Abstract
Oral lichen planus (OLP) is a premalignant disease with unknown etiology. It has been demonstrated that inflammation and immune activation play a central role in the pathogenesis of OLP. Various cellular and molecular mechanisms are involved in the pathogenesis of OLP. Studies have shown that 2-7% of OLP patients develop oral squamous cell carcinoma (OSCC). As a result, determining the prognosis of the disease will be promising in preventing oral carcinoma. MicroRNAs are involved in the regulation of cytokine expression and cytokines have a central role in the pathogenesis of OLP. As a result, their evaluation in body fluids may be helpful in assessing the disease's status and progression, and facilitating the treatment process. In this regard, much attention has been paid to the saliva of OLP patients as the sampling is cost-effective and non-invasive. Here, we discuss the potential of miRNAs in predicting the disease severity and progression.

Abstract
Oral lichen planus (OLP) is a localized autoimmune disease of the oral mucosa, with an incidence of up to 2%. Although corticosteroids are the first-line treatment, they cause several adverse effects. Quercetin, a naturally occurring compound, has fewer side-effects and provides long-term benefits. Besides, it has powerful anti‑inflammatory activities. Here, we combined network pharmacology with experimental verification to predict and verify the key targets of quercetin against OLP. First, 66 quercetin-OLP common targets were analyzed from various databases. The protein–protein interaction (PPI) network was constructed. Topology analysis and MCODE cluster analysis of common targets were conducted to identify 12 key targets including TP53, IL-6 and IFN-γ and their connections. Gene functions and key signaling pathways, including reactive oxygen species metabolism, IL-17 pathway and AGE-RAGE pathway, were enriched by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Then, in vitro experiments showed that quercetin interfered with Th1/Th2 balance by acting on IL-6 and IFN-γ to modulate the immune system in treating OLP. Quercetin considerably affected the apoptosis and migration of T lymphocytes in OLP patients. Our study reveals the potential therapeutic targets and signaling pathways of quercetin associated with OLP, and establishes the groundwork for future clinical applications.

Abstract
Oral lichen planus (OLP) is one of the autoimmune diseases associated with chronic inflammation that involves several complications including the potential for malignant transformation into oral squamous cell carcinoma. Pathogenesis of OLP are yet to be fully comprehended however, it has been demonstrated that the epithelial cells in OLP lesions are affected by cytotoxic T lymphocytes leading to immunological reactions. Various factors are reported to act as diagnostic markers for predicting and monitoring the cancerous progression. Hence, in this review, we summarize and present the latest studies regarding the predictive markers associated with malignant potential of OLP.

Abstract
OBJECTIVES The objective of this study was to investigate the association between p53 expression and microbial acetaldehyde production in patients with oral squamous cell carcinoma (OSCC). STUDY DESIGN Oral mucosal biopsies from 22 patients with OSCC and 24 healthy controls (HCs) were collected. p53 expression was analyzed by immunohistochemistry. Microbial samples were collected from the mucosa and microbial acetaldehyde production from ethanol was measured by gas chromatography. RESULTS The majority of all OSCC (77%) and HC samples (67%) produced mutagenic levels of acetaldehyde (>100 µM). A significant positive correlation between microbial acetaldehyde production and p53 expression levels in OSCC samples was seen in the intermediate and superficial layers of the epithelium of the infiltrative zone (P = .0005 and P = .0004, respectively) and in the superficial layer of the healthy appearing mucosa next to the tumor (P = .0391). There was no significant correlation between acetaldehyde levels and p53 expression in HC samples. CONCLUSIONS Our results show an association between microbial acetaldehyde production and immunostaining of p53 in OSCC samples.

The specific seroreactivity to ∆Np73 isoforms shows higher diagnostic ability in colorectal cancer patients than the canonical p73 protein. Sci Rep 2019; 9:13547.

