Abstract
A chronic, persistent, possibly cancerous condition that mostly affects the oral cavity is called oral submucous fibrosis (OSMF) and causes severe functional impairment. Due to its complex nature, OSMF requires a comprehensive strategy that includes both surgical and medication therapies. Multidisciplinary treatment was started, which included a complete stoppage of habit, dental hygiene precautions, dietary counselling, surgical intervention, supportive medicinal therapy, and physiotherapy. Following surgery and adjunct therapy, the patient's mouth opening and functional results were improved. The patient is kept for regular follow-up to assess the recurrence of fibrosis or any incidence of malignant transformation. This case emphasizes the difficulties in treating advanced OSMF and emphasizes how crucial it is to improve patient outcomes by early detection, stopping betel nut chewing, and thorough multidisciplinary care.

Knockdown of Notch Suppresses Epithelial-mesenchymal Transition and Induces Angiogenesis in Oral Submucous Fibrosis by Regulating TGF-β1. Biochem Genet 2024; 62:1055-1069. [PMID: 37526864 DOI: 10.1007/s10528-023-10452-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 07/06/2023] [Indexed: 08/02/2023]
Abstract
Oral submucous fibrosis (OSF) is a chronic disorder with a high malignant transformation rate. Epithelial-mesenchymal transition (EMT) and angiogenesis are key events in OSF. The Notch signaling plays an essential role in the pathogenesis of various fibrotic diseases, including OSF. Our study aimed to explore the effects of Notch on the EMT and angiogenesis processes during the development of OSF. The expression of Notch in OSF tissues versus normal buccal mucosa samples was compared. Arecoline was used to induce myofibroblast transdifferentiation of buccal mucosal fibroblasts (BMFs). Short hairpin RNA technique was used to knockdown Notch in BMFs. Pirfenidone and SRI-011381 were used to inhibit and activate the TGF-β1 signaling pathway in BMFs, respectively. The expression of Notch was markedly upregulated in OSF tissues and fibrotic BMFs. Knockdown of Notch significantly decreased the viability and promoted apoptosis in BMFs subjected to arecoline stimulation. Downregulation of Notch also significantly suppressed the EMT process, as shown by the reduction of N-cadherin and vimentin with concomitant upregulation of E-cadherin. In addition, knockdown of Notch upregulated VEGF and enhanced the angiogenic activity of fBMFs. Moreover, inhibition of TGF-β1 suppressed viability and EMT, promoted apoptosis, and induced angiogenesis of fBMFs, while activation of TGF-β1 significantly diminished the effects of Notch knockdown on fBMFs. Knockdown of Notch suppressed EMT and induced angiogenesis in OSF by regulating TGF-β1, suggesting that the Notch-TGF-β1 pathway may serve as a therapeutic intervention target for OSF.

Pal S, Sharma D, Yadav NP. Plant leads for mitigation of oral submucous fibrosis: Current scenario and future prospect. Oral Dis 2024; 30:80-99. [PMID: 36565439 DOI: 10.1111/odi.14485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 11/25/2022] [Accepted: 12/20/2022] [Indexed: 12/25/2022]
Abstract
The aim of this review is to enumerate medicinal plants and their bioactive compounds that may become potential leads in the mitigation of oral submucous fibrosis (OSMF) in the forthcoming future. It is focused on pathophysiology, risk factors, current treatment regimen, potential plant leads, and future therapies for OSMF. Data were extracted from a vast literature survey by using SciFinder, Web of Science, Google Scholar, and PubMed search engines with relevant keywords. Upon literature survey, we found that the phytochemical 'arecoline' present in the areca nut is the main causative agent of OSMF condition. Currently, OSMF is treated by immunomodulatory and anti-inflammatory agents such as corticosteroids, enzymes (hyaluronidase, chymotrypsin, and collagenase), anti-inflammatory mediators (isoxsuprine and pentoxifylline), dietary supplements (vitamins, antioxidants, and micronutrients), and anti-fibrotic cytokines like interferon-gamma that provides short-term symptomatic relief to OSMF patients. However, some plant leads have been proven effective in alleviating symptoms and mitigating OSMF, which ultimately improves the quality of OSMF patients' life. We concluded that plant drugs like lycopene, curcumin, Aloe vera, colchicine, and Glycyrrhiza glabra are effective against OSMF in various in vitro and/or clinical studies and are being used by modern and traditional practitioners.

