Force enhancement during lengthening of an active muscle, a condition that normally occurs
during locomotion in vivo, is attributed to recruitment of myosin heads that exhibit fast …

Myostatin is a negative regulator of muscle growth, and absence of the functional myostatin
protein leads to the heavy muscle phenotype in both mouse and cattle. Although the role of …

Some rodent species show rhythmic bouts of vibrissal protractions and retractions, referred
to as whisking, that are among the fastest movements performed by mammals. To better …

The objective of this study was to investigate the cellular localisation of MyoD and myogenin
in human skeletal muscle fibres as well as the possible alterations in the expression of …

Limited information exists about the putative role and expression in human skeletal muscle
cells of the 88-kDa integral membrane protein fatty acid translocase (FAT), highly …

Myogenesis is regulated by the MyoD class of myogenic regulatory factors (MRFs). These
basic helix-loop-helix transcription factors dimerize with E proteins to bind conserved E-box …

Abstract Background Secreted Hedgehog (Hh) signalling molecules have profound
influences on many developing and regenerating tissues. Yet in most vertebrate tissues it is …

The llama (Lama glama) is one of the few mammals of relatively large body size in which
three fast myosin heavy chain isoforms (ie, IIA, IIX, IIB) are extensively expressed in their …

Background: Despite a similar density of nicotinic acetylcholine receptors, the upper
esophageal sphincter is sensitive to partial neuromuscular block, whereas the pharyngeal …

Methods: Adult human EOMs were studied with SDS-PAGE, immunoblots and
immunocytochemistry, the latter with antibodies against six MyHC, 2 SERCA, 2 MyBP-C and …
