Expression data from mothers, placentas, and newborns in the Democratic Republic of Congo

Project description:Maternal stress has long been associated with lower birthweight but mechanisms remain elusive. This study explored how maternal stress may impact changes in gene expression within a cohort of mother-placenta-newborn triads in the eastern Democratic Republic of Congo We used microarrays to detail the global programme of gene expression underlying the impact of maternal stress on newborn birthweight and identified that global placental gene expression may partially mediate the negative impact of maternal war stress on newborn birthweight.

Longitudinal analysis of birthweight and epigenetic aging among children from birth to age three in the Democratic Republic of Congo

Project description:Genome-wide DNA methylation profiling of venous blood samples from children in the Eastern Democratic Republic of Congo from birth to age three. DNA methylation data were noob normalized and uploaded to Steve Horvath's epigenetic age calculator website to calculate Horvath epigenetic age acceleration for each participant at each timepoint for which they had data available. Replicates were averaged and a single outlier at birth was removed as described in the manuscript, leaving 155 observations from 67 unique individuals. Sample size at each timepoint was as follows: n = 64 at birth, n = 8 at six months, n= 35 at one year, n = 32 at two years, and n = 16 at three years.

Epigenetic analysis of psychosocial stress among mother-newborn dyads in the Democratic Republic of Congo (EAA)

Project description:Prenatal maternal stress has a negative impact on child health but the mechanisms through which maternal stress affects child health are unclear. Epigenetic variation, such as DNA methylation, is a likely mechanistic candidate as DNA methylation is sensitive to environmental insults and can regulate long-term changes in gene expression. We recruited mother-newborn dyads in the Democratic Republic of Congo to investigate the effects of maternal stress on DNA methylation in mothers and newborns. We used four measures of maternal stress to capture a range of stressful experiences: general trauma, sexual trauma, war trauma, and chronic stress. We identified differentially methylated positions (DMPs) associated with general trauma, sexual trauma, and war trauma in both mothers and newborns. No DMPs were associated with chronic stress. Sexual trauma was positively associated with epigenetic age acceleration across several epigenetic clocks in mothers. General trauma and war trauma were positively associated with newborn epigenetic age acceleration using the extrinsic epigenetic age clock. We tested the top DMPs for enrichment of DNase I hypersensitive sites (DHS) and found no enrichment in mothers. In newborns, top DMPs associated with war trauma were enriched for DHS in embryonic and fetal cell types. Finally, one of the top DMPs associated with war trauma in newborns also predicted birthweight, completing the cycle from maternal stress to DNA methylation to newborn health outcome. Our results indicate that maternal stress is associated with site-specific changes in DNAm and epigenetic age acceleration in both mothers and newborns.

Analysis of ToxT regulon in Vibrio cholerae El Tor

Project description:Using a combination of ChIP-seq and RNA-seq we show that ToxT regulates expression of the small RNA TarB. TarB modulates the expression level of the transcriptioanl repressor VC0177. VC0177 controls expression of several genes including VC0179. The function of the Vibrio 7th pandemic island-1 (VSP-1) in cholera pathogenesis has remained obscure. Utilizing ChIP-seq and RNA-seq to map the regulon of the master virulence regulator ToxT, we identify a TCP island encoded small RNA that reduces the expression of a previously unrecognized VSP-1 encoded transcription factor termed VspR. VspR modulates the expression of several VSP-1 genes including one that encodes a novel class of di-nucleotide cyclase (DncV), which preferentially synthesizes a previously undescribed hybrid cyclic AMP-GMP molecule. We show that DncV is required for efficient intestinal colonization and down-regulates V. cholerae chemotaxis, a phenotype previously associated with hyperinfectivity. This pathway couples the actions of previously disparate genomic islands, defines VSP-1 as a pathogenicity island in V. cholerae and implicates its occurrence in 7th pandemic strains as a benefit for host adaptation through the production of a regulatory cyclic di-nucleotide.
