title: RNA interference targeting Aurora-A sensitizes glioblastoma cells to temozolomide chemotherapy.
abstract: Clinically, temozolomide (TMZ) is widely used in glioblastoma (GBM) treatment. However, the toxicity of TMZ may influence the quality of patient life. Thus, novel treatment options for sensitizing GBM cells to TMZ chemotherapy are necessary. Aurora-A is widely expressed in GBM and correlated with poor prognosis. It has been proven to be an effective target for gene therapy and chemotherapy. In the present study, short hairpin (sh)RNA targeting Aurora-A was employed to knockdown Aurora-A expression in GBM cells. Cell Counting Kit-8 assays, flow cytometry, colony formation assays, invasion assays and tube formation assays were used to determine the effects of Aurora-A knockdown when combined with TMZ treatment. A U251 subcutaneous cancer model was established to evaluate the efficacy of combined therapy. The results of the present study indicated that the proliferation, colony formation, invasion and angiogenesis of GBM cells were significantly inhibited by combined therapy when compared with TMZ treatment alone.In vivoresults demonstrated that knockdown of Aurora-A significantly (P=0.0084) sensitizes GBM cells to TMZ chemotherapy. The results of the present study demonstrated that knockdown of Aurora-A in GBM cells enhances TMZ sensitivityin vitroandin vivo. Therefore, Aurora-A knockdown may be a novel treatment option for decreasing TMZ toxicity and improving patient quality of life.
