Scientists create germ cell-supporting embryonic Sertoli-like cells from skin cells

September 6, 2012

Using a stepwise trans-differentiation process, Whitehead Institute researchers have turned skin cells into embryonic Sertoli-like cells.

Protein found to regulate red blood cell size and number

August 28, 2012

By examining the results of genome-wide association studies (GWAS) in conjunction with experiments on mouse and human red blood cells (RBCs), researchers in the lab of Whitehead Institute Founding Member Harvey Lodish have identified the protein cyclin D3 as regulating the number of cell divisions RBC progenitors undergo, which ultimately affects the resulting size and quantity of RBCs.

Heat-shock factor reveals its unique role in supporting highly malignant cancers

August 2, 2012

Whitehead Institute researchers have found that an ancient, highly conserved cell survival factor drives expression of a specific set of genes that is strongly associated with metastasis and death in patients with breast, colon, and lung cancers.

Planarians offer a better view of eye development

August 2, 2012

Whitehead Institute researchers have created a complete catalog of genes active in the planarian eye. Several identified genes are known to have versions that play a role in the vertebrate eye, including genes involved in eye development and others associated with age-related macular degeneration and Usher syndrome, a disorder that causes progressive retinal degradation.

Structure of RNAi complex now crystal clear

June 20, 2012

Researchers at Whitehead Institute and Memorial Sloan-Kettering Cancer Center have defined and analyzed the crystal structure of a yeast Argonaute protein bound to RNA.

Breast cancer clinical trial to test combination of heat shock protein inhibitor and hormonal therapy

May 22, 2012

A clinical trial involving collaboration between researchers at Whitehead Institute and Dana Farber Cancer Institute is now enrolling patients with recurrent or metastatic estrogen receptor-positive (ER+) breast cancer.

Whitehead Member Richard Young elected to National Academy of Sciences

May 1, 2012

The National Academy of Sciences announced today that Whitehead Institute’s Richard Young is among 84 new Academy members elected in recognition of distinguished and continuing achievements in original research.

lobSTR algorithm rolls DNA fingerprinting into 21st Century

April 27, 2012

Whitehead Institute researchers have created a three-step algorithm, lobSTR, that in one day accurately and simultaneously profiles more than 100,000 short tandem repeats (STRs) in one human genome sequence—a feat that previous systems could never complete.

Once again, Whitehead Institute is the best place for postdocs

March 29, 2012

For the second year in a row, Whitehead Institute has been dubbed the best place in the United States for postdoctoral researchers to work. The honor was bestowed by The Scientist magazine, which conducts an annual survey of postdocs at research institutions internationally.

On the path to age-defying therapies

March 29, 2012

By teasing apart rapamycin’s activity at the cellular level, researchers at Whitehead Institute and the University of Pennsylvania have determined that inhibiting only the protein cluster known as the mechanistic target of rapamycin complex 1 (mTORC1) prolongs life in mice without adversely affecting glucose tolerance or insulin sensitivity.

Whitehead Director talks Y chromosome with Stephen Colbert

March 27, 2012

Whitehead Institute Director David Page appeared last night on Comedy Central's The Colbert Report to engage in a little lively banter about the future of the human Y chromosome.