Abstract
The p53-family is tightly regulated at transcriptional level. Due to alternative splicing, up to 40 different theoretical proteoforms have been described for p73 and at least 20 and 10 for p53 and p63, respectively. However, only the canonical proteins have been evaluated as autoantibody targets in cancer patients for diagnosis. In this study, we have cloned and expressed in vitro the most upregulated proteoforms of p73, ΔNp73α and ΔNp73β, for the analysis of their seroreactivity by a developed luminescence based immunoassay test using 145 individual plasma from colorectal cancer, premalignant individuals and healthy controls. ∆Np73α seroreactivity showed the highest diagnostic ability to discriminate between groups. The combination of ∆Np73α, ∆Np73β and p73 proteoforms seroreactivity were able to improve their individual diagnostic ability. Competitive inhibition experiments further demonstrated the presence of unique specific epitopes in ΔNp73 isoforms not present in p73, with several colorectal patients showing unique and specific seroreactivity to the ΔNp73 proteoforms. Overall, we have increased the complexity of the humoral immune response to the p53-family in cancer patients, showing that the proteoforms derived from the alternative splicing of p73 possess a higher diagnostic ability than the canonical protein, which might be extensive for p53 and p63 proteins.

Abstract
Oral lichen planus (OLP) is a chronic inflammatory disease of unknown etiology with significant impact on patients' quality of life. Malignant transformation into oral squamous cell carcinoma (OSCC) is considered as one of the most serious complications of the disease; nevertheless, controversy still persists. Various factors seem to be involved in the progression of malignant transformation; however, the mechanism of this process is not fully understood yet. Molecular alterations detected in OLP samples might represent useful biomarkers for predicting and monitoring the malignant progression. In this review, we discuss various studies which highlight different molecules as ominous predictors of OLP malignant transformation.

Abstract
Toll-like receptors (TLRs) and nuclear factor-κB (NF-κB) in keratinocytes play an important role in dermatological autoimmune diseases. Tumour suppressor protein p53 regulates TLR expression. The aim of this study was to compare the expression of TLR1-TLR10, p53 and NF-κB in patients with oral lichenoid disease (OLD) with healthy mucosa. Oral mucosal biopsies from 24 patients with OLD and 26 healthy controls (HC) were analysed for the expression of TLR1-TLR10, NF-κB and p53 by immunohistochemistry. The expression of all TLRs was increased in OLD epithelia compared to HC samples and the difference was significant in TLR1, TLR3, TLR4, TLR5, TLR6 and TLR7. In the basement membrane zone, the immunoreactivity of TLR5 was significantly more intense in OLD compared to HC. In the intermediate layer, the immunoreactivity of NF-κB was significantly stronger in OLD, whereas the staining for p53 was more intense in all layers of OLD compared to HC samples. In OLD, a positive correlation between TLR2 and NF-κB in the basal layer and between TLR5, p53 and NF-κB in the intermediate layers was discovered. The expression of TLRs, p53 and NF-κB is increased in OLD, which may play a role in the pathogenesis of this chronic immune-mediated mucosal disease.

Abstract
Context: The malignant transformation potential of oral lichen planus (OLP) and related lesions is a subject of great controversy. Aim: The aim of this study was to compare the expression of proteins related to apoptosis and tumour suppressor gene processes in OLP, oral lichenoid reaction (OLR) and oral lichenoid dysplasia (OLD). Materials and Methods The immunohistochemical study was carried out to investigate the expressions of survivin and p53 in a total of 30 lesional biopsy specimens - 10 cases each of OLP, OLR and OLD. The expression rates were further compared with 10 control specimens of normal oral mucosa (NORM). Results: Immunoreactivity for p53 was seen in 7 cases (70%) of OLD, 4 cases (40%) of OLP and 2 cases (20%) of OLR and none of NORM. We obtained a significant difference (P = 0.01) in mean p53 expression between the different entities. The positive staining rate of survivin was found to be significantly different between OLD (50%), OLP (10%), OLR (0%), and normal mucosa (0%) (P = 0.004). There was a positive correlation between p53 and survivin expression in OLP and OLD using Pearson's correlation coefficient. Conclusion: Lichenoid dysplasia has shown p53 and survivin expression in the range of not OLP, but leukoplakia. On the other hand, OLR seems to be an innocuous lesion. The study results with OLP are inconclusive but points toward a small but important malignant potential in OLP. This kind of comparative study highlights the importance of biopsying OLP and related lesions for proper diagnosis and appropriate management.

