Luo X, Xie D, Wu T, Xu W, Meng Q, Cao K, Hu J. Evaluation of the protective roles of alpha-lipoic acid supplementation on nanomaterial-induced toxicity: A meta-analysis of in vitro and in vivo studies. Front Nutr 2022; 9:991524. [PMID: 36147302 PMCID: PMC9486203 DOI: 10.3389/fnut.2022.991524] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 08/17/2022] [Indexed: 01/02/2023] Open
Abstract
Extensive exposure to nanomaterials causes oxidative stress and inflammation in various organs and leads to an increased risk of adverse health outcomes; therefore, how to prevent the toxic effects are of great concern to human. Alpha-lipoic acid (ALA) has anti-oxidant and anti-inflammatory activities, suggesting it may be effective to prevent nanomaterial-induced toxicity. However, the results obtained in individual studies remained controversial. We aimed to comprehensively evaluate the effects of ALA supplementation on nanomaterial-induced toxicity by performing a meta-analysis. Databases of PubMed, EMBASE, and Cochrane Library were searched up to May 2022. STATA 15.0 software was used for statistical analysis. Twelve studies were included. Meta-analysis of eight in vivo studies showed ALA supplementation could exert significant effects on nanomaterial-induced oxidative stress (by reducing MDA, ROS and increasing GSH, CAT, GPx, and SOD), inflammation (by downregulating NO, IgG, TNF-α, IL-6, and CRP), apoptosis (by activation of pro-apoptotic caspase-3), DNA damage (by a reduction in the tail length) and organ damage (by a decrease in the liver biomarker ALT and increases in brain neuron biomarker AChE and heart biomarker CPK). Pooled analysis of four in vitro studies indicated ALA intervention increased cell viability, decreased ROS levels, inhibited cell apoptosis and chelated metal ions. Subgroup analyses revealed changing the levels of GSH, IL-6, and metal ions were the main protective mechanisms of ALA supplementation because they were not changed by any subgroup factors. In conclusion, ALA supplementation may represent a potential strategy for the prevention of the toxicity induced by nanomaterials.

Abstract
Ferroptosis resistance is an important mechanism of tumor progression. Interleukin-6 (IL-6) is a representative inflammatory cytokine during chronic inflammation; however, our current understanding of its regulatory role of ferroptosis during carcinogenesis of head and neck squamous cell carcinoma is limited. Chromatin immunoprecipitation and functional observations were performed to investigate xCT-regulatory function of IL-6. We observed a gradual increase in lipid peroxide 4-hydroxynonenal and IL-6 levels during progression from normal oral mucosa to leukoplakia and HNSCC. Meanwhile, the expression of xCT, a key amino acid antiporter assisting ferroptosis resistance, was correlated with IL-6 levels. The upregulated expression of xCT in HNSCC is associated with poor prognosis. Silencing of xCT inhibited HNSCC cell proliferation in vitro and tumor growth in vivo, inducing ferroptosis. Mechanistically, IL-6 transcriptionally activates xCT expression through the JAK2/STAT3 pathway. Furthermore, IL-6 reversed ferroptosis and growth suppression that was induced by xCT knockdown or ferroptosis inducer erastin. Our results demonstrate the critical role of IL-6-induced ferroptosis resistance during HNSCC carcinogenesis. The IL-6/STAT3/xCT axis acts as a novel mechanism driving tumor progression and thus may potentially be utilized as a target for tumor prevention and therapy.

Abstract
Areca nut is a highly addictive substance with carcinogenic properties and causes many harmful effects to the human body. Alkaloids are the major chemicals found in areca nut, and their mechanism of action has been studied for several years. About 600 million people around the world use areca nut, and its usage is higher in Asian countries. Areca nut chewers get used to the habit mainly due to social influence, stress, or lack of awareness. Some studies have reported a dependence syndrome related to areca nut chewing. Even though there are many ongoing research studies regarding tobacco addiction, less concern has been given to the areca nut addiction. There are only few studies related to areca nut cessation, and even those few cessation programs are mainly designed using tobacco cessation methodology. Sociocultural influence, behavioral factors, and accessibility are the main barriers to cessation. Behavior changing interventions proved to be more effective in areca nut cessation, but recently studies on pharmacological therapies are also emerging.

