Project description:The aim for this study was to compare the differences in the methylome of three Russian wheat aphid populations that differ in virulence and bacterial load. Differences in the methylome of US Russian wheat aphid biotype 2 (US-RWA2) that have undergone removal of their phytobiomes through isolation of newly born nymphs from their mothers compared to nymphs who stayed in close proximity to their progenitors. US-RWA1 is the least virulent biotype and US-RWA2 is the most virulent biotype. The isolated US-RWA2 population (with a reduced bacterial load) has been shown to be less virulent than the co-fed population (Luna et al., 2018). The corresponding two methylomes were then compared to the methylome of US Russian wheat aphid biotype 1 (US-RWA1 is less virulent than US-RWA2) to ascertain the contribution (or lack thereof) of the phytobiome in regards to the increased/decreased virulence of phytobiome present and absent aphids. We investigated the overall, genic, intergenic, exonic and intronic methylation - as well as genic and intergenic hemimethylation -all three available contexts ( CpG, CHG and CHH) through use of the Bismark pipeline. These findings were used to ascertain to what effect the phytobiome (bacterial load) had on methylation within the US Russian wheat aphid biotypes.
Project description:Purpose: We studied dioxin exposures and DNA methylation in sperm in 37 men from the Air Force Health Study Methods: We compared methylation levels in subjects with no, low, medium, and high dioxin levels using EWAS and looking at regions of DNA. We compared our results to those from a Russian study Results: No loci were found to be significantly associated with dioxin exposure in the EWAS when controlling for false discovery rate. Region H19 was found to have significant associations. Five of our loci of interest overlapped with significant findings from the Russian study
