Project description:We hybridzed cRNA from epididymal white adipose tissue collected at ZT18 of control animals and TSR animals (TSR: these mice were sleep restricted for 6 hours every day by gentle handling for 5 consecutive days and killed on the last day at ZT18) mice used in this study were C57BL/6 control mice were compared to timed sleep restriction mice (TSR: these mice were sleep restricted for 6 hours every day by gentle handling for 5 consecutive days and killed on the last day at ZT18)
Project description:Circadian rhythmicity in renal function suggests a requirement for circadian adaptations in renal metabolism. We studied circadian changes in renal metabolic pathways using integrated transcriptomic, proteomic and metabolomic analysis performed on control mice and mice deficient in the circadian clock gene Bmal1 in the renal tubule (cKOt mice). Proteins were extracted from whole kidneys of 60 mice. Of these, 30 were conditional knockouts of Arntl (Bmal1) and 30 were of control genotype. They were housed under 12-hours light/12-hours dark cycles and were sacrificed at six different time points: zeitgeber time ZT 0, ZT 4, ZT 8, ZT 12, ZT 16, ZT 20 ( ZT 0 being the time of light on and ZT 12 the time of light off). Five replicates per genotype and time point were analysed.

Project description:We assayed the TOM2 microarray with target RNAs extracted from ZT0 (presumptive dawn), ZT8 (eight hours after dawn), ZT16 (presumptive dusk) and ZT20 (four hours after dusk), in Light/Dark (LD) conditions . The experimental design compared three time points to ZT0 used as a common reference: ZT8 vs. ZT0, ZT16 vs. ZT0 and ZT20 vs. ZT0. Sampling time is expressed as hours after dawn (Zeitgeber Time - ZT)
Project description:To investigate the role of the transcriptional repressor Rev-erb alpha in epididymal white adipose tissue, we performed a microarray analysis of gene expression in the epididymal white adipose tissue of wildtype and Rev-erb alpha knock-out mice. Examination of the transcriptome in epididymal white adipose tissue of Rev-erb alpha kockout mice compared to wildtype mice.

Project description:We applied a deep-sequencing based method – digital gene expression profiling (DGEP), to investigate gene expression in interscapular brown adipose tissue (iBAT), inguinal white adipose tissue (iWAT) and epididymal white adipose tissue (eWAT) in acute cold exposure Examination of gene expression level in 3 different adipose tissues in 3 time points, day0, day2 and day4 in cold exposure.

Project description:Background: The prefrontal cortex is important in regulating sleep and mood. Diurnally regulated genes in the prefrontal cortex may be controlled by the circadian system, by the sleep-wake states, or by cellular metabolism or environmental responses. Bioinformatics analysis of these genes will provide insights into a wide-range of pathways that are involved in the pathophysiology of sleep disorders and psychiatric disorders with sleep disturbances. Results: We examined gene expression in the mouse prefrontal cortex at four time points during the 24-hour (12-hour light:12-hour dark) cycle by microarrays, and identified 3,890 transcripts corresponding to 2,927 genes with diurnally regulated expression patterns. We show that 16% of the genes identified in our study are orthologs of identified clock, clock controlled or sleep/wakefulness induced genes in the mouse liver and SCN, rat cortex and cerebellum, or Drosophila head. The diurnal expression patterns were confirmed in 16 out of 18 genes in an independent set of RNA samples. The diurnal genes fall into eight temporal categories with distinct functional attributes, as assessed by the Gene Ontology classification and by the analysis of enriched transcription factor binding sites. Conclusions: Our analysis demonstrates that ~10% of transcripts have diurnally regulated expression patterns in the mouse prefrontal cortex. Functional annotation of these genes will be important for the selection of candidate genes for behavioural mutants in the mouse and for genetic studies of disorders associated with anomalies in the sleep:wake cycle and circadian rhythms. Experiment Overall Design: Prefrontal cortex from 3 biological replicates of C57BL/6J mice at four Zeitgeber Times (ZT 3, 9, 15, and 21) were analyzed
Project description:The goal of this study is to identify the cistrome of the transcriptional repressor Rev-erb alpha in epididymal white adipose tissue. Performing Rev-erb alpha ChIP-seq on epididymal white adipose tissue from wildtype mice at 5PM when Rev-erb alpha protein level peaks in wild type (WT) mice, we were able to globally determine the genomic regions undergoing Rev-erb alpha-dependent de-repression. Examination of Rev-erb alpha binding in epididymal white adipose tissue.
