p62 and Nrf2 are essential for exercise-mediated enhancement of antioxidant protein in muscle
Regular exercise prevents oxidative stress-induced muscle wasting, at least partially by improving the antioxidant defense system. In the present study, we found that regular endurance exercise enhances the expression of p62/SQSTM1 (p62) and its phosphorylation at Ser 351 thereby dissociating nuclear factor erythroid 2-related factor 2 (Nrf2) from Keap1, which results in increased Nrf2 nuclear translocation and DNA binding activity. These findings suggest that Ser 351 phosphorylation of p62 plays a critical role in this regulation. (2019-04-25)

Researchers characterize important regulators of tissue inflammation, fibrosis and regeneration
Although macrophages (cells involved in the detection and destruction of bacteria and other harmful organisms as well as dead cells) are classified as immune cells functioning in the activation and resolution of tissue inflammation, it is now clear that they are critically involved in a variety of disease processes, such as chronic inflammatory diseases, tumor growth and metastasis and tissue fibrosis. (2020-08-10)

New method to grow and transplant muscle stem cells holds promise for treatment of MD
Satellite cells are stem cells found in skeletal muscles. While transplantation of such muscle stem cells can be a potent therapy for degenerative muscle diseases such as Duchenne muscular dystrophy, these cells tend to lose their transplantation efficiency when cultured in vitro. In a study in the current issue of the Journal of Neuromuscular Diseases, researchers treated these stem cells with leukemia inhibitory factor, which effectively maintained the undifferentiated state of the satellite cells and enhanced their transplantation efficiency. (2016-06-28)

Stem cells get a workout
Muscular dystrophies are characterized by severe muscle damage, ultimately through the loss of the ability to regenerate muscle. In the July 15 issue of the Journal of Clinical Investigation, researchers from the University of Milan present a technique that reduced muscle damage, alleviated the muscular dystrophy symptoms, and restored the cellular pool required for muscle regeneration in a mouse muscular dystrophy model. This study provides new leads in the treatment of these debilitating muscle diseases. (2004-07-15)

Treatment stimulates growth and regeneration of injured adult skeletal muscle
Scientists have discovered that a group of chemicals known as Histone Deacetylase (HDAC) inhibitors stimulate growth and regeneration of adult skeletal muscle cells by increasing expression of the protein follistatin. The research may provide new avenues for developing effective means to promote regeneration in muscular dystrophies. The functional link between HDAC inhibitors, follistatin, and adult muscle regeneration is especially provocative as an HDAC inhibitor is already being used clinically in humans as an anti-cancer therapeutic. (2004-05-10)

Cell transplants may improve severe urinary incontinence
Severe urinary incontinence can be caused by urethral sphincter muscle deficiency, often associated with trauma during childbirth, prostate surgery, or aging. When skeletal myoblasts -- progenitor muscle cells with the potential to develop into muscle fiber -- were transplanted into female rats suffering from urethral sphincter deficiency, transplanted muscle cells helped increase urethral pressure, improving incontinence. Implanting myoblasts could be a potential innovative therapy for urethral deficiencies that lead to human incontinence. (2007-11-13)

One or the other: Why strength training might come at the expense of endurance muscles
The neurotransmitter brain-derived neurotrophic factor (BDNF) acts in the muscle, so that during strength training endurance muscle fiber number is decreased. Researchers at the University of Basel's Biozentrum have more closely investigated this factor, from the group of myokines, and demonstrated that it is produced by the muscle and acts on both muscles and synapses. The results published in PNAS also provide new insights into age-related muscle atrophy. (2019-07-25)

How work tells muscles to grow
We take it for granted, but the fact that our muscles grow when we work them makes them rather unique. Now, researchers have identified a key ingredient needed for that bulking up to take place. A factor produced in working muscle fibers apparently tells surrounding muscle stem cell (2012-01-03)

Stem cells may be the key to staying strong in old age

0.6% soy isoflavone in the diet decrease muscle atrophy
Scientists at Tokyo Institute of Technology (Tokyo Tech) have discovered a means of reducing muscle atrophy by the addition of the soy-derived isoflavone aglycone (AglyMax) to the diet of mice. This attenuation by soy isoflavone is attributable to block the apoptosis-dependent pathway in muscle fiber. The AglyMax supplement also anticipate to attenuate age-related muscle loss, sarcopenia. (2018-01-18)

Basis of development of vertebrate limb muscles has been established in cartilaginous fishes
Scientists at Tokyo Institute of Technology (Tokyo Tech) have discovered that both bony and cartilaginous fish develop their appendages via a shared mechanism -- the mechanism is also observed in land-dwelling vertebrates such as mice. They found the fin muscles of cartilaginous are formed by muscle precursors expressing Lbx1 expression, a gene that coordinates limb-muscle formation. This work revisits some related evolutionary hypotheses using a molecular biology approach and provides new insights. (2017-10-02)
