Figure 5. O-6-methylguanine-DNA methyltransferase (MGMT) copy number segments (log2 tumor/normal) plotted against SGK1 copy number segments (log2 tumor/normal). SGK1 copy number segments correlate significantly overall with MGMT copy number segments (r=0.139, p=0.001). The data appear to define two distinct groups: one in which MGMT values close to zero do not relate to SGK1; and a second group in which SGK1 and MGMT are linearly correlated.
