Whitehead Institute Member Jonathan Weissman and colleagues used large-scale systematic genetic screens to identify the molecules and pathways that populate the mitochondrial surface with important and diverse signaling proteins. They deciphered the logic by which the cell ensures the proper delivery of these proteins. These findings may have important implications for understanding the impact on health and disease when these processes go awry.
Whitehead Institute Member Jonathan Weissman and collaborators developed a tool to reconstruct the family trees and individual states of cells in humans, revealing how blood cell production changes in old age.
Whitehead Institute Founding Member Rudolf Jaenisch and colleagues found that SARS-Cov-2 can infect sensory neurons and alter their gene expression. This may help to explain the peripheral nervous system symptoms associated with Covid-19, such as loss of smell.
Once considered genomic “junk,” repetitive sequences in DNA are being discovered to have important roles in our biology. Whitehead Institute researchers are investigating different types of these repeated sequences, from repetitive DNA regions to excessive repeats within genes, in order to understand what roles they play in cells and how they contribute to health and disease.
In an increasingly interconnected and complex world, collaboration is more important than ever for progress in science. By coming together, scientists can share knowledge and ideas to solve complex problems, learn new skills, and advance their careers. Researchers at Whitehead Institute recognize the importance of collaboration when taking on big challenges in science.
Whitehead Institute Founding Member Rudolf Jaenisch and colleagues have developed molecular genetic tools that can rescue neurons affected by Rett syndrome, a neurodevelopmental disorder linked to intellectual disability.
Whitehead Institute researchers find a role for condensates, droplets involved in corralling proteins inside of cells, in disease. They provide a catalog of disease-causing mutations that likely affect condensates as a resource for future research.
A group of researchers from multiple universities, including Whitehead Institute Member Olivia Corradin, gained new insights into the genetics of opioid overdose risk by looking at changes in gene regulation in the brain.
Introducing Sinisa Hrvatin, who joined Whitehead Institute as a Member this year. Hrvatin, who completed his postdoc at Harvard Medical School, studies how cells initiate, regulate, and survive states of stasis, including hibernation.
