| Title: Differential expression of various isoforms of superoxide dismutase in the cells of the human exocrine pancreas | ||
| Author: Marko VRZGULA, Jozef MIHALIK, Juraj TESLIK, Ingrid HODOROVA | ||
| Abstract: OBJECTIVES: Superoxide dismutase (SOD) is an enzyme that plays a crucial role in protecting cells from oxidative damage. Our study aims to address the lack of papers simultaneously analyzing the immunoreactivity of all three distinct isoforms of SOD in human exocrine pancreas cells. BACKGROUND: Superoxide dismutases (SODs) facilitate the conversion of superoxide radicals into less harmful substances. By neutralizing superoxide radicals, SODs help prevent the formation of highly reactive and destructive species that can adversely affect manifold cellular components. METHODS: The study analyzed immunoreactivity of SODs in samples of six healthy adult human pancreases, while using the indirect immunohistochemical method under a light microscope. RESULTS: SOD1 was predominantly found in centroacinar cells and epithelial cells of the duct system while SOD2 was mainly detected in the epithelial cells of interlobular ducts. Both enzymes were prominently present in the basal region of acinar cells near the cell nucleus. The expression of SOD3 was observed to be rare. CONCLUSION: Understanding the intracellular metabolism of SODs in healthy exocrine pancreas cells serves as a basis for determining the precise role of oxidative damage and SOD signaling in the pathogenesis of various pancreatic diseases, including chronic pancreatitis and pancreatic cancer (Fig. 6, Ref. 24).
