BACKGROUND Skeletal muscle atrophy is a serious concern for the rehabilitation of patients afflicted by prolonged limb restriction. This debilitating condition is associated with a marked activation of NFκB activity. The ubiquitin-proteasome pathway degrades the NFκB inhibitor IκBα, enabling NFκB to translocate to the nucleus and bind to the target genes(More)
Skeletal muscle ageing is characterized by faulty degenerative/regenerative processes that promote the decline of its mass, strength, and endurance. In this study, we used a transcriptional profiling method to better understand the molecular pathways and factors that contribute to these processes. To more appropriately contrast the differences in(More)
PURPOSE To determine the functional contribution of retinoic acid receptor (RAR)-alpha in the developing murine neural retina, through a phenotypic analysis of the corresponding null mutants. METHODS RARalpha mutant (Rara(-/-)) mice were compared with wild-type littermates at several stages of pre- and postnatal development. An RA-response element(More)
The stiffness of the myogenic stem cell microenvironment markedly influences the ability to regenerate tissue. We studied the effect of damaged myofibers on myogenic progenitor cell (MPC) proliferation and determined whether the structural integrity of the microenvironment contributes to phenotypic changes. Individual myofibers were isolated and cultured(More)
