Figure 3From: Altered PPP2R2A and Cyclin D1 expression defines a subgroup of aggressive luminal-like breast cancerExpression levels of PPP2R2A according to CNA. Using data from the TCGA database, the expression levels of PPP2R2A were plotted according to the following classifications of gene copy number: normal (n = 278), heterozygous deletion (HetDel) (n = 411) or homozygous deletion (HomDel) (n = 47). Significant differential expression was observed for all pair-wise comparisons using Student’st-test (p-value <0.001 for all comparisons), showing a positive relationship between copy number and gene expression.Back to article page
