Dr. Wilfried Karmaus, professor in the division of epidemiology, biostatistics, and environmental health at the University of Memphis School of Public Health, has been awarded an R01 grant by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health. This grant aims to firstly study whether and which metabolites, nutrients, and toxins in maternal serum during pregnancy are associated with methylation at positions in the genomic DNA where a cytosine is located next to a guanine, a cytosine-phosphate-guanine (CpG) site in blood spot collected after delivery. Secondly, to test whether the methylation of these CpG sites are associated with lung growth in children, adolescents, and adults. Drs. Wilfried Karmaus, Hongmei Zhang, and Su Chen at the University of Memphis collaborate with Michigan State University, the Ilse of Wight Asthma and Allergy Centre, the University of Southampton and the University of Bristol in the United Kingdom, and the Hokkaido University in Japan.
