Affymetrix Bovine Genome Array (bovine)
Description
Growth plate chondrocytes were isolated from the distal metacarpus of young dairy cattle (all under 10 mo of age), the chondrocytes were released from the extracellular matrix by digestion with Collagenase P for 4 hours, and the various zones of the growth plate were separated by density centrifugation. The least-dense Hypertrophic Zone (HZ) cells were compared to the most-dense Reserve Zone (RZ) cells. 6 pairs of HZ vs RZ were compared by microarray.

Description
Inactivating EZH2 mutations have been associated with myelofibrosis (MF). Moreover, EZH2 mutations co-exist with the JAK2V617F mutation in a significant cases of MF. To determine the effects of concomitant loss of EZH2 and JAK2V617F mutation in hematopoiesis, we generated Ezh2-deficient Jak2V617F-expressing mice. To gain insights into the mechanisms by which Ezh2 deficiency promotes the development of MF in Jak2V617F knock-in mice, we performed microarray gene expression analysis on sorted LT-HSC from control, MxCre;Jak2VF/+ and MxCre;Jak2VF/+ EZH2-/- mice.

Description
Novel strategies are needed to modulate -cell differentiation and function as potential -cell replacement or restorative therapies for diabetes. We previously demonstrated that small molecules based on the isoxazole scaffold drive neuroendocrine phenotypes. The nature of the effects of isoxazole compounds on cells was incompletely defined. We find that isoxazole largely induced genes that support neuroendocrine and -cell phenotypes, and suppressed a set of genes important for proliferation. Isoxazole alters -cell metabolites and protects glucose-responsive signaling pathways under lipotoxic conditions. Finally, we show that isoxazole improves glycemia in a mouse model of -cell regeneration. Isoxazole is a prime candidate for altering cell fate in different contexts.

Illumina HiSeq 2500
Description
Purpose: To identify the impact of thermoneutral housing as opposed to standard housing on gene expression profiles in the mouse peripheral blood mononuclear cells (PBMCs), focusing on proinflammatory immune responses and high-fat diet induced non-alcoholic fatty liver disease pathogenesis. Methods: Expression profiles from PBMCs collected from C57Bl6 mice fed chow or high-fat diet for 8 weeks, following 2 weeks at either standard or thermoneutral housing conditions. Sequencing was performed in duplicate, the Illumina HiSeq 2500. Transcripts that passed quality filters were analyzed at the gene level, using Strand NGS for accurate alignment and quantification. Results: We mapped approximately 20million reads per sample to the mm10 genome using annotations produced by Ensembl, which represented 36186 transcripts. Approximately 14000 genes exhibited reasonable expression in at least one experimental condition. The primary focus was the effect of housing temperature while holding diet consistent (i.e. thermoneutral vs standard, both on high-rat diet), where ~2700 genes exhibited differential regulation. Conclusions: We present the transcriptomic profile of PBMCs from mice fed chow of high-fat diets, following either standard or thermoneutral housing. We obseve an augmented proinflammatory immune response. Overall design: PBMC expression profiles were characterized following eight weeks of chow or high-fat diet, following two weeks of standard or thermoneutral housing.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
The endoplasmic reticulum (ER) is the site of secretory lipoprotein production and de novo cholesterol synthesis, yet little is known about how these activities are coordinated with each other, or with the activity of the COPII machinery, which transports ER cargo to the Golgi. The Sar1B component of this machinery is mutated in Chylomicron Retention Disorder, establishing that this Sar1 isoform secures delivery of dietary lipids into the circulation.
Publication Title
The endoplasmic reticulum coat protein II transport machinery coordinates cellular lipid secretion and cholesterol biosynthesis.

Description
The respiratory system is a complex network of many cell types, including subsets of macrophages and dendritic cels, that work together to maintain steady-state respiration. Due to limitations in acquiring cells from healthy human lung, these subsets remain poorly characterized transcriptionally and phenotypically. We set out to systemically identify these subsets in human airways, by developing a schema of isolating large numbers of cells by whole lung bronchoalveolar lavage. Six subsets of phagocytic antigen presenting cells were consistently observed, which varied in their ability to internalize bacterial particles. Subsets could be further separated by their inherent capacities to upregulate CD83, CD86, and CCR7. Whole genome transcriptional profiling revealed a clade of true dendritic cells distinct from a macrophage/monocyte clade. Each clade, and each member of both clades, could be discerned by specific genes of increased expression, which would serve as markers for future studies in healthy and diseased states.

Description
To try to identify the mechanism of STAT3s indirect action we have used a genomic approach to map the binding sites of STAT3 within the genome and also used RNA-seq technology to map the changes in RNA expression and transcript isoform abundance in response to IL-10. Overall design: Examination of transcriptome changes in peritoneal macrophages when treated with IL-10 for 4 hours. RNA was extracted and sequenced.
