In a recent study, scientists have discovered a new environmental hazard that can affect epigenetics in cells. Epigenetics is the study of chemical modifications to DNA that can change the way genes are expressed without changing the underlying DNA sequence. The environmental hazard in question is a by-product of the manufacturing of polymers, called polypropylenedinitrile (PPND). It’s been found that PPND can cause epigenetic changes to cells. This means that even if a person is exposed to low levels of PPND, their cells could be affected by it. This could lead to changes in gene expression and potentially the development of diseases and illnesses. It’s important that we continue to research the effects of manufacturing by-products such as PPND on our health, and that this information is made readily available to the public.
