C. David Allis wins the 2015 Breakthrough Prize in Life Sciences

C. David Allis wins the 2015 Breakthrough Prize in Life Sciences’Allis is recognized for his foundational research on the unexpected regulation of gene activation by modifications to proteins that package DNA, work with implications for many diseases including cancer. The Breakthrough Prize is worth $3 million, making it the richest prize in the life sciences, roughly double the Nobel Prize. More »

New technique reveals a role for histones in cell division

New technique reveals a role for histones in cell divisionResearchers have found that key aspects of cell division, such as the formation of the support structure for the envelope that surrounds the nucleus, depend on the presence of DNA-organizing proteins known as histones. More »

David Allis, pioneer in epigenetics, to receive prestigious Japan Prize

Allis’s discovery that chemical “tags” bind to specific sections of histone proteins in order to activate or silence nearby genes has ignited the field of epigenetics, a relatively new area of study which explores the inheritance of physical changes that cannot be traced back to mutations in the DNA sequence. The Japan Prize, worth approximately half a million dollars, is among the most prestigious prizes in science. More »

Mechanism of mutant histone protein in childhood brain cancer revealed

Scientists in David Allis’s laboratory have shown how a mutated histone protein inhibits an enzyme, which normally keeps cell growth in check, and causes a rare form of pediatric brain cancer called DIPG. Their findings reveal a mechanism for inhibiting enzymes and could lead to the development of pharmaceuticals that mimic the action of these mutant proteins.

Influenza “histone mimic” suppresses antiviral response

Researchers have discovered a novel mechanism by which influenza viruses hijack key regulators of the human body’s normal antiviral response in order to slip by it undetected. The results have major implications for our understanding of the biology of the seasonal influenza virus and suggest a possible target for a new class of antiviral and anti-inflammatory drugs.

More Than Just Packaging, Histones Help Turn Genes On

Histones, the proteins that help roll several feet of DNA into the microscopic span of a single nucleus, are turning out to be much more than just packaging material. Instead, recent studies indicate that these once underrated proteins actively participate in switching genes “on” — a vital life process occurring at all times in each one of our cells. More »
