View SamplesThe Ptf1a gene has essential functions during several stages of pancreas development. It is expressed in the nave endoderm and required pancreas cell fate specification; it is also required later in the differentiation and maintenance of acinar cells. To identify the regulatory genetic program downstream of Ptf1a required for early pancreatic fate acquisition, we used microarrays to perform a comprehensive gene expression analysis of Ptf1a overexpressing endodermal tissue at NF32 and NF36.

View SamplesNgn3 is a master regulator of pancreatic endocrine development. It is necessary for the creation of all endocrine cells in mice. Little is known about the genes that act downstream of the transcription factor Ngn3 in pancreas endocrine development to specify each of the endocrine lineages. As a consequence, little is known about the genes involved in early development and the specification of the beta cell. We used microarrays to identify Ngn3 downstream genes that are involved in early and ectopic beta cell development in Xenopus laevis. We overexpressed Ngn3 in the Xenopus early endoderm and analyzed the genes that are upregulated four hours after.
Transient expression of Ngn3 in Xenopus endoderm promotes early and ectopic development of pancreatic beta and delta cells.

View SamplesTo investigate effects of intake of mulberry leaves on hyperlipidemia, we performed gene expression profiling on rat liver by microarray analysis.
Ameliorative effects of mulberry (Morus alba L.) leaves on hyperlipidemia in rats fed a high-fat diet: induction of fatty acid oxidation, inhibition of lipogenesis, and suppression of oxidative stress.

View SamplesUrechis unicinctus, a benthic marine worm inhabiting widely in the coast of Russia, Japan, Korean Peninsula and China, present special biological characteristics in morphology, reproductive and developmental biology as well as physiology. It could exist in condition of low oxygen, high sulfide and pollution where most animals could not live. However, the molecular mechanisms of resistance are still unknown and the main obstacle to further study is the limited genomic and genetic information. In order to improve the situation, we performed and acquired its transcriptome database.

View SamplesIn this experiment we catalogue transcriptional changes accompanying COPD in the quadriceps. We measure global gene transcription in the quadriceps using Affymetrix HuGene 1.1 ST arrays in an unselected cohort of 79 stable COPD patients in secondary care and 16 healthy age-and gender-matched controls.
COPD is accompanied by co-ordinated transcriptional perturbation in the quadriceps affecting the mitochondria and extracellular matrix.

View SamplesAsthma is characterized by intermittent inflammation of the airways, airflow limitation and wheeze. The ORMDL3 locus on chromosome 17q21 confers the major genetic susceptibility to childhood asthma. Although sphingolipids are important in immune signalling, the mechanisms of action of ORMDL3 on airway inflammation are incompletely understood.

View SamplesThe progression to AIDS is influenced by changes in the biology of heterogeneous monocyte subsets. Classical (CD14++CD16-), intermediate (CD14++CD16+), and nonclassical (CD14+CD16++) monocytes may represent progressive stages of monocyte maturation or disparate myeloid lineages with different turnover rates and function. To investigate the relationship between monocyte subsets and the response to SIV infection, we performed microarray analysis of monocyte subsets in rhesus macaques at three timepoints: prior to SIV infection, 26 days post-infection, and necropsy with AIDS. Genes with a 2-fold change between monocyte subsets (2023 genes) or infection timepoints (424 genes) were selected. We identify 172 genes differentially expressed among monocyte subsets in both uninfected and SIV-infected animals. Classical monocytes express genes associated with inflammatory responses and cell proliferation. Nonclassical monocytes express genes associated with activation, immune effector functions, and cell cycle inhibition. The classical and intermediate subsets are most similar at all timepoints, and transcriptional similarity between intermediate and nonclassical monocytes increases with AIDS. Cytosolic sensors of nucleic acids, restriction factors, and interferon-stimulated genes are induced in all three subsets with AIDS. We conclude that SIV infection alters the transcriptional relationship between monocyte subsets and that the innate immune response to SIV infection is conserved across monocyte subsets.
