In Oncomine database, only TPX2 (P=0.171) showed a statistically insignificant difference when comparing the gene expression between BC sample and normal bladder tissue samples while CDK1 (P=0.015), UBE2C (P=9.29E-7), CDC20 (P=2.07E-8) and CDCA8 (P=1.22E-13) were validated as significant (Figure 7). This evidence concerns the gene UBE2C and breast cancer.
