Small RNA molecules, including microRNAs (miRNAs) and small interfering RNAs (siRNAs), offer tremendous potential as new therapeutic agents to inhibit cancer-cell growth. However, delivering these small RNAs to solid tumors remains a…

Sequencing the genomes of tumor cells has revealed thousands of mutations associated with cancer. One way to discover the role of these mutations is to breed a strain of mice that carry the genetic flaw — but breeding such mice is an…
