Description
The bromodomain and extraterminal (BET) protein BRD4 is a therapeutic target in acute myeloid leukemia (AML). Here, we demonstrate that the AML maintenance function of BRD4 requires its interaction with NSD3, which belongs to a subfamily of H3K36 methyltransferases. Unexpectedly, AML cells were found to only require a short isoform of NSD3 that lacks the methyltransferase domain. We show that NSD3-short is an adaptor protein that sustains leukemia by linking BRD4 to the CHD8 chromatin remodeler, by using a PWWP chromatin reader module, and by employing an acidic transactivation domain. Genetic targeting of NSD3 or CHD8 mimics the phenotypic and transcriptional effects of BRD4 inhibition. Furthermore, BRD4, NSD3, and CHD8 colocalize across the AML genome, and each is released from super-enhancer regions upon chemical inhibition of BET bromodomains. These findings suggest that BET inhibitors exert therapeutic effects in leukemia by evicting BRD4-NSD3-CHD8 complexes from chromatin to suppress transcription. Overall design: PolyA+ (illumine TruSeq)/not-so-random (NSR) primers selected RNA-Seq for shRNA/sgRNA-expressing MLL-AF9 transformed acute myeloid leukemia cells (RN2).

Description
Individuals with the ALS-linked (amyotrophic lateral sclerosis) truncation mutation (R495X) in FUS (fused in sarcoma) are known to have a more aggressive form of the disease than those with point mutations. The underlying cause for this difference is unclear. We report that FUS is a component of miRISC (miRNA-induced silencing complex) and that overexpression of its truncation mutant R495X negatively impacts miRNA mediated RNA silencing.

Description
T cells contribute to host-tumor interactions in patients with monoclonal gammopathies. Expansions of CD8+CD57+TCRV+ restricted cytotoxic T cell (CTL) clones are found in 48% of patients with multiple myeloma and confer a favorable prognosis. We now report the presence of CTL clones with varying TCRV repertoire in 70% of patients with Waldenstroms Macroglobulinaemia (WM) (n=20). Previous nucleoside analogue (NA) therapy, associated with an increased incidence of transformation to aggressive lymphoma, significantly influenced the presence of TCRV expansions (X2=11.6; P<0.001) as 83% of patients without (n=6) and only 7% with TCRV expansions (n=14) had received NA. Clonality of CD3+CD8+CD57+TCRV+ restricted CTLs were confirmed by TCRV CDR3 size analysis and direct sequencing. To characterize CTL clones, samples of CD3+CD8+CD57+TCRV+ cells were profiled using DNA microarrays and the results were validated on both gene and protein level. By gene set enrichment analysis, CTL clones not only expressed genes (GZMB, PRF1, FGFBP2) from cytotoxic pathways but also genes which suppress apoptosis, inhibit proliferation, arrest cell cycle G1/S transition and activate T cells (RAS, CSK and TOB pathways). Proliferation tracking confirmed their anergic state. Our studies demonstrate the incidence, NA sensitivity and anergic nature of clonal T cells in a B cell tumor.
Publication Title
Clonal expansions of cytotoxic T cells exist in the blood of patients with Waldenstrom macroglobulinemia but exhibit anergic properties and are eliminated by nucleoside analogue therapy.

Description
Developmentally synchronized animals were obtained by hypochlorite treatment of gravid adults to release embryos. Synchronized embryos were hatched on NGM plates and grown at 20°C until 48 h after the L4 stage of development. Fluorodeoxyuridine was used to prevent the development of second-generation embryos once animals reached fertile adulthood. For each RNA-seq experiment, populations for odIs77[Pcol-19::UbG76V-GFP] and dop-1(vs100); [Pcol- 19::UbG76V-GFP] were grown simultaneously under the same conditions. Total RNA was isolated from animals using trizol (Invitrogen) combined with Bead Beater lysis in 3 biological replicates, and an mRNA library (single-end, 50-bp reads) was prepared for each sample/replicate using Illumina Truseq with PolyA selection. Overall design: Examination of mRNA levels in adults dop-1 mutants and wild-type animals.

Description
The HT29 derivative cell line HT29-MTX-E12 (E12) produces an adherent mucus layer predominantly of the gastric MUC5AC mucin when grown on transwells. This mucus layer supports Helicobacter pylori survival in culture. E12 cells were infected with H. pylori and the transcriptome of infected and uninfected E12 were compared. Also included for comparison was the HT29 parent cell line grown on transwells.
