The purpose of this study is to evaluate the effect of zinc supplementation on insulin secretion by genotype of SLC30A8.
As diabetes increases at an alarming rate, strategies for prevention of this disease must be developed. For a given individual, there are both biologic (e.g., genetic) and environmental (e.g., lifestyle) factors that comprise her individual risk of diabetes. Researchers can take advantage the accumulating knowledge of these individual factors to design individualized strategies for diabetes risk assessment and prevention. For example, a mutation in a particular gene, SLC30A8, which encodes a zinc transporter, has been shown to increase the risk of diabetes probably through impairment of insulin secretion. In the proposed research project, the investigators aim to conduct a pilot study to see the effect of zinc supplementation on insulin secretion in people with and without this genetic mutation to see if zinc can improve insulin secretion in those with the mutation. The results from this study will help the investigators to plan a larger, more definitive study to determine if zinc supplementation can be used to prevent or treat diabetes in those with this mutation in SLC30A8.

Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
An enzyme that catalyzes the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. EC 188.8.131.52.
An arylsulfatase that catalyzes the hydrolysis of the 4-sulfate groups of the N-acetyl-D-galactosamine 4-sulfate units of chondroitin sulfate and dermatan sulfate. A deficiency of this enzyme is responsible for the inherited lysosomal disease, Maroteaux-Lamy syndrome (MUCOPOLYSACCHARIDOSIS VI). EC 184.108.40.206.
An enzyme that specifically cleaves the ester sulfate of iduronic acid. Its deficiency has been demonstrated in Hunter's syndrome, which is characterized by an excess of dermatan sulfate and heparan sulfate. EC 220.127.116.11.
