Abstract
Endometrial cancer (EC) constitutes more than half of all genital cancers in women, with an increasing incidence in different countries. Natural killer cells (NK cells) are kinds of innate immune cells that are controlled by sets of receptors, such as killer cell Ig-like receptors (KIRs), which can inhibit or activate NK cells. In this study, we evaluated the diversity and genetic association of KIRs in confirmed cases of endometrial cancer compared to healthy controls. A total of 151 women with EC and 167 age/race-matched healthy controls were analyzed for KIR genes. Demographic and histopathologic data were gathered in questionnaires, and 16 KIR genes along with two variants of KIR2DS4 (KIR2DS4fl and KIR2DS4del), were genotyped by usingsequence specific primers-polymerase chain reaction (SSP-PCR) method. A comparison between cases and controls revealed that although there were not any significant differences in A haplotype associated genes and also the variants of KIR2DS4 (p >0.05), B haplotype associated genes such as KIR2DS2 and KIR2DL2 decreased significantly in EC patients in comparison with healthy controls (p=0.03 and p=0.01, respectively). Furthermore, we found that EC mostly developed in cases with the AA genotype; however, the carriers of Bx and C4T4 genotypes were less frequent in patients with EC. Our results revealed that KIR2DS2 and KIR2DL2, along with Bx and C4T4 genotypes, have a protective impact against developing endometrial cancer in Iranians.

Abstract
Aim Long noncoding RNAs (lncRNA) ANRIL and its genetic polymorphisms are shown to be associated with the risk of several cancers. However, the single nucleotide polymorphisms (SNPs) of lncRNA ANRIL are not thoroughly assessed in oral squamous cell carcinoma (OSCC) which is the most prevalent cancer in the head and neck area. Thus, this study aimed to assess the association of SNP of lncRNA ANRIL rs4977574 in patients with OSCC. Methods and Materials 106 blood samples from the patients with OSCC were obtained with a gender- and age-matched control group to evaluate the SNP of rs4977574 of lncRNA ANRIL. The DNA was extracted using the salt-out technique and DNA genotyping was undertaken using specific primer pairs in the tetra-primer ARMS-PCR technique. Eventually, the frequency of wild-type (A) and the mutated allele (G), as well as the genotypes were estimated between the groups of patients with OSCC and healthy individuals. Results The results of our study indicated no statistically significant difference in the frequency of rs4977574 A/G of lncRNA ANRIL among the patients with OSCC and healthy individuals (p > 0.05). Likewise, no significant difference was found in the genotypes' frequencies (p > 0.05). Nevertheless, the marked association of GG with smaller tumor size and the high level of differentiation of OSCC cells in the presence of AA or AG genotypes were interesting outcomes of this study (p < 0.05). Similarly, all the genotypes AA, AG, and GG were correlated with the site of the occurrence of OSCC. Furthermore, the association of the genotypes with the lymph node metastasis and the tumors stage was not found to be significant (p > 0.05). Conclusions The results of our study indicate that rs4977574 A/G and its genotypes do not have any direct correlation with the presence of OSCC; however, its association with the smaller tumor size and the level of the cancer cells differentiation could imply its possible indirect role.

Abstract
Measles is an acute, highly contagious disease with a high mortality rate in children. Although vaccination has reduced measles incidence, outbreaks still occur. Therefore, in this study, we aimed to investigate the frequency of antimeasles immunoglobulin G (IgG) antibody (Ab) among students at Shiraz University of Medical Sciences (SUMS). Four hundred fifty SUMS students were enrolled in this cross-sectional study. Information on demographics and measles vaccination history was collected using a questionnaire. Participants were divided into two groups, including A and B, according to routine doses of measles vaccine and the national measles/rubella immunization program. The antimeasles IgG Abs were tested using a commercial Enzyme-Linked Immunosorbent Assay Kit. Participants ranged in age from 18 to 48 years, with a mean age of 22.2 (±4.3). Fifty percent of the subjects were male. Our results showed that 63.6% of the cases were positive for antimeasles IgG Abs. The seroprevalence of IgG Abs between groups A and B did not differ significantly (p = 0.612). There was also no significant correlation between the seroprevalence of antimeasles IgG Abs and the age (p = 0.43) or sex (p = 0.24) of the subjects. The results showed that the frequency of antimeasles IgG Abs is lower than required to prevent the measles virus from circulating. Therefore, a booster vaccination may be necessary.

Abstract
Background & objectives To examine β-D-mannuronic acid (M2000) effects on L-selectin shedding and leucocyte function-associated antigen-1 (LFA-1) expression as mechanisms of action of this drug in patients with ankylosing spondylitis (AS). Methods To investigate the molecular consequences of β-D-mannuronic acid on L-selectin shedding, flow cytometry method was used. Furthermore, the effect of it on LFA-1 gene expression was analyzed by using quantitative real time (qRT)-PCR technique. Results The LFA-1 expression in patients with AS was higher than controls (P=0.046). The LFA-1 expression after 12 wk therapy with β-D-mannuronic acid was meaningfully decreased (P=0.01). After 12 wk treatment with β-D-mannuronic acid, the frequency of CD62L-expressing CD4+ T cells in patients with AS, was not considerably altered, compared to the patients before therapy (P=0.5). Furthermore, after 12 wk therapy with β-D-mannuronic acid, L-selectin expression levels on CD4+ T-cells in patients with AS, were not remarkably changed, compared to the expression levels of these in patients before treatment (P=0.2). Interpretation & conclusions The results of this study for the first time showed that β-D-mannuronic acid can affect events of adhesion cascade in patients with AS. Moreover, β-D-mannuronic acid presented as an acceptable benefit to AS patients and could aid in the process of disease management.

