Project description:Purpose: Aim of the study is to identify changes in hepatic gene expression induced by either a 40kcal% coconut oil rich high fat diet (HFD), a 40kcal% soybean oil plus coconut oil high fat diet (SO-HFD) or a low fat vivarium chow diet (Viv). Methods: Livers from mice that had been fed one of the above mentioned diets for 35 weeks, were used to make cDNA libraries that were then sent for deep sequencing, using the Illumina TruSeq RNA. Result: Many genes involved in metabolism, lipid binding, transport and storage and many Cyp genes are dysregulated in the two high fat diets as compared to Viv HFDs in SO-HFD mice. Comparing the two HFDs shows more metabolism and disease related genes dysregulated in SO-HFD vs HFD. Conclusion: A diet high in soybean oil may be more detrimental to metabolic health than a diet high in saturated fats. cDNA isolated from livers from mice fed HFD, SO-HFD or Viv for 35 weeks, were 50bp pair-ended sequenced in triplicate using Illumina TruSeq RNA Sample Prep v2 Kit.
Project description:To investigate the potential mechanism by which RECS1 regulate metabolic disorder, we treated control mice and RECS1 HKO mice with HFD for 8 weeks, and performed microarray to identify the expression pattern and the potential important molecules regulated by RECS1. We used microarrays to detect the global gene expression in the livers of control mice and RECS1 HKO mice after treatment with HFD for 8 weeks and identified distinct classes of altered genes in the livers of mice upon HFD compared .
Project description:In order to establish an obese mouse model, female mice were continuously fed with a high-fat diet (HFD) or a normal diet (control) for 16 weeks beginning at three weeks of age. In this paper, these mice are termed ‘HFD mice’ and ‘control mice’, respectively. Accordingly, we call their oocytes ‘HFD oocytes’ and ‘control oocytes’. Substantial evidence indicates that the effects of maternal obesity on embryo/offspring development can be attributed to factors within the oocyte (9). To identify such potential effectors, we performed a comparative proteomic analysis of ovulated MII oocytes from control and HFD mice.
Project description:Gene expression in livers of male wild-type (WT) and OGG1-deficient (Ogg1-/-) mice fed either a chow diet or a high-fat diet (HFD) were examined. Mice were fed the diet for 10 weeks prior to tissue collection and were 22 weeks of age at the time of tissue collection. 24 Total samples were analyzed. We generated the following pairwise comparisons using GeneSifter: WT Chow vs Ogg1-/- Chow; WT HFD vs. Ogg1-/- HFD using t-test followed by Benjamini and Hochberg correction. An adjusted p-value less than 0.05 was considered to be statistically significant.
Project description:To understand the fibrotic response in the CDA-HFD induced NASH fibrosis model, we performed RNA-seq on liver samples collected from mice fed with normal chow (week 0) or CDA-HFD chow (weeks 8 and 16).
Project description:Genomic DNA was extracted from tumors that developed in C57BL/6 mice fed with CD-HFD for 12 months alone or fed with CD-HFD for 12 months followed by 8 weeks of treatment with anti-PD-1. DNA extracted from five pooled tail-clips of C57BL/6 mice was used as reference DNA.
