MBP and oligodendroglioma: In our regression analysis, the genes that were among the most highly correlated with the degree of oligodendroglioma component percentage (OC%) were also oligodendrocyte specific, including MBP, MOBP, PDGFRA, HOXD1, a transcription factor expressed by oligodendrocytes that binds to the human myelin oligodendrocyte glycoprotein promoter, and PLP1, a gene specific to myelinating cells like oligodendrocytes.
