Fathers’ Alcohol Consumption Influences Sons’

Köp billig Atarax online utan recept “We examined whether a father’s exposure to alcohol could alter expression of the genes he passed down to his children,” said senior investigator Gregg E. Homanics, PhD, professor of anesthesiology and pharmacology at the Pittsburg School of Medicine. “Rather than mutation of the genetic sequence, environmental factors might lead to changes that modify the activity of a gene, which is called epigenetics. Our mouse study shows that it is possible for alcohol to modify the dad’s otherwise normal genes and influence consumption in his sons, but surprisingly not his daughters.”1

أفضل الخيارات الثنائية “We suspected that the offspring of alcohol exposed sires would have an enhanced taste for alcohol, which seems to be the pattern for humans,” said Finegersh. “Whether the unexpected reduction in alcohol drinking that was observed is due to differences between species or the specific drinking model that was tested is unclear.”1
