Putative MicroRNA-mRNA Networks Upon Mdfi Overexpression in C2C12 Cell Differentiation and Muscle Fiber Type Transformation [PDF]
Mdfi, an inhibitor of myogenic regulatory factors, is involved in myoblast myogenic development and muscle fiber type transformation. However, the regulatory network of Mdfi regulating myoblasts has not been revealed.

Phosphoproteomic analysis identifies differentially expressed phosphorylation sites that affect muscle fiber type in pigs [PDF]
Skeletal muscle of livestock is composed of both fast- and slow-twitch muscle fibers, which are key factors in their meat quality. However, the role of protein phosphorylation in muscle fiber type is not completely understood. Here, a fast-twitch (biceps

Optimizing the methodology for precise estimation of skeletal muscle fiber type proportions in humans [PDF]
Isolating individual muscle fibers and characterizing their myosin heavy chain (MHC) content using SDS-PAGE has become an increasingly common method for describing skeletal muscle fiber type proportions.

Background: Ageing of skeletal muscle is characterized in some by muscle fiber type grouping due to denervation-reinnervation cycles, but the severity of fiber type grouping varies widely across individuals of the same chronological age.

Targeted myostatin loss-of-function mutation increases type II muscle fibers in Meishan pigs
Myostatin (MSTN) is a negative regulator of skeletal muscle growth and development. The skeletal muscle in MSTN−/– mice is significantly hypertrophied, with muscle fiber type II increasing significantly while muscle fiber type I decreasing.

Nuclear receptors and skeletal muscle fiber type
The contractile and metabolic properties of skeletal muscle depend on muscle fiber type composition. There are two major fiber types: type 1 fibers (slow-twitch oxidative) and type 2 fibers (fast-twitch glycolytic).

Architecture and fiber type of the pyramidalis muscle [PDF]
The paired pyramidalis muscles are small triangular-shaped muscles that lie between the anterior surface of the rectus abdominus and the posterior surface of the rectus sheath. The precise function of pyramidalis muscles is unclear, but together the muscles are thought to tense the linea alba. The muscles are not always present, or are often unilateral,

Protein profile of fiber types in human skeletal muscle: a single-fiber proteomics study
Background Human skeletal muscle is composed of three major fiber types, referred to as type 1, 2A, and 2X fibers. This heterogeneous cellular composition complicates the interpretation of studies based on whole skeletal muscle lysate.
