-binding and transac...

We show that EWS-Fli1 interacts with p53 within the nucleus in vivo. The introduction of EWS-Fli1 resulted in significant reduction of promoter activities and mRNA levels of p21 and mdm2, meanwhile it canceled p53-dependent growth suppression. In contrast, knockdown of EWS-Fli1 expression mediated b...
