Description
Natural killer T (NKT) cells have immune stimulatory or inhibitory effects on the immune response that are context-dependent. This may be attributed in part to the existence of functional NKT cell subsets; however, these functional subsets have only been characterized on the basis of differential expression of a few transcription factors and cell surface molecules. Here we have analyzed purified populations of thymic NKT cell subsets at both the transcriptomic and epigenomic levels, and by single-cell RNA sequencing. Our data indicate that despite their similar antigen specificity, the functional NKT cell subsets are highly divergent populations characterized by many gene expression and epigenetic differences. Therefore the thymus imprints innate-like NKT cells with novel combinations of properties, including differences in proliferative capacity, homing, and effector functions that were not previously anticipated. Overall design: Analysis of single cell transcriptomic heterogeneity in mouse Va14 iNKT thymocyte subsets (NKT1, NKT2, NKT17 and NKT0). Samples were generated from individual experiment using a pool of thymocytes prepared from five five-week old C57BL/6J females. NKT cells subtypes were isolated from thymuses and directly sorted by flow cytometry into lysis buffer (96 well plate single cell sort). The preparation of samples occurred in 2 different batches (both having a equal representation of the different cell populations).

Affymetrix Rat Expression 230A Array (rae230a), Affymetrix Rat Expression 230B Array (rae230b)
Description
5 strains of rat, WKY, spontaneously hypertensive rat (SHR) and 3 reciprocal congenic strains (WconSA, SconSA and SISA) were used to generate expression data across the genome using the Affymetrix rat genome chip set comprising the 230 A and 230 B chips. 5 animals from each strain were used. Expression data was determined for 2 ages: 6 week and 24 week with whole kidney RNA.

Description
IMP3 (IGF2-mRNA binding protein 3) is a member of a family of IGF2-mRNA binding proteins that function in RNA stabilization, trafficking and localization. It exhibits the properties of an oncofetal protein and its expression correlates with the aggressive behavior of many tumors. In breast cancer, IMP3 is associated with the highly aggressive triple-negative subtype (TNBC) The challenge is to identify specific proteins and functions that are regulated by IMP3. As an approach to this problem, we compared the mRNA expression profile of SUM-1315 cells, a TNBC cell line, to the same cells that had been depleted of IMP3. Overall design: SUM-1315 breast cancer cells were were infected with lentivirus for control shRNA and two different IMP3 shRNAs and processed for RNA-sequencing

- Affymetrix Human Gene 2.0 ST Array (hugene20st)
Description
CHOPS syndrome is caused by germline gain-of-function mutations of AFF4. Cornelia de Lange syndrome is caused by germline mutations of cohesin loading factors or cohesin complex genes such as NIPBL, SMC1A, SMC3 and HDAC8. There are many overlapping clinical features exist between CHOPS syndrome and Cornelia de Lange syndrome. To identified commonly dysregulated genes in CHOPS syndrome and Cornelia de Lange syndrome, we perfomred side-by-side transcriptome comparison between CHOPS syndrome and Cornelia de Lange syndrome.

Description
AFF4 is a component of super elongation complex (SEC), which plays an important role in mobilizing paused RNA polymerase II at gene promoter regions. Using exome sequenging, we have identified a novel genetic disorder caused by missense mutations in AFF4. We propose CHOPS syndrome as a name for this new diagnosis. To evaluate the effect of identified missense mutations of AFF4, utilizing patient derived skin fibroblast cell lines, the gene expression analysis was perfomred.

Description
Chronic injury in kidney transplants remains a major cause of graft loss. The aim of this study was to identify a predictive gene set capable of classifying renal grafts at risk for progressive injury due to fibrosis.The Genomics of Chronic Allograft Rejection (GoCAR) study is a prospective, multicenter study. Biopsies obtained prospectively 3 months after transplantation from renal allograft recipients (n=159) with stable renal function were analyzed for gene expression by microarray. Genes were sought which correlated with subsequent 12-month Chronic Allograft Damage Index (CADI) but neither CADI in the 3 month biopsy nor other histological or clinical parameters.

Description
The goal of this study was to compare mRNA from mammary epithelial cells of 3 mammary-specific Nmi knockout FVB with corresponding wildtype control. This was performed to obtain clues to the signaling pathways that were impacted in the mammary epithelial cells upon knocking-out Nmi expression. Overall design: To determine how the loss of Nmi contributed to a hyper-proliferative phenotype during puberty and lactation, we performed global RNAseq analysis from enriched mammary epithelial organoids from lactation day1 (L1), the time when Nmi protein expression in normal mammary epithelium is at its highest level. We compared 2 groups with 3 mice/group. We used second and third mammary glands of each mouse. These glands were isolated from mice on the first day of lactation, minced and dissociated in digestion medium (HBSS containing collagenase I (Sigma Aldrich, St. Louis, MO) (1mg/mL) and Pronase (Sigma Aldrich) (0.1mg/mL)) for two hours at 37C with shaking. Epithelial organoids were washed in PBS and enriched by pulse centrifugation to 1500rpm at least three times before subsequent assays.

- Affymetrix Maize Genome Array (maize)
Description
The hemibiotrophic fungal pathogen Colletotrichum graminicola is the causal agent of anthracnose disease on maize stalks and leaves. After the formation of appressoria the host cell wall is penetrated by the conversion of appressorial turgor pressure into forceful ejection of a penetration peg. Subsequently, C. graminicola establishes biotrophic hyphae in the penetrated epidermis cell at around 36 hours post inoculation (hpi) until a switch of hyphal morphology and lifestyle takes place during the colonization of neighboring host cells at around 72 hpi. During the ensuing necrotrophic growth, dark necrotic lesions are formed that are visible as anthracnose symptoms. We used microarrays to detail the global programme of gene expression during the infection process of Colletotrichum graminicola in its host plant to get insight into the defense response of this compatible interaction and into the metabolic reprogramming needed to supply the fungus with nutrients.
