BCL2-Associated Athanogene 3 (BAG3) gene was identified mutated in patients with dilated cardiomyopathy (DCM), an important cause of heart failure and premature death. BAG3 is a cytoprotective co-chaperonne protein involved in many cellular process with a central role in the maintenance of protostasis. We generated two human induced pluripotent stem cell lines (hiPSc), one carrying the heterozygous, the other the homozygous p.

In 30% of cases, pathogenic variants, essentially private to each patient, are identified in at least one of almost 50 reported genes. Thus, while costly, exons capture-based Next Generation Sequencing (NGS) of a targeted gene panel appears as the best strategy to genetically diagnose DCM.

Mutations in FLNC, one of the three filamin genes in humans, have recently been implicated in dominant cardiomyopathies, but the underlying mechanisms are not well understood. Here, we aimed to use Drosophila melanogaster as a new in vivo model to study these diseases.

Using CRISPR/Cas9-mediated genome edition, we generated here a human induced-pluripotent stem cell (hiPSC) line carrying a heterozygous mutation in exon 2 of SCN5A, which leads to apparition of a premature stop codon.

Moreover, YAP/TAZ signaling plays a role in the progression of cancers and renal damage associated with diabetes. However, whether YAP/TAZ signaling is also implicated in diabetes-associated vascular complications is not known.

We conducted genome-wide association studies and multi-trait analyses in HCM (1,733 cases), DCM (5,521 cases) and nine left ventricular (LV) traits (19,260 UK Biobank participants with structurally normal hearts). We identified 16 loci associated with HCM, 13 with DCM and 23 with LV traits.

This chain of care includes the psychiatry of the liaison, the outpatient clinics as well as and day hospital care and extends from the prenatal period to the child's five years, with a focus on the relationship between child and caregivers, as well as an individual perspective on the child. Herein, we present and describe the different units and their functioning emphasizing the synergies and collaborations put in place that ensure the best possible continuity for patients and their families by promoting as much as possible the therapeutic alliance in this chain of care.

We assessed the uptake of fluorescent Lp(a) in primary human lymphocytes as well as Lp(a) hepatic capture in a mouse model in which endogenous hepatocytes have been ablated and replaced with human ones.

Exacerbated postprandial hypertriglyceridemia (PP-HTG) and metabolic context both modulate the overall efficacy of the reverse cholesterol transport (RCT) pathway, but the specific contribution of exaggerated PP-HTG on RCT efficacy remains indeterminate.
View Article and Find Full Text PDFAims: Desmoglein-2 (DSG2) mutations, which encode a heart-specific cadherin crucial for desmosomal adhesion, are frequent in arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D). DSG2 mutations have been associated with higher risk of biventricular involvement. Among DSG2 mutations, mutations of the inhibitory propeptide consensus cleavage-site (Arg-X-Arg/Lys-Arg), are particularly frequent.

Background: The BAG3 (BLC2-associated athanogene 3) gene codes for an antiapoptotic protein located on the sarcomere Z-disc. Mutations in BAG3 are associated with dilated cardiomyopathy (DCM), but only a small number of cases have been reported to date, and the natural history of BAG3 cardiomyopathy is poorly understood.
Objectives: This study sought to describe the phenotype and prognosis of BAG3 mutations in a large multicenter DCM cohort.

Purpose: The efficacy of assertive community treatment for children and adolescents is proven in the United States, but remains controversial in Europe. Moreover, most studies showing positive outcomes of assertive community treatment are limited to statistically significant differences and do not consider whether the treatment is also subjectively clinically meaningful for the patient. Using a naturalistic sample, the present study aims to assess statistical and clinical significance of an assertive community treatment unit for adolescents in Europe.
