Protein commonly screened for in pregnancy is linked to gestational diabetes

Laboratory research and analysis of epidemiological data by Silvia Corvera, MD, and Tiffany Moore Simas, MD, MPH, MEd, and colleagues show that low levels of a protein commonly seen in screening tests for chromosomal disorders during the first trimester of pregnancy is associated with adipose tissue remodeling, glucose resistance and gestational diabetes mellitus in pregnant women. The study, published in Science Translational Medicine, outlines a new role for pregnancy-associated plasma protein A, known as PAPPA, in gestational diabetes, with translational potential as both a diagnostic tool and therapeutic target.
