Figure 1.
Copy number plots along chromosome 9p for four TCGA primary tumors (reported to have homozygous deletion of CDKN2A/B), two xenografts, two cell lines, and normal human astrocytes (NHAs). Each of the depicted xenografts and cell lines have homozygous deletion of the CDKN2A/B locus with copy number <0.2, whereas the four TCGA primary tumors have hemizygous/heterogeneous deletion with copy numbers of 1.07, 1.32, 1.22, and 1.29 for TCGA-06-0122, TCGA-06-0133, TCGA-06-0143, and TCGA-06-0169 respectively.
