Study TitleFetal metabolomic signature of exposure to iAs during pregnancy
Study TypeMetabolomics
Study SummaryThis metabolomics pilot study was aimed to identify a fetal metabolomic signature of exposure to iAs during pregnancy. Fetal cord blood serum was collected immediately after delivery from a saline cleaned umbilical cord using an anticoagulant-free vacutainer tube, after clot formation the tube was centrifuged at 1200 rpm and the serum was collected and stored at -70°C. A subset of 50 cord serum samples were selected from the larger BEAR cohort to represent a wide range of iAs exposure as determined by iAs in drinking water (DW-iAs). The exposure during pregnancy was confirmed using U-tAs. A total of 50 cord blood serum samples were used in the metabolomics analysis The samples included 25 newborns with lower maternal iAs exposure levels (DW < 25?g As/L, mean U-tAs=16 ?g/L) and 25 newborns with higher maternal iAs exposure levels (DW> 25?g As/L, mean U-tAs =107 ?g/L).
