The aim of the present study was to investigate the prognostic significance of the expression of transcription factors, c-Fos, c-Jun and transmembrane protein CD147, in urothelial carcinoma of the bladder (UCB). The current study investigated the clinical significance of these factors in the development, progression and survival analysis of UCB. Immunohistochemistry was employed to analyze c‑Fos, c‑Jun and CD147 expression in 41 UCB cases and 34 non‑cancerous human bladder tissues. These results were scored in a semi‑quantitative manner based on the intensity and percentage of tumor cells that presented immunoreactivity. Protein levels of CD147, c‑Fos and c‑Jun expression were upregulated in 22 (53.7%), 10 (24.4%) and 9 (22.0%) UCB cases, respectively. High levels of c‑Jun correlated with the AJCC cancer staging manual (7th edition; P=0.038). Univariate analysis revealed that upregulated CD147 (P=0.038) or c‑Jun (P=0.008) was associated with poor overall survival (OS), respectively. Further analysis revealed that either CD147‑c‑Fos‑c‑Jun co‑expression (P=0.004), or CD147‑c‑Jun co‑expression (P=0.037) and c‑Fos‑c‑Jun co‑expression (P
