Abstract
ABSTRACT Chronic osteomyelitis is a bone disease that is characterized by inflammatory processes, including necrosis of mineralized and marrow tissues, suppuration, resorption, sclerosis, and hyperplasia. The primary cause of chronic osteomyelitis is usually microbiologic, and it results from an odontogenic infection, postextraction complication, inadequate removal of necrotic bone, early termination of antibiotic therapy, inappropriate selection of antibiotics, diagnostic failure, trauma, inadequate treatment for a fracture, or irradiation to the mandible. The incidence of malignant transformation of chronic osteomyelitis in the head and neck region is very low and rare in developed countries. This is the first case report on the malignant transformation of chronic osteomyelitis of the mandible which discusses its etiopathogenesis and radiographic imaging.

Abstract
This review aims to understand the concept of oral cancer immunology through the notion of immune profiling, immunoediting and immunotherapy, and to gain knowledge regarding its application for the management of oral cancer patients. Oral cancer is an immunogenic tumor where the cells of the tumor microenvironment play an important role in tumorigenesis. Understanding the mechanism of these modulations can help design immunotherapeutic strategies in oral cancer patients. This article gives an overview of immunomodulation in the oral cancer tumor microenvironment, with concepts of immune profiling, immunoediting and immunotherapy. English literature searches via Google Scholar, Web of Science, EBSCO, Scopus, and PubMed database were performed with the key words immunology, tumor microenvironment, cells, cross talk, immune profiling, biomarkers, inflammation, gene expression, techniques, immunoediting, immunosurveillance, tumor escape, immunotherapy, immune checkpoint inhibitors, vaccines in cancer, oral cancer, and head and neck cancer. Original research articles, reviews, and case reports published from 2016-2021 (n = 81) were included to appraise different topics, and were discussed under the following subsections. Literature published on oral cancer immunology reveals that oral cancer immune profiling with appropriate markers and techniques and knowledge on immunoediting concepts can help design and play an effective role in immunotherapeutic management of oral cancer patients. An evaluation of oral cancer immunology helps to determine its role in tumorigenesis, and immunotherapy could be the emerging drift in the effective management of oral cancer.

Anticancer and antioxidant profiling effects of Nerolidol against DMBA induced oral experimental carcinogenesis. J Biochem Mol Toxicol 2022; 36:e23029. [PMID: 35243731 DOI: 10.1002/jbt.23029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Revised: 11/03/2021] [Accepted: 01/05/2022] [Indexed: 11/10/2022]
Abstract
The objective of this study is to examine the chemopreventive effects of Nerolidol (NER) on hamster buccal pouch carcinogenesis (HBC) induced by 7,12-dimethylbenz(a)anthracene (DMBA) in male golden Syrian hamsters. In this study, oral squamous cell carcinoma was developed in the buccal pouch of an oral painted hamster with 0.5% DMBA in liquid paraffin three times weekly for 12 weeks. To assess DMBA-induced hamster buccal tissue carcinogenesis, biochemical endpoints such as Phase I and II detoxification enzymes, antioxidants, lipid peroxidation (LPO) by-products, and renal function markers, as well as histopathological examinations, were used. Furthermore, the immunohistochemical studies of interleukin-6 were investigated to find the inflammatory link in the HBC carcinogenesis. In our results, DMBA alone exposed hamsters showed 100% tumor growth, altered levels of antioxidants, detoxification agents, LPO, and renal function identifiers as compared to the control hamsters. The outcome in present biochemical, histopathological, and immunohistochemistry studies has been found a reverse in NER-treated hamsters against the tumor. This study concluded that NER modulated the biochemical profiles (antioxidants, detoxification, LPO, and renal function markers) and inhibited tumor development in DMBA induced oral carcinogenesis.

