Titin modulation and left ventricular remodelling in chronic primary mitral regurgitation [PDF]

Frontiers in Cardiovascular Medicine
BackgroundLeft ventricular (LV) remodelling in mitral valve prolapse (MVP) is usually induced by chronic mitral regurgitation (MR), however it can also be disproportionate to the volume load, generating the hypothesis of MVP cardiomyopathy.

Effect of titin phosphorylation on degradation of titin from skeletal muscles

Food Science and Human Wellness, 2023
The degradation of titin could make the myofibrillar fragmentation to improve meat tenderization during postmortem. This study aimed to investigate effect of phosphorylation on titin degradation.

Anti-titin antibody is associated with more frequent hospitalization to manage thymoma-associated myasthenia gravis

Frontiers in Neurology, 2022
Background and purposeAnti-titin antibodies are antistriational antibodies associated with thymoma-associated myasthenia gravis (MG). We evaluated whether the patients with anti-titin antibody are more frequently hospitalized to manage thymoma-associated

E3-ligase knock down revealed differential titin degradation by autopagy and the ubiquitin proteasome system

Scientific Reports, 2021
The sarcomere protein titin is a major determinant of cardiomyocyte stiffness and ventricular distensibility. The constant mechanical stress on titin requires well-controlled protein quality control, the exact mechanisms of which have not yet been fully ...

Immunological and Structural Characterization of Titin Main Immunogenic Region; I110 Domain Is the Target of Titin Antibodies in Myasthenia Gravis

Biomedicines, 2023
Myasthenia gravis (MG) is an autoimmune disease caused by antibodies targeting the neuromuscular junction (NJ) of skeletal muscles. The major MG autoantigen is nicotinic acetylcholine receptor.

Titin [PDF]

Circulation, 2001
Studies by Frank, Starling, and colleagues demonstrated that elevations of end-diastolic volume increase cardiac output in working hearts,1 a phenomenon referred to as the Frank-Starling (FS) relationship. It stands as one of earliest descriptions of the importance of diastolic dimensions to systolic function, yet how alterations in sarcomere length ...

Protein Quality Control at the Sarcomere: Titin Protection and Turnover and Implications for Disease Development

Frontiers in Physiology, 2022
Sarcomeres are mainly composed of filament and signaling proteins and are the smallest molecular units of muscle contraction and relaxation. The sarcomere protein titin serves as a molecular spring whose stiffness mediates myofilament extensibility in ...

Graded titin cleavage progressively reduces tension and uncovers the source of A-band stability in contracting muscle

eLife, 2020
The giant muscle protein titin is a major contributor to passive force; however, its role in active force generation is unresolved. Here, we use a novel titin-cleavage (TC) mouse model that allows specific and rapid cutting of elastic titin to quantify ...

Mechanoenzymatics of titin kinase [PDF]

Proceedings of the National Academy of Sciences, 2008
Biological responses to mechanical stress require strain-sensing molecules, whose mechanically induced conformational changes are relayed to signaling cascades mediating changes in cell and tissue properties. In vertebrate muscle, the giant elastic protein titin is involved in strain sensing via its C-terminal kinase domain (TK) at the sarcomeric M ...

Cardiac Titin [PDF]

Circulation, 2010
Titin constitutes the third myofilament of cardiac muscle, with a single giant polypeptide spanning from Z-disk to the M-band region of the sarcomere1 (Fig. 1). The ∼1.0 MDa region in the I-band is extensible and consists of tandemly arranged immunoglobulin (Ig)-like domains that make up proximal (near Z-disk) and distal (near A-I junction) segments ...
