Standardization of troponin I measurements : an update

, 2008
Standardization of cardiac troponin I (cTnI) measurement is important because of the central role for diagnosis of myocardial infarction. In blood, cTnI is present as a heterogeneous mixture of different molecular species.

Troponin destabilization impairs sarcomere-cytoskeleton interactions in iPSC-derived cardiomyocytes from dilated cardiomyopathy patients

, 2020
The sarcomeric troponin-tropomyosin complex is a critical mediator of excitation-contraction coupling, sarcomeric stability and force generation. We previously reported that induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) from patients ...

DDX3x Regulates NINJ1 Transcription via Histone Lactylation in Sepsis Associated‐Acute Kidney Injury

Advanced Science, EarlyView.
This study identifies a potential therapeutic approach for sepsis‐associated acute kidney injury (SA‐AKI). We found that during SA‐AKI, reduced expression of DDX3x in renal tubular epithelial cells mediates histone delactylation, which in turn upregulates NINJ1 transcription and triggers tubular cell death. Conversely, Odetiglucan confers protection by

Immunization of Mice with Anthrax Protective Antigen Limits Cardiotoxicity but Not Hepatotoxicity Following Lethal Toxin Challenge

Toxins, 2015
Protective immunity against anthrax is inferred from measurement of vaccine antigen-specific neutralizing antibody titers in serum samples. In animal models, in vivo challenges with toxin and/or spores can also be performed.

Value of Troponin Testing for Detection of Heart Disease in Previously Healthy Children

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Troponin levels are frequently obtained in pediatric patients, but the benefit remains unclear. Methods and Results This retrospective study included 1993 patients aged 0 to 21 years without history of cardiac disease in whom troponin levels ...

Phosphorylation of the ‘37000 component’ of the troponin complex (troponin-T) [PDF]

Biochemical Journal, 1973
Most of the phosphorus present in the troponin complex, which on average contains 1 mol of P/80000g, is associated with the ‘37000 component’ (0.6mol of P/mol). The inhibitory protein and particularly the ‘37000 component’, but not the calcium-binding protein, were phosphorylated when incubated with phosphorylase b kinase and [γ-32P]ATP.

Senile Systemic Amyloidosis: Clinical Features at Presentation and Outcome [PDF]

, 2013
Background Cardiac amyloidosis is a fatal disease whose prognosis and treatment rely on identification of the amyloid type. In our aging population transthyretin amyloidosis (ATTRwt) is common and must be differentiated from other amyloid types.

Nucleoside‐Modified mRNA Encoding Alpha‐Galactosidase A Ameliorates Fabry Disease Phenotypes in Human IPSC‐Derived Cardiomyocytes

Advanced Science, EarlyView.
Human iPSC‐derived Fabry cardiomyocytes exhibited broad transcriptional dysregulation, apoptosis, mitochondrial dysfunction, impaired reactive oxygen species handling, altered contractility, and abnormal calcium transient decay, potentially mediated by phospholamban hyperphosphorylation.

CDK4/MERCs/PINK1 Axis Drives PFOA/HFPO‐TA‐Induced Cardiac Senescence via Mitophagy Defect and cGAS‐STING Activation: In Vitro Amelioration by Cycloastragenol

Advanced Science, EarlyView.
The present study demonstrated that PFOA and HFPO‐TA exposure suppressed CDK4, disrupted MERCs and impaired PINK1/Parkin‐mediated mitophagy, thereby accelerating cardiac senescence, whereas CAG effectively reversed these pathological changes in vitro. Our findings identify CDK4 as a critical regulator bridging mitophagy defects and cardiac senescence ...