Abstract
OBJECTIVES In the search for more effective and safe treatment avenues, we investigated cold physical plasma as a new treatment modality for therapy of oral lichen planus (OLP). MATERIAL AND METHODS Healthy and diseased human mucosal tissue samples with a size of 3 mm in diameter obtained from OLP patients were subjected to plasma treatment ex vivo or were left untreated. Tissue sections were quantified for immune-infiltration of CD4+ , CD8+ , CD45RA+ , and CD45R0+ T cells. Moreover, the tissues' inflammatory profile was assessed by analyzing 12 different cytokines in the surrounding media. RESULTS A significantly increased infiltrate of CD8+ and CD45-R0+ T cells was detected in OLP tissue samples when compared to healthy tissue. A higher concentration of interleukin (IL) 1β, IL6, IL8, and granulocyte macrophage-colony stimulating factor (GM-CMF) was detected in OLP samples compared to healthy mucosal tissue. For all cytokines and chemokines investigated, 23 out of 24 comparisons showed a decrease in tendency (significant for IL1β, IL2, IL10, and GM-CSF) in response to plasma treatment. In ex vivo-treated tissue, a decrease of T-cell infiltrate in OLP lesions compared with healthy tissue was observed. CONCLUSION Our findings suggest cold physical plasma can be a promising therapeutic option for OLP that requires further validation in vivo.

Abstract
OBJECTIVE The aim of this study is to analyze the tongue epithelial response to cigarette smoke exposure on a number of macrophages, lymphocytes, plasma cells, and matrix metalloproteinase 9 (MMP-9) expression to determine the risk factor of oral cancer development. MATERIALS AND METHODS Thirty Rattus norvegicus will be exposed to two kinds of cigarette smoke by a smoking pump for 4 and 8 weeks. The tongues were collected to analyze the number of macrophages, lymphocytes, and plasma cells with hematoxylin-eosin. The MMP-9 expression was similarly analyzed with immunohistochemical staining and then compared with the control group. RESULTS The number of macrophages, lymphocytes, and MMP-9 expression was higher in the 8-week cigarette smoke exposure compared to the 4-week cigarette smoke exposure and the control group (p < 0.000). The number of plasma cell did not differ in the 8-week cigarette smoke exposure from that of the control group (p > 0.05). The number of plasma cells in the tongue tissue during the 4-week cigarette smoke exposure was not determined. CONCLUSION Cigarette smoke exposure induces the risk of oral cancer development as a result of an increase in the number of macrophages, lymphocytes, and MMP-9 expression in the tongue epithelial.

Abstract
OBJECTIVES To study the association of Candida and antifungal therapy with pro-inflammatory cytokines (PIC) in oral leukoplakia (OL). MATERIALS AND METHODS A prospective observational study where immunocompetent adult subjects with OL (30 homogenous (HL), 30 non-homogenous (NHL)) and 30 age and sex-matched healthy controls (C) with no predisposing factors for oral Candida infection were recruited. Sterile cotton swabs and ophthalmic sponges were used to sample the lesion surface in OL and buccal mucosa in C, for direct microscopy and culture for Candida and to determine levels of PIC (IL-6, IL-8. IL-17, TNF-α) by ELISA, respectively. Sampling for PIC was repeated at same sites in OL, 2 weeks after antifungal therapy. RESULTS Candida was associated with 55.3% of NHL, 23.3% of HL and 13.3% of C. The oral secretary levels of PIC were raised in NHL as compared to HL and C. The levels of IL-6, IL-8, TNF-α (p<0.001) and IL-17 (p<0.01) were significantly raised in Candida positive NHL while IL-6 (p<0.05) and TNF-α (p<0.01) were significantly raised in Candida positive HL before antifungal treatment. After antifungal treatment, there was significant reduction in PIC in Candida positive NHL and HL. CONCLUSIONS Candida infection contributes to the inflammatory milieu in Candida associated OL which increases the risk of carcinogenesis. Antifungal therapy reduces the PIC in Candida associated OL. CLINICAL RELEVANCE Identification and elimination of predisposing factors for Candida infection, like cessation of harmful habits, maintenance of oral/denture hygiene, surveillance for Candida and antifungal therapy at intervals, are recommended in OL. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT04712929.