Abstract
Interleukin-38 (IL-38) is the most recent member of the IL-1 family that acts as a natural inflammatory inhibitor by binding to cognate receptors, particularly the IL-36 receptor. In vitro, animal and human studies on autoimmune, metabolic, cardiovascular and allergic diseases, as well sepsis and respiratory viral infections, have shown that IL-38 exerts an anti-inflammatory activity by modulating the generation and function of inflammatory cytokines (e.g. IL-6, IL-8, IL-17 and IL-36) and regulating dendritic cells, M2 macrophages and regulatory T cells (Tregs). Accordingly, IL-38 may possess therapeutic potential for these types of diseases. IL-38 down-regulates CCR3+ eosinophil cells, CRTH2+ Th2 cells, Th17 cells, and innate lymphoid type 2 cells (ILC2), but up-regulates Tregs, and this has influenced the design of immunotherapeutic strategies based on regulatory cells/cytokines for allergic asthma in future studies. In auto-inflammatory diseases, IL-38 alleviates skin inflammation by regulating γδ T cells and limiting the production of IL-17. Due to its ability to suppress IL-1β, IL-6 and IL-36, this cytokine could reduce COVID-19 severity, and might be employed as a therapeutic tool. IL-38 may also influence host immunity and/or the components of the cancer microenvironment, and has been shown to improve the outcome of colorectal cancer, and may participate in tumour progression in lung cancer possibly by modulating CD8 tumour infiltrating T cells and PD-L1 expression. In this review, we first briefly present the biological and immunological functions of IL-38, and then discuss the important roles of IL-38 in various types of diseases, and finally highlight its use in therapeutic strategies.

Abstract
The initiation and progression of bladder cancer (BC), is dependent on its tumor microenvironment (TME). On the other hand, cancer cells shape and train TME to support their development, respond to treatment and migration in an organism. Immune cells exert key roles in the BC microenvironment and have complex interactions with BC cells. These complicated interplays result in metabolic competition in the TME leading to nutrient deprivation, acidosis, hypoxia and metabolite accumulation, which impair immune cell function. Recent studies have demonstrated that immune cells functions are closely correlated with their metabolism. Immunometabolism describes the functional metabolic alterations that take place within immune cells and the role of these cells in directing metabolism and immune response in tissues or diseases such as cancer. Some molecules and their metabolites in the TME including glucose, fatty acids and amino acids can regulate the phenotype, function and metabolism of immune cells. Hence, here we describe some recent advances in immunometabolism and relate them to BC progression. A profound understanding of the metabolic reprogramming of BC cells and immune cells in the TME will offer novel opportunities for targeted therapies in future.

Abstract
Abstract
Background
Meningiomas are one of the most common tumors of the brain and central nervous system. The key role of endocan in predicting tumor growth and prognosis has been shown for several types of cancers; however, this role in meningiomas has not been evaluated. In the current study, we investigated the relationship between endocan serum levels with low- and high-grade meningiomas.
Results
The serum level of endocan in the group with meningiomas was 283.34 (242.09-358.70) pg/ml and in the control group was 250.29 (207.56-329.71) pg/ml respectively (P = 0.172). Afterwards, patients were divided into three different groups (grades I, II, and III) and compared to the control. The level of endocan in the group with grade I of meningioma showed no significant difference compared to control individuals (P = 0.86). When patients with grade II and grade III compared with the control group, endocan serum levels were statistically significant (P = 0.002, P < 0.001 respectively). Moreover, our findings showed that the different grades of meningiomas were statistically significant compared to each other (P < 0.001) regarding endocan serum levels, meaning that the higher the grade, the higher the endocan serum levels.
Conclusion
Our findings revealed that higher grades of meningioma had higher endocan serum levels, however, the role of endocan in pathogenesis or progression of this type of tumor requiring further exclusively assessment.

