Key nutrient sensor identified for cellular pathway linking nutrient availability to cell growth

Whitehead Member David Sabatini has identified the methionine sensor in the mTOR pathway, which is a crucial metabolic pathway in cells. His work provides interesting data suggesting that the anti-aging and anti-diabetes effects of low methionine and mTOR inhibition may be connected.

Small worm muscles up to reveal ancient body patterning mechanism during regeneration

Whitehead Member Peter Reddien has determined that a major function of muscle in planaria and acoels--a small regenerative marine worm auspiciously located on the evolutionary tree as an outgroup to all the rest of the Bilateria--is to serve as the source of instructive positional information for instructing regeneration.

Stuck on the membrane: A pro-metastatic transcription factor’s journey from anonymity to a promising target for breast cancer therapy

Whitehead Member Piyush Gupta has identified a protein stuck in the cell membrane that plays an important role in a cellular pathway crucial for cancer metastasis. The protein is a potential new target for breast cancer therapy that targets the cancer cells' metastatic behavior.

Study reveals key molecular link in major cell growth pathway

A team of scientists led by Whitehead Institute has uncovered a surprising molecular link that connects how cells regulate growth with how they sense and make available the nutrients required for growth.  The researchers’ findings also implicate a new protein, SLC38A9, as a potential drug target in pancreatic cancer.

Genetic body/brain connection identified in genomic region linked to autism

For the first time, Whitehead Institute scientists have documented a direct link between deletions in two genes—fam57ba and doc2a—in zebrafish and certain brain and body traits, such as seizures, hyperactivity, large head size, and increased fat content. Both genes reside in the 16p11.2 region of the genome, which has been linked to multiple brain and body disorders in humans, including autism spectrum disorder, developmental delays, seizures, and obesity.

Mystery solved: how thyroid hormone prods red blood cell production

For more than a century, the link between thyroid hormone and red blood cell production has remained elusive. Now, Whitehead scientists have teased about the mechanism that connects them, which could help scientists identify new therapies for specific types of anemia.

Elegant switch controls translation in transition from egg to embryo

The transition from an egg to a developing embryo is one of life’s most remarkable transformations. Now Whitehead Institute researchers have used fruit flies to decipher how one aspect—control of the translation of messenger RNAs (mRNAs) into proteins—shifts as the egg becomes an the embryo.  This type of switch could tell scientists more about how human cells work and embryos develop.

Growth medium based on human plasma rewires cell metabolism

Cultured human cells are the foundation for disease and drug research. Now Whitehead Institute researchers have designed a growth medium that more closely resembles the cells’ environment in the body—and demonstrated that, relative to decades-old recipes that have remained the workhorses of cell culture studies, it significantly alters the cells’ inner workings.

Biomarker identified for likely aggressive, early stage breast cancer

Whitehead Institute scientists have identified a gene that could help clinicians discern which patients have aggressive forms of early stage breast cancer, which could prevent hundreds of thousands of women from undergoing unnecessary treatment and save millions of dollars.

Cargo-carrying red blood cells alleviate autoimmune diseases in mice

Using red blood cells modified to carry disease-specific antigens, a team of scientists from Whitehead Institute and Boston Children’s Hospital have prevented and alleviated two autoimmune diseases—multiple sclerosis (MS) and type 1 diabetes—in early stage mouse models.  This research is an exciting step toward therapeutics for autoimmune diseases, which affect an estimated 23 million Americans.

Researchers uncover a role for HSP90 in gene-environment interactions in humans

Researchers at Whitehead Institute have now uncovered a role for the protein-folding chaperone HSP90 in humans, not only as a modifier of the effects of mutations, but as a mediator of the impact of the environment on the function of mutant proteins. And these effects of HSP90 can alter the course of human diseases.

Researchers chart global genetic interaction networks in human cancer cells

Investigators at Whitehead Institute and the Broad Institute have succeeded in identifying the set of essential genes—those required for cellular proliferation and survival—in each of 14 human acute myeloid leukemia (AML) cell lines that had previously been characterized by genome sequencing. By combining their “gene essentiality map” with the existing genomic information, their study revealed liabilities in genetically defined subset of cancers that could be exploited for new therapies.

New Clues on the Basis of Parkinson’s Disease and Other “Synucleinopathies”

Parkinson’s disease (PD) and other “synucleinopathies” are known to be linked to the misfolding of alpha-synuclein protein in neurons. Less clear is how this misfolding relates to the growing number of genes implicated in PD through analysis of human genetics. Two new studies from researchers affiliated with Whitehead Institute and Massachusetts Institute of Technology explain how they used a suite of novel biological and computational methods to shed light on the question.

Scientists engineer gene pathway to grow brain organoids with surface folding

Whitehead researchers provide insight into a specific gene pathway that appears to regulate the growth, structure, and organization of the human cortex. They also demonstrate that 3D human cerebral organoids--miniature, lab-grown versions of specific brain structures--can be effective in modeling the molecular, cellular, and anatomical processes of human brain development. And they suggest a new path for identifying the cells affected by Zika virus.
