Abstract
PURPOSE Colon cancer is a prevalent cancer globally, representing approximately 10% of all cancer cases and accounting for 10% of all cancer-related deaths. Therefore, finding new therapeutic methods with high efficiency will be very valuable. Cromolyn (C), a common anti-allergic and mast cell membrane stabilizing drug, has recently shown valuable anti-cancer effects in several studies. This study was designed to investigate the anti-cancer activity of cromolyn on colon cancer in vitro and in vivo and to determine values such as selectivity index and survival effect. METHODS HT-29 (colon cancer) and MCF-10 (normal epithelial) cell lines were treated with C and Doxorubicin (DOX; Positive control). IC50 values and the effects of C and DOX on apoptosis were explored using methyl thiazole diphenyl-tetrazolium bromide (MTT) assay and Annexin V/PI Apoptosis Assay Kit. To investigate in an animal study, colon cancer was subcutaneously induced by CT26 cells (mouse colon cancer) in bulb/c mice. Mice were treated with 0.05 LD50 intraperitoneal every other day for 35 days. After the death of mice, tumor volume, tumor weight, and survival rate were evaluated. RESULTS C selectively and significantly suppressed the proliferation of cancer cells in a dose-dependent manner. The IC50 values for the MCF-10 and HT29 cell lines were 7.33 ± 0.78 μM and 2.33 ± 0.6 μM, respectively. Notably, the selective index (SI) highlighted that C displayed greater selectivity in inhibiting cancer cell growth compared to DOX, with SI values of 3.15 and 2.60, respectively. C exhibited higher effectiveness and selectivity in inducing apoptosis in cancer cells compared to DOX, with a significant p-value (61% vs. 52%, P-value ≤ 0.0001). Also, in mice bearing colon cancer, C reduced the tumor volume (6317 ± 1685mm3) and tumor weight (9.8 ± 1.6 g) compared to the negative control group (weight 12.45 ± 0.9 g; volume 7346 ± 1077) but these values were not statistically significant (P ≤ 0.05). CONCLUSION Our study showed that cromolyn is a selective and strong drug in inhibiting the proliferation of colon cancer cells. Based on our results, the efficacy of C in vitro analysis (MTT assays and apoptosis), as well as animal studies is competitive with the FDA-approved drug doxorubicin. C is very promising as a low-complication and good-efficacy drug for cancer drug repositioning. This requires clinical research study designs to comprehensively evaluate its anti-cancer effects.

Abstract
BACKGROUND Natural killer (NK) cells, CD3- lymphocytes, are critical players in cancer immune surveillance. This study aimed to assess two types of CD3- NK cell classifications (subsets), that is, convectional subsets (based on CD56 and CD16 expression) and new subsets (based on CD56, CD27, and CD11b expression), and their functional molecules in the peripheral blood of patients with breast cancer (BC) in comparison with healthy donors (HDs). METHODS Thirty untreated females with BC and 20 age-matched healthy women were enrolled. Peripheral blood samples were collected and directly incubated with fluorochrome-conjugated antibodies against CD3, CD56, CD16, CD27, CD11b, CD96, NKG2C, NKG2D, NKp44, CXCR3, perforin, and granzyme B. Red blood cells were then lysed using lysing solution, and the stained cells were acquired on four-color flow cytometer. RESULT Our results indicated 15% of lymphocytes in peripheral blood of patients with BC and HDs had NK cells phenotype. However, the frequency of total NK cells (CD3-CD56+), and NK subsets (based on conventional and new classifications) was not significantly different between patients and HDs. We observed mean fluorescent intensity (MFI) of CXCR3 in total NK cells (p = .02) and the conventional cytotoxic (CD3-CD56dim CD16+) NK cells (p = .03) were significantly elevated in the patients with BC compared to HDs. Despite this, the MFI of granzyme B expression in conventional regulatory (CD3-CD56brightCD16- /+) NK cells and CD3-CD56-CD16+ NK cells (p = .03 and p = .004, respectively) in the patients was lower than healthy subjects. CONCLUSION The higher expression of chemokine receptor CXCR3 on total NK cells in patients with BC may be associated with increased chemotaxis-related NK cell infiltration. However, lower expression of granzyme B in conventional regulatory NK cells and CD3-CD56-CD16+ NK cells in the patients compared to HDs suggests reduced cytotoxic activity of the NK cells in BC. These results might demonstrate accumulating NK subsets with a dysfunctional phenotype in the peripheral blood of patients with BC.

