Fetal alcohol spectrum disorder (FASD) affects the hippocampal levels of histone variant H2A.Z-2.

Fetal alcohol spectrum disorder (FASD) is caused by prenatal exposure to ethanol and has been linked to neurodevelopmental impairments. Alcohol has the potential to alter some of the epigenetic components that play a critical role during development. Previous studies have provided evidence that prenatal exposure to ethanol results in abnormal epigenetic patterns (i.

Trichostatin A decreases the levels of MeCP2 expression and phosphorylation and increases its chromatin binding affinity.

MeCP2 binds to methylated DNA in a chromatin context and has an important role in cancer and brain development and function. Histone deacetylase (HDAC) inhibitors are currently being used to palliate many cancer and neurological disorders. Yet, the molecular mechanisms involved are not well known for the most part and, in particular, the relationship between histone acetylation and MeCP2 is not well understood.
