Abstract

Renal cell carcinoma is the most frequent kidney malignancy and patients with metastatic disease have a poor prognosis. Suppressed apoptosis and marked invasiveness are distinctive features of renal cell carcinoma. In the present study, a dual‑regulated oncolytic adenovirus expressing the interluekin (IL)‑24 gene (Ki67‑ZD55‑IL‑24) was constructed utilizing the Ki67 promoter to replace the native viral promoter of the E1A gene. Whether the combination of Ki67‑ZD55‑IL‑24‑mediated gene virotherapy and radiotherapy produced increased cytotoxicity in renal cell carcinoma cells via mitochondrial apoptotic cell death was investigated. The data indicated that this novel strategy has the potential to be further developed into an effective approach to treat renal cell carcinoma. The results showed that the combination of Ki67‑ZD55‑IL‑24 and radiotherapy significantly enhanced anti‑tumour activity via increasing the induction of apoptosis in melanoma cells compared with the other agents.
