M.B. was funded by a Wellcome Trust Senior Investigator Award to P. Lawrence (WT096645MA).Muscle differentiation requires the assembly of high-order structures called myofibrils, composed of sarcomeres.

Sarcomeres are the basic contractile units within cardiac myocytes, and the collective shortening of sarcomeres aligned along myofibrils generates the force driving the heartbeat.

Myofibrils of skeletal muscle: the activity coefficient of orthophosphate.
In the myofibrils of skeletal muscle, at 22°C, pH 7.1 and at the physiological protein osmotic pressure of 1.8 x 105 dynes/cm2, orthophosphate behaves quite ideally, the activity coefficient being 0.85.

Myofibrils put the squeeze on nuclei [PDF]
During muscle development, nuclei travel from the centre of the myofibre to the periphery, a process defective in certain diseases. A new study reveals that this movement is due to centripetal forces imposed on nuclei by the crosslinking and contraction of myofibrils.

Early Clinical, Imaging, and Pathological Characteristics of SRPK3/TTN‐Digenic Myopathy
ABSTRACT Objective SRPK3/TTN‐digenic myopathy was recently established as a skeletal muscle myopathy caused by digenic inheritance. This study characterizes the early clinical presentation of SRPK3/TTN‐digenic myopathy in one previously reported and seven newly identified pediatric patients.

Myofibril diameter is set by a finely tuned mechanism of protein oligomerization in Drosophila
Myofibrils are huge cytoskeletal assemblies embedded in the cytosol of muscle cells. They consist of arrays of sarcomeres, the smallest contractile unit of muscles.

A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Contractile Properties of Human Fetal Skeletal Myofibrils
Congenital contractures such as clubfoot are present in ?1/250 live births. Several congenital contractures syndromes are caused by mutations in genes that code for skeletal myofilament proteins, including MYH3 and MYH8.

Accessibility of myofilament cysteines and effects on ATPase depend on the activation state during exposure to oxidants. [PDF]
Signaling by reactive oxygen species has emerged as a major physiological process. Due to its high metabolic rate, striated muscle is especially subject to oxidative stress, and there are multiple examples in cardiac and skeletal muscle where oxidative ...
