In addition to their possible role in correlations between RF-EMR and glioblastoma, the major function of oligodendrocytes in the brain is to produce myelin, and our finding that 2.4 GHz EMR exposure altered the expression of C/EBPβ and its interacting proteins in OLN-93 leads us to speculate that there may be a correlation between RF-EMR and myelination. The gene discussed is CEBPB; the disease is glioblastoma.
