Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
MicroRNA are small non-coding RNA molecules that regulate gene expression. To investigate the role of microRNA in ITP, we performed genome-wide expression analyses of mRNA and microRNA in T-cells from ITP patients and controls. We identified 1,915 regulated genes and 22 regulated microRNA that differed between ITP patients and controls. Seventeen of the 22 regulated microRNA were linked to changes in target gene expression; 57 of these target genes were associated with the immune system, e.g. T-cell activation and regulation of immunoglobulin production. CXCL13 and IL-21 were two microRNA target genes significantly increased in ITP. We could demonstrate increased plasma levels of CXCL13 and others have reported increased plasma levels of IL-21 in ITP. Thus, regulated microRNA were significantly associated with both gene and protein expression of molecules in immunological pathways. We suggest that microRNA may be important regulatory molecules involved in the loss of tolerance in ITP.

- Illumina HumanHT-12 V4.0 expression beadchip
Description
To elucidate the KDM4B regulated transcriptomes in ER-positive breast cancer cells we assessed global gene expression changes in KDM4B-depleted MCF-7 cells by microarray analysis using the Illumina Human HT12 Version 4 BeadChip array. Differentially expressed genes were compared with KDM3A and FOXA1 regulated transcriptomes. We identified 229 genes co-regulated by all three enzymes and that co-regulated genes were involved in cell cycle processes. We identified that 53% and 48% of KDM4B-regulated genes were also regulated by KDM3A and FOXA1, with co-regulatory gene signatures being involved with estrogen response signatures and cell proliferation. We also identified that depletion of KDM3A and KDM4B together inhibits ER-target gene expression and ER-positive breast cancer cell growth more than depletion of either gene on its own.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Gene expression was compared for wild type yeast (BY4741) and yeast lacking Gal11/Med15 and Med3, or from a gal11-myc med3 strain. The gal11-myc allele shows a partial loss of function when combined with med3. Expression was analyzed for yeast grown in YPD as well as in CSM.

- Affymetrix Chicken Genome Array (chicken)
Description
The study is relevant to an understanding of the forces that lead to sex differences in the brain and other somatic tissues. Many neural and psychiatric diseases affect men and women differently, so the understanding of sex differences in brain function impacts on our understanding of why the male and female brain differ in their susceptibility to disease.

Illumina HiSeq 2500
Description
Mammalian insulin and IGF induce similar but not identical changes in gene expression downstream of their respective receptors. Signaling bias at the receptor differentiates the two similar ligands, though the precise mechanism is not entirely understood. We used Drosophila insulin-like peptides DILP2 and DILP5 to determine how similar insulin-like ligands regulate similar and distinct patterns of gene expression in S2 cells by RNA-Seq. Overall, DILP2 and DILP5 stimulate many of the same changes in gene expression. However, some genes are uniquely regulated by DILP2 or by DILP5. Shared and distinct gene targets were validated by q-RT-PCR with indepedent replicates. Some unique gene targets of DILP2 are involved in sugar metabolism, which is functionally related in vivo to DILP2 and not DILP5. We find that gene expression is largely regulated in parallel by DILP2 and DILP5 but some key unique targets may lead to differential physiological functions for the two insulin-like genes. Overall design: mRNA profiles from S2 cells treated with DILP2, DILP5 or solvent were sequenced on an Illumina HiSeq2500
