MicroRNAs Move Into Cancer Research

Tracy Hampton, PhD

JAMA. 2005;294:411-412.

Since this article does not have an abstract, we have provided the first 150 words of the full text and any section headings.

With the goal of understanding and manipulating the behavior of cells gone awry, many cancer researchers have turned to the gene-silencing technique known as RNA interference with the hope of using the approach to effectively mute the expression of genes that drive malignancies. Now, three new studies in the June 9 issue of Nature point to naturally occurring roles of interfering RNAs called microRNAs in cancer development, findings that could one day lead to new diagnostics and therapies.

The studies "change the landscape of cancer genetics," wrote Paul Meltzer, MD, PhD, of the National Human Genome Research Institute, in Bethesda, Md, in an accompanying News and Views article (Meltzer. Nature. 2005;435:745-746).


Tiny, naturally occurring bits of RNA called microRNAs can play a role in cancer. When scientists injected cells expressing certain microRNAs into mice, fluorescence revealed that tumors arose more quickly and were more disseminated (left) . . . [Full Text of this Article]
