Skeletal muscle‐specific myostatin overexpression promotes muscle oxidative capacity and fatigue resistance in transgenic mice

Experimental Physiology, Volume 111, Issue 7, Page 3357-3380, 1 July 2026.
Abstract In addition to controlling muscle mass, myostatin may support oxidative metabolism and endurance. Loss of function through gene knockout or post‐natal blockade generally lowers muscle oxidative capacity and increases fatigability. These observations imply that myostatin activation could promote a more oxidative and less fatigable muscle ...

Shoulder Rotation Test: A New Test for Discriminating Between Functional and Structural Weakness

Brain and Behavior, Volume 16, Issue 4, April 2026.
We introduce the shoulder rotation test, a simple bedside test combining the MRC scoring of shoulder internal rotation (IR) and external rotation (ER), for discriminating between functional weakness (FW) and structural weakness (SW) of the upper limbs.

CRISPR Activation Reveals the Spliceogenicity of an Intronic NEB Variant in Fetuses With Arthrogryposis Multiplex Congenita 6

Clinical Genetics, Volume 109, Issue 4, Page 772-777, April 2026.
CRISPR activation of NEB in fibroblasts, followed by RNA‐sequencing, documents spliceogenic effects of a NEB intronic variant. The assay enabled variant reclassification as likely pathogenic, providing molecular diagnosis in fetuses with Arthrogryposis multiplex congenita 6.

Nemaline Myopathy

Abstract This chapter presents a 58-year-old woman with progressive weakness, dysphagia, and dyspnea, ultimately diagnosed with sporadic late-onset nemaline myopathy. She has a complex history that includes antiphospholipid antibody syndrome, pulmonary hypertension, monoclonal gammopathy, positive antinuclear antibody (ANA), and ...

ACTA1‐Related Adult‐Onset Scapuloperoneal Myopathy With Cores and Rods

Neuropathology and Applied Neurobiology, Volume 52, Issue 2, April 2026.
We report a patient with an adult‐onset, slowly progressive, ACTA1‐related scapuloperoneal myopathy with cores and rods, determined by the heterozygous variant NM_001100.4:c.1001C > T, p.(Pro334Leu). The scapuloperoneal phenotype could represent a distinct subcategory, and the characterisation of this patient with a less severe, different clinical ...

Molecular classification of nemaline myopathies: “nontyping” specimens exhibit unique patterns of gene expression

Neurobiology of Disease, 2004
Nemaline myopathy (NM) is a slowly progressive or nonprogressive neuromuscular disorder caused by mutations in genes encoding skeletal muscle sarcomeric thin filament proteins. It is characterized by great heterogeneity at the clinical, histopathological,
