.... with exercise) is reversible and largely due to cardiomyocyte hypertrophy. Pathological hypertrophy (e.g. with hypertension) is associated with additional features including increased fibrosis and can lead to heart failure. RAF kinases (ARAF/BRAF/RAF1) integrate signals into the extracellular signal-regulated...

... and quantified rat ASC-exosome miRNAs and used bioinformatics to select uncharacterized miRNAs down-regulated in post-MI related to cardiac repair. We selected and validated miR-196a-5p and miR-425-5p as candidates for the concerted response in neonatal cardiomyocytes, cardiac fibroblasts, endothelial cells...

...Fei Xu; Jingcheng Yang; Jun Shang; Feng Lan; Miaomiao Li; Leming Shi; Li Shen; Yongming Wang; Junbo Ge Recent evidence has shown that cardiomyocytes (CMs) can proliferate at a low level after myocardial infarction (MI), but it is insufficient to reestablish heart function. Several microRNAs (miRNAs...

... TOF patients, two of which (Y42D and L659P) are novel and not found in the Exome Aggregation Consortium (ExAC) database. Point mutation knock-in (KI) and ADAM17 knock-out (KO) human embryonic stem cells (hESCs) were generated by CRISPR/Cas9 and programmed to differentiate into cardiomyocytes (CMs...

...Hannah A. Cooper; Satoru Eguchi Ischemia reperfusion (I/R) injury is a common event following myocardial infarction (MI) resulting in excessive oxidative stress, calcium overload, inflammation, and cardiomyocyte death. Mitochondrial homeostasis including their dynamics are imbalanced in cardiac I/R...

... in the left ventricle (LV) in response to internal or external cardiovascular damage or influence by pathogenic risk factors, and is a precursor of clinical heart failure (HF). Pathological remodelling is associated with fibrosis, inflammation and cellular dysfunction (e.g. abnormal cardiomyocyte/non...

... the influence of various agonists or physical stress that, in the long term, also lead to development of hypertrophy. Previously, we identified three different Cl - channel activities in neonatal rat cardiomyocytes: (i) Ca 2+ regulated, (ii) cAMP regulated (cystic fibrosis transmembrane conductance regulator Cl...

... in vivo , as demonstrated by the developmental switching of the major isoform of myosin heavy chain (MHC) from β to α. However, the β-MHC isoform predominates in monocrotaline-induced pulmonary hypertension, a model of right ventricular hypertrophy in vivo . Cultured cardiomyocytes showed a predominance...

... of newborn genetically hypertensive rats. The present study was designed to investigate the participation of phospholipase A 2 in these modifications. 2. Phospholipase A 2 activity of cultured cardiomyocytes of neonate spontaneously hypertensive rats and normotensive control Wistar—Kyoto rats was compared...
