Project description:To determine CREBH-mediated hepatic gene expression changes in hifh-fat high-sucrose (HFHS) dit feeding, we employed the microarray analysis. We collected the livers from male WT and CREBH-Tg mice fed with HFHS diet for 12 weeks from 6 weeks old.
Project description:Genome wide DNA methylation profiling of liver tissues from Pemt-/- and Pemt+/+ under HFHS diets. Pemt-/- and Pemt+/+ mice were fed HFHS from 5 to 25 weeks of age and liver tissues were obtained at 25 weeks. Bisulphite converted DNAs were enriched with EpiXplore Methylation DNA Enrichment Kit (Clontech). Genomic DNA libraries was prepared by TruSeq ChIP Sample Preparation Kit.
Project description:To explore the transcriptional heteroeneity of oxytocin neurons, we fluorescence-assisted nuclei sorting (FANS) conditionally tagged nuclei from Oxt-ires-Cre;CAG-Sun1sfGFP mice. All mice were littermates and fed either SC diet or HFHS diet for 4 months. Individual nuclei were sorted into 384w plates and subjected to SMART-seq2.
Project description:We used microarrays to detail the global programme of gene expression in the liver of Pemt-/- and Pemt+/+ under HFHS diets. Liver sample of Pemt-/- and Pemt+/+ mice under HFHS for 1, 2, 3, 4 weeks were used for RNA extraction and hybridization on Affymetrix microarrays. Genes in liver of Pemt-/- mice, successively suppressed compared with Pemt+/+ mice, were obtained.
Project description:C57Bl6/J male mice were put on different diets at 5 weeks of age, with a standard diet (SD) or a High-Fat High-Sucrose Diet (HFHS) or a Choline-Deficient High-Fat Diet (CDHFD) during 6 months. Primary hepatocytes cultures from 3 different models were synchronized in the cell cycle. Transcriptomic analysis was perfomed at 48hours of culture when HFHS and CDHFD hepatocytes harbor replication stress.
Project description:Hypercaloric diet affects hypothalamic cells at different levels. However, the time-dependent transcriptional changes of hypothalamic cells, and more particularly ARC cells, following the exposure to a HFHS diet are largely unknown. We used single cell RNA sequencing (scRNA-Seq) to analyze the impact of HFHS diet feeding on the transcriptional profile of ARC cells at different timepoints, with a special focus on astrocytes. The timepoints analyzed consist in 5 and 15 days of HFHS diet exposure, at which mice gain a not significant or a significant body weight respectively.
Project description:To gain insight into the role of testosterone in modulating hepatic fat accumulation, we collected liver tissues from high fat diet-fed intact male pigs, castrated male pigs, and castrated male pigs with testosterone replacement. RNA-Seq was employed to profile hepatic gene expression in pigs with different testosterone levels. Liver mRNA profiles of intact male pigs fed a HFC diet, castrated male pigs fed a HFC diet, and castrated male pigs treated with testosterone fed a HFC diet were generated by deep sequencing, using Illumina HiSeq 2000.
Project description:Hepatic transcriptome of junctional adhesion molecule A knockout, F11r–/– mice fed a Western diet (WD) for eight weeks. A cohort of WD-fed mice were treated with IgG or α4β7 mAb for four weeks starting at week four following initiation of the WD.
