MiR-144 affects proliferation and apoptosis of high glucose-induced AC16 cardiomyocytes by regulating CTRP3/JNK signaling.

CONCLUSION: MiR-144 regulates proliferation and apoptosis of HG-induced AC16 cardiomyocytes through targeting the CTRP3/JNK signaling pathway, providing a novel avenue for treatment of DCM. PMID: 32211094 [PubMed]

In conclusion, the impaired in situ activity of RyR2 may also account for the poor overall cardiac outcome reported in MetS patients; hence, the SERCA pump and RyR2 are both attractive potential targets for future therapies. Introduction Metabolic syndrome (MetS) is a cluster of biochemical and physiological risk factors for cardiovascular disease and diabetes mellitus type 2 (DM2); it represents a severe public health problem around the world (Alberti et al., 2009). Risk factors for MetS include obesity (particularly central obesity), elevated triglyceride (TG) levels, low high-density lipoprotein cholesterol (HDL...

Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health probl...

AbstractPurpose of ReviewDue to advancements in oncologic treatment strategies and techniques, the number of survivors who have undergone hematopoetic stem cell transplant (HCT) continues to increase in the United States; this number is projected to reach 502,000 by the year 2030. There is significant interest within the field of cardio-oncology to identify cardiotoxicity and cardiovascular disease in the HCT population. Epidemiologic studies analyzing both short- and long-term cardiovascular effects, risk stratification modeling, cardioprotective strategies, and expert consensus documents for cardiotoxicity surveillance r...

Discussion Barth syndrome is characterized by a dilated cardiomyopathy, proximal skeletal muscle weakness, neutropenia and short stature that usually presents at birth or soon after. It is a rare X-linked recessive disease process caused by mutations in the TAZ gene. The TAZ gene codes for tafazzin which alters cardiolipin in mitochondria. Characteristic facies can be seen especially in infancy including a tall and broad forehead, prominent chin and full cheeks, larger ears, and deep-set eyes. Most patients present at birth or soon afterwards but some may not until later in life. Life expectancy is reduced with many childr...

Abstract Friedreich's ataxia (FRDA), which occurs in 1/50000 live births, is the most prevalent inherited neuromuscular disorder. Nearly all FRDA patients develop cardiomyopathy at some point in their lives. The clinical manifestations of FRDA include ataxia of the limbs and trunk, dysarthria, diabetes mellitus, and cardiac diseases. However, the broad clinical spectrum makes FRDA difficult to identify. The diagnosis of FRDA is based on the presence of suspicious clinical factors, the use of the Harding criteria and, more recently, the use of genetic testing for identifying the expansion of a triplet nucleotide se...

Calcium/calmodulin-dependent protein kinase II (CaMKII) is upregulated in diabetes and significantly contributes to cardiac remodeling with increased risk of cardiac arrhythmias. Diabetes is frequently associated with atrial fibrillation, coronary artery disease, and heart failure, which may further enhance CaMKII. Activation of CaMKII occurs downstream of neurohormonal stimulation (e.g. via G-protein coupled receptors) and involve various posttranslational modifications including autophosphorylation, oxidation, S-nitrosylation and O-GlcNAcylation.

Conclusion: The findings of the study showed that NGAL associated with NT-proBNP was a stronger predictor of the primary endpoint than NGAL or NT-proBNP alone. The level of NGAL was rising in hypertension, ischemia, anemia, hypoalbuminemia, diabetes or arrhythmias.Kidney Blood Press Res 2018;43:1865 –1877

Conclusions: Heart remodelling related to a high cardiac output state cardiomyopathy was more pronounced in patients with homozygous β°/β° genotype. Osteoporososis was significantly more frequent in patients with homozygous β°/β° genotype, treated for more than two-thirds with DFO therapy. These data support the knowledge of different phenotypic groups in the management of NTDT patients.TableDisclosuresPepe: Chiesi Farmaceutici S.p.A., ApoPharma Inc., and Bayer: Other: No profit support.

CONCLUSIONS: Cardiac involvement in m.3243A>G carriers has been only rarely systematically studied, which is perhaps why the incidence of cardiac diseases in MELAS is lower than would be expected. Myocardial abnormalities are much more frequent than arrhythmias or conduction defects. All symptomatic and asymptomatic m.3243A>G carriers should be systematically investigated for cardiac disease.
