PBDEs, common flame retardants found on household furniture, caused an increased risk of diabetes in mice only exposed to the chemicals through their mother's milk. In addition to increased glucose intolerance, researchers also noted higher levels of endocannabinoid in the livers of the offspring of mice exposed to PBDEs.
New research could help explain how some cases of ASD can result from environmental influences rather than genetic mutations.
A new study reports symptoms of psychiatric disorders, such as anxiety and heightened response to stress, may be transmitted from mom to child, and even grandchildren by multiple non genetic mechanisms.
A new study reports increased risk of schizophrenia in mice whose mothers were deprived of DHA during pregnancy.
A new study report heartbeat irregularities connected with abnormalities in brain activity may be a biomarker for epilepsy in those who have suffered brain injury or infection.
Researchers used epigenetic modulators to reduce the damage done by stress to neuroplasticity. Findings reveal acute intervention in epigenetic mechanisms produced antidepressant effects more rapidly than conventional medications.
Marijuana use alters a gene associated with autism in sperm. Hypomethylation was identified in the DLGAP2 gene in the sperm of male rats exposed to THC. The hypomethylated state was also detected in the forebrains of their offspring. Further research is needed to establish if there is a definitive link between paternal cannabis use and ASD in humans.
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.
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.
