abstract = {Sarcopenia of old age is characterized by the progressive
loss of skeletal muscle mass and concomitant decrease in
contractile strength. Age-related skeletal muscle
dysfunctions play a key pathophysiological role in the
frailty syndrome and can result in a drastically diminished
quality of life in the elderly. Here we have used mass
spectrometric analysis of the mouse hindlimb musculature to
establish the muscle protein constellation at advanced age
of a widely used sarcopenic animal model. Proteomic results
were further analyzed by systems bioinformatics of voluntary
muscles. In this report, the proteomic survey of aged
muscles has focused on the expression patterns of proteins
involved in the contraction-relaxation cycle, membrane
cytoskeletal maintenance and the formation of the
extracellular matrix. This includes proteomic markers of the
fast versus slow phenotypes of myosin-containing thick
filaments and actin-containing thin filaments, as well as
proteins that are associated with the non-sarcomeric
cytoskeleton and various matrisomal layers. The
bioanalytical usefulness of the newly established reference
map was demonstrated by the comparative screening of normal
versus dystrophic muscles of old age, and findings were
verified by immunoblot analysis.},
