Project description:Effects of extensive fasting on hepatic transcription
| PRJNA114081 | ENA
Project description:Temporally restricted feeding has a profound effect on the circadian clock. Fasting and feeding paradigms are known to influence hepatic transcription. This dataset shows the dynamic effects of refeeding mice after a 24hour fasting period.

Project description:Temporally restricted feeding has a profound effect on the hepatic circadian clock. While the circadian clock is largely unaffected by by extensive fasting, many transcripts are known to be affected by a fasting paradigm. This dataset shows the effect of extensive fasting on dynamic gene expression in the liver

This dataset shows the effect of extensive fasting on dynamic gene expression in the liver C57/B6 mice were entrained to ad libitum feeding schedule for two weeks. They were then released into constant were food was withdrawn at CT16. On the second day in constant darkness tissue was collected at the indicated timepoints. Total RNA was extracted and 5ug of total RNA was used for the standard Affymetrix protocol of amplification, labeling and hybridization

Project description:The effects of temporally restricted feeding on hepatic gene expression
| PRJNA114075 | ENA
Project description:Using an "omics"-based approach, we investigated the interaction between the autonomous liver clock and feeding-fasting rhythm. Transcriptomic analysis and subsequent quantification of exonic and intronic reads revealed that transcriptional mechanisms mediate, at least in part, the integration of feeding signals by the liver clock to drive mRNA oscillations. Therefore, we performed ATAC-seq to probe the state of chromatin accessibility genome-wide. While most open chromatin regions are unchanged across genotype, time and feeding status, transcription factor (TFs) footprints showed altered activity of certain TFs in Liver-RE AL vs NF. For example, CEBPB activity is altered in Liver-RE AL and restored in NF, an observation accompanied by restored CEBPB and BMAL1 common target gene oscillations. Finally, metabolomics analysis illustrated the partial rescue of hepatic metabolism in Liver-RE NF compared to AL (extensive carbohydrate pathway oscillations), and made clear that extra-hepatic clocks contribute significantly to metabolic oscillations in the liver, particularly for pathways involving lipids.

Project description:Temporally restricted feeding has a profound effect on the circadian clock. Fasting and feeding paradigms are known to influence hepatic transcription. This dataset shows the dynamic effects of refeeding mice after a 24hour fasting period. Mice were entrained for two weeks under ad libitum access to food. Mice were then released into constant darkness and food was withdrawn at CT4 on the first day in constant darkness. On the second day in constant darkness mice were either fed (Refed) or continously fasted (Fast) at CT4. Liver tissue was collected at the indicated timepoints. Total RNA was extracted and standard Affymetrix protocol were used for amplification, labeling and hybridization
