Spotlight on the Nucleotide: Solid‐State NMR for the Investigation of ATP Hydrolysis in the ATPase SmsC

Chemistry – A European Journal, EarlyView.
Nucleotide‐detected solid‐state NMR has been applied to probe nucleotide conformations and dynamics during ATP hydrolysis using the dimeric P‐loop ATPase SmsC as a model protein. The different stages of ATP hydrolysis have been mimicked by ATP analogues for which different degrees of conformational heterogeneity have been observed. ABSTRACT Solid‐state

Disentangling Sex Differences in Sulfonylurea Drug Response With Genome‐Wide Association Studies in Individuals With Type 2 Diabetes

Clinical Pharmacology &Therapeutics, EarlyView.
A sex‐stratified genome‐wide association study of sulfonylurea response identified sex‐specific genetic loci associated with HbA1c reduction in individuals with type 2 diabetes. Replication and functional validation supported a male‐specific association at the TMEM64/NECAB1 locus, highlighting the potential of sex‐informed pharmacogenomics to advance ...

A protein interaction mechanism for suppressing the mechanosensitive Piezo channels

Nature Communications, 2017
Mechanosensitive Piezo channels are important for a wide range of mechanotransduction processes. Here the authors show that Piezos interact with sarcoplasmic /endoplasmic-reticulum Ca2+ ATPases (SERCA) and give mechanistic insights into mechanogating and

Cardiac muscle thin filament structures reveal calcium regulatory mechanism

Nature Communications, 2020
The contraction of cardiac and skeletal muscles is regulated by Ca2+ released from the sarcoplasmic reticulum in muscle cells. Here the authors provide molecular insights into Ca2+ regulation of muscle contraction by determining the cryo-EM structures of

Fhod3 in zebrafish supports myofibril stability during growth of embryonic skeletal muscle

Developmental Dynamics, EarlyView.
Abstract Background Actin filament organization in cardiomyocytes critically depends on the formin Fhod3, but a role for Fhod3 in skeletal muscle development has not yet been described. Results We demonstrate here that in zebrafish mutated for one of two fhod3 paralog genes, fhod3a, skeletal muscle of the trunk appears normal through 2 days post ...

A Calsequestrin-1 Mutation Associated with a Skeletal Muscle Disease Alters Sarcoplasmic Ca2+ Release.

PLoS ONE, 2016
An autosomal dominant protein aggregate myopathy, characterized by high plasma creatine kinase and calsequestrin-1 (CASQ1) accumulation in skeletal muscle, has been recently associated with a missense mutation in CASQ1 gene.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Emerging Evidence for cAMP-calcium Cross Talk in Heart Atrial Nanodomains Where IP-Evoked Calcium Release Stimulates Adenylyl Cyclases

Contact, 2021
Calcium handling is vital to normal physiological function in the heart. Human atrial arrhythmias, eg. atrial fibrillation, are a major morbidity and mortality burden, yet major gaps remain in our understanding of how calcium signaling pathways function ...

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

The sarcoplasmic reticulum [PDF]

BioArchitecture, 2011
Skeletal muscle exhibits strikingly regular intracellular sorting of actin and tropomodulin (Tmod) isoforms, which are essential for efficient muscle contraction. A recent study from our laboratory demonstrates that the skeletal muscle sarcoplasmic reticulum (SR) is associated with cytoplasmic γ-actin (γ(cyto)-actin) filaments, which are predominantly ...
