2Modulating effects of acyl-CoA synthetase 5-derived mitochondrial Wnt2B palmitoylation on intestinal Wnt activity显示文摘AIM:To investigate the role of acyl-CoA synthetase 5(ACSL5)activity in Wnt signaling in intestinal surface epithelia.METHODS:Several cell lines were used to investigate the ACSL5-dependent expression and synthesis of Wnt2B,a mitochondrially expressed protein of the Wnt signaling family.Wnt activity was functionally assessed with a luciferase reporter assay.ACSL5-related biochemical Wnt2B modifications were investigatedwith a modified acyl-exchange assay.The findings from the cell culture models were verified using an Apcmin/+mouse model as well as normal and neoplastic diseased human intestinal tissues.RESULTS:In the presence of ACSL5,Wnt2B was unable to translocate into the nucleus and was enriched in mitochondria,which was paralleled by a significant decrease in Wnt activity.ACSL5-dependent S-palmitoylation of Wnt2B was identified as a molecular reason for mitochondrial Wnt2B accumulation.In cell culture systems,a strong relation of ACSL5 expression,Wnt2B palmitoylation,and degree of malignancy were found.Using normal mucosa,the association of ACSL5 and Wnt2B was seen,but in intestinal neoplasias the mechanism was only rudimentarily observed.CONCLUSION:ACSL5 mediates antiproliferative activities via Wnt2B palmitoylation with diminished Wnt activity.The molecular pathway is probably relevant for intestinal homeostasis,overwhelmed by other pathways in carcinogenesis.Christina Klaus Ursula Schneider Christian Hedberg Anke K Schütz Jürgen Bernhagen Herbert Waldmann Nikolaus Gassler Elke Kaemmerer 2014World Journal of Gastroenterology2014,20,40:4
3Feasibility and safety of cryoballoon ablation for atrial fibrillation inpatients with congenital heart disease显示文摘BACKGROUND The prevalence of atrial fibrillation (AF) is on the rise in the aging population with congenital heart disease (CHD). A few case series have described the feasibility and early outcomes associated with radiofrequency catheter ablation of AF centered on electrically isolating pulmonary veins (PV) in patients with CHD. In contrast, cryoballoon ablation has not previously been studied in this patient population despite its theoretical advantages, which include a favorable safety profile and shorter procedural time. AIM To assess the safety and feasibility of cryoballoon ablation for AF in an initial cohort of patients with CHD. METHODS The study population consisted of consecutive patients with CHD and cryoballoon ablation for AF at the Montreal Heart Institute between December 2012 and June 2017. Procedural complications, acute success, and 1-year freedom from recurrent AF after a single procedure with or without antiarrhythmic drugs were assessed. Procedures were performed under conscious sedation. Left atrial access was obtained via a single transseptal puncture or through an existing atrial septal defect (ASD). Cryoballoon occlusion was assessed by distal injection of 50% diluted contrast into the pulmonary vein. At least one 240-second cryothermal application was performed upon obtaining complete pulmonary vein occlusion. Following ablation, patients were routinely followed at outpatient visits at 1, 3, 6, and 12 mo, and then annually. RESULTS Ten patients, median age 57.9 (interquartile range 48.2-61.7) years, 60% female, met inclusion criteria and were followed for 2.8 (interquartile range 1.4-4.5) years.Two had moderately complex CHD (sinus venosus ASD with partial anomalous pulmonary venous return;aortic coarctation with a persistent left superior vena cava), with the remainder having simple defects. AF was paroxysmal in 8 (80.0%) and persistent in 2 (20.0%) patients. The pulmonary vein anatomy was normal in 6 (60.0%) patients. Four had left common PV (n = 3) and/or 3 right PV (n = 2). Electrical pulmonary vein isolation (PVI) was acutely successful in all. One patient had transient phrenic nerve palsy that recovered during the intervention. No major complication occurred. One year after a single ablation procedure, 6 (60%) patients remained free from AF. One patient with recurrent AF had recovered pulmonary vein conduction and underwent a second PVI procedure. A second patient had ablation of an extra-pulmonary vein trigger for AF. CONCLUSION Cryoballoon ablation for AF is feasible and safe in patients with simple and moderate forms of CHD, with an excellent acute success rate and modest 1-year freedom from recurrent AF.Sylvia Abadir Victor Waldmann Katia Dyrda Mikael Laredo Blandine Mondésert Marc Dubuc Paul Khairy 2019World Journal of Cardiology2019,11,5:3
