The loss in muscle mass coupled with a decrease in specific force and shift in fiber composition are hallmarks of aging. Training and regular exercise attenuate the signs of sarcopenia. However, pathologic conditions limit the ability to perform physical exercise. We addressed whether electrical stimulation (ES) is an alternative intervention to improve(More)
Calcium release units (CRUs) and mitochondria control myoplasmic [Ca2+] levels and ATP production in muscle, respectively. We recently reported that these two organelles are structurally connected by tethers, which promote proximity and proper Ca2+ signaling.Here we show that disposition, ultrastructure, and density of CRUs and mitochondria and their(More)
Dear Editor, Nucleophosmin (NPM1) is a nucleolar protein implicated in ribogenesis, centrosome duplication and stress response. 1 NPM1 is mutated in ~ 30% of acute myeloid leukemia (AML) patients. 2 Heterozygous mutations involve few base duplications or insertions in the gene's last exon. In all cases, the reading frame is altered and mutated NPM1 (NPM1c+)(More)
Age-related sarcopenia is characterized by a progressive loss of muscle mass with decline in specific force, having dramatic consequences on mobility and quality of life in seniors. The etiology of sarcopenia is multifactorial and underlying mechanisms are currently not fully elucidated. Physical exercise is known to have beneficial effects on muscle(More)
