Abstract
Sarcopenia, commonly found in the elderly, causes a decrease in muscle mass and function. Lactobacillus curvatus HY7602-fermented antler (FA) is a functional food that increases muscle strength and ameliorates dexamethasone-induced muscle atrophy. In the present study, we evaluated the effects of FA on age-related muscle atrophy and its mechanism of action using 100-week-old BALB/c mice. Physiological changes during fermentation were investigated. The results showed that the oral administration of FA substantially recovered muscle loss up to 23.6% and improved physical performance, such as treadmill running distance and limb grip strength, in aged mice. A gene expression analysis of muscle fibers showed that the effect of FA on age-related muscle atrophy was significantly associated with the inhibition of protein degradation and apoptosis, muscle fiber regeneration, and increased mitochondrial biogenesis. In addition, the acetate and butyrate contents increased by more than 50% during the fermentation of antler. In conclusion, FA can be considered as a functional food ingredient capable of effectively controlling muscle atrophy caused by aging and can be a novel alternative treatment for sarcopenia.

An easy way to objectively quantify the muscular strength of mice and rats, and to assess the effect of drugs, toxins, muscular (i.e. myopathy) and neurodegenerative diseases on muscular degeneration. It is widely used in conjunction with the ROTAROD motor coordination test: a normally coordinated rodent will show a decreased latency to fall off the rotating rod if its muscular strength is low. The Grip Strength Test is a must for your research on activity, motor control & coordination, and is particularly well suited for studies on Parkinson's & Huntington's disease.
