FDPS and bladder transitional cell carcinoma: Furthermore, by analyzing the tissue microarray (containing 68 BLCA specimens and 40 paracancerous tissues) (Fig. 2e–g), we found that FDPS protein levels were upregulated in BLCA tissues compared to paracancerous tissues (Fig. 2f), and patients with higher FDPS protein levels had poorer overall survival (Fig. 2g).