Abstract
BACKGROUND Interleukin-37 (IL-37) is a recently described cytokine that emerges as a natural inhibitor of inflammatory and immune responses. However, IL-37 has not yet been investigated in bladder cancer, and its biological role is unknown. OBJECTIVE The purpose of this study was to investigate IL-37 serum levels in patients with bladder cancer and determine whether they were linked to the patients' pathological characteristics. METHODS IL-37 serum levels were measured using a commercial ELISA kit in 60 patients with transitional cell carcinoma (TCC) of the bladder (mean age: 64.55±12.93) and 50 healthy controls (mean age: 62.94±12.69). Non-parametric tests were used for statistical comparisons, and the Cohen's d effect size was calculated to evaluate the practical and clinical significance of the results. RESULTS Our findings indicated an increasing trend in IL-37 serum levels in patients with TCC (42.77±3.36 pg/ml) in comparison with controls (40.51±7.32 pg/ml, p=0.09). However, IL-37 serum levels were found to be significantly higher in male patients (44.72±3.81 pg/ml) and patients aged ≥70 (46.92±6.77 pg/ml) in comparison with male controls (29.96±3.30 pg/ml, p=0.026) and controls aged ≥70 (23.62±4.43 pg/ml, p=0.009). In comparison to similar controls, Cohen's d effect size for patients aged ≥70 years was found to be 0.90. CONCLUSION The findings reveal a higher serum level of IL-37 in patients with TCC, which might be clinically associated with immunosuppression and tumor growth. However, this is a preliminary study, and more research on the biological role of IL-37 and its potential therapeutic effects in bladder cancer is required.

Abstract
Background TNF-α and IL-6 are both pleiotropic cytokines playing major roles in cancer-associated cytokine networks. They have previously been investigated for their function in skin malignancies, mostly melanomas, and studies on non-melanoma skin cancer (NMSC) patients are relatively rara. In this study, we aimed to investigate the associations of serum levels of IL-6 and TNF-α with NMSCs and its clinicopathological features. Methods This cases-control study was carried out to assess the serum levels of TNF-α and IL-6 in 70 NMSC patients, in comparison with 30 healthy individuals, by means of flow cytometric bead-based immuneoassay. Results Serum levels of both TNF-α and IL-6 were significantly higher in NMSC patients (6.470 vs. 4.355 pg/ml; p = 0.0468, respectively), compared to healthy individuals (3.205 vs. 0.000 pg/ml; p = 0.0126, respectively). In the subgroup analysis, squamous cell carcinomas patients had higher serum levels of IL-6 compared to healthy individuals (3.445 vs. 0.000 pg/ml; p = 0.0432). No other significant differences were observed in the serum levels of these two cytokines among different clinicopathological subgroups of the patients. Conclusion The increased levels of TNF-α and IL-6 in NMSC patients can be introduced as an epiphenomenon of a complex cancer-induced cytokine cascade.

Abstract
OBJECTIVE To investigate the inhibitory effect of β-D-mannuronic acid (M2000) on anti-cyclic citrullinated peptide antibodies (anti-CCP), rheumatoid factor (RF), antidouble strand DNA (anti-dsDNA) and acute phase reactants in rheumatoid arthritis (RA) patients. METHODS The study included 40 patients with RA who had an inadequate response to conventional therapy (identifier: IRCT2014011213739N2). The patients were permitted to continue the conventional therapy excluding NSAIDs. 21 of them were treated orally by M2000 at a dose of 500 mg twice daily for 12 weeks and the others did not. Serum samples were collected at baseline, 4 weeks and 12 weeks after treatment and were tested for the serum level of anti-CCP and anti-dsDNA antibodies using enzyme linked immunosorbent assay. The serum level of RF and C-reactive proteins (CRP) was determined by the immunoturbidimetric assay, respectively. RESULTS At baseline, all patients in the M2000 treated group and the control group were positive for anti-CCP, RF. moreover, 4 of 21 (19%) in the M2000 treated group and 2 of the 19 (10.5%) patients in the control group were positive for anti-dsDNA antibodies, respectively. The serum levels of anti-CCP, RF and anti-dsDNA were decreased significantly after M2000 therapy (p<0.001, p<0.001 and p<0.001, respectively). The reduction in the level of anti-CCP was positively correlated with disease activity, swollen joint count and CRP. Furthermore, the level of inflammatory markers ESR and CRP decreased significantly after M2000 therapy (p<0.001 and p<0.004, respectively). CONCLUSION M2000 shows inhibitory effect on anti-CCP, RF, anti-dsDNA antibodies and acute phase reactants in RA patients.

Abstract
INTRODUCTION Endostatin is a C-terminal proteolytic fragment of collagen XVIII and, as with angiostatin and thrombospondin, is known as an antiangiogenic agent. The aim of this study was to assess the level of serum endostatin in patients with oral squamous cell carcinoma (SCC), and its association with the clinicopathological characteristics of the tumor. MATERIALS AND METHODS Using an enzyme-linked immunosorbent assay (ELISA) kit, we investigated the circulating levels of endostatin in the blood serum of 45 patients with oral SCC and 45 healthy controls. RESULTS The mean level of serum endostatin in patients was significantly lower (68.8±85 ng/ml) than in healthy controls (175.6±73 ng/ml) (P<0.001). Serum endostatin levels were significantly lower in patients with lymph node metastasis compared with patients without lymph node metastasis (P<0.001). In addition, serum endostatin level was associated with higher histological grade (P<0.001). There were no apparent correlations between serum endostatin concentration and clinicopathological features such as age, gender, and tumor stage (P>0.05). CONCLUSION Findings of the present study suggest the prognostic and anti-metastatic role of endostatin, and this may be used as a tool for monitoring tumor progression.

