Mouse and rat liver and liver cell line LC-MS/MS

ABSTRACT: This study sought to interrogate the effects of lipids and lipid metabolites on the hepatic proteome. Protein expression and tyrosine phosphorylation in high-fat diet (HFD) mouse livers vs. livers of normal chow fed (NC) mice were investigated using multiplexed quantitative LC-MS/MS (TMT labeling). Additionally, the rat hepatoma cell line H4IIE was used to monitor the effects of free fatty acids on tyrosine signaling, gene expression and the levels of reactive oxygen species. These data were used to inform potential points of intervention and chemical perturbations and their effects on phenotypic and signaling output in the cell line, and included small molecule inhibtors of Src-family kinases and antioxidants. Based on the in vitro effects, HFD mice were fed an antioxidant and phenotypic and tyrosine signaling changes were measured.

Mouse liver expression additional replicates

Project description:This study sought to interrogate the effects of lipids and lipid metabolites on the hepatic proteome. Protein expression in high-fat diet (HFD) mouse livers vs. livers of normal chow fed (NC) mice were investigated using multiplexed quantitative LC-MS/MS (TMT labeling). This experiment contains additional replicates for normal chow and mice on high-fat diet for 16 weeks.

Proteomic profiling by array of tyrosine kinase activity in metastatic malignant melanoma from human tissue specimens

Project description:Tyrosine kinase activity profiling of metatstatic malignant melanoma and normal skin tissue samples was performed using peptide kinase arrays. All samples were run in triplicates with and withouth inhbitor PLX4032 and Sutent Malate in order to identify how tyrosine kinases responds to kinase inhibitor treatment, ex vivo.

High fat diet-induced changes of mouse hepatic transcription and enhancer activity can be reversed by subsequent weight loss

Project description:In this setup we have used RNA-seq, DHS-seq, and H3K27ac ChIP-seq to identify changes in transcription, chromatin landscape and enhancer activity in livers of mice fed a high fat diet (HFD) and mice returned from HFD to Chow.

Genome-wide expression profile of livers from mice fed HFD,SO-HFD or Viv chow [RNAseq]

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.

Transcriptome analysis of multiple obese mouse models to identify commonly unregulated genes in liver

Project description:Purpose: RNAseq analyses were conducted to screen for the genes undergoing transcriptional changes either in the liver of high-fat-diet (HFD)-induced obese mice or in the liver of Lepr-deficient db/db mice compared to the livers of the respective control mice Methods: C57BL/6 wild-type male mice were fed on high-fat diet (HFD) or a low-fat diet (NCD) for 18 weeks starting from 6 weeks of age, and the livers were collected at 24 weeks of age at ad libitum-fed condition.Misty/misty or db/db were sacrificed at ad libitum-fed condition at 10weeks and the liver was collected. Results: 2079 genes and 1085 genes were identified in high-fat-diet fed mice and db/db mice, respectively.

Hepatic tissue expression profiles of insulin-sensitive obese mice, insulin-resistant mice and control mice

Project description:Male C57BL/6J mice were fed a high-fat diet (HFD, 60 kcal% fat, D12492, Research Diets, Inc) or normal standard chow diet with 10 kal% fat (ND, D09100304, Research Diets, Inc). Specifically, 6-week-old mice were fed a HFD for 12 weeks to induce insulin resistance (HFD-12w group); 14-week-old mice were fed a HFD for 4 weeks to induce obesity (HFD-4w group). Control mice were fed a ND continuously for 12 weeks starting at 6 weeks of age (ND group). All mice reached the experimental endpoint at 18 weeks of age. Insulin sensitivity was measured by glucose tolerance test and insulin tolerance test. Mice that developed insulin resistance in HFD-12w group and obese mice with normal insulin sensitivity in HFD-4w group were used for further experiments. Mice in ND group were used as controls. Upon reaching the experimental endpoint, livers from three insulin-resistant mice, three insulin-sensitive obese mice, and three control mice were removed for RNA sequencing.
