Next Generation Sequencing of Wild Type and Glis3 Mutant Fetal Testis Transcriptomes
  • organism-icon Mus musculus
  • sample-icon 14 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2500

Description

The goals of this study are to utilize high-throughput transcriptome sequencing of mutant and control fetal testis samples to identify changes in both transcript and repeat element abundance in tissues harboring a homozygous mutation for Glis3. 672 unique genes were differentially expressed in mutant versus wild-type samples. Of the downregulated genes, there was a strong enrichment for piRNA pathway members, while upregulated genes were associated with leydig cell differentiation, meiosis, and histone cluster genes. Differential expression of several repeat elements was also detected in mutant samples. Our findings provide valuable information on the potential mechanisms underlying the fetal germ cell loss observed in Glis3 mutant testes. Overall design: Whole testis mRNA profiles of embryonic day 14.5 wild type (WT) and Glis3 mutant mice were generated by deep sequencing, using Illumina HiSeq2500

Immunologic Control of Zika Virus in Rhesus Monkeys
  • organism-icon Macaca mulatta
  • sample-icon 46 Downloadable Samples
  • Technology Badge Icon Rhesus Gene 1.0 ST Array (rhegene10st)

Description

Zika virus (ZIKV) is responsible for a major current outbreak in the Americas and has been causally associated with fetal microcephaly as well as Guillain-Barre syndrome in adults. However, the immune responses associated with controlling ZIKV replication remain poorly characterized. Here we report a detailed analysis of innate and adaptive immune responses following ZIKV infection in 16 rhesus monkeys. A robust proinflammatory innate immune response was observed within the first few days of infection, including upregulation of type 1 interferon, which correlated directly with viral loads. Immunomodulatory pathways, including IL-10 and TGF-, were also upregulated. ZIKV-specific neutralizing antibodies emerged rapidly by day 7 and correlated inversely with viral loads, which were undetectable in peripheral blood by day 6-10. In contrast, virus replication persisted in cerebrospinal fluid (CSF) for at least 21-42 days in 75% (3 of 4) of the monkeys that received the lowest dose of ZIKV tested, and ZIKV-specific antibodies were essentially undetectable in CSF. These data suggest that antibodies play a critical role in the rapid control of acute viremia in the periphery but were largely excluded from the central nervous system, allowing viral persistence at this immuonoprivileged site.

T.F. Glis3: a novel critical player in the regulation of pancreatic beta-cell development and insulin gene expression
  • organism-icon Mus musculus
  • sample-icon 7 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Genome 430 2.0 Array (mouse4302)

Description

Glis3 mutant mice (Glis3zf/zf) die within the first week after birth due to overt diabetes, evidenced by hyperglycemia and hypoinsulinemia. Histopathological analysis showed that Glis3zf/zf mice develop a pancreatic phenotype with a dramatic loss of beta- (insulin) and delta- (somatostatin) cells contrasting a smaller relative loss of alpha- (glucagon), PP- (pancreatic polypeptide), and epsilon- (ghrelin) cells. Glis3zf/zf mice develop ductal cysts with decreased number of primary cilia, while the acini are not significantly affected. Gene expression profiling by microarray analysis demonstrated that the expression of terminal hormonal genes and several transcription factors important in endocrine development were significantly deregulated in Glis3zf/zf mice. During pancreatic development, Glis3 mRNA expression is induced during the secondary transition, a stage of cell lineage specification and extensive patterning. Changes in pancreatic development of Glis3zf/zf mice are noted during and after this stage. The population of pancreatic progenitors appears not to be greatly affected in Glis3zf/zf mice; however, the number of neurogenin 3 (Ngn3) positive, endocrine progenitors is significantly reduced. Our study indicates that Glis3 plays a key role in cell lineage specification, particularly the development of mature pancreatic beta-cells. In addition, we identified evidence that Glis3 regulates insulin gene expression through two Glis-binding sites in its proximal promoter indicating that Glis3 is a regulator of insulin gene expression.

Orthopox viruses, including monkeypox, multiply intracellularly and induce numerous changes in host genes expression. The virus target mainly humoral host response, and simultaneously, exploits other genes and functions to reproduce effectively. The goal of this experiment is to identify those host genes and functions that are essential for monkeypox virus replication.

Transcriptome Analysis of Human Peripheral Blood Mononuclear Cells Exposed to Lassa Virus and to the Reassortant ML29, a Vaccine Candidate
  • organism-icon Homo sapiens
  • sample-icon 26 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

The virulent Lassa fever virus (LASV) and the non-pathogenic Mopeia virus (MOPV) infect rodents and incidentally people in West Africa. The mechanism of LASV damage in human beings is unclear. A live-attenuated reassortant of MOPV and LASV protects rodents and primates from Lassa fever disease. Peripheral blood mononuclear cells from healthy human subjects were expose to either LASV or ML29 in order to identify early cellular responses that could be attributed to the difference in virulence between both viruses. Differential expression of interferon-related genes as well as coagulation-related genes could lead to an explanation for Lassa fever pathogenesis and lead to protective treatments for Lassa fever disease.

Primate blood signs of arenavirus hemorrhagic fever
  • organism-icon Macaca mulatta
  • sample-icon 21 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Lassa fever virus is a zoonotic pathogen that plagues the endemic areas of West Africa. Rhesus macaques infected with a related arenavirus, LCMV-WE, serve as a model for Lassa-infection of human beings. Using a dose similar to that expected from a needle-stick, monkeys experience an early pre-viremic phase (day 1-3), a viremic phase with febrile onset (day 4-7), and, like human beings who succumb, they die within two weeks. Our goal was to monitor changes in gene expression that parallel disease progression in an effort to 1) identify genes with altered expression after infection, 2) identify genes that could discriminate between a virulent and non-virulent infection, and 3) identify genes encoding products that could serve as treatment targets for FDA-approved pharmaceuticals. Genes related to all three of these categories have been identified and some have been given preliminary validation by quantitative PCR and proteomic studies. These genes will be valuable candidates for future validation as prognostic biomarkers

Early blood profiles of virus infection in a monkey model for Lassa fever.

Usp22 controls multiple signaling pathways that are essential for vasculature formation in the mouse placenta
  • organism-icon Mus musculus
  • sample-icon 5 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

Usp22, a component of the SAGA complex, is over expressed in highly aggressive cancers, but the normal functions of this deubiquitinase are not well defined. We determined that loss of Usp22 in mice results in embryonic lethality due to defects in extra-embryonic placental tissues and failure to establish proper vascular interactions with the maternal circulatory system. These phenotypes arise from abnormal gene expression patterns that reflect defective kinase signaling, including TGFß and several receptor tyrosine kinase (RTK) pathways. Usp22 deletion in endothelial cells and pericytes induced from embryonic stem cells also hinders these signaling cascades with detrimental effects on cell survival and differentiation as well as ability to form vessels. Our findings provide new insights to Usp22 functions during development that may offer clues to its role in disease states. Overall design: To determine changes in gene expression profile upon Usp22 loss in the developing placenta, RNA from day E9.5 placentas from wild-type and Ups22-/- mice s was isolated for deep sequencing, in triplicates and duplicates respectively. Key genes identified from RNAseq were validated by qRT-PCR using RNA from the same samples that were used for sequencing.
