The role of genes and myokines of developing sarcopenia: A review

Abstract

Sarcopenia is associated with progressive generalized skeletal muscle weakness, persistent decline in muscle strength, function, and quality of life in the elderly population. The presence of sarcopenia worsens the prognosis of older patients. In this regard, the study of the etiology and pathogenesis of sarcopenia, the identification of early markers for the diagnosis of this disease are relevant areas today. Myokines are secreted by skeletal muscle and play a important role in the regulation of muscle mass and function, metabolic homeostasis. Myokine synthesis disruption may contribute to the development of sarcopenia. In addition, we can see the polymorphism association of various genes with the development of the disease. This review brings together current knowledge about myokines and genetic factors as potential biomarkers for the early diagnosis of sarcopenia.