Abstract
The prevalent symptoms of oral submucous fibrosis (OSMF) are a burning sensation and trismus. The aim of the present study was to compare the efficacy of placentrex, hyaluronidase and dexamethasone, and their combination in the treatment of OSMF. For this purpose, 160 patients with OSMF were divided into four groups (each with 40 patients at a 1:1:1:1 allocation ratio). The patients in group 1 (control) received only oral supplements, along with regular mouth-opening exercises; patients in group 2 received an injection of placental extract; patients in group 3 were injected with hyaluronidase and dexamethasone; and patients in group 4 received a combination of injections from groups 2 and 3. The injections were administered once weekly for 12 weeks and patients were followed-up for 12 months. The data of the patients (mouth opening ability and a burning sensation) were analyzed using ANOVA and the Kruskal-Wallis test. The maximum increase in mouth opening (7.30±0.80 mm) was noted in group 4, and the lease increase was observed in the control group (0.37±0.16 mm), from baseline levels to the end of the 12th week. The maximum relapse in mouth opening of 1.62±0.45 mm was noted in group 2, and a minimum relapse of 0.20±0.08 mm was noted in group 4. On the whole, the present study demonstrates that the intralesional injection of a combination of the three drugs (placentrex, hyaluronidase and dexamethasone) in addition to the use of oral supplements and mouth opening exercises has a high level of efficacy in improving trismus and burning sensation in patients with OSMF.

Antifibrotic effect of silymarin on arecoline-induced fibrosis in primary human buccal fibroblasts: an in silico and in vitro analysis. Mol Biol Rep 2024; 51:303. [PMID: 38356030 DOI: 10.1007/s11033-023-09177-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Accepted: 12/18/2023] [Indexed: 02/16/2024]
Abstract
BACKGROUND This study aimed to assess silymarin's anticancer and antifibrotic potential through in silico analysis and investigate its impact on in vitro arecoline-induced fibrosis in primary human buccal fibroblasts (HBF). METHODS & RESULTS The study utilized iGEMDOCK for molecular docking, evaluating nine bioflavonoids, and identified silymarin and baicalein as the top two compounds with the highest target affinity, followed by subsequent validation through a 100ns Molecular Dynamic Simulation demonstrating silymarin's stable behavior with Transforming Growth Factor Beta. HBF cell lines were developed from tissue samples obtained from patients undergoing third molar extraction. Arecoline, a known etiological factor in oral submucous fibrosis (OSMF), was employed to induce fibrogenesis in these HBFs. The inhibitory concentration (IC50) of arecoline was determined using the MTT assay, revealing dose-dependent cytotoxicity of HBFs to arecoline, with notable cytotoxicity observed at concentrations exceeding 50µM. Subsequently, the cytotoxicity of silymarin was assessed at 24 and 72 h, spanning concentrations from 5µM to 200µM, and an IC50 value of 143µM was determined. Real-time polymerase chain reaction (qPCR) was used to analyze the significant downregulation of key markers including collagen, epithelial-mesenchymal transition (EMT), stem cell, hypoxia, angiogenesis and stress markers in silymarin-treated arecoline-induced primary buccal fibroblast cells. CONCLUSION Silymarin effectively inhibited fibroblast proliferation and downregulated genes associated with cancer progression and EMT pathway, both of which are implicated in malignant transformation. To our knowledge, this study represents the first exploration of silymarin's potential as a novel therapeutic agent in an in vitro model of OSMF.

Abstract
BACKGROUND Oral submucous fibrosis (OSMF) is a chronic, potentially malignant disorder characterized by progressive fibrosis of the oral mucosa, leading to restricted mouth opening and discomfort. This study investigates the efficacy and safety of astaxanthin, a potent antioxidant and anti-inflammatory carotenoid, in the comprehensive management of OSMF. METHODS A randomized, double-blind, placebo-controlled trial was conducted with 68 eligible participants diagnosed with OSMF. Participants were randomly assigned to the experimental group (astaxanthin capsules, 5 mg twice daily) or the control group (placebo capsules) for 12 weeks. Primary outcomes included changes in mouth opening and burning sensation assessed by Visual Analog Scale (VAS). Adverse events were monitored to evaluate safety. RESULTS The experimental group demonstrated a statistically significant improvement in mouth opening compared to the control group over the 12-week intervention (p < 0.001). Additionally, the experimental group reported a significant reduction in burning sensation, as indicated by VAS scores (p < 0.001). Adverse events were generally mild and comparable between groups. CONCLUSION This study suggests that astaxanthin may have a positive impact on mouth opening and burning sensation in individuals with OSMF. The safety profile observed supports the feasibility of astaxanthin as a potential therapeutic adjunct in OSMF management. Further research with larger sample sizes and extended follow-up periods is warranted to validate these findings.