Abstract
BACKGROUND The anti-aging property of β-D-mannuronic acid (M2000) as a novel non-steroidal anti-inflammatory and immunosuppressive agent was investigated on several determinants relative to the oxidative stress in an animal model. METHODS Sprague-Dawley rats were used for evaluating the safety and efficacy properties of M2000 on some oxidative stress enzymes, including the following: mitochondrial superoxide dismutase (SOD2), catalase (CAT), glutathione peroxidase (GPX1), glutathione S-transferase (GST), myeloperoxidase (MPO), and inducible nitric oxide synthase (iNOS) gene expression by real-time PCR. Malondialdehyde (MDA), carbonyl protein (PCO) (the lipid and protein oxidation marker, respectively), and total antioxidant capacity (TAC) were tested in serum by biochemical analysis. In addition, cortisol as a steroid hormone was surveyed by chemiluminescence immunoassay after 12 weeks of M2000 consumption. The rats were sacrificed 3 months after daily oral administration of M2000. RESULTS Our findings revealed the favorable effects of M2000 on several antioxidant enzyme and gene expression, including SOD2, CAT, GPX1, and GST; however, our results were not statistically significant. Moreover, there was no significant difference in MDA and PCO as lipid and protein oxidation markers, TAC, and cortisol compared with the control group following M2000 consumption. A slight weight increase in the M2000-treated group was also observed. CONCLUSIONS Our data showed the anti-aging property of M2000 as a novel designed non-steroidal anti-inflammatory drug (NSAID) with immunosuppressive property on various oxidative stress determinants.

Abstract
BACKGROUND To explore the effects of β-d-mannuronic acid (M2000) on levels of Th17, regulatory T (Treg) cells and their related cytokines in patients with ankylosing spondylitis (AS). METHODS 30 AS patients and 15 age and sex-matched healthy individuals were enrolled in this study. The frequencies of Th17 and Treg cells and serum levels of related cytokines were measured by flow cytometry analysis and ELISA respectively, before (baseline) and 3 months after M2000 therapy. RESULTS Significantly higher baseline Th17 cells and serum IL-17, TNF-α and IL-6 were observed in AS patients than in normal controls, whereas baseline levels of Treg cells and serum IL-10 were not significantly different between AS patients and healthy controls. After M2000 therapy, frequencies of Th17 and serum levels of IL-17 and IL-6 significantly decreased in AS patients. The frequencies of Treg cells and serum level of IL-10 were not significantly changed, in comparison to before therapy. Moreover, the correlation analysis showed that frequencies of Th17 and levels of IL-17, TNF-α and IL-6 were positively correlated with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI) scores, whereas Treg cells were revealed to be negatively correlated with BASDAI and BASFI scores. CONCLUSIONS It can be concluded that the oral administration of M2000 as a novel NSAID with the immunosuppressive property that down-regulates Th17 and Th17-related cytokines and facilitates the correction of the Th17/Treg imbalance can be effective in the process of AS treatment.

Abstract
The aim of this study was to investigate the effect of β-D-mannuronic acid (M2000) on hematological parameters in patients with active rheumatoid arthritis. This study was conducted on 25 patients with active rheumatoid arthritis (RA) (identifier: IRCT2014011213739N2). M2000 was administered orally for anemic and non-anemic RA patients at a dose of 500 mg twice daily for 12 weeks. The patients were permitted to continue the conventional treatments excluding NSAIDs. Blood samples were collected at baseline, 4 and 12 weeks after drug administration and were tested for hematological parameters. Moreover, serum levels of TNF-α and IL-6 were analysed before and after M2000 therapy compared to healthy controls using enzyme linked immunosorbent assay method. We found a significant increase in the count of red blood cells and also hemoglobin (Hb) concentration (0.9 g/dL) in anemic patients after 12 weeks of M2000 therapy (p<0.02 and p<0.01, respectively). Furthermore, our results showed an improvement in Hb level (0.45 g/dL) even in non-anemic patients who were treated by M2000 (p<0.04). The leukocytosis in RA patients, significantly decreased in both anemic and non-anemic patients after 12 weeks of M2000 therapy (p<0.02 and p<0.03, respectively). The percent of neutrophils significantly increased in anemic patients (p<0.01) while in non-anemic patients it significantly decreased after 12 weeks of M2000 therapy (p<0.01). The serum levels of IL-6 and TNF-α significantly decreased after 12 weeks of M2000 therapy (p<0.01 and p<0.04, respectively). M2000 improves hematological parameters in RA patients by its potent inhibitory effect on serum levels of TNF-α and IL-6.

Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease characterized by the inflammation of sacroiliac joints and axial skeleton. A combination of genetic, environmental and immunological factors are involved in AS's pathogenesis. TLRs are type I transmembrane glycoproteins that play a crucial role in the innate immune responses against invading pathogens. Observational studies have demonstrated a possible association between TLR dysregulation and AS. The β-d-mannuronic acid (M2000), as a novel NSAID with immunosuppressive property, has shown an inhibitory effect on Toll-like receptor (TLR) 2, 4 signaling in HEK293 cells. In the present study, we investigated the gene expression of Myd88, IKB-alpha, NF-kB and MAPK14 (genes of the TLR/NF-kB Signaling Pathway) in AS patients in comparison to healthy subjects and also the effect of β-d-mannuronic acid on disease activity and mRNA expression of these molecules in affected patients. We showed for the first time that the gene expression level of Myd88, IKB-alpha, NF-kB and MAPK14 was higher in AS patients in comparison to healthy subjects. Moreover we confirmed that the β-d-mannuronic acid not just reduced significantly the disease activity of AS individuals compared to placebo, but also it could significantly decrease the expression level of genes associated with TLR/NF-kB Signaling Pathway in treated patients with M2000. These results may provide a new therapeutic approach to attenuate inflammatory responses in AS patients, (Identified; IRCT 2013062213739N1).

