The team developed a siRNA product that specifically blocks the transcription of the gene that codes for IL-8, thereby blocking production of this protein, and encases it in a liposome delivery system. In mouse studies, this product showed activity against 2 ovarian cancer cell lines, both when used alone and when used in combination with docetaxel. In addition, the mouse studies revealed that the product was decreasing tumor growth through anti-angiogenic mechanisms — the treated tumors showed a lower microvessel density, the researchers report. This product was "highly effective in our preclinical studies and may merit clinical development," they write. However, they also caution that the cell lines used to create the mouse models might not accurately reflect the heterogeneity seen in human tumors.

该团队发展一种siRNA产品,特别阻断IL-8的基因转译密码,因此阻断此一蛋白质之产生,且将它包入一个微脂粒传递系统;在老鼠研究中,不论单独使用或者和docetaxel并用,此产品显示对两种卵巢癌细胞线有活性;此外,老鼠研究发现此产品可透过抗血管新生机转减少肿瘤生长—报告指出,治疗的肿瘤显示较少的微血管密度,此产品在我们的临床前研究中相当有效,值得临床发展;不过,他们也表示,所用的老鼠研究中的细胞线可能无法精准反应人类肿瘤的异质性。
