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.
A new study that looks at how lactose intolerance develops over time may give new insight into understanding how mental health issues develop.
Mouse study reveals the sperm of males infected with Toxoplasma carries an altered epigenetic signature that impacts the brain of the offspring. While the effects of T. gondii infections in pregnant women are fairly well documented, this is a novel study looking at the impact of male infection and its impact on offspring. The study raises the question as to whether T. gondii infections in men before conception impact the health and development of future generations.
A new study reports Holocaust survivors who suffer from PTSD and their adult children age less successfully and display more unhealthy behaviors than those with no PTSD or who did not experience the horrors of the Holocaust.
A new study reports people with more Alzheimer's related neuropathology in their brains had higher levels of DNA modifications within the ANK1 gene.
Teenage binge drinking is linked to altered gene expression in the brain, specifically the central nucleus of the amygdala. Adolescent rats exposed to alcohol had increased levels of miR-137, resulting in lower expression of proteins essential for healthy neuron growth. During adulthood, these rats displayed higher levels of anxiety and an increased preference for alcohol consumption.
Researchers conduct the first study to use nonharmful stress, like intermittent systemic hypoxia, to protect against disease in the first generation offspring in mice.
POMC, a gene which regulates the stress response system, and PER2, a gene associated with circadian regulation, are altered in women who drank moderate-to-high amounts of alcohol during pregnancy and their newborns.
