Correlation matrices analysis of TNFAIP1/POLDIP2 SFGM in 38 breast cancer cell lines (see materials and methods). Due to the small sample size (38 cell lines) Kendall-Tau correlation coefficients were calculated. Only significant correlation coefficients (α = 1%) are shown. A. Correlation matrix of the TNFAIP1/POLDIP2 SFGM produced by using original expression values (Additional file 3). B. Correlation matrix of the TNFAIP1/POLDIP2 SFGM produced by using expression values normalized by DNA copy number (Additional file 3).
