“High-resolution metabolomics of exposure to tobacco smoke during pregnancy and adverse birth outcomes in the Atlanta African American maternal-child cohort”

HERCULES investigators Drs. Dana Barr, Barry Ryan, Audrey Gaskins, Jeremy Sarnat, Carmen Marsit, and Donghai Liang recently published a paper in Environmental Pollution on high-resolution metabolomics of exposure to tobacco smoke during pregnancy and adverse birth outcomes in the Atlanta African American maternal-child cohort. This study reveals perturbation in urea cycle and amino metabolism associated with cotinine may contribute to shorter gestation.
