Is peak stimulated insulin secretion associated with specific changes in gene expression profiles in sporadic insulinomas?
We show that genes that are relevant to the pathogenesis of hyperinsulinemia are expressed preferentially in insulinomas. In addition, patients with a distinct and common pattern of gene expression had significantly higher stimulated insulin secretion levels. The study of these genes may help to identify the biochemical pathways that are responsible for pathologic insulin secretion.
Several studies have shown an indirect relationship between polyethylene thickness and its wear. Berry et al. reported catastrophic failure in hip prostheses with a polyethylene thickness of less than 5 mm; in our study, the three failed polyethylene liners were 5.9 mm in thickness.