Abstract
Objectives To determine the association of Candida phenotypes, virulence factors, antifungal sensitivity and clinical response to Fluconazole in Oral leukoplakia (OL). Methods Sterile swabs were obtained from oral lesions in immunocompetent subjects [30 Homogenous (HOL), 31 Non- Homogenous (NHOL] and normal buccal mucosa in 30 age and sex-matched healthy controls (C). Candida phenotypes, virulence factors (Secreted Aspartyl Proteinase (SAP), Phospholipase (PL), Biofilm formation (BF) and antifungal sensitivity were determined. Clinical features (Size, Erythema, thickness, oral burning sensation (VAS scores) before and after Fluconazole therapy in OL were recorded by two calibrated observers. Results Candida was associated with OL (p < 0.01). Candida albicans was the most common phenotype sensitive to Fluconazole. SAP, PL and BF activity was significantly high in NHOL. Strong positive correlation was seen between SAP, and PL activity and pre-treatment VAS scores in NHOL. There was significant reduction in VAS scores, size of lesion [HOL (p < 0.001) NHOL (p < 0.05)], erythematous areas (67.8%) in NHOL and thickness of lesions (42.6%) in both types OL after Fluconazole therapy with substantial inter-observer agreement. Non albicans candida (NAC) species had similar virulence profiles but resistant to Fluconazole and showed minimal clinical improvement. Conclusions Virulence activity of Candida in OL increases severity of lesions. Fluconazole is effective against virulent Candida albicans, causes clinical improvement and down-staging from high -risk NHOL to low-risk HOL which can reduce risk of malignant transformation. Detection of highly virulent NAC infection and antifungal sensitivity is recommended in OL recalcitrant to Fluconazole therapy.

Abstract
The objective was to assess the effects of non-steroidal anti-inflammatory drugs (NSAIDs) on head and neck cancer (HNC) outcomes. A systematic review was conducted following the PRISMA guidelines. The MEDLINE and the Cochrane Central Register databases were searched. Risk of bias was assessed by the Cochrane Collaboration's tool and by the Newcastle-Ottawa Scale. Meta-analyses were performed with the RevMan software. Seventeen articles met the inclusion criteria. Quality scores for observational studies ranged between 5 and 8 stars and the RCT was assessed as high risk of bias. NSAIDs use was associated with a 13% risk reduction of HNC (OR: 0.87 95% CI 0.77-0.99). NSAIDs use was associated with a 30% reduced cancer-specific mortality and with a 40% decreased risk on disease-recurrence. NSAIDs may have a modest protective effect on HNC risk and a positive impact on cancer-specific survival and disease-recurrence. The findings do not support a protective role of aspirin on HNC outcomes.

Abstract
The present study examines the chemopreventive role of [6]-gingerol, an active component of ginger, on 7,12-dimethylbenz[a]anthracene (DMBA)-induced hamster buccal pouch (HBP) carcinogenesis models. The HBP has been developed with an addition of 0.5% of DMBA to the HBP area three times per week, up to the end of the 16th experimental week. At the end of the experiment, we noticed 100% tumor incidence and precancerous lesions, such as dysplasia, hyperplasia, keratosis, and well-differentiated squamous cell carcinoma, in DMBA-induced HBP. Furthermore, we observed that [6]-gingerol inhibited the increased thiobarbituric acid-reactive substances and decreased antioxidant levels in DMBA-induced hamsters. Moreover, [6]-gingerol inhibits DMBA-exposed over expression of inflammatory markers (inducible nitric oxide synthase, interleukin [IL]-1β, IL-6, cyclooxygenase-2, and tumor necrosis factor-α) and cell proliferation markers (cyclin D1, proliferating cell nuclear antigen); induces proapoptotic markers in HBP. Nuclear factor erythroid-2-related factor-2 (Nrf2) is a major antioxidant transcription factor, which regulates the antioxidant gene-dependent scavenge of tumor proliferation and apoptosis. Overexpression of Nrf2 signaling plays a pivotal role and can be a novel target in preventing carcinogenesis. In this study, [6]-gingerol restores the DMBA-induced depletion of Nrf2 signaling and thereby prevents buccal pouch carcinogenesis in hamsters. These results point out that [6]-gingerol impedes the responses of inflammatory and cell proliferation-associated progression of cancer through the action of Nrf2 signaling.

