In other tumors we tested (bladder urothelial carcinoma, glioblastoma and head and neck squamous cell carcinoma), there was a strong and statistically significant positive correlation between the mRNA expression of Fubp1 and both Ccna genes, raising a possibility that this Fubp1-cyclin A axis may be ubiquitous (Supplementary Figure S3). This evidence concerns the gene FUBP1 and bladder transitional cell carcinoma.
