Myostatin is a negative regulator of skeletal muscle growth and in fact acts as a potent inducer of "cachectic-like" muscle wasting in mice. The mechanism of action of myostatin in promoting muscle wasting has been predominantly studied in murine models. Despite numerous reports linking elevated levels of myostatin to human skeletal muscle wasting conditions, little is currently known about the...
BACKGROUND Myostatin inhibition is a promising therapeutic strategy to maintain muscle mass in a variety of disorders, including the muscular dystrophies, cachexia, and sarcopenia. Previously described approaches to blocking myostatin signaling include injection delivery of inhibitory propeptide domain or neutralizing antibodies. METHODOLOGY/PRINCIPAL FINDINGS Here we describe a unique method...
Myostatin, a member of the TGF-beta family, has been identified as a powerful inhibitor of muscle growth. Absence or blockade of myostatin induces massive skeletal muscle hypertrophy that is widely attributed to proliferation of the population of muscle fiber-associated satellite cells that have been identified as the principle source of new muscle tissue during growth and regeneration. Postnat...
A human therapeutic that specifically modulates skeletal muscle growth would potentially provide a benefit for a variety of conditions including sarcopenia, cachexia, and muscular dystrophy. Myostatin, a member of the TGF-beta family of growth factors, is a known negative regulator of muscle mass, as mice lacking the myostatin gene have increased muscle mass. Thus, an inhibitor of myostatin may...
Animal studies in vivo indicate that leptin treatment in extremely leptin-sensitive ob/ob mice reduces body weight exclusively by reducing fat mass and that it increases muscle mass by downregulating myostatin expression. Data from human trials are limited. Therefore, we aimed at characterizing the effects of leptin administration on fat mass, lean body mass, and circulating regulators of muscl...
Myostatin is an important negative regulator of muscle growth. Natural mutations and knockouts in animals produce a “double-muscled” phenotype the basis of which is a dramatic increase in muscle mass. Therapeutics that target myostatin are currently in development. There are almost no documented side effects of suppression, and early research suggests that myostatin inhibition can restore funct...
BACKGROUND Cardiac cachexia is characterized by an exaggerated loss of skeletal muscle, weakness, and exercise intolerance, although the cause of these effects remains unknown. Here, we hypothesized that the heart functions as an endocrine organ in promoting systemic cachexia by secreting peptide factors such as myostatin. Myostatin is a cytokine of the transforming growth factor-beta superfami...
Abstract Myostatin is a negative regulator of muscle mass and its inhibition represents promising strategy for the treatment disorders type 2 diabetes. However, there currently no clinically effective myostatin inhibitor, therefore novel methods are required. We evaluated use antisense phosphorodiamidate morpholino oligomers (PMO) to reduce expression in skeletal measured their effects on gluco...
Background and Objectives: Muscular atrophy is one of the indicators of uncontrolled diabetes. The aim of the current study was to investigate effects of eight weeks of resistance training (RT) on myostatin gene expression in soleus muscles and insulin resistance in streptozotocin (STZ)-induced diabetic rats. Materials and Methods: In general, 14 Wistar male rats weighing 200–250 g and aging 8...
