Overexpression of c-Jun in mouse Schwann cells of uninjured nerves


ABSTRACT: Two mouse lines, OE/+ and OE/OE were generated expressing graded elevation (6 fold and 28 fold, respectively) of c-Jun protein selectively in Schwann cells. The effects of this on global gene expression and cellular structure in uninjured nerves was analysed during development and in the adult. Changes in gene expression and cellular arrangements were mild but detectable in c-Jun OE/+ mice, while nerves in c-Jun OE/OE mice showed obvious de-myelination and gene expression changes, including up- and down-regulation of genes previously shown to be controlled by c-Jun in Schwann cells.

Schwann cell c-Jun is implicated in adaptive and maladaptive functions in peripheral nerves. In injured nerves, this transcription factor promotes the repair Schwann cell phenotype and regeneration and promotes Schwann-cell-mediated neurotrophic support in models of peripheral neuropathies. However, c-Jun is associated with tumor formation in some systems, potentially suppresses myelin genes, and has been implicated in demyelinating neuropathies. To clarify these issues and to determine how c-Ju  ...[more]
