Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Spinal cord injury leads to impaired motor and sensory functions. After spinal cord injury there is a an initial phase of hypo-reflexia followed by a developing hyper-reflexia, often termed spasticity. Previous studies have suggested a relationship between the reappearence of plateau potentials in motor neurons and the development of spasticity after spinalization. To understand the molecular mechanism behind this phenomenon we examined the transcriptional response of the motor neurons after spinal cord injury.

Description
We did the RNA-seq analysis to examine the global impact of Nicotinamide (NAM) on hiPSC-derived RPE transcriptome in order to better understand the mechanism of action of NAM. NAM inhibited the expression of Age related Macular degeneration (AMD) associated protein transcripts in hiPSC-derived RPE. Overall design: Seven hiPSC-RPE lines (4 AMD donors and 3 Control donors) that had been cultured with 10mM NAM or vehicle for three weeks were used for RNA extraction and RNA-seq analysis. We treated 4 AMD hiPSC-RPE and 3 Control hiPSC-RPE lines with 10mM NAM or vehicle.

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).
