Positive correlation between PTTG3P and FoxM1 were also observed in liver cancer (R = 0.593, P = 0.000), colorectal cancer (R = 0.341, P = 0.000) and gastric cancer (R = 0.900, P = 0.000) tissues by analyzing TCGA and GEO databases (Supplementary Fig. 1c). This evidence concerns the gene PTTG3P and gastric cancer.
