Converter domain mutations in myosin alter structural kinetics and motor function.

J Biol Chem 2018 Dec 5. Epub 2018 Dec 5.

Cellular and Molecular Physiology, Penn State University College of Medicine, United States.

Myosins are molecular motors that use a conserved ATPase cycle to generate force. We investigated two mutations in the converter domain of myosin V (R712G and F750L) to examine how altering specific structural transitions in the motor ATPase cycle can impair myosin mechanochemistry. The corresponding mutations in the human beta-cardiac myosin gene are associated with hypertrophic and dilated cardiomyopathy, respectively. Read More

Prenatal MR imaging features of Caroli syndrome in association with autosomal recessive polycystic kidney disease.

Radiol Case Rep 2019 Feb 26;14(2):265-268. Epub 2018 Nov 26.

Department of Radiology, The Children's Hospital of Philadelphia, 34th Street and Civic Center Boulevard, Philadelphia, PA 10104, USA.

Caroli syndrome, which is characterized by saccular and fusiform dilatation of the biliary ducts, is usually observed in association with autosomal recessive polycystic kidney disease (ARPKD). Although the diagnosis of ARPKD is generally easy to make in postnatal ultrasound, the diagnosis of Caroli syndrome may be challenging in prenatal ultrasound. Herein, we present a case of a 29-week fetus with ARPKD associated with Caroli syndrome in whom fetal magnetic resonance imaging was essential to identify the "central dot sign" within the dilated biliary ducts to confirm the prenatal diagnosis of Caroli syndrome and to increase our level of confidence in this diagnosis.

YAP activation promotes the transdifferentiation of cardiac fibroblasts to myofibroblasts in matrix remodeling of dilated cardiomyopathy.

Braz J Med Biol Res 2018 Nov 23;52(1):e7914. Epub 2018 Nov 23.

Department of Cardiology, Huashan Hospital, Fudan University, Shanghai, China.

Yes-associated protein (YAP) is an important regulator of cellular proliferation and transdifferentiation. However, little is known about the mechanisms underlying myofibroblast transdifferentiation in dilated cardiomyopathy (DCM). We investigated the role of YAP in the pathological process of cardiac matrix remodeling. Read More

Kinetics of selected serum markers of fibrosis in patients with dilated cardiomyopathy and different grades of diastolic dysfunction of the left ventricle.

Cardiol J 2018 Nov 28. Epub 2018 Nov 28.

Collegium Medicum of Jagiellonian University, Department of Cardiac and Vascular Diseases, John Paul II Hospital, Kraków, Poland, ul.Prądnicka 80, 31-202 Cracow, Poland.

Background: Fibrosis of the extracellular matrix (ECM) in dilated cardiomyopathy (DCM) is common and compromises both systolic and diastolic function. The aim of this study was to investigate the kinetics of ECM fibrosis markers over a 12 month follow-up in patients with DCM based on the severity of diastolic dysfunction (DD).

Methods: Seventy consecutive DCM patients (48 ± 12. Read More

Alström Syndrome Presenting as Isolated Dilated Cardiomyopathy.

Indian J Pediatr 2018 Nov 28. Epub 2018 Nov 28.

Department of Medical Genetics, Nizam's Institute of Medical Sciences, Hyderabad, Telangana, India.

Cardiomyopathy is an etiologically heterogeneous condition, and non-syndromic as well as syndromic genetic causes are identified in a significant proportion of cases without a known acquired cause. The present report describes a 2-mo-old boy who presented initially with a referral diagnosis of isolated dilated cardiomyopathy, without any associated dysmorphism or malformations, and with history of similar cardiac disease and early infantile death in an elder male sibling. Next generation sequencing (NGS) based multigene panel testing of the cardiomyopathy-associated genes was done which revealed the diagnosis of Alström syndrome, based on which appropriate management and surveillance could be planned for the child and accurate genetic counseling could be provided to the parents.

Arrhythmic Genotypes in Familial Dilated Cardiomyopathy: Implications for Genetic Testing and Clinical Management.

Heart Lung Circ 2018 Oct 11. Epub 2018 Oct 11.

Molecular Cardiology Division, Victor Chang Cardiac Research Institute, Sydney, NSW, Australia; St. Vincent's Clinical School, Faculty of Medicine, University of New South Wales, Sydney, NSW, Australia; Cardiology Department, St. Vincent's Hospital, Sydney, NSW, Australia. Electronic address:

Cardiac arrhythmias are frequently seen in patients with dilated cardiomyopathy (DCM) and can precipitate heart failure and death. In patients with non-ischaemic DCM, evidence for the benefit of an implantable cardioverter-defibrillator (ICD) for primary prevention of sudden cardiac death has recently been questioned. Algorithms devised to identify high-risk individuals who might benefit most from ICD implantation have focussed on clinical criteria with little attention paid to the underlying aetiology of DCM.

Clinical profile and outcome of cardiac involvement in MELAS syndrome.

Int J Cardiol 2018 Oct 23. Epub 2018 Oct 23.

Department of Inherited Neuro-metabolic Disorders, Anna Meyer Children's Hospital, viale Pieraccini 24, 50159 Florence, Italy. Electronic address:

Background: Mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like (MELAS) syndrome is a rare condition with heterogeneous clinical presentation. Cardiac involvement commonly develops during adulthood, comprising both structural and conduction/arrhythmic abnormalities; early paediatric onset has rarely been reported. We describe the clinical profile, outcome and clinical implication of MELAS-associated cardiomyopathy at a tertiary referral centre. Read More
