Recent evidence points to a strong relationship between increased mitochondrial biogenesis and increased survival in eukaryotes. Branched-chain amino acids (BCAAs) have been shown to extend chronological life span in yeast. However, the role of these amino acids in mitochondrial biogenesis and longevity in mammals is unknown. Here, we show that a BCAA-enriched mixture (BCAAem) increased the average...
Myogenesis is driven by an extraordinary array of cellular signals that follow a common expression pattern among different animal phyla. Myostatin (mstn) is a secreted growth factor that plays a pivotal role in skeletal muscle mass regulation. The aim of the present study was to investigate mstn expression in a large mammal (the pig) in order to ascertain whether distinct expression changes of this...
Sarcomeric myosin heavy chains (MyHC) are the major contractile proteins of cardiac and skeletal muscles and belong to class II MyHC. In this study the sequences of nine sarcomeric MyHC isoforms were obtained by combining assembled contigs of the dog genome draft available in the NCBI database. With this information available the dog becomes the second species, after human, for which the sequences...
