(Submitter supplied) The mechanisms by which cholesterol promotes NAFLD remain far less clear. Animal models are necessary to explore the pathogenesis and therapies of NAFLD. Several previous studies have shown that pig breeds can differ in their metabolic phenotype in response to high-energy diet. To investigate whether genetic background has profound effects on pig NAFLD phenotype and their metabolic response to dietary cholesterol intake, we performed RNA-Seq on liver tissues from two miniature pig breeds fed either standard or a high-fat and high-cholesterol diet for 6 months.

(Submitter supplied) Testosterone deficiency causes fat deposit, particularly in the visceral region, and its replacement might reverse fat accumulation, but the underlying mechanisms of such processes are largely unclear. To gain insights into the genome-wide role of testosterone on visceral adipose tissue (VAT), RNA-Seq was used to investigate testosterone deficiency induced changes of VAT in miniature pigs fed a high-fat and high-cholesterol (HFC) diet among intact male pigs (IM), castrated male pigs (CM), and castrated male pigs with testosterone replacement (CMT) treatments. more...

Purpose: We used RNA-seq to determine the liver transcriptome of male and female F1 of MO and control fed mothers. Methods: Female Wistar rat mothers ate control (C) or obesogenic (MO) diet from the time they were weaned through breeding at postnatal day (PND) 120, delivery and lactation. more...

(Submitter supplied) We used transcriptomics to identify vascular gene expression profiles of high-fat-fed Tibetan minipig induced-hypercholesterolemia and atherosclerotic models, to verify the hypothesis that hypercholesterolemia induces innate and adaptive immune responses to accelerate atherosclerosis. Results showed that hypercholesterolemia and atherosclerosis models occurred in the high-fat fed minipigs at 8 and 24 weeks. more...

(Submitter supplied) Miniature pigs are useful model animal for gene expression studies on dietary-induced hyperlipidemia, because they have similar digestive physiology to human. Two typical dietary components were used for dietary-induced hyperlipidemia miniature pig models. One is a high-fat and high-cholesterol diet (HFCD) containing 15% lard and 2% cholesterol, the other is a high-fat, high-cholesterol and high-sucrose diet (HFCSD) containing 15% lard, 2% cholesterol and 37% sucrose.

(Submitter supplied) In order to study the heart disorder that the long term, high energy diet caused, Bama miniature pigs were fed a high-fat, high-sucrose diet for 23 months. These pigs developed symptoms of metabolic syndrome and showed cardiac steatosis and hypertrophy with a greatly increased heart weight (1.82-fold, P<0.05) and heart volume (1.60-fold, P<0.05) compared with the control pigs. To understand the molecular mechanisms of cardiac steatosis and hypertrophy, nine pig heart cRNA samples were hybridized to porcine GeneChips.

(Submitter supplied) Inflammation, mediated by liver-resident Kupffer cells (KCs) and recruited infiltrating macrophages (IMs), plays a critical role in NAFLD pathogenesis. Cholesterol induces pro-inflammatory cytokine production by macrophages and has been identified as a key factor involved in progression from simple steatosis to NASH. In this study, using the fructose, palmitate, cholesterol & trans-fat (FPC) diet model which recapitulates human NAFLD, we aimed to determine the impact of cholesterol manipulation on NAFLD progression/regression and macrophage phenotype in vivo.The transcriptomic evaluation of hepatic macrophages from mice fed with FPC diet contained the highest concentration of cholesterol (1.25%) suggest these cells might contribute to liver inflammation, steatohepatitis, and hepatocarcinoma pathways during the progression phase.

Nanyang black pig, a China indigenous breed, was famous for its high lipid deposition and high genetic divergence, which made it an ideal model investigating mechanism of lipid position traits in pig. Here, transcriptome and TMT-based proteome analyses were carried out in longissimus dorsi (LD) tissue of high genetic variation individual Nanyang black pigs. more...

(Submitter supplied) An excessive high-fat/energy diet is a major cause of obesity and associated complications, such as non-alcoholic fatty liver disease (NAFLD). Betaine has been shown to effectively improve hepatic lipid metabolism. However, the mechanistic basis for this improvement is largely unknown. Herein, integration of transcriptomics sequencing (RNA-seq) and ribosome footprints profiling (Ribo-seq) was used to investigate the means by which betaine alleviates hepatic lipid metabolic disorders induced by a high-fat diet. more...

(Submitter supplied) The liver immune microenvironment is a key element in the development of hepatic inflammation in NAFLD. However, the precise immune cell subsets that exacerbate fatty liver remain elusive. ApoA4 deficiency increases the hepatic lipid burden, insulin resistance, and metabolic inflammation. The aim of this study was to profile the hepatic immune cells affected by ApoA4 in NAFL. We performed scRNA-seq on liver immune cells from WT and ApoA4-deficient mice administered a high-fat diet.

(Submitter supplied) Dysregulation of lipid metabolism is the pathological basis of the occurrence and development of atherosclerosis.The pig is an ideal animal to study human cardiovascular diseases. However, the specific changes of lipid metabolism in its atherosclerotic plaques, as well as the underlying mechanisms, remain to be elucidated. To investigate the alterations of lipid metabolism related pathways, especially ceramide synthesis related genes, in the abdominal aorta of atherosclerotic pigs induced by high-fat, high-cholesterol, and high-fructose (HFCF) diet, we performed RNA-Seq on abdominal aorta tissue from Wuzhishan pigs fed either normal chow diet or HFCF diet for six months.
