Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
p21 (CDKN1A) expression from an IPTG-inducible promoter in HT1080 p21-9 cells was previously shown to inhibit a set of genes, many of which are involved in cell cycle progression, and to upregulate another set of genes, some of which have been implicated in cancer and age-related diseases. We have now developed Senexin A, a small-molecule inhibitor of p21-induced transcription, which we found to be a selective inhibitor of CDK8 and CDK19. Here we tested the effect of Senexin A on the induction and inhibition of transcription by p21.

Description
We measured gene expression of D. melanogaster female heads and abdomens after mating with males from six populations evolved under either enforced monogamy (no male-male competition, 3 populations) or sustained polygamy (intense male-male competition, 3 populations). Overall design: Three samples of virgin female heads and six samples of mated female heads (one each per male evolved population, of which there are three monogamous and three polygamous), for nine libraries. Also, three samples of virgin female abdomens and six samples of mated female abdomens (one each per male evolved population, of which there are three monogamous and three polygamous), for nine libraries. In total, eighteen libraries sequenced in 8 lanes.

Description
In order to examine the consequences of Myc and Lin-28B induction on the transcriptome, P493-6 cells (human EBV-transformed B lymphocytes) were infected with a retrovirus that produces human Lin-28B or empty virus as a control. Gene expression profiles were then monitored in the high and low Myc state using Affymetrix microarrays.
Publication Title
Lin-28B transactivation is necessary for Myc-mediated let-7 repression and proliferation.

Description
Peripheral T-cell lymphoma unspecified (PTCL/U), the most common form of PTCL, displays heterogeneous morphology and phenotype, poor response to treatment, and dismal prognosis. We demonstrate that PTCL/U shows a gene expression profile clearly distinct from that of normal T-cells. Comparison with the profiles of purified T-cell subpopulations [CD4+, CD8+, resting (HLA-DR-), and activated (HLA-DR+)] reveals that PTCLs/U are most closely related to activated peripheral T-lymphocytes, either CD4+ or CD8+. Interestingly, the global gene expression profile cannot be surrogated by routine CD4/CD8 immunohistochemistry. When compared with normal T-cells, PTCLs/U display deregulation of functional programs often involved in tumorigenesis (e.g. apoptosis, proliferation, cell adhesion, and matrix remodeling). Products of deregulated genes can be detected in PTCLs/U by immunohistochemistry with an ectopic, paraphysiologic or stromal location. Among others, PTCLs/U aberrantly express PDGFRA, a tyrosine-kinase receptor, whose deregulation is often related to a malignant phenotype. Notably, both phosphorylation of PDGFRA and sensitivity of cultured PTCL cells to imatinib (as well as to an inhibitor of histone-deacetylase) are found. These results, which might be extended to other rarer PTCL categories, are provided with implications for tumor pathogenesis and clinical management.

Description
To understand the differentiation of effector Tregs in more detail, we have performed transcriptional profiling of central Tregs and effector Tregs, based on Blimp1 expression. We performed RNA-sequencing of Foxp3+ regulatory T cells, comparing Blimp1/GFP+ and Blimp1/GFP- cells Overall design: Three biologically independent samples for each condition were sequenced (condition 1: CD4+ CD25high Blimp1/GFP+; condition 2: CD4+ CD25high Blimp1/GFP-); cells were sorted from pooled spleens and lymphnodes of Blimp1/GFP reporter mice
