Clathrin’s muscle-building regimen
C lathrin is best known for its role in endocytosis and other membrane traffi cking events, but the protein's heavy chain has several additional functions , including organization of mitotic spindles and coordination of actin fi laments at intercellular adhesions. Vassilopoulos et al. now reveal that the clathrin heavy chain (CHC) also helps to organize skeletal muscle sarcomeres by promoting t...
متن کاملBuilding muscle: molecular regulation of myogenesis.
The genesis of skeletal muscle during embryonic development and postnatal life serves as a paradigm for stem and progenitor cell maintenance, lineage specification, and terminal differentiation. An elaborate interplay of extrinsic and intrinsic regulatory mechanisms controls myogenesis at all stages of development. Many aspects of adult myogenesis resemble or reiterate embryonic morphogenetic e...
متن کاملBuilding a robotic link between muscle dynamics and hydrodynamics.
This study used a novel feedback approach to control a robotic foot using force and length signals transmitted from an isolated Xenopus laevis frog muscle. The foot's environment (inertial versus hydrodynamic), gearing (outlever/inlever) and size were changed to alter the muscle's load. Upon nerve stimulation (250 Hz, 80 ms train duration), variation in loading generated a range of muscle stres...
متن کاملVascular smooth muscle progenitor cells: building and repairing blood vessels.
Molecular pathways that control the specification, migration, and number of available smooth muscle progenitor cells play key roles in determining blood vessel size and structure, capacity for tissue repair, and progression of age-related disorders. Defects in these pathways produce malformations of developing blood vessels, depletion of smooth muscle progenitor cell pools for vessel wall maint...
متن کاملMuscle-building therapy in treatment of nasal valve collapse.
OBJECTIVES The purpose of this paper is to describe the outcome of muscle-building therapy for nasal muscles in cases of nasal valve stenosis or collapse. The present study was performed to investigate the best way to combine transcutaneous and intranasal surface electromyography (sEMG) biofeedback training of muscles involved in nasal valve function with a home exercise program and electric st...
