ALKBH5‐Mediated M6A Demethylation of G3BP1 Attenuates Ferroptosis Via Cytoplasmic Retention of YBX1/p53 in Diabetic Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
ALKBH5 promoted G3BP1 expression via m⁶A methylation at sites 142/173. G3BP1 interacts with YBX1 and p53, reducing their nuclear translocation and decreasing p53‐mediated SLC7A11 repression. This inhibites cardiomyocyte ferroptosis and mitigates myocardial damage during diabetic ischemia‐reperfusion injury.

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 ...

Dynamic Studies Of Truncated Troponin Complex Usin Hdx [PDF]

Biophysical Journal, 2009
Troponin is the primary control protein of the cardiac and skeletal muscle contractile apparatus. Troponin is made up of three subunits (TnT, TnI, TnC) and is located on the thin filament together with tropomyosin. The binding of Ca++ to TnC induces conformational changes in troponin leading to muscle contraction, via a regulatory mechanism that ...

FOXM1 Protects Against Myocardial Ischemia‐Reperfusion Injury in Rodent and Porcine Models by Suppressing MKRN1‐Dependent LKB1 Ubiquitination

Advanced Science, EarlyView.
FOXM1 maintains mitochondrial bioenergetic function by inhibiting MKRN1‐mediated ubiquitination of LKB1 in cardiomyocytes. Loss of FOXM1 in cardiomyocytes results in upregulation of MKRN1, which enhances LKB1 ubiquitination and disrupts AMPK signaling and energy metabolism pathways. Conversely, FOXM1 overexpression preserves mitochondrial bioenergetics

Infantile restrictive cardiomyopathy: cTnI-R170G/W impair the interplay of sarcomeric proteins and the integrity of thin filaments.

PLoS ONE, 2020
TNNI3 encoding cTnI, the inhibitory subunit of the troponin complex, is the main target for mutations leading to restrictive cardiomyopathy (RCM). Here we investigate two cTnI-R170G/W amino acid replacements, identified in infantile RCM patients, which ...

Hypertrophic and Dilated Cardiomyopathy-Associated Troponin T Mutations R130C and ΔK210 Oppositely Affect Length-Dependent Calcium Sensitivity of Force Generation

Frontiers in Physiology, 2020
Length-dependent activation of calcium-dependent myocardial force generation provides the basis for the Frank-Starling mechanism. To directly compare the effects of mutations associated with hypertrophic cardiomyopathy and dilated cardiomyopathy, the ...

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

CLINICAL FEATURES AND DIAGNOSTIC ALGORITHMS OF CARDIOMYOPATHIES WITH RESTRICTIVE PHENOTYPE CAUSED BY CARDIAC TROPONIN I AND DESMIN GENES MUTATIONS

Педиатрическая фармакология, 2011
The authors are citing the literature data and share their own experiences of observation of two patients with cardiomyopathy associated with restrictive phenotype caused by mutations in defined genes encoding the synthesis of cardiac troponin I and ...

Aminated graphene nanosheet stimulates the maturation of hiPSCs‐derived cardiomyocytes in vitro and enhances their survival in vivo

BMEMat, EarlyView.
Aminated graphene (G‐NH2) niche matrix plays a pivotal role in precisely manipulating cardiac differentiation and maturation of hiPSCs. The molecular mechanism underlying cardiomyocyte maturation is closely linked to the PDGF‐β signaling pathway. Cardiomyocytes derived from the G‐NH2 matrix exhibit enhanced activity and functionality in vivo.

Impact of Diabetes on Long‐Term Outcomes of Percutaneous Coronary Intervention for Coronary Bifurcation Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Diabetes mellitus (DM) is a well‐known risk factor for cardiovascular diseases, including coronary artery diseases (CAD). Complex percutaneous coronary intervention (PCI) such as PCI for bifurcation lesions often yields poor outcomes, especially in DM patients.
