New Clues To How Stem Cells Form
April 16, 2009 — A study on the nematode C. elegans shows some of the first direct evidence of a process required for epigenetic reprogramming between generations -- a finding that could shed more light on the ... > full story -
The New 'Epigenetics:' Poor Nutrition In The Womb Causes Permanent Genetic Changes In Offspring
April 13, 2009 — New research explains how poor maternal nutrition passes health risk across generations. The new science of epigenetics explains how genes can be modified by the environment: You are what your mother ... > full story -
Epigenetics: DNA Isn’t Everything
April 12, 2009 — Research into epigenetics has shown that environmental factors affect characteristics of organisms. These changes are sometimes passed on to the offspring. Does this in any way oppose Darwin's theory ... > full story -
Definition Of 'Epigenetics' Clarified
April 1, 2009 — Scientists are working to develop an operational definition of "epigenetics" -- a rapidly growing research field that investigates heritable alterations in gene expression caused by mechanisms other ... > full story -
Cancer Mutations In The Heart Of Gene Regulation
March 29, 2009 — Researchers have identified a new cancer gene -- one that is common to many cancers and affects the most basic regulation of our genes. The new example -- a gene on the X chromosome called UTX -- is ... > full story -
Roles Of DNA Packaging Protein Revealed
February 12, 2009 — Scientists have found that a class of chromatin proteins is crucial for maintaining the structure and function of chromosomes and the normal development of eukaryotic ... > full story -
How 'Companion' Cells To Sperm Protect Them From Genetic Damage
February 5, 2009 — In plant pollen grains, sperm cells, which carry the genetic material to be passed on to progeny, are cocooned within larger "companion" cells that provide sperm with energy and nourishment. A team ... > full story -
Possible Drug Target For Obesity Treatment A 'No-Brainer'
February 4, 2009 — Scientists have discovered a gene that when mutated causes obesity by dampening the body's ability to burn energy while leaving appetite ... > full story -
Rethinking The Genetic Theory Of Inheritance: Heritability May Not Be Limited To DNA
January 18, 2009 — In the first study of its kind, scientists have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account ... > full story -
Growth Of New Brain Cells Requires 'Epigenetic' Switch
January 8, 2009 — New cells are born every day in the brain's hippocampus, but what controls this birth has remained a mystery. Neuroscientists have now discovered that the birth of new cells, which depends on brain ... > full story
