Ankyrin G organizes membrane components to promote coupling of cell mechanics and glucose uptake.

Nat Cell Biol 2021 May 10. Epub 2021 May 10.

Department of Biochemistry, University of Iowa Roy J. and Lucille A. Carver College of Medicine, Iowa City, IA, USA.

The response of cells to forces is critical for their function and occurs via rearrangement of the actin cytoskeleton. Cytoskeletal remodelling is energetically costly, yet how cells signal for nutrient uptake remains undefined. Here we present evidence that force transmission increases glucose uptake by stimulating glucose transporter 1 (GLUT1). Read More

Epigenetic Regulation of Cardiac Neural Crest Cells.

Front Cell Dev Biol 2021 21;9:678954. Epub 2021 Apr 21.

Department of Genetics, The University of Alabama at Birmingham, Birmingham, AL, United States.

The cardiac neural crest cells (cNCCs) is a transient, migratory cell population that contribute to the formation of major arteries and the septa and valves of the heart. Abnormal development of cNCCs leads to a spectrum of congenital heart defects that mainly affect the outflow region of the hearts. Signaling molecules and transcription factors are the best studied regulatory events controlling cNCC development. Read More

Therapy of supraventricular and ventricular arrhythmias in adults with congenital heart disease-narrative review.

Cardiovasc Diagn Ther 2021 Apr;11(2):550-562

Department of Cardiology II - Electrophysiology, University Hospital Muenster, Cardiology, Muenster, Germany.

Arrhythmias are among the most common late complications in adults with congenital heart disease (ACHD) and a frequent reason for hospital admission. Both, supraventricular and ventricular arrhythmias, not only cause debilitating symptoms, but may be life-threatening by increasing risk of stroke, causing or worsening heart failure and being associated with sudden death. Substrate and risk for arrhythmia differs widely between congenital defects with specific arrhythmias being much more common in some patients than others. Read More

Narrative review of: risk stratification and implantable cardioverter-defibrillator therapy in adults with congenital heart disease.

Cardiovasc Diagn Ther 2021 Apr;11(2):538-549

Department of Cardiology II - Electrophysiology, University Hospital Muenster, Muenster, Germany.

Fortunately, the population of adults with congenital heart disease (ACHD) is growing due to improved operation techniques. Life expectancy is continuously rising, nevertheless, sudden cardiac death is one of the leading causes of mortality in ACHD late after initial diagnosis. Risk stratification in ACHD remains challenging as large study results are missing, congenital defects and operation methods differ considerably between individual patients and results from acquired heart diseases are often not conferrable.

A new ECG sign for sudden death: Transient prolonged QT interval following premature contraction.

Zhong Nan Da Xue Xue Bao Yi Xue Ban 2021 Apr;46(4):444-448

Department of Cardiology, Third Xiangya Hospital, Central South University, Changsha 410013, China.

Early recognition and treatment for early warning electrocardiogram (ECG) of sudden death are very important to prevent and treat malignant arrhythmia and sudden death. Previous studies have found that R-on-T and T wave alternation, and QT interval prolongation are closely related to malignant arrhythmia or sudden death, which are included in the critical value of ECG.By analyzing the ECG characteristics of 4 patients with sudden death, we found that although the causes of the patients were different, there were transient prolongation of QT interval after premature contraction in 12 lead ECG, followed by malignant arrhythmia or sudden death.

Transcatheter closure has been widely accepted as a highly effective way to treat abnormal blood flows and/or embolization of thrombus in the heart. It allows the closure of four types of congenital heart defects (CHDs) and stroke-associated left atrial appendage (LAA). The four types of CHDs include atrial septal defect (ASD), patent foramen ovale (PFO), patent ductus arteriosus (PDA), and ventricular septal defect (VSD). Read More

Genetic evaluation of newborns with critical congenital heart defects admitted to the intensive care unit.

Eur J Pediatr 2021 May 7. Epub 2021 May 7.

Department of Clinical Genetics, University Children's Hospital, Belgrade, Serbia.

