Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Here, we investigated the role of EphA4 in the molecular response to sleep deprivation by measuring forebrain gene expression in EphA4 KO mice. More precisely, we measured the effect of the mutation and of a 6-h sleep deprivation on genome-wide forebrain gene expression using microarray.

Description
Prosaposin encodes, in tandem, four small acidic activator proteins (saposins) with specificities for glycosphingolipids hydrolases in lysosomes. To explore the molecular mechanism(s) of disease progression, temporal transcriptome microarray analyses of cerebrum and cerebellum tissues were conducted using mRNA from three prosaposin deficiency mouse models: PS-NA (hypomorphic prosaposin deficiency), PS-/- (prosaposin null) and 4L/PS-NA (a V394L/V394L glucocerebrosidase mutation and PS-NA) mice. Our results indicate that regionally specific gene expression abnormalities preceded the histological and behavioral changes and CEBPD is a candidate regulator of brain disease in prosaposin deficiency. The alterations of gene expression are detected at birth and are more profound in cerebellum than cerebrum.

Description
The comparative whole genome transcriptome effects of two similar pharmaceuticals, imig or vela, on a Gaucher disease mouse model, 9V/null, were evaluated by two commonly used platforms, mRNA-Seq and microarray. Also, statistical methods, DESeq and edgeR for mRNA-Seq and Mixed Model ANOVA for microarray, were compared for differential gene expression detection. The biological pathways were similar between two platforms. Cell growth and proliferation, cell cycle, heme metabolism, and mitochondrial dysfunction were the most altered functions associated with the disease process. Although the two biopharmaceuticals have a very similar structure and function, imig- and vela- treatment in the mice differentially affected disease-specific pathways indicating the action of the two drugs on the disease process in the visceral tissues of Gaucher mouse model differ significantly at the molecular level. This study provides a comprehensive comparison between the two platforms (mRNA-Seq and microarray) for gene expression analysis and addresses the contribution of the different methods involved in the analysis of such data. The results also provide insights into the differential molecular effects of two similar biopharmaceuticals for Gaucher disease treatment.

Description
Gaucher Disease (GD) is caused by defective glucocerebrosidase (GCase) activity and the consequent accumulation of its substrate, glucosylceramide (GC). This excess of accumulation of GC leads to broad functional impairments in multiple organs, but the pathogenic pathways leading to lipid laden macrophages (Gaucher cells) in visceral organs and their abnormal function is obscure. To understand the molecular pathogenesis of GD, developmental global gene expression was conducted by microarray analyses of total mRNAs from lung and liver of two distinct GCase point-mutated mice (V394L/V394L and D409V/null) and genetic background matched wild-type controls. INFg regulated pro-inflammatory and IL-4 regulated anti-inflammatory cytokine/mediator network were constructed in the lung and liver of GCase mutant mice. Progressive alterations of the INFg and IL-4 pathways were similar, but to different degrees, in visceral tissues from the two different GCase mutated mice. These analyses implicate IFNg regulated pro-inflammatory and IL-4 regulated anti-inflammatory networks in the differential pathophysiological progression.

Description
This series represents murine dorsal neural tube bisected along the midline with one half from each embryo used for control and the other half treated with 10-6M RA dissolved in ethanol for 6, 12, 24 or 48 h. For 6 h exposures, the explants were cultured overnight on fibronectin coated 35mm dishes (Biocoat, Becton Dickinson Labware, Bedford, MA) in DMEM with 10% horse serum in order to allow for sufficient outgrowth of neural crest cells. The RA was added the following morning; RMA Express 0.2 used to initially normalize data; GeneSpring (Silicon Genetics, Inc.) used for subsequent analysis

Description
Gaucher disease type 1 is an inborn error of metabolic disease with the defective activity of the lysosomal enzyme acid b-glucosidase (GCase). Enzyme replacement/reconstitution therapy (ERT), infusions with purified recombinant GCases, is efficacious in reversing hematologic, hepatic, splenic, and bony disease manifestations in Gaucher type 1 patients. However, the tissue specific molecular events in Gaucher disease and their response to therapy are not known yet. To explore the molecular events underlying GCase treatment, we evaluated the tissue-specific gene expression profiles and molecular responses in our Gaucher disease mouse model, which were treated with two FDA approved commercially available GCases, imiglucerase (imig) and velaglucerase alfa (vela). Using microarray and mRNA-Seq techniques, differentially expressed genes (DEGs) were identified in the spleen and liver by the direct comparison of imig- vs. vela-treated mice. Among them three gene expression networks were derived from these spleens: 1) cell division/proliferation, 2) hematopoietic system and 3) inflammatory/macrophage response. Our study showed the occurrence of differential molecular pathophysiologic processes in the mice treated with imig compared with vela even though these two biosimilars had the same histological and biochemical efficacy
