Latest Histone Stories
A new study reveals that two enzymes help immune cells deploy pathogen-killing traps by unraveling and using the chromatin (DNA and its associated proteins) contained in the cells' nuclei to form defensive webs.
The genetic inherited material DNA was long viewed as the sole bearer of hereditary information.
Post-translational modifications of histones play an important role in regulating chromatin dynamics and function.
Like cats, human cells have a finite number of lives-once they divide a certain number of times (thankfully, more than nine) they change shape, slow their pace, and eventually stop dividing, a phenomenon called "cellular senescence".
By creating a "map" of histone modifications in fat cells, investigators have discovered two new factors that regulate fat formation, a key step on the road to better understanding obesity, diabetes and other metabolic disorders.
Stress has become one of the major disease states in the developed world.
On average, one hundred billion cells in the human body divide over the course of a day.
The DNA genomes of organisms whose cells possess nuclei are packaged in a highly characteristic fashion.
Malfunction of a protein has been linked to a form of mental retardation that affects up to one out of every 500 males, says Nasser K. Yaghi, a Texas A&M University magna cum laude biology graduate who was selected to participate in a medical research project at Harvard that has been published in the journal Nature.
A subtle mutation affecting the epigenome â€“ a set of dynamic factors that influence gene activity -- may lead to an inherited form of mental retardation that affects boys, find researchers at Children's Hospital Boston.
