Affymetrix Mouse Gene 1.1 ST Array (mogene11st)
Description
Nuclear receptors (NRs) are ligand-activated transcription factors regulating a large variety of processes involved in reproduction, development, and metabolism. NRs are ideal drug targets. Immortalized cell lines recapitulate NR biology very poorly and primary cultures are laborious and require a constant need for donor material. There is a clear need for development of novel preclinical model systems that better resemble human physiology since technical uncertainty early in drug development is the cause of many preclinical drugs not reaching the clinic. Here, we studied whether organoids, mini-organs derived from the respective tissues stem cells, can serve as a novel (preclinical) model system to study NR biology and targeteability. We characterized mRNA expression profiles of the NR superfamily in mouse liver, ileum, and colon organoids. NR mRNA expression patterns were similar to the respective tissues, indicating their suitability for NR research. Metabolic NRs Fxr, Lxr, Lxr, Ppar, and Ppar were responsive to ligands in an NR-dependent fashion, as demonstrated by regulation of expression and binding to endogenous target genes. Transcriptome analyses of wildtype colonic organoids stimulated with Rosiglitazone showed that lipid metabolism was the highest significant changed function, greatly mimicking the known function of PPARs and Rosiglitazone in vivo. In conclusion, our results demonstrate that organoids constitutes a versatile and promising in vitro system to study NR biology and targeteability.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
In mammals, resident dermal macrophages (Ms) are subverted by Leishmania (L.) amazonensis amastigotes as host cells permissive for parasite multiplication. These Leishmania are living within a communal parasitophorous vacuole (PV) and are expected to trigger unique M transcriptional signatures. We performed a transcription profiling of mouse Ms harboring amastigotes to get insights into their reprogramming as host cells for parasite multiplication. BALB/c mouse bone marrow-derived Ms were either loaded or not with four amastigotes on average. Twenty four hours later, when amastigotes multiply, total RNA from M cultures was prepared, amplified and hybridized onto Affymetrix Mouse430_2 GeneChips. The outcome recorded a total of 1,248 probe-sets showing significant differential expression. Comparable fold-change values for a handful of genes were obtained between Affymetrix technology and the more sensitive RTqPCR method. Ingenuity Pathway Analysis software pinpointed the up-regulation of the sterol biosynthesis pathway (P-value = 1.31e-02) involving several genes (1.95 to 4.30 fold-change values), and the modulation of various genes involved in polyamine synthesis and in pro/counter-inflammatory signaling. Our findings suggest that amastigotes exploit the M lipid and polyamine pathways to multiply efficiently, and induce a counter-inflammatory environment to expand their dermis niche.

Illumina HiSeq 2000
Description
The Gfi1-Cre mouse is commonly used for conditional hair cell-specific gene deletion/activation in the inner ear. However, we have shown that these mice produce a pattern of recombination that is not strictly limited to hair cells, and that Gfi1cre/+ mice exhibit an early onset progressive hearing loss as compared with their wildtype littermates. Here we performed a transcriptome analysis of Gfi1cre/+ and Gfi1+/+ cochlea to detect potential changes in gene expression that could contribute to their hearing loss phenotype, or that could potentially confound downstream analysis of conditional gene deletion using these mice. Overall design: Trancriptome profiles of P8 cochlear duct from mice of two genotype - Gfi1cre/+ and Gfi+/+ controls - were measured. Gene expression levels were recorded in independent triplicates using polyA-enriched RNA-seq

Description
Background: The bile acid-activated farnesoid X receptor (FXR) is a nuclear receptor regulating bile acid, glucose and cholesterol homeostasis. Obeticholic acid (OCA; also known as INT-747 or 6-ethyl-chenodeoxycholic acid), a promising drug for the treatment of non-alcoholic steatohepatitis (NASH) and type 2 diabetes, activates FXR. Mouse studies demonstrated that FXR activation by OCA (INT-747) alters hepatic expression of many genes. However, no data are available on the effects of OCA in human liver. Here, we generated gene expression profiles in human precision-cut liver slices (hPCLS) after treatment with OCA.
