Description
Scnn1b-Tg mice overexpress the beta subunit of the epithelial sodium channel (Scnn1b) in airway Club cells. The general phenotype of these mice is described in three published manuscripts (Mall et al. 2004, Nature Medicine, 10(5):487-93; Mall et al. 2008, Am J Respir Crit Care Med. 177(7):730-42; and Livraghi-Butrico et al. 2012, Physiol. Genomics 44(8):470-84. Briefly, overexpression of the Scnn1b transgene in airway Club cells leads to hyperabsorption of sodium from the airway surface liquid, dehydrated airway surface liquid and mucus, and reduced mucus clearance associated with accumulation of mucus plugs/plaques. The data provided here represents mRNA expression data from disseccted whole trachea (distal and proximal ends cut 3-4 cartliage rings below the larynx and just above the bifurcation, respectively) from male WT and Scnn1b-Tg littermates (C57Bl/6NTac background) at 4 time points [postnatal days (PND) 0, 3, 10, and 42]. PND 0 trachea are histologically normal, a tracheal mucus plug/obstruction develops around PND 3, the plug is receding to more distal airways by PND 10, and the trachea is again histologically normal by PND 42. The data from the WT mice provides a global look at mRNA changes across time, while the data from the Scnn1b-Tg line provides mRNA data that allows differential gene expression due to mucus obstruction to be queried.

The data provided here represents mRNA expression data from dissected whole trachea (distal and proximal ends were cut 3-4 cartilage rings below the larynx and just above the bifurcation, respectively) from male WT and Scnn1b-Tg littermates (C57Bl/6N Tac background) at 4 time points [postnatal days (PND) 0, 3, 10, and 42]. Histologically, PND 0 trachea are normal, a tracheal mucus plug/obstruction develops around PND 3 and typically recedes to the intrapulmonary airways after PND 10, and the trachea is again histologically normal by PND 42. The data from the WT mice provides a global look at mRNA post-natal developmental changes, while the data from the Scnn1b-Tg line provides mRNA data that allows differential gene expression due to airway mucus obstruction to be queried.

Histologically, PND 0 lungs are normal, at PND 3 the intrapulmonary airways exhibit transient and spotty Club cell necrosis, and by PND 10 airway mucus obstruction is evident in the proximal portion of the intrapulmonary main stem bronchus. At PND 42, Scnn1b-Tg lungs are charactyerized by chronic low level inflammation, with activated macrophages, neutrophilia, eosinophilia and increased incidence of bronchus-associated lymphoid tissue. The data from the WT mice provides a global look at mRNA post-natal developmental changes, while the data from the Scnn1b-transgenic line allows differential gene expression due to airway surface liquid dehydration and mucus obstruction to be queried.

Description
Live antigen-specific CD4 T cells are identified typically by tetramer staining or by staining of cytokines captured on the cell surface by bi-functional antibodies. We attempted identification of mycobacteria specific CD4 T cells using CD154 staining. In this method, splenocytes were stimulated with appropriate antigens in the presence of monensin and fluorochrome-conjugated anti-CD154 antibody. Antigen-specific cells will be stained positive for CD154. We performed microarrays with CD154 positive and negative CD4 T cells.

Description
We studied two growth phases- proliferation, and expansion in first pair of leaves in Arabidosis using two different overexpression lines of PID gene. Ectopic expression of PID lead to small rosette and leaf phenotype. Overall design: We used first pair of leaves from proliferation ( 9 DAS-days after stratification) and expansion (16 DAS) stage from wild type Col-0 ecotype, 35S::PID10, 35S::PID21. Three genotype, three biological replicates, two time points (=18 sample). Experiment repeated twice generating two reads in two lanes i.e. L001 & L002 for each sample. Results calculated after combining reads from both lanes (=18x2=36 raw files; 2 for each sample)

Description
Although gain of chromosome-5p is one of the most frequent DNA copy number imbalances in cervical squamous cell carcinoma (SCC), the genes that drive its selection remain poorly understood. In a previous cross-sectional clinical study we showed that the microRNA processor Drosha (located on chromosome-5p) demonstrates frequent copy-number gain and over-expression in cervical SCC, associated with altered microRNA profiles. Here, we have conducted gene depletion/over-expression experiments to demonstrate the functional significance of up-regulated Drosha in cervical SCC cells. Drosha depletion by RNA-interference (RNAi) produced significant, specific reductions in cell motility/invasiveness in vitro, with a silent RNAi-resistant Drosha mutation providing phenotype rescue. Unsupervised hierarchical clustering following global profiling of 319 microRNAs in eighteen cervical SCC cell line specimens generated two groups according to Drosha expression levels. Altering Drosha levels in individual SCC lines changed the group into which the cells clustered, with gene depletion effects being rescued by the RNAi-resistant mutation. Forty-five microRNAs showed significant differential expression between the groups, including four of fourteen that were differentially-expressed in association with Drosha levels in clinical samples. miR-31 up-regulation in Drosha over-expressing samples/cell lines was the highest-ranked change (by adjusted p-value) in both analyses, an observation validated by Northern blotting. These functional data support the role of Drosha as an oncogene in cervical SCC, by affecting expression of cancer-associated microRNAs that have the potential to regulate numerous protein-coding genes.

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.
