Summary. The present work was aimed on the study of patterns of human beta-defensin-2 (hBD-2) expression in human gastric tumors. Materials and methods: 17 samples of surgically resected human gastric adenocarcinoma paired with respective normal tissue controls have been analyzed for the expression of hBD-2 by semi-quantitative RT-PCR and by immunohistochemical analysis using anti-hBD-2 monoclonal antibodies (mAbs) generated against recombinant hBD-2 by standard hybridoma technology. Results: The hyperexpression of hBD-2 on mRNA and protein levels was registered in 6 from 17 gastric tumor samples compared to respective controls; however, hBD-2 expression patterns seems not be related to the differentiation grade and stage of tumors and the presence of anti-Helicobacter pylori-antibodies in the blood serum of the patients. Conclusion: In human gastric adenocarcinomas expression of hBDs possesses heterogeneic character; the research on larger cohort of the patients with gastric cancer should be further performed.
