Abstract

Survivin has been overexpressed in numerous types of cancer and is associated with a poor clinical outcome. A number of various approaches have been used to counteract survivin in order to inhibit tumor growth or promote cell apoptosis. The present study aimed to evaluate the efficiency and antitumor effect of a survivin‑targeted short interfering RNA (siRNA) delivery system using lipid nanoparticles for the treatment of colon cancer. Survivin siRNA (si‑survivin) nanoliposomes were prepared and transfected into LoVo cells. The mRNA expression level of survivin was determined by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) and western blot analysis. Cell viability was evaluated by MTT assay. LoVo‑bearing nude mice were treated with si‑survivin intratumorally or intravenously. Tumor growth in LoVo‑bearing mice was monitored and recorded, and tumor samples were obtained for evaluation of survivin expression levels using RT‑qPCR, western blotting and immunohischemical staining. The expression level of survivin was significantly reduced by nanoliposomal si‑survivin along with cell proliferation inhibition in vitro. Intravenous administration of si‑survivin nanoliposomes may significantly inhibit tumor growth with less toxicity compared with doxorubicin hydrochloride treatment in LoVo‑bearing mice. Nanoliposomal si‑survivin may significantly reduce the expression level of survivin and inhibit cell proliferation of colon cancer cells in vitro and in vivo. si‑survivin delivered by lipid nanoparticles may be a potential treatment approach for colon cancer.
