From: Exon array analysis reveals neuroblastoma tumors have distinct alternative splicing patterns according to stage and MYCN amplification status

Figure 1

Principal component analysis (PCA) of 47 neuroblastoma samples by log2-transformed normalized intensity of core probesets. PCA was performed using NI values of core probesets (n = 221,809) across all samples after quality filtering. Stage 1- and 4+ samples are clearly separated from each other, while stage 4- samples are located between them. Blue, stage 1-; green, stage 4-; red, stage 4+ tumors.
