Researchers report on the epigenetic effect of early life stress. In a new study, researchers reveal mice who experienced stress in the first few weeks of life showed deterioration in memory, learning and maternal behaviors. Behavioral changes were seen in their later offspring, regardless of sex.
A new study reports children who are subjected violence early in life experience faster biological aging, including earlier onset of puberty and epigenetic aging, than peers who are not abused. Additionally, children exposed to other early life adversities, such as poverty and food insecurity, show delayed signs of pubertal development.
Researchers report when mice bred to display Alzheimer's like symptoms were given diets high in choline, their offspring showed improvements in spatial memory compared to those exposed to normal levels of choline in the womb.
Chronic cocaine use alters the epigenetic profile of the FosB gene in the hippocampus. These alterations are required for cocaine-dependent gene expression and cocaine environment associations. Modification of hippocampal FosB results in a condition critical for cocaine-related learning.
Aspartame, a sweetener found in diet drinks and food, has been linked to an increased risk of developing anxiety behaviors in a new mouse study. The effects of exposure to aspartame extended for up to two generations.
Study reveals how acetate, a byproduct of alcohol breakdown, travels to the brain's learning system and alters proteins that regulate DNA function.
New technology can rapidly halt or start the expression of genes by shining a light on the cells.
Researchers have shown stress on preadolesecent and adult male mice induced an epigenetic mark in their sperm which reprogrammed their offspring's HPA axis, a region the the brain which governs stress response.
Researchers report a father's exposure to nicotine may have lasting effects on the cognitive development of his offspring. The study reports nicotine exposure may cause epigenetic alterations in key genes within the father's sperm, affecting not only his direct children but also grandchildren.
Researchers reveal the role PRC2 plays in Huntington's disease and other neurodegenerative diseases.
Using a combination of neuroimaging, genetic research, epigenetics and other biological data in conjunction with artificial intelligence may result in a biological classification of mental illness, rather than diagnosing people based on symptoms alone.
According to researchers, dietary restrictions can lead to alterations in lipid metabolism, which helps to increase lifespan in mice.
