Abstract:
Previous evidence showed mutations of the neurofibromin type 2 gene (Nf2), encoding the tumor suppressor protein merlin, in sporadic and vestibular schwannomas affecting Schwann cells (SC). Accordingly, efforts have been addressed to identify possible factors, even environmental, that may regulate neurofibromas growth. In this context, we investigated the exposure of SC to an electromagnetic field (EMF), which is an environmental issue modulating biological processes. Here we show that SC exposed to 50 Hz EMFs change their morphology, proliferation, migration and myelinating capability. In these cells merlin is downregulated, leading to activation of two intracellular signaling pathways, ERK/AKT and Hippo. Interestingly, SC change their phenotype toward a proliferative/migrating state, which in principle may be pathologically relevant for schwannoma development.
