Fig. 1: Principal component analysis (PCA) of global DNA methylation.
From: DNA methylation and copy number variation profiling of T-cell lymphoblastic leukemia and lymphoma

PCA scoring plots based on the average β values of 397 316 CpGs. The samples in the PCA plots are colored by (a) sample type: T-ALL (n = 77), T-LBL (n = 15), and non-malignant lymph node (n = 5) and bone marrow (N = 11) reference tissue, (b) Age group: pediatric (n = 73) and adult (n = 19) and (c) CIMP status (59 CIMP+ and 33 CIMP−).
