Summary

The main goal of this project is to determine whether mitochondrial function in circulating cells is related to that measured in the muscle fibers of the same subjects.

Detailed description

Data from human and animal models strongly suggests that reduced tissue mitochondrial function can be an early marker for detection of dysfunctional metabolism. It is unclear if tissue mitochondrial dysfunction can be detected using less invasive methodology. In this project, the investigators plan to study mitochondrial bioenergetics in circulating cells and paired muscle biopsies in two metabolic disparate groups of women; healthy lean vs. overweight/obese with/without insulin resistant women of similar age. Women of similar age that are either healthy lean or overweight/obese with/without insulin resistance will be recruited to participate in one study that includes a blood draw and a muscle biopsy. Mitochondrial function in circulating blood cells and muscle tissue will be determined. The association between circulating blood cells and muscle tissue mitochondria respiration will be determined for the two groups combined, and differences between groups will also be investigated.
