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.  

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 form of the condition. The approach could be used to analyze GWAS results for other sporadic diseases with genetic causes, such as multiple sclerosis, diabetes, and cancer.

The American Association for Cancer Research (AACR) announced today that Whitehead Institute Founding Member Rudolf Jaenisch is one of 11 newly elected Fellows of the AACR Academy.

Whitehead Institute researchers have created a new mouse-human modeling system that could be used to study neural crest development as well as the modeling of a variety of neural crest related diseases, including such cancers as melanoma and neurofibromatosis. 

Whitehead Institute researchers have developed a tool that allows scientists to monitor changes in DNA methylation over time in individual cells. Certain diseases, including cancer, cause changes in DNA methylation patterns, and the ability to document these alterations could aid in the development of novel therapies.

The prize honors Jaenisch’s groundbreaking body of work in epigenetics, the development of transgenic animals, and the generation and use of induced pluripotent stem (iPS) cells.

A widely conserved family of RNA-binding proteins known to be expressed in neural stem cells and other stem cell types has now been shown to play a role in controlling both the state and behavior of breast cancer cells.
