Proteolytic Activity of Zingiber officinale Extract: Interaction With Myofibrillar Proteins of Different Origins and Functional Effects in Meat Systems [PDF]

Food Sci Nutr
Ginger‐derived proteases were evaluated for their proteolytic activity toward isolated chicken and pork myofibrils and their effects during meat marination. The ginger extract showed a selective and moderate proteolytic activity, resulting in controlled protein degradation and improved meat quality, including tenderness, juiciness, flavor, and overall ...

Mechanical and kinetic effects of shortened tropomyosin reconstituted into myofibrils [PDF]

, 2009
The effects of tropomyosin on muscle mechanics and kinetics were examined in skeletal myofibrils using a novel method to remove tropomyosin (Tm) and troponin (Tn) and then replace these proteins with altered versions.

Assembly and Maintenance of Myofibrils in the Heart

Cytoskeleton, EarlyView.
ABSTRACT The assembly of actin and myosin to the paracrystalline arrangement of myofibrils in striated muscle, that is, heart and skeletal, has puzzled many a cell biologist. Different models, based on cultured cardiomyocytes, were proposed for the last 30 years to explain the sequence of events.

Effects of low-load resistance training with blood flow restriction on muscle fiber myofibrillar and extracellular area

Frontiers in Physiology
Blood flow restriction applied during low-load resistance training (LL-BFR) induces a similar increase in the cross-sectional area of muscle fibers (fCSA) compared to traditional high-load resistance training (HL-RT).

POSTTRANSLATIONAL INCORPORATION OF CONTRACTILE PROTEINS INTO MYOFIBRILS IN A CELL-FREE SYSTEM [PDF]

, 1988
The incorporation of newly synthesized protein into myofibrils has been examined in a cell-free system. Myofibrils were added to a reticulocyte lysate after the in vitro translation of muscle-specific poly(A)+RNA.

Increased Insulin Action, Glucose Metabolism and Muscle Function in Supervillin‐Knockout and Supervillin‐Mutant Mice

Cytoskeleton, EarlyView.
ABSTRACT We here describe mouse models with complementary homozygous Svil mutations. In skeletal muscle, Svil‐Mut mice express the Svil‐encoded N‐terminus fused to the βgal‐neo gene‐trap tag and lack the highly conserved archvillin C‐terminus; Svil‐KO mice lack expression of all known Svil‐encoded proteins; and Svil‐LoxP mice contain loxP sites for ...

Morphometric Analysis of Human Embryonic Stem Cell-Derived Ventricular Cardiomyocytes: Determining the Maturation State of a Population by Quantifying Parameters in Individual Cells

Stem Cells International, 2015
Quantitative methods were established to determine the level of maturation of human embryonic stem cell-derived ventricular cardiomyocytes (hESC-vCMs) that were treated with different metabolic stimulants (i.e., isoproterenol and oleic acid) during early

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 ...

Theoretical considerations on myofibril stiffness

Biophysical Journal, 1997
A discrete model of the interaction between individual myofilaments was developed to study the stiffness of a sarcomere for the case in which filament compliance is not negligible. Our model retains, in the limit, the characteristics of the previously published model by Ford et al. (Ford, L. E., A. F. Huxley, and R. M. Simmons. 1981.

Assembly and Disassembly of Myofibrils in Dissociated Cardiomyocytes [PDF]

, 2012
Significance 1) We have developed a hybrid TPEF-SHG imaging system with an onstage incubator for long-term living-cell imaging. Using the imaging system, the assembly of myosin filaments onto the myofibrils can be investigated without fluorescently
