The underlying mechanisms responsible for the cardioprotective effects of riboflavin remain elusive. Current study tested the hypothesis that riboflavin protects injured myocardium via epigenetic modification of LSD1. Here we showed that myocardial injury was attenuated and cardiac function was
Pathological remodeling is the main detrimental complication after myocardial infarction (MI). Overproduction of reactive oxygen species (ROS) in infarcted myocardium may contribute to this process. Adequate exercise training after MI may reduce oxidative stress-induced cardiac tissue damage and
Protein quality control (PQC) in the heart plays an important role to maintain cellular protein homeostasis. Impairment of PQC may cause the development of heart failure. It is well known that histone deacetylase 6 (HDAC6) is an essential enzyme for regulating the cellular PQC response. In this
Background: This study tested the hypothesis that combined histone methyltransferase G9a inhibitor (i.e., UNC0638) and erythropoietin (EPO) was superior to either one alone for protecting myocardium from acute myocardial infarction (AMI)
Despite the fact that histone deacetylase (HDAC) inhibitors have been tested to treat various cardiovascular diseases, the effects of selective HDAC6 inhibitor ACY1215 on infarct size during cardiac ischemia-reperfusion (IR) injury still remain unknown. In the present study we aimed to Left ventricular (LV) remodeling, after myocardial infarction (MI), can result in LV dilation and LV pump dysfunction. Post-MI induction of matrix metalloproteinases (MMPs), particularly MMP-2 and MMP-9, have been implicated as causing deleterious effects on LV and extracellular matrix remodeling in
OBJECTIVE
Histone deacetylases (HDACs) play a critical role in the regulation of gene transcription, cardiac development, and diseases. The aim of this study was to investigate whether the inhibition of HDACs improves cardiac remodeling and its underlying mechanisms in a mouse myocardial infarction
BACKGROUND
Left ventricular (LV) remodeling after myocardial infarction is associated with hypertrophy of surviving myocytes and represents a major process that leads to heart failure. One of the intrinsic histone acetyltransferases, p300, serves as a coactivator of hypertrophy-responsive
BACKGROUND
A natural p300-specific histone acetyltransferase (HAT) inhibitor, curcumin, may have therapeutic potential for heart failure. However, it is unclear whether curcumin exhibits beneficial additive or synergistic effects on conventional therapy with angiotensin-converting enzyme inhibitors
OBJECTIVE
To observe the co-variation of acetylated histone H3 levels of peripheral blood mononuclear cells (PBMCs) and onset time of acute ischemic stroke and examine the histone H3 acetylation levels in PBMCs of acute cerebral infarction patients with different stroke subtypes and injury
Histone acetylation and deacetylation are among the most important epigenetic processes that regulate gene expression. Nonselective inhibitors of histone deacetylases (HDAC) can protect brain cells during ischemia and stroke. However, which HDAC isoform is involved in this effect is unknown. Some
Myocardial infarction (MI) dampens heart function and poses a great health risk. The class III deacetylase sirtuin 1 (SIRT1) is known to confer cardioprotection. SIRT1 expression is downregulated in the heart by a number of stress stimuli that collectively drive the pathogenesis of MI, although the
While inhibition of class I/IIb histone deacetylases (HDACs) protects the mammalian heart from ischemia reperfusion (IR) injury, class selective effects remain unexamined. We hypothesized that selective inhibition of class I HDACs would preserve left ventricular contractile function following IR in
An experimental kidney infarction model was developed in the mouse to study the uptake of a radiolabeled monoclonal antibody previously shown to bind to degenerating cells in malignant tumors. To determine if this approach is applicable to normal tissue and cell degeneration, kidney infarction was
Background Coronary microvascular dysfunction is common in patients of myocardial infarction with non-obstructive coronary artery disease. Coronary flow reserve (CFR) reflects coronary microvascular function and is a powerful independent index of coronary microvascular dysfunction and heart failure.
