CCNA2 and cancer: We further investigated the association of the levels of these ten genes with the corresponding mRNAsi in the cancer samples (Figure 8d–m) and showed that CCNA2 (r = 0.608, P < 0.001, Figure 8g) and PTGIS (r = −0.347, P < 0.001, Figure 8i) were significantly and linearly correlated with mRNAsi.