Abstract
CONTEXT β-d-Mannuronic acid (M2000) has shown its therapeutic effects with the greatest tolerability and efficacy in various experimental models such as experimental autoimmune encephalomyelitis (EAE), adjuvant induced arthritis (AIA), nephrotic syndrome, and acute glomerulonephritis. Despite pharmacological effects of β-D-mannuronic acid, there have been no systematic toxicological studies on its safety so far. OBJECTIVE The study was designed to determine the acute and subchronic toxicity of β-D-mannuronic acid, an anti-inflammatory agent, in healthy male NMRI mice and Wistar rats, respectively. MATERIALS AND METHODS For the acute toxicity study, the animals received orally five different single doses of β-D-mannuronic acid and were kept under observation for 14 d. In the subchronic study, 24 Wistar male rats were divided into four groups and were treated orally (gavage) once daily with test substance preparation at dose levels of 0, 50, 250, and 1250 mg/kg body weight for at least 63 consecutive days (9 weeks). Mortality, clinical signs, body weight changes, hematological and biochemical parameters, gross findings, organ weights, and histopathological determinations were monitored during the study. RESULTS The results of acute toxicity indicated that the LD50 of β-D-mannuronic acid is 4.6 g/kg. We found no mortality and no abnormality in clinical signs, body weight, relative organ weights, or necropsy in any of the animals in the subchronic study. Additionally, the results showed no significant difference in hematological, biochemical, and histopathological parameters in rats. CONCLUSIONS Our results suggest that β-D-mannuronic acid is relatively safe when administered orally in animals.

Abstract
The aim of this review was to clarify the role of prostaglandins and prostaglandin receptors in the immunopathology of Alzheimer's disease. A PubMed search was done using the key word, 'Alzheimer's disease' in combination with the term 'prostaglandins'. Articles from the past 10 years were preferentially selected but important ones from the past 20 years were also included according to the authors' judgment. Alzheimer's disease is characterized by pathological hallmarks such as extracellular deposition of the amyloid β-peptide, the appearance of intracellular neurofibrillary tangles, extensive neuronal loss and synaptic changes in the cerebral cortex and hippocampus. These processes induce inflammatory pathways by activating microglia, astrocytes and infiltrating leukocytes that produce inflammatory mediators including cytokines and prostaglandins.Prostaglandins are small lipid mediators derived from arachidonic acid by multi-enzymatic pathways in which cyclooxygenases and phospholipases are the rate-limiting enzymes. In the central nervous system, prostaglandins exhibit either neurotoxic or neuroprotective effects by acting on specific G-protein-coupled receptors that have different subfamilies and differences in their selective agonists, tissue distribution and signal transduction cascades. Further studies on the role of prostaglandins in Alzheimer's disease may contribute to clarification of their neuroprotective actions, which may lead to the development of successful therapeutic strategies.

Abstract
Osteopontin (OPN) is a multifunctional glycophosphoprotein that was detected in many carcinomas, and it may have a prognostic role. The aim of this study was to determine osteopontin serum levels in patients with oral squamous cell carcinoma (OSCC) and investigated its correlation with clinicopathological features of tumor. Using an ELISA kit, we assessed and compared the circulating levels of OPN in blood serum of 45 oral squamous cell carcinoma patients with 45 healthy control samples. The serum osteopontin level in patients with OSCC was significantly higher (145.8 ± 14.6 ng/ml, n = 45) compared with the healthy controls (53.9 ± 9.6 ng/ml, n = 45, p < 0.001). Mean serum osteopontin level was significantly higher in patients with nodal metastasis (p = 0.03) and higher stage (p = 0.02). Findings of the present study suggest that OPN may have a potential role in pathogenesis of OSCC and it may be used as a tool for monitoring tumor progression.

Abstract
BACKGROUND Oral lichen planus is a chronic inflammatory disease with a poorly understood etiology. The role of angiogenesis in the development of different chronic inflammatory diseases is of great concern. Vascular endothelial growth factor (VEGF) is an important regulator of angiogenesis. We aimed to evaluate the serum level of VEGF in patients with oral lichen planus compared with normal individuals and consider its clinical significance. METHODS In this case-control study, 36 serum samples from patients diagnosed with oral lichen planus admitted to the Oral Medicine Department of the School of Dentistry at Shiraz University of Medical Sciences (14 men, 22 women, mean [±SD] age: 38.8 [±6.07] years) and 23 serum samples from healthy individuals (9 men, 14 women, mean [±SD] age: 38.7 [±4.9] years) were collected. VEGF concentration was measured using the ELISA method. The Mann-Whitney test was used for statistical analysis. RESULTS The serum VEGF level was significantly higher in patients with oral lichen planus compared with the healthy controls (112.97 [±63.2] vs. 66.21 [±56.2] ngr/ml, P<0.001). A similar difference was also observed between the two types of oral lichen planus, being more pronounced in the erosive form (P<0.001). CONCLUSION Serum VEGF can be used as a useful and suitable marker to scrutinize the disease activity.

