Abstract
Background Chewing areca nuts can result in an oral disorder known as oral submucous fibrosis (OSF), which has the potential to be cancerous. Although it is only beginning to spread to European and the North American continents, it is highly prevalent in Southeast Asia. The probability of malignant transformation from OSF is raised by chewing tobacco use. In the current research, our objective was to assess the potential anti-fibrosis effects and the ability to prevent malignant transformation through the application of mangosteen pericarp extract. Methodology The Ethical Approval-IHEC/SDC/OMED-2101/23/085 from the institution was obtained to conduct this ex vivo study. The cytotoxicity effect of mangosteen pericarp extract on both normal and fibrotic buccal mucosal fibroblasts originating from OSF tissues was tested. Cell proliferation and cell migration by scratch wound healing assay was examined. Dual staining was done to determine the mode of cell death. Additionally, real-time PCR was utilized to measure the expression of TGF-β/Smad2/3 signalling, α-SMA, and type I collagen gene expression. Results Mangosteen extract exerted higher cytotoxicity of fibrotic buccal mucosal fibroblasts compared to normal cells. Furthermore, mangosteen-receiving cells exhibited downregulation in the expression of the TGF-β/Smad2 pathway, as well as reduced expression of α-SMA and type I collagen. Conclusion Findings from this study suggest that mangosteen could serve as a promising agent for averting the progression of oral fibrogenesis and halting the malignancy of the oral epithelium in patients with OSF.
