In addition to their impact on adult muscle fiber phenotypes, TH plays an important role during muscle development and maturation.
A low-volume, high-intensity approach, such as sprint interval training, may favor an anabolic environment (e.g., growth hormone, insulin-like growth factor-I, IGF binding protein-3, and testosterone) [88-92] [88-92]in a maintainiber phenotype associated with strength and power capabilities [93], and increase endurance and neuromusclear-related outcomes [94-96].
This corroborates the notion that the mutant muscle fiber phenotype arises independently and is subsequent to normal somite establishment, providing an opportunity to decouple roles of Wnt/β-catenin in myofibrillogenesis versus somite patterning.
Below each panel, statistics of muscle fiber phenotype observed are reported.
Below each panel, statistics of muscle fiber phenotype observed are reported as normal (6 7 mf), mild (4 5 mf), or strong (0 2 mf).
On the other hand, when NMES was applied with a lower electrical frequency (~20 Hz) and long activation times, it led to higher oxidative properties and a fast-to-slow conversion of the muscle fiber phenotype [ 20].
Our data reveal that p43, a mitochondrial T3 receptor can influence the acquisition of muscle fibers phenotype.
The influence of p43 on mitochondrial activity and biogenesis [9], [11], and the fact that mitochondrial metabolism is deeply involved in the metabolic muscle-fiber phenotype led us to examine the potential role of p43 in the control of muscle fiber characreristics.

We further demonstrate that an FTI can efficiently inhibit the farnesylation of zebrafish progerin (zebrafish lamin A-Δ37/zProgerin) and suppress the abnormal nuclear morphologies, muscle fiber defects and embryonic senescence phenotypes.
