Purpose: T investigated the inducible response of transcription factor Nuclear Factor
Kappa B(NF¥êB) ,in response to lipopolysaccharide(LPS), interferons(INFs), and tumor
necrosis factor(TNF) on the normal urothelial cells derived from ureter and the bladder.
Materials and Methods: Urothelial cells were harvested from the ureter and the
bladder, cultured, passaged ,and expanded in serum free medium. Immunostaining of the
urothelial cells with reacting anti-cytokeratin antibodies was done no to identify a stable
epithelial phenotype. Cultured human urothelial cells were either untreated and treated
with LPS, INF¥ã, INF¥á and TNF¥á. Cell extracts were prepared and used for
electrophoretic mobility shift assay (EMSA) using PRO ¥±-¥öB as probes for NF¥öB
respectively.
Results : We cultured urothelial cells successfully confirmed by immunohistochemical
staining. In both urothelial cell types, NF¥öB bindings with their respective were induced
by treatment with LPS, INF¥ã and TNF¥á. NF¥öB was weakly induced by INF¥á. For
the NF¥öB complex, a distinctly different migrating pattern of the NF¥öB was noted
between the different urothelial cells.
Conclusions: Many urothelial diseases are unique to specific areas of the urinary
collecting system. The characterization of different inducible responses of transcription
factors involved in cytoplasmic and nuclear signaling of genes encoding immunologically
relevant proteins provide a unique opportunity for understanding disease presentation and
designing specific treatment interventions.
