The first direct evidence has been found linking smoking to epigenetic changes in genes that help fight cancer. Reversing these changes may one day provide a new route to treating cancer.
Women with cervical cancer are known to have higher levels of epigenetic modifications – methyl groups attached to particular sites on their DNA – affecting a gene called p16, which is known to be involved in suppressing tumours.
@oristarA,
Punkey is not a good source for ESL, Oristar. In this case, the epigenetic modifcations are the methyl groups themselves which are found on certain genes. The methyl groups modify the gene p16.

You're hardly in a position to be making those decisions, Setanta. You have certainly advanced more than your share of absolute nonsense over the years.