Abstract
Oral submucous fibrosis (OSF) is a collagen deposition disorder that affects a patient’s oral function and quality of life. It may also potentially transform into malignancy. This review summarizes the risk factors, pathogenic mechanisms, and treatments of OSF based on clinical and bio-molecular evidence. Betel nut chewing is a major risk factor that causes OSF in Asia. However, no direct evidence of arecoline-induced carcinogenesis has been found in animal models. Despite identification of numerous biomarkers of OSF lesions and conducting trials with different drug combinations, clinicians still adopt conservative treatments that primarily focus on relieving the symptoms of OSF. Treatments focus on reducing inflammation and improving mouth opening to improve a patient’s quality of life. In conclusion, high-quality clinical studies are needed to aid clinicians in developing and applying molecular biomarkers as well as standard treatment guidelines.

Abstract
Areca nut has been evaluated as a group I carcinogen to humans. However, the exact compounds of areca nut causing oral cancer remain unproven. Previous findings from our lab revealed that arecoline N-oxide (ANO), a metabolite of arecoline, exhibits an oral fibrotic effect in immune-deficient NOD/SCID mice. The aim of this study is to investigate the oral potentially malignant disorders (OPMD) inductive activity between areca-alkaloid arecoline and its metabolite ANO in C57BL/6 mice. Our findings show that ANO showed higher activity in inducing hyperplasia with leukoplakia and collagen deposition in C57BL/6 mice compared with the arecoline treated groups. Importantly, immunohistochemical studies showed significant upregulation of NOTCH1, HES1, FAT1, PCNA, and Ki67 expressions in the pathological hyperplastic part. In addition, in vitro studies showed that upregulation of NOTCH1 and FAT1 expressions in ANO treated HGF-1 and DOK cell models. We found that NOTCH1 regulates TP53 expression from NOTCH1 knockdown oral cancer cells. The DNA damage was significantly increased after arecoline and ANO treatment. Further, we found that arecoline-induced H2AX expression was regulated by FMO3. Altogether, our findings show that ANO exhibited higher toxicity in OPMD activity and play a significant role in the induction of areca nut mediated oral tumorigenesis.

Abstract
Aims: Arecoline, a predominant alkaloid present in arecanut, has been implicated in the pathogenesis of several oral diseases because of its mutagenic and carcinogenic potential. The response of cultured cells to arecoline is highly dependent on its concentration; arecoline stimulates cultured cells above 0.1 μg/ml and is cytotoxic above 10 μg/ ml. Although this alkaloid seems important for areca nut induced oral diseases and carcinogenesis, little is known of the levels achieved before, during and after chewing. Also, it is prudent to understand its effects in arecanut chewers for a comprehensive understanding of its pathogenesis. Accordingly, the present study quantified the salivary arecoline levels in arecanut chewers. Materials and Methods: The study participants were divided into Study Group A & B and Control Group C; unstimulated whole saliva was collected by spitting method for a period of 5 min. Then, participants in Group A and C chewed 0.5 g of areca nut without any other additives while in Group B were asked to chew 0.5 g of inert rubber base impression material. Stimulated whole saliva from all three groups was collected into graduated tubes during chewing at time intervals of 1, 3, 5, 10, 15, 20 and 25 min. Then, all participants were asked to remove nut particles or inert rubber base material from the mouth, and saliva samples were collected further up to 20 min, changing tubes at 5 min interval. Salivary arecoline was quantitated by HPLC-MS. The tabulation and descriptive statistics of the study were carried out. Results: In the present study, baseline levels of arecoline were zero in all three groups, whereas mean salivary arecoline levels during chewing were 76.93 ng/ml, 129.83 ng/ml and 64.83 ng/ml and after chewing were 196.17 ng/ml, 321.12 ng/ml and 43.75 ng/ml in Groups A, B and Control respectively, which were significantly higher than reported threshold levels. Conclusions: The data from this study reveals that a significant amount of arecoline would be trapped in oral cavity, or being re-circulated between blood and saliva might have resulted in surprisingly high levels of arecoline even 10 mins after chewing in both groups after which the levels started declining. The higher levels of salivary arecoline achieved during and after chewing are enough to cause cytotoxic and genotoxic effects on oral tissues over a period of time in chronic chewers. The great differences in salivary arecoline levels achieved during chewing, may contribute to the variable response to areca nut seen in communities where this habit is widespread. Areca nut users have persistent background salivary arecoline levels long after chewing, whereas concentrations achieved are highly variable and consistent with a role in oral pre-malignancy and malignancy..

