Abstract:
Application of siRNA to knockdown a specific gene requires target mRNA accessibility, effective intracellular delivery of siRNA into target cells and potent siRNA inhibition of target mRNA. Use of siRNA as a tool is advancing in almost every field of biomedical research, but some of the most dynamic and exciting applications of siRNA are in cancer research. This review summarizes the results obtained with siRNA in cancer, in particular functional validation of tumorigenic genes in cell culture and animal tumor models, effective siRNA delivery systems, efficiency of siRNA agents compared with antisense oligonucleotides and efforts for potential therapeutic development. Along with the rapidly growing literature on using siRNA as a functional genomic tool, there is emerging evidence that siRNA may represent a novel therapeutic modality for cancer treatment when optimized local and systemic delivery systems are available.
