Molecular Basis of Diastolic Dysfunction [PDF]

Heart Failure Clinics, 2008
Diastolic dysfunction is characterized by prolonged relaxation, increased filling pressure, decreased contraction velocity, and reduced cardiac output. Phenotypical features of diastolic dysfunction can be observed at the level of the isolated myocyte.

Activation of Spinal Astrocyte α2A Adrenoceptors Protects Against Sepsis‐Induced Heart Injury Through Inhibition of GABAergic Neuronal Necroptosis

Advanced Science, EarlyView.
The study in this paper found that activating the α2A receptors of astrocytes in the thoracic spinal cord can reduce the release of inflammatory factors, thereby decreasing the necroptosis of GABAergic neurons and consequently alleviating myocardial injury caused by sepsis.

ER‐phagy Activation by AMFR Attenuates Cardiac Fibrosis Post‐Myocardial Infarction via mTORC1 Pathway

Advanced Science, EarlyView.
By catalyzing FAM134B ubiquitination and activating ER‐phagy, AMFR alleviates progressive fibrosis and cardiac dysfunction by inhibiting the mTORC1 pathway. Consequently, these findings underscore the essential role of AMFR‐driven ER‐phagy in mitigating the progression of fibrotic responses, offering a potential therapeutic target for preventing heart ...

Inhibition of AMPKα Pathway by Podocyte GOLM1 Exacerbates Diabetic Nephrology in Mice

Advanced Science, EarlyView.
Podocyte Golgi membrane protein 1 interacts with epidermal growth factor receptor to inhibit peroxisome proliferator activated receptor γ, and then inactivates adenosine monophosphate activated protein kinase α pathway, which facilitates diabetes‐related inflammation, oxidative damage, apoptosis, and renal dysfunction.

Mitochondrial Transplantation Augments the Reparative Capacity of Macrophages Following Myocardial Injury

Advanced Science, EarlyView.
Mitochondrial transplantation induces macrophage polarization toward an anti‐inflammatory M2 phenotype, enhances their reparative capacities, and facilitates mitochondrial transfer to cardiomyocytes, collectively promoting tissue repair and functional recovery post‐myocardial infarction.

Diastolic dysfunction in sickle cell

Blood, 2010
In adults with sickle cell disease (SCD), echocardiographic evidence of diastolic dysfunction is an independent risk factor for death that is additive to pulmonary hypertension. In this issue of Blood, Johnson and colleagues describe echocardiography and polysomnography results from 44 children with SCD.

LncRNA Foxo6os as a Novel “ Scaffold” Mediates MYBPC3 in Combating Pathological Cardiac Hypertrophy and Heart Failure

Advanced Science, EarlyView.
Schematic overview showing that forkhead box O6, opposite strand (Foxo6os) acts as a “scaffold”, directly binding myosin‐binding protein‐C (MYBPC3) and recruiting protein kinase C (PKC‐α) to mediate site‐specific phosphorylation of MYBPC3. This post‐translational modification supports cardiac contraction by regulating L‐type Ca2+ channels, especially ...

Loss of Hepatic Angiotensinogen Attenuates Diastolic Dysfunction in Heart Failure with Preserved Ejection Fraction

Advanced Science, EarlyView.
Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.

Atrial Fibroblasts‐Derived Extracellular Vesicles Exacerbate Atrial Arrhythmogenesis

Advanced Science, EarlyView.
Exosome miR‐224‐5p derived from angiotensin II‐treated atrial fibroblasts creates a substrate for AF by promoting atrial electrical remodeling. Increased exosome miR‐224‐5p enhances AF susceptibility by inhibiting CACNA1c expression and decreasing ICa current of atrial cardiomyocytes.
