Zusammenfassung
Background. Insulin-degrading enzyme (IDE, insulysin, insulinase; EC 3.4.22.11), a thiol metalloendopeptidase, is involved in intracellular degradation of insulin, thereby inhibiting its translocation and accumulation to the nucleus. Recently, protein expression of IDE has been demonstrated for the first time in the epithelial ducts of normal breast and in breast cancer tissue (Radulescu et al., Int J Oncol 30: 73; 2007). Materials and Methods. Utilizing four different antibodies generated against different epitopes of the IDE molecule, we performed western blot analysis and immunohistochemical staining on sever…