Abstract
OBJECTIVES A narrative review on the NO properties and their relationship with the oral environment describing NO's molecular origin, role, and perspectives regarding oral pathological, physiological, and regenerative processes for future applications and possible use as prevention or treatment in dentistry. MATERIALS AND METHODS Pubmed was searched using the word "nitric oxide." Reviews, clinical studies, and experimental studies were eligible for the screening process. Similar search procedures were then performed with the additional search words "conservative dentistry," "orthodontics," "endodontics," "implants," "periodontics," "oral cancer," "pulp revascularization," and "oral surgery." Furthermore, references of included articles were examined to identify further relevant articles. RESULTS There is a relationship between NO production and oral diseases such as caries, periodontal diseases, pulp inflammation, apical periodontitis, oral cancer, with implants, and orthodontics. Studies on this relationship and uses of NO, in diagnosis, prevention, and treatment, are being developed. Also, some NO and oral cavity patents have already registered. CONCLUSIONS The understanding of how NO can interfere in oral health maintenance or disease processes can contribute to elucidate the disease development and optimize treatment approaches. CLINICAL RELEVANCE NO has considerable biotechnological potential and can contribute to improving diagnostics and treating the oral environment. As a biomarker, NO has an important role in the early diagnosis of diseases. Regarding treatments, NO can possibly be used as a regulator of inflammation, anti-biofilm action, replacing antibiotics, inducing apoptosis of cancerous cells, and contributing to the angiogenesis. All these studies are initial considerations regarding the relationship between NO and dentistry.

Abstract
Fast, economic, and noninvasive, molecular analysis of saliva has the potential to become a diagnostic tool of reference for several local and systemic diseases, oral cancer included. The diagnosis of Oral Squamous Cell Carcinoma (OSCC) can be performed using high specificity and sensibility biomarkers that can be encountered in the biological fluids. Recent advances in salivary proteomics have underlined the potential use of salivary biomarkers as early diagnosis screening tools for oral neoplasia. In this respect, over 100 salivary molecules have been described and proposed as oral cancer biomarkers, out of which cytokines are among the most promising. Besides being directly involved in inflammation and immune response, the role of salivary cytokines in tumor growth and progression linked them to the incidence of oral malignant lesions. This review summarizes the existing studies based on the use of salivary cytokines as potential oral cancer biomarkers, their involvement in the malignant process based on their type, and ther influence upon prognostic and metastatic rates.

Abstract
The long noncoding RNA T cell receptor gamma locus antisense RNA 1 (TRG-AS1) plays an important role in glioblastoma progression. The objective of this study was to determine the expression status of TRG-AS1 in tongue squamous cell carcinoma (TSCC). The regulatory effects of TRG-AS1 depletion on the malignant processes of TSCC cells were illustrated both in vitro and in vivo. Additionally, the precise molecular mechanisms through which TRG-AS promotes TSCC oncogenicity were investigated. TRG-AS1 expression in TSCC tissues and cell lines was detected using reverse transcription-quantitative PCR. Functional experiments including Cell Counting Kit-8 assay, flow cytometric apoptotic assay, migration and invasion assays, and xenograft tumor model analysis were conducted to severally determine the effects of TRG-AS1 on TSCC cell proliferation, apoptosis, migration, and invasion in vitro and tumor growth in vivo. Herein, TRG-AS1 was highly expressed in TSCC and closely associated with advanced TNM stage, high lymph node metastasis, and poor overall survival. Functionally, TRG-AS1 depletion suppressed TSCC cell proliferation, migration, and invasion in vitro; promoted cell apoptosis; and attenuated tumor growth in vivo. Mechanistically, TRG-AS1 served as a molecular sponge for microRNA-543 (miR-543), thereby contributing to the increased expression of Yes-associated protein 1 (YAP1) - a miR-543 target. Rescue experiments confirmed that miR-543 inhibition or YAP1 overexpression abrogated the anticancer effects of TRG-AS1 silencing in TSCC cells. In conclusion, TRG-AS1 aggravates TSCC malignancy by regulating the miR-543/YAP1 axis. Identification of the TRG-AS1/miR-543/YAP1 regulatory pathway may provide novel insights into TSCC diagnosis, prognosis, and therapy.

RID: Evaluation of the Possible Inhibiting Effect of the Proinflammatory Signaling Induced by TNF- α through NF- κβ and AP-1 in Two Cell Lines of Breast Cancer. Mediators Inflamm 2020; 2020:2707635.

Abstract
Receptor internalization and degradation (RID), is a transmembrane protein coded within the E3 region expression cassette of adenoviruses. RID downregulates the cell surface expression of epidermal growth factor receptor (EGFR), tumor necrosis factor receptor (TNFR), and apoptosis antigen 1 (FAS), causing a reduction of the effects of their respective ligands. In addition, RID inhibits apoptosis by decreasing the secretion of TNF-related apoptosis-inducing ligand (TRAIL) by normal tissue cells. In this article, we report that RID inhibited chemokine expression in human breast cancer cell line MDA-MB-231 but showed no effect in cell line MCF7. These dissimilar results may be due to the different molecular and functional properties of both cell lines. Therefore, it is necessary to replicate this study in other breast cancer cell models.

