During dietary fat absorption, the gut packages the majority of the fats into lipid particles that are secreted into blood circulation. The gut is also capable of storing a considerable amount of fats that can be released at a later time upon receiving certain stimulus signals. One of the signals is glucose ingestion. This protocol examines how glucose ingestion releases gut lipid store. Participants drink a fatty formula and 5-9 hours later drink either a glucose solution or water (as control). One hour later, duodenal biopsy specimen are taken for analysis of lipid stores in the gut cells.
Participants undergoing upper gastrointestinal endoscopy and duodenal biopsy for clinical indications are recruited after obtaining informed consent. They first have a high fat liquid formula. 5 to 9 hours later, half of the participants drink 50 grams of glucose in 50 ml of water. The other half drink 50 ml of water. 1 hour later, duodenal biopsy specimen are collected and stored for analysis of lipid stores in the gut using electron microscopy and proteins using proteomics.
