DCA-TGR5 signaling activation alleviates inflammatory response and improves cardiac function in myocardial infarction

ABSTRACT: The progression of myocardial infarction (MI) involves multiple metabolic disorders. Bile acid metabolites have been increasingly recognized as pleiotropic signalling molecules that regulate multiple cardiovascular functions. G protein-coupled bile acid receptor (TGR5) is one of the receptors sensing bile acids to mediate their biological functions. In this study, we aimed to elucidate the effects of bile acids-TGR5 signaling pathways in myocardial infarction (MI).Mice underwent either the LAD ligation model of MI or sham operation. Both MI and sham mice were gavaged with 10 mg/kg/d DCA or vehicle control since 3-day before the operation. Administration of DCA improved cardiac function at the 3th-day post-MI. The effects of DCA in the heart were determined by RNA-sequencing experiments.

Exposure of squamous esophageal cell line HET-1A to deoxycholic acid (DCA)

Project description:The involvment of bile acids such as deoxycholic acid (DCA) in gastro-esophageal reflux disease and subsequent Barrettâ??s metaplsia has been postulated. This study examines gene expression induced by exposure to DCA in esophageal cells and may be utilised in cross-comparisions with data derived from gene expression studies of Barrettâ??s esophagus and associated adenocarcinoma. Additionally this study may be used to assess divergence in response to bile acids by comparisons with similar study performed in SKGT4 barrett''s assocaited adenocarcinoma cell line. HET-1A cells were exposed to 300um DCA over 24 hours in duplicate experiments including matched timepoint controls

Transcription profiling of models of cardiac remodelling: myocardial infarction or transverse aortic constriction in left ventricle free wall and septum

Project description:We employed the Affymetrix GeneChip technology to evaluate the patterns of expression in two different in vivo models of cardiac remodeling and in two different regions (left ventricle free wall and septum) of the heart. Mice underwent transverse aortic constriction (TAC); myocardial infarction (MI) or Sham operation and RNA from the left ventricle free wall and the septum was isolated 1 week later.

This study examines gene expression induced by exposure to DCA in esophageal cells and may be utilised in cross-comparisons with data derived from gene expression studies of Barrettâs esophagus and associated adenocarcinoma. SKGT4 cells were exposed to 300um DCA over 24 hours in duplicate experiments including matched timepoint controls. RNA samples were taken at 4, 8, 12 and 24 hours from DCA (DCA) exposed and resting (REST) timepoint controls.

Transcriptional profiling of left ventricle and peripheral blood cells in rats with post-myocardial infarction

Project description:Myocardial infarction (MI) often results in left ventricular (LV) remodeling followed by heart failure (HF). It is of great clinical importance to understand the molecular mechanisms that trigger transition from compensated LV injury to HF and to identify relevant diagnostic biomarkers. In this study, we performed transcriptional profiling of LVs in rats with a wide range of experimentally induced infarct sizes and of peripheral blood mononuclear cells (PBMCs) in animals that developed HF. We used microarrays to investigate gene expression in the left ventricle (LV) accompanying myocardial infarction and concomitant heart failure (HF) in a well validated model of post-infarcted heart failure and to evaluate their reflection in peripheral blood mononuclear cells (PBMCs) Myocardial infarction (MI) was induced in male Wistar rats by ligation of the proximal left coronary artery. The sham-operated group (control group) was subjected to the same protocol, except that the suture was not tied around the proximal left coronary artery. Sham-operated rats (n=6) and rats with small (n=6), moderate (n=6), and large (n=5) MI size were included into the experiment two months after the operation. Then, left ventricules and blood samples were obtained for RNA extraction and hybridization on Affymetrix microarrays. Microarrays were used to compare the LV and PBMCs transcriptomes of control and experimental animals. The development of heart failure was estimated by echocardiography and catheterization.

Transcription profiling of rat heart at several time points after either a myocardial infraction or sham operation

Project description:Myocardial Infarction Model: Sixty nine animals (252 ± 2 g) were randomized to either myocardial infraction (MI) or sham operation. MI were produced by partial ligation of the left coronary artery as described in detail by Loennechen et al. (Loennechen JP, Stoylen A, Beisvag V, Wisloff U, Ellingsen O: Regional expression of endothelin-1, ANP, IGF-1, and LV wall stress in the infarcted rat heart. Am J Physiol Heart Circ Physiol 2001, 280: H2902-H2910.). Animals with large infarctions (45 ± 2% of LV) were euthanized on one of the following days: day 1 (n = 6), 3(n = 5), 7 (n = 6), 14 (n = 6), 42 (n =6) and 91 (n = 4); and sham-operated animals were euthanized on one of the following days: 1 (n = 6), 3(n = 6), 7 (n = 6), 14 (n = 6), 42 (n =6) and 91 (n = 6). After sacrifice, heart tissue was removed, weighted and scored for size of the healed infarction. Infarct size was measured and the left ventricular myocardium stored on -80°C for preparation of RNA.
