Description
We have previously demonstrated that bone marrow-derived DC can prevent diabetes development and halt progression of insulitis in NOD mice, the mouse model of type 1 diabetes (T1D). The DC population that was most effective in this therapy had a mature phenotype, expressed high levels of costimulatory molecules and secreted low levels of IL-12p70. The protective DC therapy induced regulatory Th2 cells that shifted the dominant Th1 environment, present in NOD mice, to a mixed Th1/Th2 milieu. Microarray analysis of therapeutic and non-therapeutic DC populations revealed several novel molecules that could play important roles in the observed DC-mediated therapy. The therapeutic DC population expressed a unique pattern of costimulatory molecules and chemokines, which were confirmed by flow cytometry and ELISA assays. We have performed in vitro chemotaxis assays that demonstrated the therapeutic DC preferentially attracted Th2 cells, as compared to Th1, Treg or nave T cells. In addition we quantified the in vivo migration of activated islet-specific T cells to the pancreas using novel cell labeling techniques and 19F nuclear magnetic resonance. A subcutaenous injection of therapeutic DC alters the migration of both Th1 and Th2 cells to the pancreas, and Th1 cells appeared in the lymph node draining the site of DC injection. These results suggest that the therapeutic function of DC is mediated in part by the chemoattractive properties of these DC for diabetogenic Th1 cells.

Description
cdipt is an essential gene in the synthesis of phosphatidylinositol (PtdIns) in the zebrafish, Danio rerio. The zebrafish mutant cdipt^hi559Tg (ZL782) carries a retroviral insertion which inactivates cdipt. Homozygous mutants exhibit hepatocellular endoplasmic reticulum (ER) stress and non-alcoholic fatty liver disease (NAFLD) pathologies at 5 days post fertilization (dpf). This study reveals a novel link between PtdIns, ER stress, and steatosis.

Description
Messenger RNA is thought to predominantly reside in the cytoplasm, where it is translated and eventually degraded. Although nuclear retention of mRNA has a regulatory potential it is considered extremely rare in mammals. Here to explore the extent of mRNA retention in metabolic tissues we combine deep sequencing of nuclear and cytoplasmic RNA fractions with single molecule transcript imaging in mouse beta cells, liver and gut. We identify a wide range of protein coding genes for which the levels of spliced polyadenylated mRNA are higher in the nucleus than in the cytoplasm. These include genes such as the transcription factor ChREBP, Nlrp6, Glucokinase and Glucagon receptor. We demonstrate that nuclear retention of mRNA can efficiently buffer cytoplasmic transcript levels from noise that emanates from transcriptional bursts. Our study challenges the view that transcripts predominantly reside in the cytoplasm and reveals a role of the nucleus in dampening gene expression noise. Overall design: we have total of 8 samples all are mice. liver nuclear RNA (2 replicates), liver cytoplasmic RNA (2 replicates), MIN6 (cell line) nuclear RNA (2 replicates), MIN6 (cell line) cytoplasmic RNA (2 replicates)

Description
A non-controversial and non-invasive source of adult stem cells (ASCs), particularly hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) is human umbilical cord blood. HSCs derived from cord blood have been used for treating leukemia and other blood disorders for the last 30 years. While the presence of MSCs in cord blood is limited, umbilical cord has been found to be promising source of MSCs. However, the cord is an anatomically complex organ and potential isolation of MSCs from its various parts has not been fully explored.

- Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
Experiments were designed to evaluate changes in the transcriptome (mRNA levels) in the ovulatory, luteinizing follicle of rhesus monkeys, using a controlled ovulation (COv) model that permits analysis of the naturally selected, dominant follicle at specific intervals (0, 12, 24, 36 hours) after exposure to an ovulatory (exogenous hCG) stimulus during the menstrual cycle. Total RNA was prepared from individual follicles (n=4-8/timepoint), with an aliquot used for microarray analysis (AffymetrixTM Rhesus Macaque Genome Array) and the remainder applied to quantitative real-time PCR (q-PCR) assays. The microarray data from individual samples distinctly clustered according to timepoints, and ovulated follicles displayed markedly different expression patterns from unruptured follicles at 36 h. Between timepoint comparisons revealed profound changes in mRNA expression profiles. The dynamic pattern of mRNA expression for steroidogenic enzymes (CYP17A, CYP19A, HSD3B2, HSD11B1, HSD11B2), StAR, and gonadotropin receptors (LHCGR, FSHR) as determined by microarray analysis correlated precisely with those from blinded q-PCR assays. Patterns of mRNA expression for EGF-like factors (AREG, EREG) and processes (HAS2, TNFAIP6) implicated in cumulus-oocyte maturation/expansion were also comparable between assays. Thus, several mRNAs displayed the expected expression pattern for purported theca (e.g., CYP17A, AREG), granulosa (CYP19A, FSHR), cumulus (HAS2, TNFAIP6) cell, and surface epithelium (HSD11B) related genes in the rodent/primate preovulatory follicle. This database will be of great value in analyzing molecular and cellular pathways associated with periovulatory events in the primate follicle (e.g. follicle rupture, luteinization, inflammatory response, and angiogenesis), and for identifying novel gene products controlling mammalian fertility.

Description
Overexpression of miR-155 in hematological tissue leads to the onset of lymphoma, and Tet-off shutdown of this overexpression reverses the disease phenotype in mir-155LSLtTA mice. This study compares the gene expression profiles of tumors with miR-155 overexpression and withdrawal. Overall design: Examination of mRNA from 2 conditions: miR-155 overexpressing tumors and miR-155 overexpressing tumors from mice exposed to doxycycline (DOX) for 16hrs prior to harvest; samples in triplicate; tumors generated in flanks of nude mice by subcutaneous injection of splenic cells from diseased mir-155LSLtTA mice.
