This invention belongs to the field of
biomedical technology, specifically involving the application of the MRPL41
gene /
protein in the preparation of drugs for treating age-related
sarcopenia. This invention is the first to demonstrate that MRPL41 is a key rate-
limiting factor in the
assembly of mitochondrial ribosomes in aging
muscle satellite cells, establishing it as a core target for the treatment of age-related
sarcopenia. Overexpression of MRPL41 can promote the
assembly of mitochondrial 55S
holoenzymes, improve the translation efficiency of mitochondrial-encoded proteins, repair mitochondrial dysfunction at its source, thereby promoting
muscle repair, improving
muscle atrophy, and achieving the treatment of age-related
sarcopenia. This invention provides a precise microscopic target for the treatment of age-related sarcopenia, overcoming the limitations of existing clinical therapies (such as
hormone replacement and simple
nutritional supplementation) due to significant side effects and "
anabolism resistance," providing a new direction for the development of innovative drugs specifically for the treatment of age-related sarcopenia, and has excellent application prospects.
