The dynamic properties of RNA interference (RNAi) in cancer biology have led investigators to pursue with significant interest its role in tumorigenesis and cancer therapy. We recently reported that decreased expression of key RNAi enzymes, Dicer and Drosha, in epithelial ovarian cancers was associated with poor clinical outcome in patients. Dicer expression was also functionally relevant in that targeted silencing was limited with RNAi fragments that require Dicer function compared with those that do not. Together, this and other studies suggest that RNAi machinery expression may affect key pathways in tumorigenesis and cancer biology. Understanding alterations in the functional RNAi machinery is of fundamental importance as we strive to develop novel therapies using RNAi strategies.
RNA 干扰 (RNAi) 在癌症生物学中的动态特性促使研究人员对其在肿瘤发生和癌症治疗中的作用产生了浓厚的兴趣。我们最近报道称，上皮性卵巢癌中关键 RNAi 酶 Dicer 和 Drosha 的表达降低与患者临床预后不良相关。Dicer 的表达在功能上也是相关的，因为与不需要 Dicer 功能的 RNAi 片段相比，靶向沉默受到限制。这些研究和其他研究表明，RNAi 机制的表达可能会影响肿瘤发生和癌症生物学中的关键途径。了解功能性 RNAi 机制的改变对于我们努力使用 RNAi 策略开发新的治疗方法至关重要。
