Development of Human mRNA as a Biomarker for Environmental Enteropathy

Mark Manary of Washington University in the U.S. and colleagues will develop a strategy for the non-invasive diagnosis of environmental enteropathy, which causes malnutrition and growth failure in young children in the developing world. They will devise a robust protocol to isolate human RNA of the small bowel from samples of stool, and will test a broad panel of candidate biomarkers for their ability to identify environmental enteropathy with high sensitivity using samples from at risk Malawian children. These tools will be critical for studying disease etiology and for the development of effective intervention strategies.