Abstract
Oral lichen planus (OLP) is a potentially premalignant condition with unknown pathogenesis. Immune and inflammatory factors are thought to play important roles in the development of OLP, and cytokines, such as interferon (IFN)-γ and tumor necrosis factor (TNF)-α, can act as critical players in the immunopathogenesis of OLP. MicroRNAs (miRNAs) are closely correlated with cytokines in various inflammation-related diseases. In patients with OLP, miRNA-146a and miRNA-155 are increased in peripheral blood mononuclear cells, and numerous miRNAs have been shown to exhibit altered expression profiles in lesions. Although the microRNA-messenger RNA (miRNA-mRNA) network is thought to be involved in the development of OLP, in-depth studies are lacking. Here, we summarize current data on the mechanisms of action of miRNAs regulating typical cytokines in OLP, including interleukin (IL)-10, IL-17, IL-22, IFN-γ, and TNF-α, to study the genetic basis of the pathogenesis of OLP and to provide prospects of therapy.

Abstract
Lichen planus is an inflammatory mucocutaneous disease that can affect the skin, hair, nails, and mucosal surfaces. Mucosal sites of involvement include oral, genital, ocular, otic, esophageal, and, less commonly, bladder, nasal, laryngeal, and anal surfaces. Oral lichen planus is a mucosal variant of lichen planus, which tends to affect women more often than men, with a typically more chronic course and potential for significant morbidity. Treatment can be challenging, and there is potentially a low risk of malignant transformation; however, therapeutic benefits can be obtained with various topical and systemic medications. Clinical monitoring is recommended to ensure symptomatic control. Increasing awareness and recognition of this entity have continued to fuel advances in therapy and in our understanding of the disease.

Abstract
CONTEXT Oral lichen planus (OLP) is a chronic inflammatory mucocutaneous disease with female predominance with the potential for malignant transformation. Human papillomavirus (HPV) is associated with both malignant and benign disease in the head and neck region. AIMS The present study assesses the prevalence of high-risk HPV-16 and HPV-18 in tissue and saliva samples from an Iranian population diagnosed with OLP. SUBJECTS AND METHODS Deoxyribonucleic acid was extracted and investigated using polymerase chain reaction from tissue and saliva samples of the same individuals from 40 OLP cases and saliva samples of 40 healthy controls. STATISTICAL ANALYSIS The prevalence of data was compared using the Chi-square test and inter-group differences were analyzed using Fisher's exact test. RESULTS OLP specimens were HPV-positive in 11 of 40 (27.5%) cases compared with three of 40 (7.5%) saliva specimens, representing a statistically significant difference (P = 0.0367). HPV-16 and HPV-18 were positive in eight of 40 (20%) OLP tissues and three of 40 (7.5%) saliva samples. Five of the 40 healthy saliva samples were positive for HPV-16. In the OLP patients with dysplasia, four of seven tissue samples were HPV-positive; threeof these four were HPV-16- positive in comparision with seven of 33 HPV-positive samples from OLP patients without dysplasia. CONCLUSIONS Biopsies were more accurate than saliva analysis for evaluating HPV prevalence in OLP patients. HPV prevalence was higher in dysplastic than nondysplastic OLP lesions in this Iranian cohort.

Abstract
Oral lichen planus (OLP) is a chronic mucocutaneous inflammatory disease of unknown etiology with a potential for malignant transformation. Little is known about the epidemiology of this condition in the Arab world. A computer-based literature search was conducted using relevant keywords to retrieve studies conducted in Arab world pertaining to OLP, 28 articles were identified initially. After screening for exclusion criteria/retrieving full texts, a total of 15 articles were used for this review. Three studies were cross-sectional and found a prevalence ranging from 0.35% to 1.7%. Studies about risk factors and prognostic markers were conducted in clinical settings, using a case-control design mostly (n = 9), cohort (n = 2), and clinical trial (n = 1). Genetic expressions of various proteins (e.g., BCL family), cultural determinants (Deram chewing), bacterial and viral infections [Helicobacter pylori and Hepatitis C virus (HCV)] were among factors investigated. Evidence extracted from these studies shows a possible link between OLP and Deram use, H. pylori and HCV Infections with a prevalence of the latter infection ranging from 14.7% to 26.3% in patients with OLP. However, paucity of population-based studies limits generalizability of such evidence. Future studies in the Arab world should focus upon surveying the extent of OLP, identifying cultural risk factors, utilization of OLP genetic markers in diagnostic, and prognostic applications.