Abstract
Oral submucous fibrosis (OSF) has been indicated as one of the oral potentially malignant disorders. Epidemiological studies have attributed this pathological fibrosis to the habit of areca nuts chewing, which causes chronic inflammation and persistent activation of myofibroblasts in the oral cavity. Hence, it is crucial to find an effective intervention to ameliorate inflammation in order to prevent the malignant progression of OSF. In this study, we assessed the anti-inflammatory effect of the immunomodulatory protein, GMI, extracted from Ganoderma microsporum on the expression proinflammatory cytokines and the myofibroblast characteristics in human fibrotic buccal mucosal fibroblasts (fBMFs). Our results demonstrated that the expression level of interleukin (IL)-6 and IL-8 were decreased after exposure of GMI and the myofibroblast activities, including collagen gel contraction, migration, invasion, and wound healing abilities were inhibited as well. Furthermore, we confirmed these findings in the arecoline-stimulated BMFs. Consistent with the above findings, the expression of the myofibroblast marker α-smooth muscle actin and other fibrogenic markers, such as type I collagen, fibronectin, and vimentin in fBMFs were all reduced in a dose-dependent manner. Collectively, our data suggested that GMI suppressed the proinflammatory cytokines and myofibroblast features in fBMFs, and could serve as a promising and natural antifibrosis agent.

Abstract
The metabolites of environmental chemicals play key roles in carcinogenesis. Areca nut is strongly associated with the development of oral potentially malignant disorders (OPMD) or cancer. The main alkaloid in the areca nut is arecoline, which is highly cytotoxic and genotoxic. Arecoline N-oxide, a metabolite of areca nut alkaloids, which has been identified in animal urine, has been shown to induce mutagenicity in bacteria. In this study, it was found that its protein adduct could be detected in oral keratinocytes treated with areca nut extract. Increased collagen expression and severity of squamous hyperplasia were observed in arecoline N-oxide treated mice. In cultured oral fibroblasts, arecoline N-oxide showed stronger effects on the increase of fibrotic related genes including TGF-beta1, S100A4, MMP-9, IL-6, and fibronectin and a decrease of E-cadherin as compared with arecoline. Finally, arecoline N-oxide stimulation effectively increased the DNA damage marker, gamma-H2A.X, both in vitro and in vivo. Taken together, these results indicate that arecoline N-oxide shows a high potential for the induction of OPMD.

Abstract
Molecular crosstalk between cancer cells and fibroblasts has been an emerging hot issue in understanding carcinogenesis. As oral submucous fibrosis (OSF) is an inflammatory fibrotic disease that can potentially transform into squamous cell carcinoma, OSF has been considered to be an appropriate model for studying the role of fibroblasts during early stage carcinogenesis. In this sense, this study aims at investigating whether areca nut (AN)‐exposed fibroblasts cause DNA damage of epithelial cells. For this study, immortalized hNOF (hTERT‐hNOF) was used. We found that the levels of GRO‐α, IL‐6 and IL‐8 increased in AN‐exposed fibroblasts. Cytokine secretion was reduced by antioxidants in AN‐exposed fibroblasts. Increase in DNA double strand breaks (DSB) and 8‐oxoG FITC‐conjugate was observed in immortalized human oral keratinocytes (IHOK) after the treatment of cytokines or a conditioned medium derived from AN‐exposed fibroblasts. Cytokine expression and DNA damage were also detected in OSF tissues. The DNA damage was reduced by neutralizing cytokines or antioxidant treatment. Generation of reactive oxygen species (ROS) and DNA damage response, triggered by cytokines, were abolished when NADPH oxidase (NOX) 1 and 4 were silenced in IHOK, indicating that cytokine‐triggered DNA damage was caused by ROS generation through NOX1 and NOX4. Taken together, this study provided strong evidence that blocking ROS generation might be a rewarding approach for cancer prevention and intervention in OSF. What's new? Fibroblasts in the tumor microenvironment influence tumor initiation and growth and are of particular interest in oral submucous fibrosis (OSF), a progressive fibrotic disease of malignant potential. This study shows that the release of tumor‐promoting cytokines by fibroblasts exposed to areca nut, the primary cause of OSF, induce DNA damage in oral keratinocytes. The findings suggest that fibroblasts indirectly promote epithelial transformation in OSF by secreting cytokines, whereby DNA damage of epithelial cells is inflicted by reactive oxygen species generated via NADPH oxidases. These insights could inform the development of new therapeutic approaches for OSF.

