Abstract

The present study aimed to investigate the expression of cyclin D1 and cyclin E in tissue chips of bladder cancer using quantum dots (QDs), as well as examine its clinicopathological significance. The QD‑based immunofluorescence tissue chemical technique was adopted to detect cyclin D1 and cyclin E expression in 75 tissue chips of human urothelial bladder carcinoma (including 70 cases of urothelial bladder carcinoma and 5 cases of cystitis), and its correlation with clinicopathological features was analyzed. The positive rates of cyclin D1 and cyclin E expression in urothelial bladder carcinoma were 68.6% (48/70) and 70.0% (49/70), respectively; however, no expression was observed in cystitis. Based on the results of statistical analysis, the difference in the positive rates of cyclin D1 and cyclin E expression between urothelial bladder carcinoma and cystitis was significant (P<0.05). QD staining and statistical analysis revealed that the expression of cyclin D1 and cyclin E in urothelial bladder carcinoma was significantly higher compared with that in cystitis (P<0.05). However, no statistically significant difference (P>0.05) in cyclin D1 expression was observed in relation to pathological stage, clinical stage or invasion of urothelial bladder carcinoma; however, there was a significant difference (P<0.05) in cyclin E expression with respect to these factors. These results demonstrated that overexpression of cyclin D1 may be an early event in the occurrence of urothelial bladder carcinoma. Cyclin D1 may play a role in the initial stage where cell proliferation is a necessary step, without invasion or metastasis. In addition, overexpression of cyclin E was correlated with the stage and depth of invasion of urothelial bladder carcinoma. In conclusion, the abnormal expression of cyclin D1 and cyclin E may be involved in the occurrence and development of urothelial bladder carcinoma.
