Children are a blend of both their parent’s genes, but not necessarily in an equal way. Some genes inherited from either the father or mother are epigenetically marked with information that causes them to be inactive. This phenomenon is known as genomic imprinting and, although normal, could lead to disease if combined with mutations. For the most part, we acquire two working copies of each gene – one from our dad and one from our mom. Although in genomic imprinting, [more…]

You might be familiar with the popular epigenetic study that suggests when mother rats lick their pups, they leave epigenetic marks on their babies’ DNA. This, in turn, helps them grow up to be calm adults. On the other hand, pups who receive very little licking, grooming, or nursing from their moms tend to grow up more anxious. It wasn’t their genes that dictated their stressed-out behavior, but their epigenome, which was shaped by the nurturing behavior of their mother [more…]

The way a baby is delivered may epigenetically impact stem cells of the infant, according to a new study at Karolinska Institutet. Their findings could help scientists understand the differences between various modes of delivery, for example, why babies delivered via cesarean section are statistically more susceptible to immunological diseases. It’s still uncertain whether this epigenetic mechanism is long-term or temporary. Women are now more than ever electing to give birth by cesarean section, the most popular surgical procedure in [more…]
