RNAseq of livers of mice fed high fat high sugar diet and either untreated or treated with curcumin liposomes or calcitriol liposomes

Project description:Non-alcoholic fatty liver disease (NAFLD) is a common complication of obesity, where insulin resistance and hepatocyte fat deposition may progress to steatohepatitis (NASH) and fibrosis/ cirrhosis. NASH has no approved treatment. Consequent upon hepatic fat deposition, NF-κB activation in hepatic myeloid cells mediates inflammation and NASH progression. We delivered micro-doses of liposome-encapsulated lipophilic NF-κB inhibitors, curcumin or 1,25-dihydroxy-vitamin D3 (calcitriol), to the pro-fibrogenic inflammatory liver macrophages and dendritic cells (DCs) in diet-induced NASH. After i.v. administration, liver was the primary organ targeted. MHC class-II+ hepatic DCs taking up liposomes in mice and human were F4/80+ and CD14+ respectively, were lipid-laden and expressed pro-inflammatory genes. Curcumin or calcitriol liposomes suppressed hepatic inflammation, fibrosis and fat accumulation, and reduced insulin resistance associated with suppression of immune activation, cell cycle and collagen deposition pathways in vivo. Thus, hepatic inflammatory DCs passively targeted with liposomes encapsulating lipophilic NF-κB inhibitors are beneficial in NASH.

RNA-next generation sequencing of intestine tissue from mice fed high fat diet or/and sugar drink

Project description:Purpose: NGS was used to determine if a distinct transcriptomic profile is observed among the experimental mice fed four different dietary components. Methods: We carried out RNA-Seq analysis of ileum tissue from 6 weeks male mice ad libitum fed for 10 weeks a high liquid sugar (23% (w/v)) or/and high fat (60% Kcal from fat) diet. The combined effect of sugar drink and high fat diet (HF-Sugar) was compared with sugar drink only (NF-Sugar), or high fat diet only (HF), or control diet that was plain water and normal fat diet (NF). Results: RNA-Seq revealed sample-specific clusters that included genes responding to each experimental diet. We found only addition of sugar drink to high fat group (HF-Sugar) not NF-Sugar and HF, there was a significant enrichment in biological functions relating to Inflammatory/Immune Responses, especially including dendritic cell (DC) and T cell related signaling pathway. Conclusions: Taken together, our data demonstrate that sugar drink synergistically promotes and exacerbates inflammatory responses driven by the high fat diet.

Differential transcriptional networks regulated by high sugar consumption in normal and high-fat-fed mice

Project description:High sugar consumption, as well as high-fat diet, is a known cause of obesity and metabolic syndrome. However, the synergistic effect of high-sugar and high-fat consumption rarely has been evaluated, especially in terms of transcriptional regulation. Therefore, we focused on the effect of high sugar consumption on hepatic transcriptional networks in normal and high fat-fed mice. C57BL/6J mice were divided into four groups and were provided either 23%(w/v) sugar solution or plain water with either high-fat or normal-fat diet for 10 weeks. As a result, high sugar consumption significantly altered lipid metabolism-related genes in normal fat-fed mice; however, in high fat-fed mice, high sugar consumption altered inflammation-responsive genes rather than lipid metabolism. After all, these modulations eventually increased lipid accumulation in the liver and caused systemic metabolic disturbances. These observations for the first time suggested that high sugar consumption along with high-fat diet could lead to the development of severe metabolic syndrome via altering hepatic transcriptional networks.

Osteopontin expression identifies a subset of recruited macrophages distinct from Kupffer cells in the fatty liver. [Single cell RNA Seq]

Project description:CITE-seq analysis on total CD45+ cells isolated from the livers of mice fed a standard diet (SD) or western diet (WD; fat, cholesterol and sugar) for 12, 24 and 36 weeks. We also performed single cell RNA sequencing analysis of the CD45- cells isolated from the livers of the mice fed the SD or WD for 24 and 36 weeks.

Dietary curcumin ameliorates perturbed insulin homeostasis in the diet-induced obese aged mice

Project description:Although aging is a physiological process to which all organisms are subject, the presence of obesity and type 2 diabetes accelerates biological aging. Recent studies have demonstrated the causal relationships between dietary interventions suppressing obesity and type 2 diabetes and delaying the onset of age-related endocrine changes. Curcumin, a natural antioxidant, has putative therapeutic properties such as reinstating insulin sensitivity in obese mice. However, how curcumin contributes to maintaining insulin homeostasis in aged organisms largely remains unclear. Thus, the objective of this study is to examine the pleiotropic effect of dietary curcumin on insulin homeostasis in a diet-induced obese (DIO) aged mouse model. Aged (18-20 months old) male mice given a high-fat high-sugar diet supplemented with curcumin displayed a different metabolic phenotype compared to mice given a high-fat high-sugar diet alone. Furthermore, curcumin supplementation altered hepatic gene expression profiling, especially insulin signaling and senescence pathways. We then mechanistically investigated how curcumin functions to fine-tune insulin sensitivity. We found that curcumin supplementation increased hepatic insulin degrading enzyme (IDE) expression levels and preserved islet integrity, both of which are beneficial during aging. Our findings suggest that the multifaceted therapeutic potential of curcumin can be used as a protective agent for age-induced metabolic diseases.

Spatial proteogenomics reveals distinct and evolutionarily-conserved hepatic macrophage niches (spatial)

Project description:Analysis of CITE-seq data , Nuclei RNA-seq data and single cell RNA-seq data on CD45+ and CD45- cells isolated from the livers of mice fed a standard diet (SD) or western diet (WD; fat, cholesterol and sugar), from healthy and steatotic human livers, from hamster liver, pig liver, chicken liver, monkey liver and zebrafish liver. We also performed Spatial Transcriptomics analysis on heatlhy mouse livers, NAFLD mouse livers, healthy human livers and steatotic human livers.

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.
