Project description:Affymetrix single nucleotide polymorphism (SNP) array data were collected to study genome-wide patterns of genomic variation across a broad geographical range of Island Southeast Asian populations. This region has experienced an extremely complex admixture history. Initially settled ~50,000 years ago, Island Southeast Asia has since been the recipient of multiple waves of population movements, most recently by Austronesian-speaking groups ultimately from Neolithic mainland Asia and later arrivals during the historic era from India and the Middle East. We have genotyped SNPs in ~500 individuals from 30 populations spanning this entire geographical region, from communities close to mainland Asia through to New Guinea. Particular attention has been paid to genomic data that are informative for population history, including the role of recent arrivals during the historic era and admixture with archaic hominins.
Project description:The objective of the study was to characterize distinct endotypes of asthma related to damp and moldy buildings and to evaluate the potential molecular similarities with idiopathic environmental intolerance (IEI). The nasal biopsy transcriptome of 88 study subjects was profiled using samples obtained at baseline.
Project description:Pseudomonas aeruginosa is a common bacterium in the terminal plumbing system of buildings and it is from this niche that a substantial fraction of infections are acquired. To better understand P. aeruginosa biology in this environment, we examined the transcriptomes in tap water and pond water.
Project description:The objective of the study was to characterize distinct endotypes of asthma related to damp and moldy buildings and to evaluate the potential molecular similarities with idiopathic environmental intolerance (IEI). The blood cell transcriptome of 88 study subjects was profiled using peripheral blood mononuclear cell (PBMC) samples obtained at baseline.