Abstract
INTRODUCTION HER2/neu, a member of the epidermal growth factor receptor family, has been shown to be over-expressed in some tumors. The purpose of this study was to determine the salivary levels and tissue expression of HER2/neu in patients with head and neck squamous cell carcinoma (HNSCC) and their correlation with clinicopathologic parameters. MATERIALS AND METHODS Enzyme-linked immunosorbent assays (ELISA) were used to evaluate the salivary levels of HER2/neu and immunohistochemistry was used to measure tissue expression of HER2/neu in 28 patients with HNSCC and 25 healthy control subjects. RESULTS The salivary levels of HER2/neu in patients with HNSCC were not significantly higher compared to healthy control subjects. There was no apparent correlation between salivary HER2/neu levels and clinicopathological features such as age, sex, tumor grade, tumor size and nodal status. All HNSCC specimens were positive (membranous or/and cytoplasmic) for HER2/neu, except one sample. Only one HNSCC specimen showed staining purely in the tumor-cell cytoplasm. All control specimens were also positive for both membranous and cytoplasmic HER2/neu but there was a significant difference between the level of cytoplasmic staining in the HNSCC specimens and in the control specimens (P<0.05). CONCLUSION In our study, no overexpression of HER2/neu was observed. Thus, identification of HER2/neu levels plays no role in differentiating between normal and squamous cell carcinoma tissues or detecting the carcinogenesis process. Our findings suggest that the use of HER2/neu as a salivary marker of HNSCC is not recommended, because no significant preoperative elevation and no association with clinicopathological features were found.

Abstract
BACKGROUND Oral Lichen planus (OLP) is a chronic lesion of the oral mucosa with unknown origin. Basement membrane changes are common in OLP and may be mediated by proteases such as matrix metalloproteinase (MMPs) and mast cell chymase. The aim of our study was to evaluate the level of serum MMP-3 in OLP com-pared to normal individuals and assess its clinical significance. METHODS Thirty four serum samples from patients diagnosed with OLP (12 males, 22 females, age: 42.2±10.8 years) and 34 serum samples from healthy control subjects (11 males, 23 females, age: 42.5±13.3 years) were collected and MMP-3 concentration was measured by ELISA. RESULTS The serum MMP-3 level in OLP patients was higher (21.64±24.31 ng/ml) compared with healthy con-trols (16.52±23.63 ng/ml), but showed no statistically significant difference. A statistically significant difference was demonstrated between the two types of OLP, being more pronounced in the erosive/atrophic form 6). CONCLUSION The different clinical appearances of OLP are associated with significant differences in MMP-3 serum level.

Abstract
BACKGROUND The alteration of Th1 and Th2 cytokine levels is the subject of controversy in pleural effusions caused by malignancy, a situation that favors a Th2 immune response. OBJECTIVE To examine the different levels of IL-4 and IL-10 (Th2 cytokines), and IL-2 and interferon-γ (IFN-γ) (Th1 cytokines) in malignant and non-malignant pleural effusions. METHOD The cytokine levels in pleural fluid of 62 patients with malignant pleural effusion (44 with lung cancer and 18 with extrathoracic tumors), 8 with tuberculous and 8 with congestive heart failure pleural effusion were analyzed using enzyme-linked immunosorbent assays. RESULTS IL-2 was below the detectable concentration of the assay. A significant decrease in IFN-γ level was observed in malignant but not in congestive heart failure cases compared to tuberculous cases. IL-10 levels were higher in malignant and tuberculous pleural effusions than in congestive heart failure pleural effusions, however, this difference did not reach the significant level. IL-4 levels were also increased non-significantly in lung cancer pleural effusions compared to the other groups. CONCLUSION Our results show a wide variation in IL-4, IL-10, and IFN-γ levels in malignant pleural effusions, a pattern which was not convincing enough to differentiate the cause of effusion.

Abstract
p53 tumoral suppressor gene harbors a functional polymorphism which codes either arginine (Arg) or proline (Pro) in the protein p53 of codon 72. Such polymorphism has been associated with the development or prognosis of head and neck squamous cell carcinoma (HNSCC). Aim: we assessed codon 72 p53 allelic frequencies and genotypes in HNSCC Iranian patients. Study design: Case Study. Materials and Methods: a total of 132 HNSCC patients and 123 healthy controls were genotyped. DNA source was from mononuclear cells of the peripheral blood. DNA amplification was done by means of the allele-specific polymerase chain reaction. Results: genotypes and allele distribution were not significantly different between patients and controls. Moreover, no statistically significant association was found between the 72 and p53 codon tumor location, gender or age at the time of diagnosis. However, the Pro/Pro genotype was significantly increase in stage IV patients (30.8%) when compared to stages I-III of the disease (11.1%) (p=0.03), and a significantly higher percentage of patients with the Pro allele had and a risk increase in stage IV disease (OR=2.2, 95% CI=1.2-4.2, p=0.01). Conclusion: data revealed that the p53 polymorphism do not impact the risk of HNSCC in Iranians, nonetheless, it can affect tumor progression to a higher tumor stage.

