The calcium sensitizer drug MCI-154 binds the structural C-terminal domain of cardiac troponin C [PDF]
Biochemistry and Biophysics Reports, 2018 The compound MCI-154 was previously shown to increase the calcium sensitivity of cardiac muscle contraction. Using solution NMR spectroscopy, we demonstrate that MCI-154 interacts with the calcium-sensing subunit of the cardiac troponin complex, cardiac ...

Rationally engineered Troponin C modulates in vivo cardiac function and performance in health and disease [PDF]
Nature Communications, 2016 Heart contraction, which is decreased in disease, is determined by Ca2+binding to troponin C. Here, the authors combine a protein engineering approach with gene therapy to modulate heart contractility in mice with the use of rationally designed Troponin ...

Cardiac Manifestations and Emerging Biomarkers in Multisystem Inflammatory Syndrome in Children (MIS-C): A Systematic Review and Meta-Analysis [PDF]
LifeBackground: Cardiac involvement is a key prognostic factor in multisystem inflammatory syndrome in children (MIS-C), a rare but serious inflammatory condition that typically occurs 2–6 weeks after SARS-CoV-2 infection and is characterized by fever ...

Case report: Increased troponin level in 125 children during COVID-19
Frontiers in Pediatrics, 2023 IntroductionIncrease in cardiac biomarkers during Coronavirus disease 2019 (COVID-19) was frequent regardless of the presence of myocarditis and multisystem inflammatory syndrome in children (MIS-C).

Hypertrophic Cardiomyopathy Mutations of Troponin Reveal Details of Striated Muscle Regulation
Frontiers in Physiology, 2022 Striated muscle contraction is inhibited by the actin associated proteins tropomyosin, troponin T, troponin I and troponin C. Binding of Ca2+ to troponin C relieves this inhibition by changing contacts among the regulatory components and ultimately ...

X-ROS Signaling Depends on Length-Dependent Calcium Buffering by Troponin
Cells, 2021 The stretching of a cardiomyocyte leads to the increased production of reactive oxygen species that increases ryanodine receptor open probability through a process termed X-ROS signaling.

An in silico analysis of troponin I mutations in hypertrophic cardiomyopathy of Indian origin. [PDF]
PLoS ONE, 2013 Hypertrophic Cardiomyopathy (HCM) is an autosomal dominant disorder of the myocardium which is hypertrophied resulting in arrhythmias and heart failure leading to sudden cardiac death (SCD).