Abstract
Oral submucous fibrosis (OSF) is a potentially malignant disease predominantly found in Asian people. The areca nut has been implicated in this disease. Arecoline, one of the areca alkaloids, induces epithelial-mesenchymal transition (EMT)-related factors in primary human buccal mucosal fibroblasts. Yet, the mechanisms of the underlying arecoline-induced EMT in OSF remain unknown. In the present study, we aimed to investigate the role of microRNAs (miRNAs) in arecoline-induced EMT in HaCaT cells. We found that miR-203 was significantly downregulated in OSF tissues compared to that in normal buccal mucosa tissues, and that miR-203 negatively regulated secreted frizzled-related protein 4 (SFRP4) and positively regulated transmembrane-4 L six family member 1 (TM4SF1). We observed that upregulation of miR-203 significantly decreased the cell proliferation of HaCaT cells, and significantly upregulated the expression of cytokeratin 19 (CK19) and E-cadherin proteins, whereas it significantly downregulated the expression of N-cadherin and vimentin compared to these levels in the vehicle control cells. Thus, we provide evidence to illustrate that miR-203 plays a role in the pathogenesis of OSF, which may be a target for OSF management.

Knockdown of S100A4 impairs arecoline-induced invasiveness of oral squamous cell carcinomas. Oral Oncol 2015; 51:690-7. [PMID: 25912158 DOI: 10.1016/j.oraloncology.2015.04.003] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2014] [Revised: 02/02/2015] [Accepted: 04/04/2015] [Indexed: 12/25/2022]
Abstract
OBJECTIVES Metastasis is the most common cause of oral squamous cell carcinoma (OSCC)-related death. The physiological function of S100A4 in the pathogenesis of areca quid chewing-associated OSCC has not been uncovered. METHOD OSCC tissues from areca quid chewers were analyzed by immunohistochemistry for S100A4 expression. The functions of S100A4 in invasiveness of arecoline-treated oral epithelial (OE) cells were determined by loss function approaches. RESULTS Expression of S100A4 was positively correlated with clinical grading and lymph node metastasis of OSCC. Upregulated S100A4 is correlated with poor survival outcome of OSCC patients. Arecoline led to dose-dependent elevation of S100A4 expression in oral epithelial (OE) cells. Down-regulation of S100A4 significantly reversed arecoline-induced oncogenecity in OE cells. The additions of pharmacological agents LY294002, SP600125, and CAY10585 were found to inhibit arecoline-induced S100A4 expression in OE cells. CONCLUSION Arecoline-induced S100A4 expression was down-regulated by LY294002, SP600125, or CAY10585 treatment. Targeting S100A4 might offer a new strategy for the treatment of OSCC patients with metastasis.

Abstract
Oral submucous fibrosis (OSF) is a premalignant condition caused by betel chewing. It is very common in Southeast Asia but has started to spread to Europe and North America. OSF can lead to squamous cell carcinoma, a risk that is further increased by concomitant tobacco consumption. OSF is a diagnosis based on clinical symptoms and confirmation by histopathology. Hypovascularity leading to blanching of the oral mucosa, staining of teeth and gingiva, and trismus are major symptoms. Major constituents of betel quid are arecoline from betel nuts and copper, which are responsible for fibroblast dysfunction and fibrosis. A variety of extracellular and intracellular signaling pathways might be involved. Treatment of OSF is difficult, as not many large, randomized controlled trials have been conducted. The principal actions of drug therapy include antifibrotic, anti-inflammatory, and antioxygen radical mechanisms. Potential new drugs are on the horizon. Surgery may be necessary in advanced cases of trismus. Prevention is most important, as no healing can be achieved with available treatments.

