Project description:We aim to establish NAFLD model of Zebrafish. Zebrafish larvae fed with high cholesterol diet，high fructose diet and overfeed diet to induce liver steatosis. RNA-seq was employed to analyze the effects of different diets on NAFLD development.
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: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 investigate the effect of diet and Yap KD on liver matastasis, we injected MC38 cells in LFD-fed or HFD-fed mice, and MC38 with shCon or shRNA for Yap (shYap1) in HFD-fed mice We then performed gene expression profiling analysis using data obtained from RNA-seq of these 4 different conditions
Project description:Transcriptional profiling of 3dpf wild type zebrafish larvae treated with 20mM PTZ for 30 and 90 minutes compared with 3dpf wild type control untreated zebrafish larvae.
Project description:In this work we investigated how the brain proteome of the larval zebrafish is modified by behavioral adaptation to the environmental challenge of a water vortex. We monitored the behavior of larvae and observed that they behaviorally adapted to the presence of a water vortex. We obtained the larval zebrafish brain proteome by extracting brains from zebrafish larvae and analyzing them using and LFQ-based LC-MS/MS-approach. In total we identified 5929 proteins in the larval brain. Within this proteome, we identified 57 proteins that were significantly regulated following experience of the water vortex: 41 proteins were up regulated and 16 were down regulated. Of these, 29 proteins are known to have neuronal functions, 17 proteins are known to have other cellular functions, and 11 proteins are still uncharacterized.
