Description
NOTCH1 is mutationally activated in ~15% of cases of chronic lymphocytic leukaemia (CLL), but its role in B-cell development and leukemogenesis is not known. Here, we report that the active intracellular portion of NOTCH1 (ICN1) is detectable in ~50% of peripheral blood CLL cases lacking gene mutations. We identify a ‘NOTCH1 CLL gene expression signature’ in CLL cells, and show that this signature is significantly enriched in primary CLL cases expressing ICN1, independent of NOTCH1 mutation. NOTCH1 target genes include key regulators of B-cell proliferation, survival and signal transduction physiology. In particular, we show that MYC is a direct target of NOTCH1 via B-cell specific distal regulatory elements, thus implicating this oncogene in the pathogenesis of the disease. Overall design: RNA-Seq analysis

Description
Treatment of hematological malignancies by adoptive transfer of activated natural killer (NK) cells is limited by poor post-infusion persistence. We compared the ability of interleukin-2 (IL-2) and IL-15 to sustain human NK cell functions following cytokine withdrawal to model post-infusion performance. In contrasts to IL-2, IL-15 mediated stronger signaling through the IL-2/15 receptor complex and provided functional advantages. Genome-wide analysis of cytosolic and polysome-associated mRNA revealed cytokine dependent differential mRNA levels and translation during cytokine activation but also that most gene expression differences were primed by IL-15 and only manifested after cytokine withdrawal. IL-15 augmented mTOR signaling, which correlated with increased expression of genes related to cell metabolism and respiration. Consistently, mTOR inhibition abrogated IL-15-induced functional advantages. Moreover, mTOR-independent STAT-5 signaling contributed to improved NK cell function during cytokine activation but not following cytokine withdrawal. The superior performance of IL-15 stimulated NK cells was also observed using a clinically applicable protocol for NK cell expansion. Finally, expression of IL-15 correlated with cytolytic immune functions in patients with B cell lymphoma and favorable clinical outcome. These findings highlight the importance of mTOR regulated metabolic processes for immune cell functions and argue for implementation of IL-15 in adoptive NK cell cancer therapy. Overall design: Freshly isolated NK cells from 6 donors were activated with IL-2 or IL-15 for 48 hours, followed by cytokine withdrawal for 24 hours, resulting in four RNA samples per donor. From each sample, both the cytosolic as well as the polysomal fraction were collected. Donor 3 contains activation and post withdrawal data from two different donors due to poor RNA-quality obtained for some samples which did not allow for processing of the complete set of 6 donors (resulting in a total of 40 samples).

Description
Left ventricular mass (LVM) and cardiac gene expression are complex traits regulated by factors both intrinsic and extrinsic to the heart. To dissect the major determinants of LVM, we combined expression quantitative trait locus1 and quantitative trait transcript (QTT) analyses of the cardiac transcriptome in the rat. Using these methods and in vitro functional assays, we identified osteoglycin (Ogn) as a major candidate regulator of rat LVM, with increased Ogn protein expression associated with elevated LVM. We also applied genome-wide QTT analysis to the human heart and observed that, out of 22,000 transcripts, OGN transcript abundance had the highest correlation with LVM. We further confirmed a role for Ogn in the in vivo regulation of LVM in Ogn knockout mice. Taken together, these data implicate Ogn as a key regulator of LVM in rats, mice and humans, and suggest that Ogn modifies the hypertrophic response to extrinsic factors such as hypertension and aortic stenosis.
Publication Title
Integrated genomic approaches implicate osteoglycin (Ogn) in the regulation of left ventricular mass.

Description
Chronic liver injury triggers complications such as liver fibrosis and hepatocellular carcinoma (HCC), which are associated with alterations in distinct signaling pathways. Of particular interest is the interaction between mechanisms controlled by IKK/NEMO, the regulatory IKK subunit, and Jnk activation for directing cell death and survival. In the present study, we aimed to define the relevance of Jnk in hepatocyte-specific NEMO knockout mice (NEMOhepa), a genetic model of chronic inflammatory liver injury. We generated global Jnk1-/-/NEMOhepa and Jnk2-/-/NEMOhepa mice by crossing NEMOhepa mice with Jnk1-/- and Jnk2-/- animals, respectively, and examined the progression of chronic liver disease. Moreover, we investigated the expression of Jnk during acute liver injury, evaluated the role of Jnk1 in bone marrow-derived cells, and analyzed the expression of NEMO and pJnk in human diseased-livers. Deletion of Jnk1 significantly aggravated the progression of liver disease, exacerbating apoptosis, compensatory proliferation and carcinogenesis in NEMOhepa mice. Jnk2-/-/NEMOhepa showed increased RIP-1 and RIP-3 expression and hepatic inflammation. Jnk1 in hematopoietic cells rather than hepatocytes had an impact on the progression of chronic liver disease in NEMOhepa livers. These findings are of clinical relevance since NEMO expression was down-regulated in hepatocytes of patients with HCC whereas NEMO and pJnk were expressed in a large amount of infiltrating cells. While Jnk1 is protective in NEMOhepa-depleted hepatocytes, Jnk1 in hematopoietic cells rather than hepatocytes is a crucial driver of hepatic injury. These results elucidate the complex function of Jnk in chronic inflammatory liver disease.
Publication Title
Haematopoietic cell-derived Jnk1 is crucial for chronic inflammation and carcinogenesis in an experimental model of liver injury.
