MicroRNA helps prevent tumors

February 22, 2007

A microRNA directly regulates a gene implicated in human cancers.

When RNA rules

May 5, 2006

A newly discovered class of molecules plays an astonishingly powerful role in biology.

MicroRNAs shape evolution of most genes

November 29, 2005

Researchers in the lab of Whitehead Institute Member David Bartel have found that a class of small RNAs called microRNAs influence the evolution of genes far more widely than previous research had indicated.

David Bartel honored by French academy

June 15, 2005

Whitehead Institute Member David Bartel is one of two scientists to receive the annual Louis-D. Prize from the Institut de France, an organization similar in many respects to the National Academy of Sciences in the United States.

David Bartel wins HHMI appointment

March 22, 2005

2005 is off to a good start for Whitehead Member David Bartel. In January, he and his colleagues published a landmark paper in the journal Cell. A week later he was honored with the National Academy of Science's prestigious Award in Molecular Biology. And in March, Bartel was appointed Investigator for the Howard Hughes Medical Institute (HHMI).

David Bartel receives NAS Award in Molecular Biology

January 27, 2005

The U.S. National Academy of Sciences has recognized the work of Whitehead Member and MIT Professor of Biology David Bartel by presenting him the NAS Award in Molecular Biology. Each year a medal and a prize of $25,000 goes to a young scientist for a recent notable discovery in molecular biology.

One-third of human genome regulated by RNA

January 14, 2005

Researchers from Whitehead Institute for Biomedical Research and Massachusetts Institute of Technology have discovered that a kind of RNA molecule called microRNA regulates more than 5,300 human genes, or nearly one-third of the genome’s protein coding regions.

New study examines microRNA’s in plants and animals

May 19, 2004

As genes and proteins continue to take center stage in molecular biology, molecules called microRNAs are starting to make inroads. These microRNAs, which are unusually small when compared to other RNAs in the cell, have captured the attention of biologists with their capacity to regulate genes, an ability that one day may have therapeutic value.

New method identifies human microRNA targets

January 28, 2004

Research into the mechanics of microRNAs, tiny molecules that can selectively silence genes, has revealed a new mode of gene regulation that scientists believe has a broad impact on both plant and animal cells.

MicroRNAs Play a Role in Blood Formation, Study Finds

December 4, 2003

Scientists have been fascinated by miRNAs ever since the abundance of these tiny RNAs was discovered in 2001. Rather than code for proteins, miRNAs serve as regulators that turn protein-coding genes off. Now, new studies by scientists at Whitehead Institute for Biomedical Research are offering insight into the role miRNAs play in mammalian development.

Laboratory “Theme Park” Re-creates RNA World for Study

August 26, 2003

Rarely, if ever, are theme parks built around a biological theme – and never do such parks fit inside a test tube. Almost never. Scientist David Bartel is hard at work on what might seem an impossibility – a microscopic theme park whose motif, the origins of life, is of equal interest to both scientists and philosophers.
