About

The Precision Nutrition Core provides expertise and services in two areas: 1) Nutrigenomics and 2) Microbiome Analysis. The Core offers laboratory services as well as customized, cutting-edge research tools, including 1) whole genome, exome, and targeted gene sequencing; 2) RNA-sequencing; 3) microbiota characterization, including 16S rRNA gene sequencing and shotgun metagenomics; 4) targeted genotyping using PCR-based assays; 5) array-based gene expression profiling; 6) and bisulfide sequencing for methylation patterns in humans and mouse models. The Core provides investigators with the expertise and resources necessary to investigate the role of host genetic and gut microbiome factors in biological responses to nutritional exposure. The mission of the Core is to provide a suite of precision nutrition services that enable investigators to integrate nutrigenomics and microbiome analysis into nutrition and obesity research to advance our understanding of how individual genetics and gut microbial communities influence individual variability related to nutritional exposures and adiposity.

The Precision Nutrition Core also facilitates nutrition/obesity research through the UNC Microbiome Core Facility, and facilitates collaborations with the Gnotobiotic Core, the High-Throughput Sequencing Facility, and the Mammalian Genotyping Core at UNC.
