Abstract

The present study aimed to evaluate the impact of small interfering RNA (siRNA) targeting of the survivin gene in human tumor cells and the effect of decreased survivin expression on the proliferation and apoptosis of tumor cells. Human tumor cell lines (MSA‑MB‑231, SGC‑7901, HeLa, A549, SK‑OV‑3 and Raji, PC‑3) were cultured in vitro and divided into three groups: survivin siRNA‑treated, scrambled negative control siRNA‑treated and an untreated control group. The level of survivin mRNA and protein expression was subsequently determined by reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively. Cell proliferation was also examined by an MTT assay following transfection and the apoptotic rate of cells was detected by Hoechst and Annexin V/propidium iodide staining. It was observed that relative to the control group, expression of survivin mRNA and protein in the survivin siRNA‑treated group was significantly downregulated. Furthermore, siRNA targeting of survivin lead to the inhibition of tumor cell proliferation, as well as an increase in their apoptotic rate in vitro. These data suggest that survivin may be a potential tumor biomarker and a novel target for the treatment of cancer.