Abstract
Colon cancer is one of the most common cancers and one of the main causes of death worldwide. Therefore, new treatment methods with better efficiency and fewer risks are very necessary. Mebendazole (MBZ), a drug commonly used for helminthic infections, has recently received attention as a suitable candidate for the treatment of various cancers. This study aimed to investigate, in vitro and in vivo, anticancer activity and selectivity Index of MBZ on colon cancer. HT-29 (human colorectal adenocarcinoma) and MCF-10 (non-tumorigenic epithelial) cell lines were treated with MBZ and Doxorubicin (DOX; positive control drug). IC50 values were estimated using methyl thiazole diphenyl-tetrazolium bromide (MTT) assay. We employed flow cytometry using annexin V-FITC and propidium iodide dyes. For the animal study, colon cancer was subcutaneously induced by CT26 cells (mouse colon cancer) in Bulb/C mice. The mice were treated with 0.05 of LD50, intraperitoneal, every other day for 35 days. Finally, the survival rate, tumor volume, and tumor weight were calculated. Our results demonstrated that IC50 values after 72 h for HT29 and MCF-10 cell lines were 0.29 ± 0.04 µM and 0.80 ± 0.02 µM, respectively. MBZ was more selective than DOX in inhibiting the proliferation of cancer cells compared to normal cells (2. 75 vs. 2.45). Annexin V/PI staining demonstrated that MBZ treatment at IC50 concentrations induced (78 ± 12%) apoptosis in the HT29 cancer cell line after 48 h (P ≤ 0.0001). Also, in mice bearing colon cancer, MBZ significantly reduced the tumor volume (1177 ± 1109 mm3; P ≤ 0.001) and tumor weight (2.30 ± 1.97 g; P ≤ 0.0001) compared to the negative control group (weight 12.45 ± 2.0 g; volume 7346 ± 1077). Also, MBZ increases mean survival time (MST) and increase life span (ILS) percentage in the animal study (51.2 ± 37% vs 93%, respectively). This study suggests that mebendazole strongly and selectively inhibits proliferation and induces apoptosis in colon cancer cells. It may be, accordingly, a promising drug for clinical research and application.

Abstract
BACKGROUND Seminoma and dysgerminoma are rare testicular and ovarian germ cell tumors characterized by a significant infiltration of immune cells in the tumor microenvironment. According to the failure of conventional treatments in some patients, it is crucial to identify novel prognostic and therapeutic biomarkers for these patients. The objectives of this study were to evaluate the expression of CD45RO and PD-1/PD-L1 and investigate their association with the clinicopathological characteristics of the patients. METHODS Immunohistochemistry was performed to assess the expression of CD45RO, PD-1, and PD-L1 in tumor-infiltrated lymphocytes (TILs), and tumor cells in 33 seminoma and 31 dysgerminoma patients. The expression levels were evaluated using a semiquantitative approach, weighted histoscore, which considers both the intensity and extent of staining. RESULTS All seminoma and dysgerminoma patients exhibited CD45RO expression in TILs, with 66.7 % and 90.3 % displaying high levels of expression, respectively. PD-1 expression in TILs was observed at low levels in 81.8 % and 77.4 % and at high levels in 18.2 % and 19.4 % of seminoma and dysgerminoma patients, respectively. Likewise, low expression of PD-L1 in tumor cells was detected in 63.6 % of seminoma and 61.3 % of dysgerminoma patients, while none of the patients exhibited high expression of PD-L1. In seminoma patients, a positive correlation was observed between PD-1 expression in TILs and CD45RO expression and between PD-L1 expression in tumor cells and TILs score. CONCLUSION The frequent infiltration of CD45RO, along with variable expression of PD-1 and PD-L1 on TILs and tumor cells, could impact the effectiveness of anti-tumor responses and immunotherapy.

