Creating a West African BioResource for Nutritional Genetics and Epigenetics

点击翻译按钮获取中文摘要

The Nutrition Theme at MRC Unit The Gambia will partner with a broad team of collaborators in Bristol (Bristol University and MRC Integrative Epidemiology Unit) to create a new West African BioResource (WABR). The new bioresource will consist of rich nutritional cohorts, databases and the Keneba Biobank constructed over decades of research in the West Kiang area of rural Gambia. These will be made open access to worldwide collaborators to support novel research methods to better understand the complex relationships between diet, nutritional status and infectious and non-communicable diseases. The new methodologies will be strongly based on a genes-in-action (alternatively known as recall-by-genotype) paradigm that allows investigators to research the impact of genetic and epigenetic variants on health with highly efficient studies using small numbers of participants. Based upon the Bristol group's world-leading processes we will conduct a 'clone and adapt' exercise to bring the Gambian bioresource up to the same world standard. This process will be extended to the biobanks at MRCG Fajara and at our West African Global Health Alliance (WAGHA) partner institute IRESSEF in Dakar. We will also prepare a bioresource toolkit that can be accessed by other institutes with cohorts and biobanks in other LMICs.
