Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
The metabolic syndrome (MetS) is characterized by the presence of metabolic abnormalities that include abdominal obesity, dyslipidemia, hypertension, increased blood glucose/insulin resistance, hypertriglyceridemia and increased risk for cardiovascular disease (CVD). The ApoE*3Leiden.human Cholesteryl Ester Transfer Protein (ApoE3L.CETP) mouse model manifests several features of the MetS upon high fat diet (HFD) feeding. Moreover, the physiological changes in the white adipose tissue (WAT) contribute to MetS comorbidities. The aim of this study was to identify transcriptomic signatures in the gonadal WAT of ApoE3L.CETP mice in discrete stages of diet-induced MetS.

Description
We performed RNAseq with Saccharomyces cerevisiae cells under both transient and steady-state conditions to study the regulation of genes by two pulsatile transcription factors, Msn2 and Mig1. The transient data allowed us to identify combinatorial targets while the steady-state data was used to study target expression dependence on the relative pulse timing between the two TFs. Overall design: For transition experiments, 18 samples (3 different strains x 3 dfferent conditions x 2 biological replicates) were analyzed. For steady-state experiments, one strain was analyzed at 9 different glucose concentrations and the other strain was analyzed at one glucose condition.

Description
Background: Recent characterization of the transcriptional landscape of cell lines and whole tissues has suggested widespread transcription of the genome, including loci that produce regulatory non-coding RNAs that function within the nucleus. Methods: Here, we have defined the nuclear transcriptional landscape of the three major cellular divisions of the nervous system using flow sorting of genetically labeled nuclei from bacTRAP mouse lines followed by characterization the unique expression of coding, non-coding and intergenic RNAs in the mature mouse brain with RNAseq, and validation with independent methods. Results: Our findings reveal diverse expression across the cell-types of all classes of RNAs, including long non-coding RNAs - several of which were confirmed as highly enriched in the nuclei of specific cell-types using anatomical methods. Finally, we also discovered several examples of cell-type specific expression of tandem gene fusions, and report the first cell-type specific expression of circular RNAs, notably a neuron specific and nuclear enriched RNA arising from the gene Hnrnpu. Conclusion: These non-coding RNA expression data should provide an important context for studies evaluating the function of a variety of ncRNA in the nervous system. Overall design: Three to four independent replicate samples (each from one mouse) were collected for each of three sample types: Neuronal nuclear RNA, Astrocyte nuclear RNA, Oligodendrocyte nuclear RNA. Controls include low-coverage presorted nuclear RNA from each mouse.

Although meningioma is a common disease, there is a lack of understanding of the underlying molecular mechanisms behind its initiation and progression. We used combined miRNA-mRNA transcriptome analysis to discover novel genes and networks in meningiomas.

Description
UC pouchitis is a potential model of UC. We prospectively examined the pouch transcriptomes of UC and familial adenomatous polyposis (FAP) IPAA patients to unveil molecular mechanisms of UC pouchitis susceptibility. Methods: Total RNA was isolated using the AllPrep DNA/RNA Mini Kit (QIAGEN, Cat No. 8020). RNA quality was evaluated using Bioanalyzer (Agilent, Santa Clara, CA). All RNA samples displayed RNA Integrity Number (RIN) >7. RNAseq including cDNA library preparation was processed at the Genomics Core Facility of University of Chicago (https://fgf.uchicago.edu/). Total RNA in the amount of 100-500µg per sample was depleted of ribosomal RNA using the Ribo-Zero kit (Epicentre, Madison, WI). The directional (first strand) cDNA libraries were prepared following the guide of TruSeq Stranded Total RNA Sample Preparation kit. Results: Unlike FAP patients, UC subjects exhibited a large set of differentially expressed genes (DEGs) between pouch and pre-pouch mucosa as early as 4 months after pouch functionalization. Functional pathway analysis of DEGs in UC pouch revealed: (1) Gain of colon-associated gene expressions and loss of ileum associated gene expressions, (2) enhanced state of immune/inflammatory response, and (3) suppressed xenobiotic, lipid, and bile acid metabolic pathways. These changes were corroborated upon reanalysis of a published larger cross-sectional study of UC and FAP patients. Moreover, >70% of DEGs mapped to published IBD and normal colonic microarray datasets displayed directional changes consistent with active UC, but not Crohn''s disease. Conclusions: UC patients exhibit a unique transcriptomic response to ileal pouch creation that can be observed well before disease. The transcriptome alterations provide insights into pouchitis Overall design: Seventeen patients with UC and four patients with FAP were recruited at the University of Chicago and the Mayo Clinic Rochester. All patients underwent a total proctocolectomy with ileal pouch anal anastomosis (IPAA) as a standard of care. UC patients underwent a pouchoscopy for biopsy of the pre-pouch ileum and pouch at 4 months, 8 months, and 12 months after ileostomy closure. None of these patients had pouchitis.

Description
The immense molecular diversity of neurons challenges our ability to deconvolve the relationship between the genetic and the cellular underpinnings of neuropsychiatric disorders. Hypocretin (orexin) containing neurons of the lateral hypothalamus are clearly essential for the normal regulation of sleep and wake behaviors, and have been implicated in feeding, anxiety, depression and reward. However, little is known about the molecular phenotypes of these cells, or the mechanism of their specification. We have generated a Hcrt bacTRAP line for comprehensive translational profiling of these neuronsin vivo. From this profile, we have identified 188 transcripts, as enriched in these neurons, in additions to thousands more moderately enriched or nominally expressed. We validated many of these at the RNA and protein level, including the transcription factor Lhx9. Lhx9 protein is found in a subset of these neurons, and ablation of these gene results in a 30% loss of Hcrt neuron number, and a profound hypersomnolence in mice.This data suggests that Lhx9 may be important for specification of some Hcrt neurons, and the subsets of these neurons may contribute to discrete sleep phenotypes.

Description
Gut dysbiosis and host genetics are implicated as causative factors in inflammatory bowel disease, yet mechanistic insights are lacking. Longitudinal analysis of ulcerative colitis patients following total colectomy with ileal anal anastomosis (IPAA) where >50% develop pouchitis, offers a unique setting to examine cause vs. effect. To recapitulate human IPAA, we employed a mouse model of surgically-created blind self-filling (SFL) and self-emptying (SEL) ileal loops. SFL exhibit fecal stasis due to directional peristalsis motility oriented towards away from the loop end, whereas SEL remain empty. In wild type mice, SFL, but not SEL, develop pouch-like microbial communities without accompanying active inflammation. However, in genetically susceptible IL-10-/- deficient mice, SFL, but not SEL, exhibit severe inflammation and mucosal transcriptomes resembling human pouchitis. Germ-free IL10-/- mice conventionalized with wild type SFL, but not SEL, microbiota, develop severe colitis. These data demonstrate an essential role for fecal stasis, gut dysbiosis, and genetic susceptibility and offer insights into human pouchitis and ulcerative colitis.

Description
Dengue viruses cause two severe diseases that alter vascular fluid barrier functions, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). While the mechanisms that lead to vascular permeability are unknown, the endothelium plays a central role in regulating fluid and cellular efflux from capillaries. Thus, dysregulation of endothelial cells functions by dengue virus infection may contribute to pathogenesis and severe disease.

Endothelial cells elicit immune-enhancing responses to dengue virus infection.
