Description
The Bmi1 Polycomb protein is involved in the epigenetic repressive control of self renewal and survival of cancer initiating cells. In Chronic Myeloid Leukemia (CML), bmi1 expression increases gradually as the disease progresses from a chronic latent phase to a deadly blast crisis. We developped an inducible shRNA system to silence Bmi1 in the human K562 chronic myeloid leukemia (CML) cell line in order to identify new Bmi1-target genes.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Wine biological aging is a wine making process used to produce specific beverages in several countries in Europe, including Spain, Italy, France, and Hungary. This process involves the formation of a velum at the surface of the wine. Here, we present the first large scale comparison of all European flor strains involved in this process. We inferred the population structure of these European flor strains from their microsatellite genotype diversity and analyzed their ploidy. We show that almost all of these flor strains belong to the same cluster and are diploid, except for a few Spanish strains. Comparison of the array hybridization profile of six flor strains originating from these four countries, with that of three wine strains did not reveal any large segmental amplification. Nonetheless, some genes, including YKL221W/MCH2 and YKL222C, were amplified in the genome of four out of six flor strains. Finally, we correlated ICR1 ncRNA and FLO11 polymorphisms with flor yeast population structure, and associate the presence of wild type ICR1 and a long Flo11p with thin velum formation in a cluster of Jura strains. These results provide new insight into the diversity of flor yeast and show that combinations of different adaptive changes can lead to an increase of hydrophobicity and affect velum formation.

Description
Glucocorticoids are first-line agents for the treatment of many eosinophil-associated disorders. However, their mechanism of action in this group of disorders remains poorly understood, including the well-known clinical observation that glucocorticoids at therapeutic doses lead to profound, transient eosinopenia within hours of administration. To gain an unbiased, genome-wide view of the early transcriptional effects of glucocorticoids on human eosinophils in vivo, and torelate them to the kinetics of glucocorticoid-induced eosinopenia, RNA sequencing was performed on purified blood eosinophils obtained before and 30, 60, and 120 minutes after administration of a single dose of oral prednisone (1 mg/kg) to healthy subjects with hypereosinophilia (hypereosinophilia of unknown significance). Overall design: Three subjects with hypereosinophilia of unknown significance were each given a single dose of oral prednisone, 1 mg/kg. Whole blood was collected before and 30 minutes, 1 hour, and 2 hours after prednisone administration. Eosinophils were purified from each peripheral blood sample. Total RNA was obtained from purified eosinophils and subject to library preparation and high-throughput sequencing.

Description
The undifferentiated spermatogonial population of mouse testis is known to be functionally heterogeneous and contain both stem cells and committed progenitor cells. However, gene expression patterns marking these distinct cell fractions are poorly defined. We found that a subset of undifferentiated spermatogonia were marked by expression of a PDX1-GFP transgene but properties of these cells were unclear. Undifferentiated cells were therefore isolated from adult testes and separated according to expression of PDX1-GFP+ for gene expression analysis by RNA-seq. Our goal was to identify differentially expressed genes from PDX1-GFP+ vs PDX1-GFP- with that of known markers of stem and committed progenitor cells. Overall design: 4 independent sets of PDX1-GFP-positive and PDX1-GFP-negative undifferentiated spermatogonia were isolated by flow sorting from adult mouse testes.

Description
Sustained spermatogenesis in adult males and recovery of fertility following germ cell depletion are dependent on undifferentiated spermatogonia with self-renewal potential. We have previously demonstrated a critical cell-autonomous role for Gilz in spermatogonial stem cell maintainance and spermatogenesis. To identify genes regulated by Gilz in the male germline, we have isolated undifferentiated spermatogonial cells from tamoxifen treated Gilzflox/flox (Control) and Gilzflox/flox UBC-CreER (TAM-KO) mice that will allow identification of genes mis-expressed upon loss of GILZ. Overall design: 4 independent sets of Gilzflox/flox (Control) and Gilzflox/flox UBC-CreER (TAM-KO) undifferentiated spermatogonia were isolated by flow sorting from adult mouse testes 7 days after treatment with tamoxifen.

We extracted nascent plasma cell tumor (PCT) cells from within inflammatory granulomas (OG) isolated from intraperitoneal pristane-injected BALB/c.iMyc E mice at five different time points during tumor progression. We used laser capture micro-dissection to collect incipient PCT cells and analyzed their global gene expression on Affymetrix Mouse Genome 430A microarrays. Two independent studies were performed with different sets of mice

Description
Dnmt2 genes are highly conserved tRNA methyltransferases with biological roles in cellular stress responses. Dnmt2 has recently been implicated in transposon silencing in Drosophila but the exact molecular mechanisms are unclear. Adult Dnmt2 mutants were heat shocked and RNA sequencing was performed on visible high-molecular weight RNAs to determine the identity of up-regulated transposons. Dnmt2 mutants accumulated almost all families of transposons after heat shock, indicating a general mis-regulation of transposon silencing in Dnmt2 mutants during the stress response. Overall design: one sample, excised, electroeluted and pooled RNA of different molecular weight, Dnmt2 mutant during recovery from a single heat shock
