Myokines: Discovery Challenges and Therapeutic Impediments.

Physical activity has been linked with maintenance of bodily health and prevention of numerous pathologies which might arise in its absence. Physical surge renders the skeletal muscles of the body to come into action which then, besides per forming the basic functions of locomotion and maintenance of body posture, produce various proteinaceous secretions. These secretions contain skeletal muscle-released biochemical products known as myokines. More than 650 myokines have been identified and this list is increasing so rapidly that this branch of proteomics can now be designated as a 'myokinome'. This review was planned to describe the major challenges faced in myokine discovery, barriers in use of myokines as a treatment modality and the techniques utilised to overcome these scientific hurdles. Establishment of correlation of myokines with the state of health and disease can help improve clinical diagnostics and will ultimately improve the quality of life of patients.