Abstract
Oral submucous fibrosis (OSF) is an oral condition characterized by chronic progression, which may lead to the development of malignancy. Currently, available treatments for OSF only provide temporary relief of symptoms, and there is a limited availability of effective interventions that can effectively cure this condition. In this study, we aimed to investigate whether adiponectin (APN) could ameliorate OSF and the mechanisms involved in it. First, human oral mucosal fibroblasts (HOMFs) were cultured, an OSF model was established using arecoline, and APN and Imiquimod treatment were administered. Then we overexpressed NLRP3 and knocked down FOXO3A. FOXO3A, fibrosis-related factors (ɑ-SMA, COL1A, CTGF), TGF-β1/Smad3 signaling-related factors (TGF-β1, p-Smad3, Smad3), NLRP3 inflammasome-related factors (NLRP3, Caspase-1, IL-1β), and ROS levels were evaluated. Finally, we explored the effect of APN on OSF in mice by in vivo experiments. We found that arecoline significantly increased ɑ-SMA, COL1A, CTGF, and TGF-β1 expressions and promoted Smad3 phosphorylation, while APN significantly inhibited the elevation of these fibrosis-related factors. ROS production was significantly elevated in HOMFs after arecoline treatment, while APN treatment inhibited ROS production. However, the addition of Imiquimod and overexpression of NLRP3 exhibited a trend of elevated ROS, resisting the inhibitory effect of APN. Furthermore, adding Imiquimod and overexpression of NLRP3 elevated ɑ-SMA, COL1A and CTGF and activated TGF-β1/Smad3 signaling pathway. Additionally, knockdown of FOXO3A enhanced APN-inhibited ɑ-SMA and COL1A. In vivo experiments further confirmed that APN ameliorated OSF in mice by inhibiting ROS/NLRP3 inflammatory pathway. In conclusion, APN ameliorated arecoline-induced OSF by promoting FOXO3A expression and downregulating the ROS/NLRP3 pathway.

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.

Abstract
OBJECTIVE To investigate the mechanism by which arecoline regulates the level of miR-155-5p in macrophage-secreted exosomes to induce the transformation of human oral mucosal fibroblasts (HOMFs) into fibroblast phenotype. METHODS Exosomes were harvested from human monocytic cell line THP-1 with or without arecoline treatment. The effects of arecoline-treated THP-1 cell culture supernatant (CS), THP-1-derived exosomes (EXO), exosome-depleted THP-1 cell supernatant (NES), miR-155-5p overexpression, and miR-155-5p inhibitor on migration ability of arecoline-treated HOMF cells were examined using Transwell migration assay. The polarization of THP-1 cells was detected using flow cytometry. DCFH-DA was used to detect the level of oxidative stress in the cells with different treatments. The mRNA and protein expressions of α- SMA, type I collagen and SOCS1 in the cells were detected with qRT-PCR and Western blotting. RESULTS Flow cytometry showed that arecoline-treated THP-1 cells exhibited obvious polarization from M0 to M1. Both the supernatant and exosomes from arecoline-treated THP-1 cells significantly enhanced the migration ability of HOMF cells, increased intracellular oxidative stress, up-regulated the expressions of miR-155- 5p and the mRNA and protein levels of α-SMA and type I collagen, and lowered the mRNA and protein expressions of SOCS1. In HOMF cells treated with exosomes from arecoline- treated THP-1 cells, overexpression of miR-155-5p significantly enhanced cell migration ability and increased cellular expressions of α-SMA and type I collagen, and miR-155-5p inhibitor caused the opposite changes. CONCLUSION Arecoline can up-regulate miR-155-5p expression in THP-1 cells and inhibit the expression of SOCS1 protein in HOMF cells via the exosome pathway, thus promoting the fibrotic phenotype transformation of HOMF cells.

Abstract
OBJECTIVES There is currently a lack of economic and suitable animal models that can accurately recapitulate the oral submucous fibrosis (OSF) disease state for indepth study. This is one of the primary reasons for the limited therapeutic methods available for OSF. Based on the underlying logic of pan-cancer analysis, this study systematically compares OSF and the other four types of organ fibrosis from the aspects of molecules, signaling pathways, biological processes, etc. A comprehensive analysis of the similarities and differences between OSF and other organ fibrosis is helpful for researchers to discover some general rules of fibrosis disease and may provide new ideas for studying OSF. METHODS Microarray data of the GSE64216, GSE76882, GSE171294, GSE92592, and GSE90051 datasets were downloaded from GEO. Differentially expressed mRNAs (DEmRNAs) of each type of fibrosis were identified by Limma package. Weighted gene co-expression network analysis (WGCNA) was used to identify each type of fibrosis-related module. The similarities and differences of each fibrosis-related-module genes were analyzed by function and pathway enrichment analysis. RESULTS A total of 6 057, 10 910, 27 990, 10 480, and 4 801 DEmRNAs were identified in OSF, kidney intestinal fibrosis (KIF), liver fibrosis (LF), idiopathic pulmonary fibrosis (IPF), and skin fibrosis (SF), respectively. By using WGCNA, each type of fibrosis-related module was identified. The co-expression networks for each type of fibrosis were constructed respectively. Except that KIF and LF have 5 common hub genes, other fibrotic diseases have no common hub genes with each other. The common pathways of OSF, KIF, LF, IPF, and SF mainly focus on immune-related pathways. CONCLUSIONS OSF and the other 4 types of fibrotic diseases are tissue- and organ-specific at the molecular level, but they share many common signaling pathways and biological processes, mainly in inflammation and immunity.
