ABSTRACT: : Maternal consumption of artificially sweetened beverages during pregnancy is associated with infant gut microbiota modifications and increased infant body mass index
Project description:We aimed to determine if maternal consumption of artificially sweetened beverages (ASB) during pregnancy is associated with modifications of infant gut bacterial community composition and development during the first year of life, and whether these alterations are linked with infant body mass index (BMI) at one year of age.

Project description:The objective of this study was to analyze genome-wide differential methylation patterns in maternal leukocyte DNA in early pregnant and non-pregnant states. This is an age- and body mass index-matched case-control study comparing the methylation patterns of 27,578 cytosine-guanine (CpG) sites in 14,495 genes in maternal leukocyte DNA in early pregnancy (n=14), in the same women postpartum (n=14), and in nulligravid women (n=14) on a BeadChip platform. Transient widespread hypomethylation was found in early pregnancy as compared with the non-pregnant states. Methylation of nine genes was significantly different in early pregnancy compared to both postpartum and nulligravid states (< 10% False Discovery Rate). Early pregnancy may be characterized by widespread hypomethylation compared to non-pregnant states; there is no apparent permanent methylation imprint after a normal-term gestation. Nine potential candidate genes were identified as differentially methylated in early pregnancy and may play a role in the maternal adaptation to pregnancy. This is an age- and body mass index-matched case-control study comparing the methylation patterns of 27,578 cytosine-guanine (CpG) sites in 14,495 genes in maternal leukocyte DNA in early pregnancy (n=14), in the same women postpartum (n=14), and in nulligravid women (n=14) on a BeadChip platform.
Project description:We combined genome-wide DNA methylation profiling of buccal cells from 47 full-term one-week old infants with accurate measurements of infant fat mass and fat-free mass using air-displacement plethysmography and found no significant a between DNA methylation and infant body composition
Project description:Comparison of transcript abundance estimates and bioinformatic inferences derived from DBS vs PAXgene vs peripheral blood mononuclear cell (PBMC) samples. Gene expression profiling was conducted using parallel collection and assay of venipuncture samples (PAXgene and PBMC) and DBS samples. Data come from 83 community dwelling adults recruited from the Chicago metropolitan area. In addition to basic demographic characteristics (age, sex, race/ethnicity), participants were also assessed on health-related characteristics (body mass index/BMI; history of smoking or heavy alchol consumption), and educational attainment (z-score transformed). Categorial variables were coded 0=no/absent and 1=yes/present.
