Proteolytic Gene Expression Differs At Rest and After Resistance Exercise Between Young and Old Women

1 Dec 2007

Abstract excerpt

BACKGROUND: Skeletal muscle atrophy in rodents is associated with increased gene expression of proteolytic markers muscle-RING-finger protein 1 (MuRF-1) and atrogin-1. In humans with age-related muscle atrophy, known as sarcopenia, little is known about these key proteolytic biomarkers. Therefore, the purpose of this investigation was 2-fold: (i) measure messenger RNA (mRNA) expression of proteolytic genes...
