Description
SIN3 is a master transcriptional scaffold protein. SIN3 interacts with RPD3 and other accessory proteins to form a histone modifying complex. A single Sin3A gene encodes multiple isoforms of SIN3, of which SIN3 187 and SIN3 220 are the predominant isoforms. Previous studies demonstrated that SIN3 isoforms play non-redundant roles during fly development. In the current study, we sought to investigate the genes regulated by SIN3 187. Overall design: S2 cells and cells carrying a stable transgene of SIN3 187HA (SIN3 187HA cells) were treated with 0.07 µM CuSO4. CuSO4 treatment led to ectopic expression of SIN3 187HA. S2 cells were used as a control. Following induction, total mRNA was extracted. mRNA profiling of these samples were performed by deep sequencing using Illumina Hiseq2500. Three biological replicates were performed.

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
Primary HBE cells were stimulated with IL-22 and IL-17, and gene expression was studied using an Affymetrix platform microarray, in order to investigate which genes may be upregulated or downregulated in response to these cytokines. Of particular interest was the host defense genes such as antimicrobial peptides, which have been shown to be upregulated by IL-22 and IL-17 in skin keratinocytes.

Description
Cells constantly adapt to changes in their environment. In the majority of cases, the environment shifts between conditions that were previously encountered during the course of evolution, thus enabling evolutionary-programmed responses. In rare cases, however, cells may encounter a new environment to which a novel response is required. To characterize the first steps in adaptation to a novel condition, we studied budding yeast growth on xylulose, a sugar that is very rarely found in the wild. We previously reported that growth on xylulose induces the expression of amino-acid biosynthesis genes, in multiple natural yeast isolates. This induction occurs despite the presence of amino acids in the growth medium and is a unique response to xylulose, not triggered by any of the naturally available carbon sources tested. Propagating these strains for ~300 generations on xylulose significantly improved their growth rate. Notably, the most significant change in gene expression was the loss of amino acid biosynthesis gene induction. Furthermore, the reduction in amino-acid biosynthesis gene expression on xylulose was strongly correlated with the improvement in growth rate, suggesting that internal depletion of amino-acids presented the major bottleneck limiting growth in xylulose. We discuss the possible implications of our results for explaining how cells maintain the balance between supply and demand of amino acids during growth in evolutionary 'familiar' vs. 'novel' conditions. Overall design: mRNA profiles of 12 wt S. cerevisiae strains grown on either YPD or YP-xylulose, before and after 300 generations evolution on YP-xylulose
