Pollution and epigenetics: can our experiences affect the health of our children?
Keywords:
epigenetics, pollution, transgenerational, inheritance, geneticsAbstract
Our gene expression is regulated by chemical tags attached to DNA which indicates when genes should be switched on or off. Any alterations in the pattern of these chemical tags, especially during early life stages, such as pregnancy or neonatal life, can affect gene expression immediately or even decades later. Our experiences such as lifestyle, diet and pollution can modify the pattern of chemical marks and the most worrying thing is that the harmful effects can inherit across generations, according to some studies. Thus, it would be precise to wonder ourselves whether our experiences such as the food we eat, the kind of life style we have and the environment where we live will affect the health of our children.
