The Effects of Mannose Supplementation on Glycosylation and Protein Levels in Human Sera

Not Applicable

Conditions

Interventions
Dietary Supplement: Mannose
Registration Number
NCT06507735
Lead Sponsor
University of Texas Southwestern Medical Center
Brief Summary

The purpose of our study is to investigate the effects of supplemental mannose on sera of humans who are healthy. We will perform proteomics studies to elucidate changes to glycan structure and protein level changes. We hypothesize that we may find that mannose supplies more properly glycosylated protein substrate and helps expedite protein synthesis, that excess mannose leads to alternative glycan structures which confer improved stability, or that there are new sites that become glycosylated after mannose supplementation.

Detailed Description

Subjects will be enrolled and a baseline blood sample taken. Subjects will take mannose supplements for 1 week (3-4 packets of a standard dose in water), then a follow up blood sample will be taken.

Subject blood will be analyzed by proteomic analysis for 1) change in glycan structure or 2) other protein based approaches to measure changes in levels of proteins.
