Scientists find evidence that cancer can arise from changes in the proteins that package DNA
A mutation that affects the proteins that package DNA鈥攚ithout changing the DNA itself鈥攃an cause a rare form of cancer, according to new findings in this week鈥檚 Science from researchers at 鸟大大影院. The mutation is present in histones, the protein scaffolding around which DNA w...
C. David Allis receives the 2016 Gruber Genetics Prize
C. David Allis, Joy and Jack Fishman Professor and head of the Laboratory of Chromatin Biology and Epigenetics, has won the 2016 Gruber Genetics Prize. He shares the $500,000 award with Michael Grunstein of the University of California, Los Angeles. The award, given by The Gruber Foundation, reco...

An experimental Alzheimer鈥檚 drug reverses genetic changes thought to spur the disease
Aging takes its toll on the brain, and the cells of the hippocampus鈥攁 brain region with circuitry crucial to learning and memory鈥攁re particularly vulnerable to changes that can lead to Alzheimer鈥檚 disease or cognitive decline. With the hope of counteracting the changes that can lead to these t...
In the News - The New Yorker - Allis
Same but Different: How epigenetics can blur the line between nature and nurture "Allis walked me to his lab, a fluorescent-lit space overlooking the East River, divided by wide, polished-stone benches. A mechanical stirrer, whirring in a corner, clinked on the edge of a glass beaker. 'Two featur...
Mice engineered with rare kidney disease provide new insights about how cells repair broken DNA
Like jewels in a vault, our precious genetic material is stored in the nucleus of a cell鈥攕equestered away from potentially damaging cellular components and toxins so that no harm can come to it. Yet over the course of a life moving through this world, our DNA does get damaged, and our cells have ...
A common brain cell shapes the nervous system in unexpected ways
More than half of our brains are made up of glial cells, which wrap around nerve fibers and insulate them鈥攕imilarly to how the plastic casing of an electric cable insulates the copper wire within鈥攁llowing electrical and chemical impulses to travel faster. In the past, neuroscientists considered ...
A newly discovered way for cells to die
Some cells are meant to live, and some are meant to die. The linker cell of Caenorhabditis elegans, a tiny worm that is a favored model organism for biologists, is among those destined for termination. This cell helps determine the shape of the gonad in male worms鈥攁nd then it dies, after two days...
