Further, although several previous studies have evaluated GSH levels in various extracellular compartments, including bronchoalveolar lavage (BAL) fluid, these studies generally focused on alterations in GSH:GSSG balance in association with disease, or the consumption of GSH during prostaglandin or leukotriene synthesis, with more modest phenotypic, pathophysiologic, or mechanistic information (4, 5)
whereas GIP enhances insulin secretion and affects fat metabolism and -cell proliferation (72, 73)
