Project description:Muscle-specific populations of proprioceptive sensory neurons form selective connections with spinal motor neurons, implying the existence of molecular distinctions between proprioceptor subpopulations. Here, we compare the gene expression profiles of proprioceptors that supply an antagonistic muscle pair functioning at a single hindlimb joint.

Project description:We generated transgenic mice expressing constitutively SOCS-3 specifically in skeletal muscle. SOCS proteins are implicated in the negative regulation of various pathways including insulin signaling pathway. Our transgenic mice are predisposed to obesity and systemic insulin resistance compared to control mice. We used microarrays to detail the variations of gene expression in muscle from transgenic mice versus controls. Keywords: transgenic, tibialis anterior, SOCS-3
