AR and central nervous system cancer: Comparative analysis of DNA methylation in gliomas with high vs. low immunohistochemical expression of the AR involved four different regions of the AR gene body: AR CAG repeats (promoter) from coordinates 67,545,204 to 67,545,299; the AR region within CAG and CGG repeats (intra CAG-CGG) from 67,545,904 to 67,546,136; the AR region before CGG repeat from 67,546,381 to 67,546,405; and, finally, the AR region within the CGG repeats from 67,546,492 to 67,546,664.