Abstract
Oral lichen planus (OLP) is a potentially malignant disorder associated with an increased risk for progression to oral squamous cell carcinoma (OSCC). The objective of this study to determine protein expression of cancer stem cell marker CD133 in tissue samples of patients with OLP and evaluate the correlation between CD133 expression and the risk of progression to OSCC. In this longitudinal case-control study, a total of 110 patients with OLP who received a mean follow-up of 56 months were enrolled, including 100 patients who did not progress to OSCC and 10 patients who had progressed to OSCC. CD133 expression was determined using immunohistochemistry in samples from these patients. Analysis of 10 cases of normal oral mucosa and 6 cases of postmalignant OSCC form previously diagnosed OLP was also performed. The results showed that CD133 expression was observed in 29% cases of nonprogressing OLP and in 80% cases of progressing OLP (P = .002). CD133 was not expressed in normal oral mucosa, but it positively expressed in the 100% cases of OSCC. Logistic regression analysis revealed that the risk of malignant progression in the patients with CD133-positive expression was significantly higher than those with CD133 negativity (odds ratio, 9.79; 95% confidence interval, 1.96-48.92; P = .005). Collectively, CD133 expression was significantly associated with malignant progression in a longitudinal series of patients with OLP. Our findings suggested that CD133 may serve as a novel candidate biomarker for risk assessment of malignant potential of OLP.

Abstract
Oral lichen planus (OLP) is a potentially malignant disorder associated with an increased risk of progression to oral squamous cell carcinoma (OSCC). The objective of this study was to determine protein expression of cancer stem cell factor Bmi1 in a longitudinal series of patients with OLP and evaluate the correlation between Bmi1 expression and the risk of progression to OSCC. In a retrospective study, Bmi1 expression was determined using immunohistochemistry in samples from 96 patients with OLP who received a mean follow-up of 54 months, including patients who did not progress to OSCC (n=87) and patients who had progressed to OSCC (n=9). Analysis of 10 cases of normal oral mucosa and 6 cases of postmalignant OSCC form previously diagnosed OLP was also performed. The results showed that Bmi1 expression was observed in 32 (36.8%) of 87 cases of nonprogressing OLP and in 8 (88.9%) of 9 cases of progressing OLP. Bmi1 was not expressed in normal oral mucosa, but it was positively expressed in the 6 (100%) cases of OSCC. Multivariate analysis revealed that the risk of malignant progression in the patients with Bmi1-positive expression was significantly higher than those with Bmi1 negativity (odds ratio, 20.75; 95% confidence interval, 2.21-194.57; P=.008). Collectively, Bmi1 expression was significantly associated with malignant transformation in a large series of patients with OLP who received a longitudinal observation. Our findings suggested that Bmi1 may serve as a useful marker for the identification of a high risk of malignant progression of OLP.

Oral lichen planus as a preneoplastic inflammatory model. J Biomed Biotechnol 2012; 2012:759626. [PMID: 22675259 PMCID: PMC3362930 DOI: 10.1155/2012/759626] [Citation(s) in RCA: 65] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2012] [Accepted: 03/16/2012] [Indexed: 01/24/2023] Open
Abstract
Oral lichen planus (OLP) is a chronic oral inflammatory disease of unknown etiology. According to reports, 1-2% of OLP patients develop oral squamous cell carcinoma (OSCC) in the long run. While World Health Organization (WHO) classifies OLP as “a potentially malignant disorder,” it is still a matter of debate which mechanisms drive OLP to such a condition. The current hypothesis connecting OLP and OSCC is that chronic inflammation results in crucial DNA damage which over time results in cancer development. Initial studies investigating the OLP and OSCC link were mainly retrospective clinical studies. Over the past years, several amount of information has accumulated, mainly from molecular studies on the OLP malignant potential. This article is a critical review of whether OLP has a malignant potential and, therefore, represents a model of preneoplastic inflammation.
