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.

Key metabolic pathway implicated in intractable form of breast cancer

July 18, 2011

Using a new in vivo screening system, Whitehead Institute researchers have identified a protein in a key metabolic pathway that is essential in estrogen receptor (ER)-negative breast cancer.

Opening the primary mouth with Wnt antagonists

May 4, 2009

Whitehead researchers have identified a novel mechanism that operates during formation of the “primary mouth”, the first opening between the outside of the embryo and the intestine.

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.