Abstract
Inflammation has been linked to various steps in tumorigenesis. Interleukin (IL)-6 and IL-18 are two inflammatory cytokines whose serum concentrations are elevated in several types of cancer, including head and neck squamous cell carcinoma (HNSCC) in some studies. This study was designed to analyze the serum concentrations of these cytokines in Iranian HNSCC patients. Serum IL-6 and IL-18 concentrations were assayed by ELISA commercial kits in 65 untreated patients and 20 healthy volunteers. Serum IL-6 concentration was significantly increased in patients compared to healthy individuals (p < 0.000). IL-6 concentration increased as the tumor stage progressed, and a significant difference appeared between stage IV vs. stage I/II/III (p = 0.03) disease. Although serum IL-18 concentration was higher in patients than in healthy individuals, the difference was not statistically significant (p = 0.06). Moreover, there was no association between serum IL-18 concentration and tumor stage (p = 0.47). A significant difference was observed in serum IL-18 concentration according to the gender with higher IL-18 concentration in male patients (p = 0.01). In conclusion, serum concentration of IL-6 might correlate with the stage of tumor progression in Iranian HNSCC patients. Further studies with larger numbers of patients are required to exclude the possible minor correlation of serum IL-18 concentration with tumor stage.

Abstract
BACKGROUND The association of a functional single nucleotide polymorphism at codon 72 of the p53 gene (Arg72Pro) with malignancy is a subject of controversy. We analyzed this polymorphism in 224 patients with gastrointestinal cancers (92 with stomach cancer and 132 with colorectal cancer) and in 163 healthy controls. MATERIAL AND METHODS DNA was extracted from peripheral blood mononuclear cells and amplified with an allele-specific polymerase chain reaction. RESULTS There was no significant association between p53 alleles and gastrointestinal cancers. The frequency of the Arg allele was 59.7, 58.8, and 59.2% in the stomach cancer patients, colorectal cancer patients, and controls, respectively. Frequencies of the Pro allele were 40.3% in patients with stomach cancer, 41.2% in patients with colorectal cancer, and 40.8% in controls. Likewise, genotype frequencies did not differ significantly between the two patient groups and controls. There were no differences in genotype or allele frequencies by gender, age, or histological grade. CONCLUSIONS The data do not support the association of the p53 codon 72 polymorphism with stomach or colorectal cancers in Iranian patients.

Abstract
The germline mutations of breast cancer susceptibility genes 1 (BRCA1) and breast cancer susceptibility genes 1 (BRCA2) have been associated with a significant increase in breast cancer risk and certain other cancers. Among the most known mutations in these tumor suppressor genes are 5382insC and 185delAG in BRCA1 and 6174delT in BRCA2. The aim of the current study was to investigate the frequency of these BRCA1 and BRCA2 mutations in southern Iranian familial and sporadic cases with breast cancer.Two hundred fifty women with sporadic breast cancer, 55 women with a familial history of breast cancer in their first degree-relatives and 200 healthy women formed the studied groups. DNA from peripheral blood mononuclear cells was extracted and analyzed by a multiplex polymerase chain reaction method. The data of this investigation indicated that the aforementioned founder mutations were not detected in the groups studied. Our results indicate that 5382insC and 185delAG mutations in BRCA1 and 6174delT in BRCA2 have much less frequency in Iranian breast cancer patients.

Abstract
OBJECTIVE Gestational trophoblastic neoplasms (also termed gestational trophoblastic diseases [GTDs]) encompass a spectrum of interrelated tumors originating from trophoblasts. The search is ongoing for identification of the culpable gene defects in GTDs. Considering the role of PDCD1, CTLA-4 and p53 genes in immune regulation and tumor progression, we explored the association of single-nucleotide polymorphisms (SNPs) corresponding to each gene and GTDs. STUDY DESIGN In a genetic association study, PD1.5 (7785) C/T, CTLA-4 +49 A/G, and p53 codon 72 Arg/Pro SNPs were genotyped in case-control groups with patient/control ratios of 92:295, 83:84 and 85:150, respectively. RESULTS The C/T genotype of the PDCD1 gene was significantly more prevalent among patients with GTDs (40.2%) than controls (19%) (odds ratio [OR] = 2.87; 95% CI = 1.72, 4.77; p < 0.001). Moreover, the C allele was present in 65.8% of patients and 49.5% of controls (OR = 1.96; 95% CI = 1.38, 2.76; p < 0.001). There was no difference in the distribution of each genotype or allele between patients with GTDs and controls considering other studied SNPs. CONCLUSION The results of the current study demonstrate that SNPs in the PDCD1 gene confer susceptibility to GTDs, while there is no association between CTLA-4 and p53 gene polymorphisms and GTDs in an Iranian population.

