Revising the Meaning of “Prion”

Using an unbiased screen in yeast, a team of Whitehead Institute and Stanford University scientists have identified dozens of prion-like proteins that could change the defining characteristics of these unusual proteins.

Inherited Parental Methylation Shifts Over Time, May Have Functional Effects in the Brain and Other Tissues

Inherited methylation—a form of epigenetic regulation passed down from parents to offspring—is far more dynamic than previously thought and may contribute to changes in the brain and other tissues over time. This finding by Whitehead Institute...

Genome-Wide Toxoplasma Screen Reveals Mechanisms of Parasitic Infections

Whitehead Institute researchers have conducted the first genome-wide screen in Apicomplexa, a phylum of single-celled parasites that cause diseases such as malaria and toxoplasmosis. The screen sheds light into the vast, unstudied reaches of...

Novel Method Enables Absolute Quantification of Mitochondrial Metabolites

Whitehead Institute scientists have developed a method to quickly isolate mitochondria from mammalian cells and systematically measure the concentrations of mitochondrial metabolites. Mitochondrial dysfunction is found in several disorders,...

Disrupting Mitochondrial Function Could Improve Treatment of Fungal Infections

Whitehead Institute scientists have identified a potential antifungal mechanism that could enable combination therapy with fluconazole, one of today’s most commonly prescribed fungal infection treatments. Severe, invasive fungal infections have a...

Defining What It Means to Be a Naive Stem Cell

Whitehead Institute scientists have created a checklist that defines the “naive” state of cultured human embryonic stem cells (ESCs). Such cells provide a better model of early human embryogenesis than conventional ESCs in later stages of...

Tiny Alpaca-Derived Antibodies Point to Targets Preventing Viral Infection

Using tiny, alpaca-derived, single-domain antibody fragments, Whitehead Institute scientists have developed a method to perturb cellular processes in mammalian cells, allowing them to tease apart the roles that individual proteins play in these...

Identifying a Genetic Mutation Behind Sporadic Parkinson’s Disease

Using a novel method, Whitehead Institute researchers have determined how mutations that are not located within genes are identified through genome-wide association studies (GWAS) and can contribute to sporadic Parkinson’s disease, the most common...
