Diagram of how editing methylation can change cells

Scientists use CRISPR/Cas9 to flip DNA methylation states in vivo

Whitehead Institute scientists have deciphered how to use a modified CRISPR/Cas9 gene editing system to change genes’ methylation state, thereby activating or silencing those genes. Proper methylation is critical for normal cellular operations and altered methylation has been linked to many diseases, including neurological disorders and cancer.

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 scientists challenges current understandings of gene regulation via methylation, from development through adulthood.

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 parasite genomes, uncovering for instance a protein common to all apicomplexans.

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, including Parkinson’s disease, cardiovascular disease, and mitochondrial diseases. Until now, peering into the inner metabolic workings of these vital organelles has been very challenging.

Disrupting mitochondrial function could improve treatment of fungal infections

By identifying new compounds that selectively block mitochondrial respiration in pathogenic fungi, 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 mortality rate of 30-50% and cause an estimated 1.5 million deaths worldwide annually. Current antifungal therapies are hampered by the increasingly frequent emergence of drug resistance and negative interactions that often preclude combination use.