Abstract
BACKGROUND Areca nut chewing is associated with oral submucous fibrosis (OSF). Raised vascular basic fibroblast growth factor may induce fibrosis. Arecoline is a muscarinic alkaloid in areca nut, which we earlier reported causes injury and necrosis of human endothelium. MATERIALS AND METHODS Human umbilical vein endothelial cells were exposed to arecoline with or without tumor necrosis factor-α, and separately to acetylcholine, muscarine, or nicotine. Protein levels of basic fibroblast growth factor, as well as the inflammatory cytokines: granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor, and Interleukins-6, 1-α and 1-β, were determined by enzyme-linked immunosorbent assay. mRNA levels were established by real-time reverse transcription polymerase chain reaction. RESULTS Basic fibroblast growth factor was released into the culture medium at arecoline levels causing necrosis (P < 0.05). This contrasted with an opposite effect of arecoline on levels of the inflammatory cytokines (P < 0.05). Tumor necrosis factor-α increased IL-6 and granulocyte-macrophage colony stimulated factor, but arecoline reduced this stimulated expression (P < 0.05). Arecoline had no effect on mRNA for basic fibroblast growth factor, although there was reduced mRNA for the separate inflammatory cytokines studied. The effect of acetylcholine, muscarine, and nicotine was minimal and dissimilar to that of arecoline. CONCLUSIONS Data raise the possibility that arecoline-induced, vascular basic fibroblast growth factor contributes to OSF, by combining increased growth factor expression with endothelial necrosis, and thus driving fibroblast proliferation.

Abstract
BACKGROUND Oral submucous fibrosis (OSF) is regarded as a pre-cancerous condition with fibrosis in oral subepithelial connective tissue. Hypoxia-inducible factor (HIF)-1α regulates a wide variety of profibrogenic genes, which are closely associated with tissue fibrosis. The aim of this study was to compare HIF-1α expression in normal buccal mucosa tissues and OSF specimens and further explore the potential mechanisms that may lead to the induction of HIF-1α expression. METHOD Twenty-five OSF specimens and six normal buccal mucosa were examined by immunohistochemistry. The expression of HIF-1α from fibroblasts cultured from OSF and normal buccal mucosa was measured by Western blot. Arecoline, a major areca nut alkaloid, was challenged to normal buccal mucosa fibroblasts (BMFs) to elucidate whether HIF-1α expression could affect by arecoline. In addition, the effects of arecoline on plasminogen activator inhibitor (PAI)-1 expression were evaluated in environmental hypoxia. RESULTS HIF-1α expression was significantly higher in OSF specimens and expressed mainly by fibroblasts, epithelial cells, and inflammatory cells. Fibroblasts derived from OSF were found to exhibit higher HIF-1α protein expression than BMFs (P < 0.05). Arecoline was found to upregulate HIF-1α protein in a dose-dependent manner (P < 0.05). Hypoxia increased arecoline-induced PAI-1 protein expression than normoxic conditions (P < 0.05). CONCLUSION These results suggest that HIF-1α expression is significantly upregulated in OSF tissues from areca quid chewers, implying a potential role as a biomarker for local tissue hypoxia. The activation of HIF-1α may promote fibrogenesis by an increase of PAI-1 expression and a subsequent elevation of extracellular matrix production in oral submucosa leading to fibrosis.

Abstract
Background/purpose Oral submucous fibrosis (OSF) is a potentially malignant disorder of oral squamous cell carcinoma (SCC). In this study, we obtained the genetic expression signatures of OSF and SCC by microarray analysis. Materials and methods Five patients with clinically evident OSF, five patients with SCC who also had existing OSF, and four normal volunteers who did not have a history of chewing betel quids were recruited. Biopsy specimens were obtained with an approved Institutional Review Board protocol. Total RNA from OSF or SCC was isolated and hybridized to a Human Oligo 1A (V2) Microarray (G4110B) chip against normal control RNA that was pooled from the four healthy volunteers. Results We found similar, but distinct genetic expression signatures for OSF and SCC. At the hierarchical clustering analysis, 24 known genes (23 upregulated and 1 downregulated) in OSF were differentially expressed consistently in all participants. Among the genes, XRCC5 was cloned and transfected into oral cancer GNM cells. The results demonstrated that the overexpression of XRCC5 increased the resistance of GNM cells to low-density X-ray irradiation and promoted the cell growth rate. Conclusion The distinct but similar genetic expression signatures seen in OSF and SCC suggested that this expression may be used as a supplemental diagnostic tool in pathology practice. This preliminary study showed that the XRCC5 gene promoted GNM cell growth and conferred resistance to low-density X-ray irradiation. Further studies on the effect of XRCC5 in oral cancer cells are in progress.

