Scientists find evidence that cancer can arise from changes in the proteins that package DNA

Scientists find evidence that cancer can arise from changes in the proteins that package DNAMutations in histones, the proteins that shield and package DNA, have been linked to many types of cancer, but their role in promoting disease has not been clear. Now, for the first time, scientists have found that a change to the structure of a histone can trigger a tumor on its own. More »

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 … More »

Lifelong learning is made possible by recycling of histones, study says

Lifelong learning is made possible by recycling of histones, study saysResearchers have discovered a new mechanism that helps neurons make new connections with one another, the basis for learning. Their discovery focuses on one particular type of DNA-supporting protein, the histone H3.3, and its role regulating gene expression. More »

Odd histone helps suppress jumping genes in stem cells, study says

Odd histone helps suppress jumping genes in stem cells, study saysThe histone variant H3.3 appears to help keep certain genetic elements called retrotransponsons in place in the genome, preventing potentially harmful mutations in mouse embryonic stem cells, researchers have found. This discovery reveals a basic mechanism for epigenetics, or the control of inherited traits through means other than DNA. More »

Scientists identify protein that drives survival of gastrointestinal tumors

Since the introduction of Gleevec as a treatment for gastrointestinal stromal tumors, survival rates have climbed dramatically and recurrence has fallen by two-thirds. But over time, many patients develop resistance to the drug. Now, scientists at Rockefeller University and Memorial Sloan-Kettering Cancer Center have identified a molecule that acts as a survival factor for gastrointestinal tumors, a finding that may lead to next-generation therapies that can pick up where Gleevec leaves off.

Scientists track variant of gene-regulating protein in embryonic stem cells

The path to fully developed cells from embryonic stem cells requires that the right genes are turned on and off at the right times. New research from Rockefeller University shows that tiny variations between gene-regulating histone proteins play an important role in determining how and when genes are read. The finding shows that each region of the genome may be even more specialized than previously expected and may open a new avenue of investigation regarding the mysterious causes of the human genetic disease known as ATR-X syndrome.
