Description
Experience-dependent plasticity (EDP) is essential for anatomical and functional maturation of sensory circuits during development and can be readily studied is the rodent barrel cortex. Using this model we aimed to uncover changes on the transcriptome level and applied RNA sequencing upon altered sensory experience in juvenile mice in a cortical column and layer specific manner. From column- and layer-specific barrel cortical tissue, high quality RNA was purified and sequenced. The current dataset entails an average of 50 million paired-end reads per sample, 75 base pairs in length. Overall design: Wild type mice were deprived of their C-row whiskers from P12 until P23-P24, after which acute brain slices were prepared and tissues were excised from L2/3 and L4 from specific barrel columns. RNA isolated from these tissue sections was then subjected to RNA-sequencing.

Description
Synthetic, innate defense regulators (IDR) peptides, designed based on natural host defenses peptides, have enhanced immunomodulatory activities and reduced toxicity leading to protection in infection and inflammation models that is dependent on macrophages/monocytes. Here we measured the effect of IDR-1018 on macrophage gene expression during differentiation. Differentiation in the presence of IDR-1018 induced a unique signature of immune responses suggesting that IDR-1018 drives macrophage differentiation towards an intermediate M1-M2 state, enhancing anti-inflammatory functions while maintaining certain pro-inflammatory activities important to the resolution of infection. Overall design: RNA-seq was performed using the Illumina Genome Analyzer IIx platform. Monocytes were isolated from 3 healthy donors, and left unstimulated or stimulated for 4 hours with 20 µg/ml IDR-1018. For library preparation, 500 ng of total RNA was processed according to the Illumina TruSeq RNA sample preparation guide (Illumina catalogue number FC-122-1002). Briefly, mRNA was purified using poly-dT beads, followed by synthesis of the first and second cDNA strands, end repair addition of an poly-A overhang, and ligation of adapters and unique barcodes, as per the manufacturer’s instructions. DNA enrichment was carried out via a 15-cycle PCR. Following quantification, 8 pM of dsDNA was used for cluster generation on a CBOT instrument (Illumina, San Diego, CA). RNA sequencing was done on a GAIIx instrument (Illumina), performed as a single read run with 51 amplification cycles. Data processing was carried out in house, using CASAVA to convert raw data and demultiplex to FASTQ sequence files. Reads were aligned to the reference genome using TOPHAT, and then mapped to genes using the Bioconductor package GenomeRanges.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Non-steroidal anti-inflammatory drugs, principally aspirin (acetylsalicylic acid, ASA), have anti-neoplastic properties, as shown by epidemiological studies on colorectal cancer and many other types of tumours. The chemopreventive and anti-proliferative properties of aspirin towards tumour cells have been shown to be due to the induction of programmed cell death such as apoptosis. Yeast cells are among the experimental models used extensively for the study of oxidative stress and apoptosis in living organisms because yeast, such as S. cerevisiae, retains many of the core eukaryotic cellular processes, including the hallmarks of eukaryotic apoptosis. An important contribution of our previous work has been the clarification of the critical defensive role of the antioxidant mitochondrial enzyme manganese superoxide dismutase (MnSOD) against apoptosis, confirmed to be the attenuation of aspirin-induced superoxide radical accumulation in the yeast mitochondria (Farrugia et al. (2013) FEMS Yeast Res 13, 755-768). To study the possible differential expression of gene transcripts in relation to the induction of apoptosis by aspirin, we used gene expression profiling by means of GeneChip Microarray Technology (Affymetrix). The yeast strains considered for this study included (1) the wild type strain S. cerevisiae EG103, which contains both MnSOD and cytosolic copper, zinc superoxide dismutase (CuZnSOD) and (2) the redox-compromised MnSOD-deficient S. cerevisiae EG110 strain. [This work was financed by the Malta Council for Science and Technology through the R&I Technology Development Programme (Project R&I-2015-001)].

Description
Purpose: To gain further mechanistic insight into phenotypic differences between wild type pancreatic islets and islets with loss of function of 4 Box C/D snoRNAs from the Rpl13a locus (U32a, U33, U34 and U35a). Methods:High quality total RNA (RIN = 8.5) was prepared from hand-picked islets (n = 4 mice/genotype) using TRIZOL reagent, treated with Turbo DNAse (Thermo Fisher), and used to prepare SeqPlex RNAseq libraries (Sigma). Sequencing was performed by the Washington University Genome Technology Access Center using two lanes of Illumina HiSeq 2500, 1x50. Reads were demultiplexed and trimmed, and STAR alignment and quantification analysis was carried out using the Partek Flow platform. Uniquely aligned reads were quantified to identify genes with at least a two-fold change between genotypes with p < 0.05 and FDR step-up of 0.05. Results:We observed 2-fold or greater differences in the expression of only six genes. Conclusions: Our data indicate that loss-of-function of snoRNAs from the Rpl13a locus is associated with modest changes in mRNA abundance. Overall design: Examination of murine pancreatic islet mRNA differential expression between wild type mice and mice with loss-of-function of U32a, U33, U34, and U35a snoRNAs.