Rapid and efficient diagnostics is crucial for newborns with congenital heart defects (CHD) in intensive care unit (ICU) but is often challenging. Given that genetic factors play a role in 20-30% cases of CHD, it is likely that genetic tests could improve both its speed and efficiency. We aimed to analyze the utility of rapid and cost-effective multiplex ligation dependent probe amplification analysis (MLPA) for chromosomal analysis in newborns with critical CHD. Read More

Genetics of canine subvalvular aortic stenosis (SAS).

Canine Med Genet 2021 May 7;8(1). Epub 2021 May 7.

Department of Medicine and Epidemiology, School of Veterinary Medicine, University of California Davis, Davis, CA, 95616, USA.

Subvalvular aortic stenosis (SAS) is one of the most common congenital heart defects of dogs. The disease is characterized by obstruction of the left ventricular outflow tract, resulting in pressure overload on the left ventricle. The etiology of obstruction is a fibromuscular nodule, ridge, or ring of tissue that increases aortic outflow tract velocity. Read More

Toward Eliminating Perinatal Comfort Care for Prenatally Diagnosed Severe Congenital Heart Defects: A Vision.

Mayo Clin Proc 2021 05;96(5):1276-1287

Division of Maternal-Fetal Medicine, Mayo Clinic, Rochester, MN.

Over the past 40 years, the medical and surgical management of congenital heart disease has advanced considerably. However, substantial room for improvement remains for certain lesions that have high rates of morbidity and mortality. Although most congenital cardiac conditions are well tolerated during fetal development, certain abnormalities progress in severity over the course of gestation and impair the development of other organs, such as the lungs or airways.

Physiology, Biophysics and Systems Biology Program, Weill Cornell Medicine, New York, NY, 10021, USA; Arthritis and Tissue Degeneration Program, Hospital for Special Surgery, New York, NY, 10021, USA; Institute for Advanced Study, Technische Universität München, D-85748 Garching, Germany; Department of Medicine, Physiology and Systems Biology, Weill Cornell Medicine, New York, NY, 10021, USA; Department of Biophysics, Physiology and Systems Biology, Weill Cornell Medicine, New York, NY 10021, USA. Electronic address:

A disintegrin and metalloprotease 17 (ADAM17) is a cell-surface metalloprotease that serves as the principle sheddase for Tumor necrosis factor α (TNFα), interleukin-6 receptor (IL-6R) and several ligands of the epidermal growth factor receptor (EGFR), regulating these crucial signaling pathways. ADAM17 activation requires its transmembrane domain, but not its cytoplasmic domain, and little is known about the role of this domain in vivo. To investigate, we used CRISPR-Cas9 to mutate the endogenous Adam17 locus in mice to produce a mutant ADAM17 lacking its cytoplasmic domain (Adam17Δcyto). Read More

Discordant congenital heart defects in monochorionic twins: Risk factors and proposed pathophysiology.

PLoS One 2021 6;16(5):e0251160. Epub 2021 May 6.

David Geffen School of Medicine, UCLA, Los Angeles, California, United States of America.

A six-fold increase in congenital heart defects (CHD) exists among monochorionic (MC) twins compared to singleton or dichorionic twin pregnancies. Though MC twins share an identical genotype, discordant phenotypes related to CHD and other malformations have been described, with reported rates of concordance for various congenital anomalies at less than 20%. Our objective was to characterize the frequency and spectrum of CHD in a contemporary cohort of MC twins, coupled with genetic and clinical variables to provide insight into risk factors and pathophysiology of discordant CHD in MC twins.

Notch regulates vascular collagen IV basement membrane through modulation of lysyl hydroxylase 3 trafficking.

Angiogenesis 2021 May 6. Epub 2021 May 6.

Department of Biological Sciences, University of Denver, Denver, CO, 80210, USA.

Collagen type IV (Col IV) is a basement membrane protein associated with early blood vessel morphogenesis and is essential for blood vessel stability. Defects in vascular Col IV deposition are the basis of heritable disorders, such as small vessel disease, marked by cerebral hemorrhage and drastically shorten lifespan. To date, little is known about how endothelial cells regulate the intracellular transport and selective secretion of Col IV in response to angiogenic cues, leaving a void in our understanding of this critical process.
