The hypothesis was tested that mechanical loading, induced by hindlimb suspension and subsequent reloading, affects expression of the basement membrane components tenascin-C and fibronectin in the belly portion of rat soleus muscle. One day of reloading, but not the previous 14 days of hindlimb suspension, led to ectopic accumulation of tenascin-C and an increase of fibronectin in the endomysium of a proportion (8 and 15%) of muscle fibers. Large increases of tenascin-C (40-fold) and…

The findings emphasize the role of FAK‐regulated costamere turnover in the load‐dependent addition and removal of myofibrils, and argue for two phases of muscle remodeling with resistance training, which do not manifest at the macroscopic level.

The results suggest that mechanical loading directly and reciprocally controls the expression of extracellular matrix proteins of the tenascin family in skeletal muscle.

- BiologyJournal of neurocytology

The results show that tenascin expression in adult muscles is induced by both axon and muscle fibre damage but not by muscle inactivity, and NCAM, in accordance with previous observations, showed enhanced expression both as a result of inactivity and in association with tissue repair.
Differential response of macrophage subpopulations to soleus muscle reloading after rat hindlimb suspension.

Findings indicate that macrophage subpopulations are associated with distinct stages during the recovery process from hindlimb suspension: ED1+ macrophages areassociated with muscle necrosis, whereas ED2+ cells are associatedWith muscle regeneration.
Sarcomere lesion damage occurs mainly in slow fibers of reloaded rat adductor longus muscles.

Because active myofiber contractions are requisite for lesion formation, selective recruitment of slow fibers most likely explains their damage susceptibility and atrophy did not explain differential lesion damage across fiber types.
Mechanical loading regulates expression of talin and its mRNA, which are concentrated at myotendinous junctions.

Investigation of talin expression in developing and adult muscle and in situ RT-PCR showed that talin and its mRNA are concentrated and colocalized at myotendinous junctions, which indicates that increased mechanical loading promotes talin synthesis, which occurs principally at myotin junctions.

Changes recognised when regeneration was essentially 'complete' are reminiscent of changes that occur in muscles following compensatory hypertrophy produced by synergist ablation, and suggest that the EDL muscle is being made to do more active work and is being influenced by passive forces imposed on it.

Tenascin-C expression by fibroblasts is elevated in stressed collagen gels
- Biology, EngineeringThe Journal of cell biology

It is proposed that the tenascin-C promoter is directly or indirectly activated in fibroblasts generating and experiencing mechanical stress within a restrained collagen matrix, which may be an important aspect of the regulation of tenascIn-C expression during embryogenesis as well as during wound healing and other regenerative and morphogenetic processes.
