Abstract

Background: Considering the significant participation of the microenvironment in the local aggressiveness of odontogenic keratocysts, this study aims to evaluate the expression of ADAMTS-1 and its substrates, versican, aggrecan and brevican in this locally invasive odontogenic cyst.

Methods: Immunohistochemistry and polymerase chain reaction (PCR) were conducted on 30 cases of odontogenic keratocysts (OKCs) and 20 dental follicles (DFs).

Results: The immunohistochemical expression of these proteins was predominantly cytoplasmic and granular across all samples. In epithelial tissue, the immunoexpression of aggrecan and versican was higher in OKC (p < 0.05) compared to DF. Comparing the expression of proteins between the OKC epithelium and the cystic capsule, it was observed that all molecules were more expressed in the epithelium (p < 0.001). RT-PCR confirmed the expression of ADAMTS-1 and proteoglycans in all samples.

Conclusion: ADAMTS-1, aggrecan, brevican, and versican were expressed in all samples with a granular and cytoplasmic pattern. RT-PCR confirmed their presence in both OKC and DF, but only aggrecan and versican exhibited significantly higher levels in OKC (p < 0.05). Protein expression was notably greater in the epithelial component of OKC. These findings underscore the potential role of these proteins in the biological behavior of OKC.

期刊介绍： Diagnostic Pathology is an open access, peer-reviewed, online journal that considers research in surgical and clinical pathology, immunology, and biology, with a special focus on cutting-edge approaches in diagnostic pathology and tissue-based therapy. The journal covers all aspects of surgical pathology, including classic diagnostic pathology, prognosis-related diagnosis (tumor stages, prognosis markers, such as MIB-percentage, hormone receptors, etc.), and therapy-related findings. The journal also focuses on the technological aspects of pathology, including molecular biology techniques, morphometry aspects (stereology, DNA analysis, syntactic structure analysis), communication aspects (telecommunication, virtual microscopy, virtual pathology institutions, etc.), and electronic education and quality assurance (for example interactive publication, on-line references with automated updating, etc.).
