Changes in uroplakin secretion in the urothelium leads a gradual ability lost in neoplastic conditions. Urothelium is
one of the target regions where nitric oxide can damage. Therefore, in this study, the presence of iNOS and UPIII were investigated in
bovine enzootic hematuria cases. The results were supported by comparing them with those achieved by critical markers for malignancy
of tumor such as caspase 3, Bax, p53, PCNA, and VEGF. The presence of 8-OHDG, a good marker for oxidative DNA damage, was
also investigated. For this purpose, urinary bladders with enzootic hematuria were collected from the slaughterhouses. In
histopathological examinations, neoplastic, pre-neoplastic, and inflammatory lesions were observed in these urinary bladders. In
immunohistochemical examinations, iNOS reacts as negative in the UPIII positive healthy urothelium which preserves the structure of
AUM. On the other hand positive reaction has been observed in AUM modified and UPIII negative urothelium. In these cases, as an
indicator of oxidative damage, 8-OHdG positivity was observed in the UPIII negative and iNOS positive areas. Additionally, increased
cell proliferation, decreased apoptosis as well as p53 disorganization were clearly observed in most of the cases. Thus, the active role
of nitric oxide, as a free radical derivative, has been shown in the enzootic hematuria cases of cattle.
