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.  

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.

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.

Whitehead Institute researchers have identified an area in the developing face of embryonic frogs that unzips to form the mouth. The scientists, who named this region the “pre-mouth array”, have also discovered the cellular signaling that triggers its formation. Elucidating this critical aspect of craniofacial development in a model organism enhances understanding of and potential treatment for human facial birth defects.
