Plasma serpinB1 is related to insulin sensitivity but not pancreatic β-Cell function in non-diabetic adults.

ABSTRACT: Pancreatic β-cell dysfunction because of reduced β-cell mass and function is a primary determinant in the progression of diabetes. Increase in β-cell mass and compensatory hyperinsulinaemia is frequently associated with insulin-resistant states. Although the humoral factors mediating this compensatory response are unknown, serpinB1, a protease inhibitor, has recently been proposed to be one such factor. In this study, we examine the relationships between plasma serpinB1, insulin sensitivity, and pancreatic β-cell function in non-diabetic individuals. 117 subjects (women, n = 50, men, n = 67; age= 37.6 ± 10.8; BMI=31.1 ± 7.7 kg/m2) underwent an insulin-modified frequently sampled intravenous glucose tolerance test (FSIVGTT) at the NIH Clinical Research Center.
