Genome-wide analysis of gene transcription in myocardium of the doxycycline inducible Tafazzin shRNA knockdown mouse model of Barth syndrome

ABSTRACT: Analysis of the transcriptome of cardiac tissue from mice trangenically engineered with a doxycycline inducible Tafazzin shRNA knockdown to mimic the loss of function of Tafazzin in Barth syndrome. ShRNA induced knockdown mice were compared to wildtype littermates also fed the doxycyline diet. The hypothesis was to investigate adaptive metabolic and compensatory gene transcriptional changes in myocardium of the mouse model of Barth syndrome Total RNA obtained from 2 month old cardiac tissue from the doxycycline inducible shRNA Tafazzin knockdown mouse model of Barth syndrome compared to wildtype littermates also fed 625 mg/Kg doxycycline diet

Genome-wide analysis of gene transcription in myocardium of mice transgenically expressing human cardiolipin synthase 1 (hCLS1) in cardiac tissue

Project description:Analysis of the transcriptome of cardiac tissue from mice transgenically expressing human cardiolipin synthesis. The hypothesis tested was that cardiac specific transgenic expression of cardiolipin synthase alters myocardial lipidomic flux resulting in compensatory metabolic gene transcriptional changes that will attenuate pathological environmental and dietary insults on bioenergetics. Total RNA obtained from cardiac tissue from transgenic cardiac specific expressing human cardiolipin synthase 1 (hCLS1) mouse model at 4 months of age compared to wildtype littermates

Gene expression altered by high-fructose diet feeding and Chrebp deficiency

Project description:Epidemiologic and animal studies implicate overconsumption of fructose in the development of non-alcoholic fatty liver disease, but the molecular mechanisms underlying fructose-induced chronic liver diseases remains largely unknown. We present evidence supporting the essential function of the lipogenic transcription factor ChREBP in mediating adaptation response to fructose and protecting against fructose-induced hepatotoxicity. High-fructose diet (HFrD) activates hepatic lipogenesis via a ChREBP-dependent manner in wildtype mice, while inducing steatohepatitis in Chrebp-KO mice. In Chrebp-KO mouse livers, HFrD reduces levels of molecular chaperones and activates the CHOP-dependent unfolded protein response, whereas administration of chemical chaperone or Chop shRNA rescues liver injury. Gene expression profiling revealed elevated expression of cholesterol biosynthesis genes in Chrebp-KO livers after HFrD, in parallel with increased abundance of nuclear SREBP2. genes expression were compared between livers of wildtype mice fed 70%-fructose-diet v.s. regular chow, and between livers of Chrebp-/- mice v.s. wildtype mice fed 70%-fructose-diet.

Expression data from Bama minipig hearts - high-fat, high-sucrose diet

Project description: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. The control group consisted of 6 Bama pigs fed a control diet, and the HFHSD group comprised 6 pigs that were induced with a HFHS diet, which included 37% sucrose, 53% control diet and 10% pork lard. The pigs were fed twice every day and provided water ad libitum for 23 months. The pigs were fasted for 12 hours and euthanized with ketamine and xylazine. Pig hearts from the HFHSD group pigs (120, 126, 138, 140, 144, and 146) and three control group pigs (157, 159, and 161) were sampled and preserved in liquid nitrogen and then for RNA extraction and hybridization on Affymetrix microarrays.

Exosome-Based Interorgan Transport of Mitochondria from Energetically Stressed Adipocytes

Project description:Samples are small extracellular vesicles isolated from the serum of control mice (WTexo) and adipo-FtMT mice (TGexo) fed a high fat diet with doxycycline for 3 weeks. The adipo-FtMT mouse is a model of doxycycline-inducible, adipocyte-specific overexpression of mitochondrial ferritin (FtMT) to induce mitochondrial dysfunction and oxidative stress

Serotonin signals through a gut-liver axis to regulate hepatic steatosis

Project description:Purpose: While various functions of peripheral serotonin are known, the direct role of serotonin in regulating hepatic lipid metabolism in vivo is not well understood. We studied whether serotonin directly acts on liver to regulate lipid metabolism. Methods: Methods: 12 weeks aged liver-specific Htr2a KO (Albumin-Cre+/-; Htr2aflox/flox, herein named Htr2a LKO) mice and wildtype (WT) littermates were fed a high-fat diet (HFD, 60% fat calories) for 8 weeks. Results: Hepatic lipid droplet accumulation, NAFLD activity score, and hepatic triglyceride levels were dramatically reduced in HFD-fed Htr2a LKO mice compared to WT littermates. Conclusions: Gut-derived serotonin is a direct regulator of hepatic lipid metabolism via a gut TPH1-liver HTR2A endocrine axis. And shows promise as a novel drug target to ameliorate NAFLD with minimal systemic metabolic effects.

Expression data from short hairpin RNA mediated CTCF knockdown in human prostate epithelial cells

Project description:Transcriptional profiling of immortalized human prostate epithelial cells after CTCF knockdown by short hairpin RNA. Knockdown by shRNA targeting CTCF was conducted for 5 days by addition of doxycycline to induce shRNA expression. RNA was purified from triplicate biological replicates of induced and uninduced shRNA samples. Gene expression was quantified by hybridization to Affymetrix Human Transciptome 2.0 arrays.
