Fredrick Rosario is Assistant Professor in the Division of Reproductive Sciences, Department of Obstetrics and Gynecology, at the University of Colorado Anschutz Medical Campus. His research asks how mTOR signalling in the placenta controls the supply of amino acids and folate to the growing fetus.
In the Atlas he is senior author of SHIMADA2026. In 46 full-term human placentas, those from boys had higher mTORC1 signalling, faster amino acid transport by System A and higher mitochondrial capacity than those from girls.
