Myofibrillar proteins exist as multiple isoforms that derive from multigene (isogene) families.
Additional isoforms, including products of tropomyosin, myosin light chain 1 fast, troponin T …

A unique characteristic of skeletal muscle is its diversity. This diversity is created by its
design, ie, its fiber composition and the heterogeneity of the individual fibers. Indeed, we …

1. This study was performed to assess whether muscle contractile properties are related to
the presence of specific myosin heavy chain (MHC) isoforms. 2. Force‐velocity relations and …

The purpose of this study was to compare the excitability and contractility of three-
dimensional skeletal muscle constructs, termed myooids, engineered from C2C12 myoblast …

Although it is generally believed that phosphorylation of the regulatory light chain of myosin
is required before smooth muscle can develop force, it is not known if the overall degree of …

Differences in the mechanical properties of mammalian smooth, skeletal, and cardiac
muscle have led to the proposal that the myosin isozymes expressed by these tissues may …

Skeletal muscle fibers are classified according to the myosin heavy chain (MHC) isoforms
and other myofibrillar proteins expressed within these cells. In addition to 'pure'fibers …

Contraction of vertebrate striated muscles results from cyclic interactions between the
proteins myosin and actin, which in intact muscles are formed into parallel arrays of …

Little is known about the structural response of the diaphragm to controlled mechanical
ventilation. We examined effects of this intervention on muscle mass, myosin heavy chain …