Abstract
Background S100A4, a member of the calcium-binding proteins, is dramatically elevated in a variety of fibrotic diseases. Areca quid chewing is the most important etiological factor in the pathogenesis of oral submucous fibrosis (OSF). OSF has been considered as a pre-cancerous condition of oral mucosa. The aim of this study was to determine the critical role of S100A4 expression in the pathogenesis of OSF both in vitro and in vivo. Methodology/Principal Finding Thirty OSF tissues from areca quid chewers and ten normal buccal mucosa samples without areca quid chewing were analyzed by using immunohistochemistry for S100A4 expression in vivo. Collagen gel contraction capability and expression of tissue inhibitor of metalloproteinases 1 (TIMP1)/MMP9 in arecoline-stimulated BMFs with S100A4 knockdown was presented in vitro. Initially, S100A4 expression was higher in areca quid chewing-associated OSF specimens than normal buccal mucosa specimens (p = 0.001). Arecoline, a major areca nut alkaloid, led to dose- and time-dependent elevation of S100A4 expression in normal buccal mucosa fibroblasts BMFs (p<0.05). The additions of pharmacological agents rapamycin (mTOR inhibitor), PD98059 (ERK inhibitor), and Bay117082 (NF-κB inhibitor) were found to inhibit arecoline-induced S100A4 expression (p<0.05) in BMFs. Down-regulation of S100A4 by lentiviral infection significantly reversed arecoline-induced collagen gel contraction and TIMP1/MMP9 expression. Conclusion/Significance These results suggest that S100A4 expression is significantly up-regulated in OSF specimens. Arecoline-induced S100A4 expression was down-regulated by rapamycin, PD98059, and Bay117082. Targeting S100A4 might be a potential therapeutic target for OSF through TIMP1/MMP9 down-regulation.

Abstract
BACKGROUND The purpose of this study was to compare the major thrombin receptor protease-activated receptor-1 (PAR-1) expression in normal human buccal mucosa and oral submucous fibrosis (OSF) specimens and further explore the potential mechanisms that may lead to induce PAR-1 expression. METHODS Thirty OSF and 10 normal buccal mucosa specimens were examined by immunohistochemistry. Buccal mucosal fibroblasts (BMFs) were challenged with arecoline by using Western blot analysis. N-acetyl-L-cysteine (NAC), LY294002, herbimycin A, NS-398, and PD98059 were added to find the possible regulatory mechanisms. RESULTS PAR-1 expression was significantly higher in OSF specimens (p < .05). Arecoline was found to elevate PAR-1 expression in a dose-dependent and time-dependent manner (p < .05). The addition of NAC, LY294002, herbimycin A, NS398, and PD98059 markedly inhibited the arecoline-induced PAR-1 expression (p < .05). CONCLUSION PAR-1 expression is significantly upregulated in areca quid chewing-associated OSF. Arecoline-induced PAR-1 expression was downregulated by NAC, LY294002, herbimycin A, NS398, and PD98059.

Abstract
Betel nut (BN), betel quid (BQ) and products derived from them are widely used as a socially endorsed masticatory product. The addictive nature of BN/BQ has resulted in its widespread usage making it the fourth most abused substance by humans. Progressively, several additives, including chewing tobacco, got added to simple BN preparations. This addictive practice has been shown to have strong etiological correlation with human susceptibility to cancer, particularly oral and oropharyngeal cancers. The PUBMED database was searched to retrieve all relevant published studies in English on BN and BQ, and its association with oral and oropharyngeal cancers. Only complete studies directly dealing with BN/BQ induced carcinogenesis using statistically valid and acceptable sample size were analyzed. Additional relevant information available from other sources was also considered. This systematic review attempts to put in perspective the consequences of this widespread habit of BN/BQ mastication, practiced by approximately 10% of the world population, on oral cancer with a clinical perspective. BN/BQ mastication seems to be significantly associated with susceptibility to oral and oropharyngeal cancers. Addition of tobacco to BN has been found to only marginally increase the cancer risk. Despite the widespread usage of BN/BQ and its strong association with human susceptibility to cancer, no serious strategy seems to exist to control this habit. The review, therefore, also looks at various preventive efforts being made by governments and highlights the multifaceted intervention strategies required to mitigate and/or control the habit of BN/BQ mastication.

