Specification of vertebrate slow-twitch muscle fiber fate by the transcriptional regulator Blimp1

Developmental Biology, 2008
Skeletal muscles of vertebrates are typically composed of slow- and fast-twitch fibers that differ in their morphology, gene expression profiles, contraction speeds, metabolic properties and patterns of innervation. During myogenesis, how muscle precursors are induced to mature into distinct slow- or fast-twitch fiber-types is inadequately understood ...

Lycopene increases the proportion of slow-twitch muscle fiber by AMPK signaling to improve muscle anti-fatigue ability

Journal of Nutritional Biochemistry, 2021
Lycopene has a wide range of biological functions, especially its antioxidant capacity. However, effects of lycopene on muscle fatigue resistant and muscle fiber type conversion are unknown. In this study, we found that lycopene significantly prolonged the swimming time to exhaustion in mice.

Regional distribution of slow‐twitch muscle fibers after reinnervation in adult rat hindlimb muscles

Muscle & Nerve, 2002
AbstractIn adult rats, the sciatic nerve was unilaterally sectioned and reunited above the knee. Following a survival time of 21 weeks, five muscles were removed from both lower hindlimbs after determining their intra‐limb positions. In each muscle, cryostat sections from seven equidistant proximo‐distal levels were stained for myofibrillar ATPase ...

Contraction of glycerinated rabbit slow-twitch muscle fibers as a function of MgATP concentration

American Journal of Physiology-Cell Physiology, 1992
We have measured the isometric tension and force-velocity relationships of glycerinated rabbit slow-twitch semimembranosus muscle as a function of MgATP concentration ([MgATP]) and have compared the results with those obtained previously from fast-twitch psoas muscle. We find that isometric tension decreases as [MgATP] increases.

Fine structure of fast‐twitch and slow‐twitch guinea pig muscle fibers

Journal of Morphology, 1973
AbstractThe guinea pig soleus muscle is a convenient model for the study of slow‐twitch intermediate (STI) fiber ultrastructure because it is composed entirely of fibers of this class. Such fibers were compared with fast‐twitch red (FTR) and fast‐twitch white (FTW) fibers from the vastus lateralis muscle.FTW fibers are characterized by small, sparse ...

Ca2+ release from sarcoplasmic reticulum of skinned fast- and slow-twitch muscle fibers

American Journal of Physiology-Cell Physiology, 1988
We have performed a comparative study of Ca2+ release from the sarcoplasmic reticulum (SR) of chemically skinned fibers from rabbit fast- and slow-twitch skeletal muscle. Ca2+ fluxes have been indirectly monitored by following either tension development or the inhibition of net Ca2+-loading rate by a light-scattering method.