Abstract
OBJECTIVE Gestational trophoblastic diseases (GTDs) consist of a spectrum of disorders characterized by an abnormal proliferation of trophoblastic tissue. IL-18 is a pleiotropic cytokine with a capacity for both ThI and Th2 polarization. Considering the association of IL-18 promoter polymorphisms at positions -607 (A/C) and -137 (C/G) with pregnancy events and some cancers, we sought to examine these polymorphisms in Iranian patients with GTD, their association with disease subtypes, and IL-18 serum level. STUDY DESIGN Single nucleotide polymorphisms (SNPs) were analyzed by allele-specific polymerase chain reaction in 92 patients with GTDs and 103 healthy pregnant controls. IL-18 serum level was determined using ELISA method. RESULTS No significant association was found between the allele, genotype, genotype combination and haplotype distribution of these SNPs and GTDs or its subgroups. Mean IL-18 serum level was significantly higher in patients with choriocarcinoma and pregnant controls compared with nonpregnant controls (p = 0.04, 0.04 and 0.001, respectively). -137 GG genotype pregnant controls had a significantly higher IL-18 serum level compared with CC genotype. CONCLUSION IL-18 promoter polymorphisms do not confer susceptibility to GTDs or its variants; however, their functional significance is demonstrated in this study. Furthermore, IL-18 serum level increases in GTDs and in normal pregnancy.

Abstract
HER2/neu and TGF-beta1 are over-expressed in various types of malignancies. It appears that they play an important role in the biologic behavior of tumors and have prognostic value. Gestational tropoblastic diseases (GTDs) comprise of a heterogeneous group characterized by abnormally proliferating trophoblastic tissues, ranging from benign to malignant. The objective of this study was to measure and compare the serum levels of s-HER2 and TGF-beta between patients with GTDs and pregnant and non-pregnant controls. Serum levels of s-HER2 and TGF-beta1 were determined by ELISA method in 95 GTD patients (55 complete moles, 32 persistent moles, and 8 choriocarcinoma), 30 normal pregnant controls, and 22 normal non-pregnant controls. Mean serum level of s-HER2 did not differ significantly between patients and controls. TGF-beta1 serum level was significantly higher in GTD patients (20.29 +/- 10.68 pg/ml with 95% confidence interval (CI) of 18.10-22.48 pg/ml) compared with pregnant controls (10.26 +/- 11.84 pg/ml with 95% CI of 5.75-14.76 pg/ml) and non-pregnant controls (7.27 +/- 9.61 pg/ml with 95% CI of 3.01-11.53 pg/ml) (P < 0.001). Our findings suggest that TGF-beta1 serum levels in GTD patients may represent a potential prognostic marker. Further investigations with larger sample size and more frequent sampling are required to elucidate this issue.

Abstract
BACKGROUND AND AIM Cytotoxic T-lymphocyte antigen-4 (CTLA-4) is a potent immunoregulatory molecule that suppresses antitumor response by down-regulating T-cell activation. Effects of several polymorphisms in CTLA-4 on CTLA-4 expression and function have been previously documented. The aim of this study was to investigate the putative effect of CTLA-4 polymorphisms on susceptibility to gastric and colorectal cancers in an Iranian population. METHODS A total of 155 patients (109 with colorectal cancer and 46 with gastric cancer) and 190 age- and sex-matched healthy controls were evaluated. Genotyping of -1722T/C, -1661A/G, and +49A/G were performed by PCR restriction fragment length polymorphism methods and of -318C/T by a PCR amplification refractory mutation system technique. RESULTS No statistically significant differences were found in the genotype distribution and allele frequencies among patients and controls. Haplotype analysis demonstrated that the TACG haplotype (-1722T, -1661A, -318C, +49G) frequency was significant increased in patients with colorectal cancer (P = 0.009) and gastric cancer (P = 0.006) in comparison to the control group. In contrast, the TACA haplotype frequency was significantly decreased in patients with colorectal cancer (P = 0.02) and not significantly decreased in patients with gastric cancer (P = 0.13) compared to the control group. CONCLUSION A positive association between CTLA-4 TACG haplotype and gastric and colorectal cancers was found in an Iranian population. A protective role for TACA haplotype is postulated.

Abstract
Breast cancer is the most common female malignancy worldwide. Despite the high incidence of sporadic cases, the rate of familial breast cancer is low. The tumor suppressor gene TP53 (alias p53), located on chromosome 17, has been involved in various malignancies. Mutations in codon 72 of TP53 have been studied in breast cancer and most solid tumors. For study of polymorphisms and allele frequency, 221 female patients with sporadic breast cancer and 205 healthy blood donors as control group were recruited. DNA from peripheral blood mononuclear cells was extracted and amplified using allele-specific polymerase chain reaction. Frequency of homozygotic arginine at codon 72 was 37.6% in patients and 36.6% in controls, for homozygotic proline it was 13.1 and 19.5%, and for heterozygotic Arg/Pro it was 49.3 and 43.9%, respectively. No significant difference was found between patients and controls regarding allele frequencies. Mutation in codon 72 of TP53 gene was not associated with breast cancer in Iranian patients.
