Pregnancy changes how hundreds of genes work in a woman's body

It’s no secret that women’s bodies go through radical changes during pregnancy, but we’re finally starting to understand what happens at the gene level.

Alicia Smith at Emory University in the US and her colleagues took blood samples from 63 women early and late in pregnancy to see if they could detect any changes in their gene expression.

Of the 16,000 genes they looked at, they found that 439 altered their activity between the first and third trimester of pregnancy.

Dr. Smith is a faculty member in the GMB program.
