Consistently, according to the immunohistochemical result from THPA, the PTTG1 antibody was moderately stained in the urothelial carcinoma of the bladder and was lowly stained or not detected in normal or inflammatory bladder tissue (Antibody: HPA045034 and CAB008373) (Fig. 2), which confirmed the elevated protein expression levels of PTTG1 in BLCA. The gene discussed is PTTG1; the disease is bladder transitional cell carcinoma.
