Study Identifies Protein Complex Critical in Rapid Embryogenesis

December 11, 2003

For scientists who study embryonic development, insects, amphibians and marine invertebrates provide a unique window on the early stages of an embryo’s life. These organisms differ from higher life forms by having a simpler system for cell division, but it’s a system on fast forward: The embryos receive a maternal care package that permits their DNA replication and chromosome segregation to go into overdrive.

Robert Langer Appointed to Whitehead Institute Board of Directors

December 9, 2003

Robert Langer, the Kenneth J. Germeshausen professor of chemical and biomedical engineering at MIT, is a pioneer in biomedical engineering and author of more than 500 issued and pending patents. His research on drug delivery and tissue engineering serves as a foundation for today's $20 billion drug-delivery industry.

Yeast Helps Researchers Better Understand Parkinson's Mystery

December 4, 2003

Scientists know that in patients with Parkinson’s disease, certain proteins in the brain form clusters that somehow contribute to cell death and, eventually, lead to the onset of the disease’s debilitating symptoms. Whitehead scientists have succeeded in duplicating the disease’s most critical features in the most readily manipulated model organism in existence.

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.

Villa-Komaroff Named to TKT Board of Directors

December 2, 2003

Lydia Villa-Komaroff, chief operating officer and vice president for research at Whitehead Institute for Biomedical Research, has been named to the board of directors for Transkaryotic Therapies, Inc. (TKT), a Cambridge-based biopharmaceutical company.

Drivers of Discovery

November 25, 2003

A national report says postdoctoral researchers are "indispensable" to the advancement of science, a fact often overlooked by institutions and funding agencies. Now postdocs are pushing for change. And people are listening.

7 Million Letters and Counting

November 20, 2003

Almost 150 different genomes have been sequenced to date, including the human genome. But sequencing needs are growing faster than ever. This fall, researchers at Whitehead Institute will test new technology to speed genome sequencing.

Scientists Identify Dual Function for “Eyes absent”

November 19, 2003

Scientists know that proteins called transcription factors that regulate gene expression play a key role in cellular function. But what if that’s only part of the story? What if these regulators lead a double life no one knew before?

Whitehead Researchers Recognized for Scientific Contributions

November 18, 2003

The American Society of Human Genetics presented awards to Whitehead Member David Page and former graduate student Sjoerd Repping during its 53rd annual meeting, held recently in Los Angeles.

Study Identifies Potential New Source for Adult Stem Cells

November 13, 2003

In research reported in the online version of the journal Blood, Whitehead scientists report the discovery of a new blood stem cell growth factor. This discovery provides a new tool that allows researchers to multiply blood stem cells in culture for potential therapeutic use.

New Program Interrogates Gene Pathways

November 13, 2003

Any criminologist will tell you that witnesses, even the best intentioned, don’t always get it right. New software promises to do for biology what any criminal investigator would do at a crime scene: cross-examine witnesses until a single, coherent account of the event emerges.

Cholesterol Lowering Gene Increases Longevity

November 11, 2003

For years scientists have suspected that both longevity and low cholesterol are closely linked to genetics. This suspicion proves accurate in a new study to be published this week online in the Proceedings of the National Academy of Sciences, which shows genetic variation in a gene known for playing a key role in lipoprotein production also appears to be significantly overrepresented in centenarians.
