what is Lifelines DAG3?
There is increasing insight into the role of bacterial composition in the intestine and upon the occurrence of (chronic) diseases. Previous research in Lifelines DEEP demonstrated the relation of the microbiome and lipids, but also many other diseases and intrinsic and extrinsic factors.
The purpose of DAG3 is to gather additional data and biological samples from Lifelines participants to answer research questions such as: ‘What is the role of the microbiome in the occurrence of chronic diseases?’, and ‘What is the relation between genetic variants, methylation, gene expression and metabolite levels?’ Of course more research questions can be answered based on the materials collected in DAG3, which are available for researchers worldwide.
Previously we collected additional biological samples in 1500 Lifelines participants to allow analysis of the microbiome, (epi)genome, transcriptome, metabolome and other biological levels. This sub-cohort Lifelines DEEP allows for new insights into disease mechanisms and future potential therapeutic prevention methods.
In DAG3 we scaled up the number of participants as well asthe the number of microbiome sample sites. We have collected these extra biological samples in 10,000 Lifelines participants
The (molecular) data that will be generated based on the DAG3 materials (hundreds of thousands of phenotypes) will be deposited in the Lifelines database and will be available for researchers worldwide.
The study was initiated by the department of Genetics of the Universty Medical Center Groningen.