Modulation of salivary cytokines in response to alcohol, tobacco and caffeine consumption: a pilot study. Sci Rep 2018; 8:16687.

Abstract
It has been shown that long-term stimulant consumption alters the biological and microbiological status of the oral cavity. We present a pilot study describing stimulant-specific oral immunomodulation in the oral cavity. Changes in salivary cytokine levels in response to long-term alcohol, tobacco and caffeine were identified. Volunteers were recruited from amongst the patients visiting University Dental Clinic of CEU Cardenal Herrera University (Alfara del Patriarca, Spain). Participants were grouped according to their self-reported levels of consumption of either caffeine, alcohol or tobacco (control group volunteers were non-consumers of all three). Informed consent was provided and stimulated saliva samples were obtained and assayed for interleukin-1α IL-1α), Tumor Necrosis Factor α (TNF-α) and Interferon γ IFN-γ). Long-term, high-level consumers of alcohol or tobacco exhibited elevated salivary concentrations of the three inflammatory cytokines with respect to control values. Specifically, IL-1α was found to be elevated in alcohol users whilst IFN-γ concentration higher in tobacco users versus controls. Long-term caffeine consumers displayed elevated levels of IFN-γ and TNF-α, whereas IL-1α levels were reduced with respect to control volunteers. This pilot study demonstrates that salivary cytokines can be modulated in response to quantity and duration of alcohol, caffeine or tobacco consumption.

Abstract
Oral cancer is often painful and lethal. Oral cancer progression and pain may result from shared pathways that involve unresolved inflammation and elevated levels of pro-inflammatory cytokines. Resolvin D-series (RvDs) are endogenous lipid mediators derived from omega-3 fatty acids that exhibit pro-resolution and anti-inflammatory actions. These mediators have recently emerged as a novel class of therapeutics for diseases that involve inflammation; the specific roles of RvDs in oral cancer and associated pain are not defined. The present study investigated the potential of RvDs (RvD1 and RvD2) to treat oral cancer and alleviate oral cancer pain. We found down-regulated mRNA levels of GPR18 and GPR32 (which code for receptors RvD1 and RvD2) in oral cancer cells. Both RvD1 and RvD2 inhibited oral cancer proliferation in vitro. Using two validated mouse oral squamous cell carcinoma xenograft models, we found that RvD2, the more potent anti-inflammatory lipid mediator, significantly reduced tumor size. The mechanism of this action might involve suppression of IL-6, C-X-C motif chemokine 10 (CXCL10), and reduction of tumor necrosis. RvD2 generated short-lasting analgesia in xenograft cancer models, which coincided with decreased neutrophil infiltration and myeloperoxidase activity. Using a cancer supernatant model, we demonstrated that RvD2 reduced cancer-derived cytokines/chemokines (TNF-α, IL-6, CXCL10, and MCP-1), cancer mediator-induced CD11b+Ly6G- myeloid cells, and nociception. We infer from our results that manipulation of the endogenous pro-resolution pathway might provide a novel approach to improve oral cancer and cancer pain treatment.

Abstract
OBJECTIVES This paper aims to systematically review current findings on altered expression of miRNAs in OPMDs and whether they can be used as risk stratification biomarkers. METHODS Studies were collated after searching three different electronic databases: PubMed, Embase, Medline. Additional searches were carried out through cross checking the bibliographies of selected articles. After a thorough selection process made by two of the authors, 40 articles met the inclusion criteria and were included in the review. Studies were assessed and analysed in terms of how the candidate miRNA biomarkers were differentially expressed and validated. RESULTS The included studies examined the expression of miRNAs from human specimens (blood serum/plasma, saliva, tissue) as diagnostic or prognostic biomarkers in patients with OPMDs, some of which have been utilised as risk stratification biomarkers for malignant transformation and have showed promising findings. CONCLUSION The current evidence to support or refute the prognostic utility of miRNAs in predicting cancer progression in OPMDs is equivocal. Further longitudinal prospective studies with solid study design are warranted.
