BACKGROUND: Our previous studies have demonstrated potent oncolysis efficacy of the E1A, E1B double-restricted replication-competent oncolytic adenovirus AxdAdB-3 for treatment of bladder cancer. Here, we reported the feasibility and efficacy of AxdAdB-3 alone, or in combination with gemcitabine for treating renal cell carcinoma.
METHODS: Cytopathic effects of AxdAdB-3 were evaluated in human renal cell carcinoma cell lines TOS-1, TOS-2, TOS-3, TOS-3LN, SMKT-R3, SMKT-R4 and ACHN, and in normal human renal proximal tubule epithelial cells (RPTEC). AxdAdB-3 induced down-regulation of the cell cycle was determined by flow cytometry. Combination therapies of AxdAdB-3 with gemcitabine were evaluated in vitro and in vivo on subcutaneous TOS-3LN tumors in a severe combined immunodeficiency disease (SCID) mouse model.
RESULTS: AxdAdB-3 was potently cytopathic against the tested most renal cell carcinoma cell lines including TOS-2, TOS-3, TOS-3LN, SMKT-R3 and SMKT-R4, while normal human RPTEC were not destroyed. AxdAdB-3 effectively induced cell cycle S-phase entry. Combined therapy of AxdAdB-3 with gemcitabine demonstrated stronger antitumor effects in vitro and in vivo compared with either AxdAdB-3 or gemcitabine alone.
CONCLUSION: AxdAdB-3 alone, or in combination with gemcitabine may be a promising strategy against renal cell carcinoma.
