Furthermore, we also found a statistically significant positive correlation between FOXM1 protein expression levels and UBE2C gene expression in some selected tumors: 77 ESCC (r = 0.32, p = 0.004), 48 esophageal adenocarcinomas (r = 0.37, p = 0.008), 887 breast cancer samples (r = 0.58, p < 0.0001), 340 bladder urothelial carcinomas (r = 0.36, p < 0.0001), 360 lung adenocarcinomas (r = 0.36, p < 0.0001), and 336 stomach adenocarcinomas (r = 0.34, p < 0.0001) (Figure 2A–F), suggesting a potential regulation of UBE2C by the transcriptional factor FOXM1. This evidence concerns the gene FOXM1 and esophageal squamous cell carcinoma.
