Satellite cells (SCs) are myogenic stem cells required for regeneration of adult skeletal muscles. A proper balance among quiescence, activation and differentiation is essential for long-term maintenance of SCs and their regenerative function. Here we show a function of Pten (phosphatase and tensin homologue) in quiescent SCs. Deletion of Pten in quiescent(More)
Brown adipose tissue (BAT) represents a promising agent to ameliorate obesity and other metabolic disorders. However, the abundance of BAT decreases with age and BAT paucity is a common feature of obese subjects. As brown adipocytes and myoblasts share a common Myf5 lineage origin, elucidating the molecular mechanisms underlying the fate choices of brown(More)
Myogenic regulatory factors (MRFs), including Myf5, MyoD (Myod1) and Myog, are muscle-specific transcription factors that orchestrate myogenesis. Although MRFs are essential for myogenic commitment and differentiation, timely repression of their activity is necessary for the self-renewal and maintenance of muscle stem cells (satellite cells). Here, we(More)
Heat therapy has been shown to promote capillary growth in skeletal muscle and in the heart in several animal models, but the effects of this therapy on angiogenic signaling in humans are unknown. We evaluated the acute effect of lower body heating (LBH) and unilateral thigh heating (TH) on the expression of angiogenic regulators and heat shock proteins(More)
Exercise promotes multiple beneficial effects on muscle function, including induction of mitochondrial biogenesis. miR-133a is a muscle-enriched microRNA that regulates muscle development and function. The role of miR-133a in exercise tolerance has not been fully elucidated. In the current study, mice that were deficient in miR-133a demonstrated low maximal(More)
Indirect calorimeter is a powerful tool to monitor resting energy metabolism through the measurement of oxygen (O2) consumption and carbon dioxide (CO2) production. From the measurement of VO2 and VCO2, the respiratory exchange ratio (RER) can be calculated to assess energy fuel utilization and energy expenditure (Evan et al., 2012). Previously, indirect(More)
