The CNRGH contributed to a work showing that tobacco exposure, even when stopped before becoming pregnant, leaves traces in the placenta in the form of epigenetic modifications to its DNA. The study, headed by Inserm, the CNRS and Grenoble Alpes University, was published in BMC Medicine. Any possible effects of these modifications on the development of the fetus or the health of the child remain to be determined.