Abstract
Cystatin C is a 13kDa non-glycosylated basic protein belonging to cystatin family. It is consistently and dramatically upregulated in a variety of fibrotic diseases. The aim of this study was to compare cystatin C expression in normal human buccal mucosa and oral submucous fibrosis (OSF) specimens and further explore the potential mechanism that may lead to induction of cystatin C expression. Twenty-five OSF specimens and six of normal buccal mucosa were examined by immunohistochemistry. The activity of cystatin C from fibroblasts cultured from OSF and normal buccal mucosa were evaluated by using reverse-transcriptase polymerase chain reaction and enzyme-linked immunosorbent assay. Furthermore, the effect of arecoline, the major areca nut alkaloid, was explored. Cystatin C expression was significantly higher in OSF specimens (p<0.05) and expressed mainly by fibroblasts, endothelial cells, and inflammatory cells. OSF demonstrated significantly higher cystatin C expression than normal buccal mucosa fibroblasts both in mRNA and protein levels (p<0.05). In addition, arecoline was also found to elevate cystatin C mRNA and protein expression in a dose-dependent manner (p<0.05). Taken together, the data demonstrate that cystatin C expression is significantly upregulated in OSF from areca quid chewers and arecoline may be responsible for the enhanced cystatin C expression in vivo.

Abstract
To investigate whether angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism is related to the risk of oral precancerous lesions (OPL) in Taiwanese subjects who chew betel quid, a total of 61 betel quid chewers having OPL were compared with 61 asymptomatic betel quid chewers matched for betel quid chewing duration and dosage. The frequency of homozygote for ACE D variant is significantly higher in the case subjects than that of the controls (44.3 vs 24.6%; P=0.0108). The adjusted odds ratio of the D homozygous for the risk of OPL is 8.10 (95% confidence interval (CI)=2.04–32.19, P=0.003). In the allelic base analysis, the D allele is also significantly associated with higher risk of OPL. When grouping the study subjects by smoking status, the association between ACE I/D polymorphism and risk of OPL was only observed in nonsmokers. Our results support the theory that genetic factors may contribute to the susceptibility of OPL and suggest that smoking and genetic factors may be differently involved in the development of OPL.

Abstract
Insulin-like growth factor-1 (IGF-1) is a member of a family of two interacting polypeptide hormone ligands with close homology to proinsulin. IGF-1 can influence mesenchymal cell migration, proliferation, and extracellular matrix deposition, thus implicating it in the progression of fibrotic disorders. Currently, there is limited information about the regulation of IGF-1 expression in areca quid-associated oral submucous fibrosis (OSF). The aim of this study was to compare IGF-1 expression in normal human buccal mucosa and OSF specimens and further explore the potential mechanism that may lead to induce IGF-1 expression. Twenty OSF specimens and 10 normal buccal mucosa were examined by immunohistochemistry. The activity of IGF-1 from cells cultured from OSF and normal buccal mucosa were by using reverse-transcriptase polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA). Furthermore, the effect of arecoline, the major areca nut alkaloid, was added to explore the potential mechanism that may lead to induce IGF-1 expression. IGF-1 expression was significantly higher in OSF specimens (p<0.05) and expressed mainly by fibroblasts, endothelial cells, and inflammatory cells. OSF demonstrated significantly higher IGF-1 protein expression than normal buccal mucosa fibroblast (BMF) both in mRNA and protein levels (p<0.05). In addition, arecoline was also found to elevate IGF-1 mRNA and protein expression in a dose-dependent manner (p<0.05). Taken together, the data presented here demonstrated that IGF-1 expression is significantly upregulated in OSF from areca quid chewers and arecoline may be responsible for the enhanced IGF-1 expression in vivo.