Abstract
Background CD38 is highly expressed on multiple myeloma (MM) cells and has been successfully targeted by different target therapy methods. This molecule is a critical prognostic marker in both diffuse large B-cell lymphoma and chronic lymphocytic leukemia. Objective We have designed and generated an anti-CD38 CAR-NK cell applying NK 92 cell line. The approach has potential application as an off-the-shelf strategy for treatment of CD38 positive malignancies. Methods A second generation of anti-CD38 CAR-NK cell was designed and generated, and their efficacy against CD38-positive cell lines was assessed in vitro. The PE-Annexin V and 7-AAD methods were used to determine the percentage of apoptotic target cells. Flow cytometry was used to measure IFN-γ, Perforin, and Granzyme-B production following intracellular staining. Using in silico analyses, the binding capacity and interaction interface were evaluated. Results Using Lentivirus, cells were transduced with anti-CD38 construct and were expanded. The expression of anti-CD38 CAR on the surface of NK 92 cells was approximately 25%. As we expected from in silico analysis, our designed CD38-chimeric antigen receptor was bound appropriately to the CD38 protein. NK 92 cells that transduced with the CD38 chimeric antigen receptor, generated significantly more IFN-γ, perforin, and granzyme than Mock cells, and successfully lysed Daudi and Jurkat malignant cells in a CD38-dependent manner. Conclusion The in vitro findings indicated that the anti-CD38 CAR-NK cells have the potential to be used as an off-the-shelf therapeutic strategy against CD38-positive malignancies. It is recommended that the present engineered NK cells undergo additional preclinical investigations before they can be considered for subsequent clinical trial studies.

Abstract
BACKGROUND To investigate the differential expression of PD-1 and PD-L1 in salivary gland tumors (SGTs, malignant and benign subtypes) and determine their association with the clinicopathological characterization of the patients. METHODS The immunohistochemistry was used to examine PD-1 and PD-L1 expression in specimens from 83 patients with primary SGTs including salivary ductal carcinoma (SDC), adenoid cystic carcinoma (AdCC), acinic cell carcinoma (ACC), mucoepidermoid carcinoma (MEC), warthin's tumors (WT), poleomorphic adenoma (PA) and other subtypes. RESULTS The expression of PD-1 in peripheral and central immune cells (ICs) of MEC, and peripheral ICs of ACC was significantly higher than those with AdCC (P = 0.02, P = 0.02, P = 0.03, respectively). Interestingly, the expression of PD-1 was also observed in peripheral and central malignant tumor cells (TCs), particularly in SDC and ACC. Despite no significant difference in PD-L1 expression of TCs among malignant subtypes, the peripheral and central ICs of ACC and MEC were revealed to express PDL-1 significantly more than those with AdCC (P < 0.05). WTs were rich in PD-1/PD-L1 expressing ICs. However, the tumor microenvironment of PA generally had low levels of PD-1/PD-L1 expression. In general, the expression of PD-1 in peripheral and central TCs was found to be significantly higher in malignant tumors than in benign ones (P = 0.002 and P = 0.003, respectively). CONCLUSION The simultaneous presentation of PD-1 and PD-L1 in TCs and ICs of SGTs, their significant association with disease severity as well as the positive correlation between these immune checkpoints may suggest the therapeutic potential of anti-PD-1 and anti-PDL-1 combinational immunotherapy for SGTs.

Abstract
Background: Ursane triterpenoids could be considered as novel multi-target therapeutic anti-cancer agents. Salvurmin A and Salvurmin B are novel cytotoxic ursane triterpenoids isolated from the aerial parts of Salvia urmiensis, an endemic plant species of Iran. The isolation and structure elucidation were reported in our recent publication. Methods: In this study, we assessed cytotoxicity of these compounds against two human cancer cell lines and one human normal cell line and investigated its mechanism via apoptosis and cell cycle arrest. Results: Salvurmin A and B showed the most cytotoxic effect on A549 cells compared to other studied cancer cells. IC50 values for Salvurmin A and B against A549 cells were 35.6 ± 1.5 and 19.2 ± 0.8 µM, respectively. Based on annexin V staining, both of these compounds significantly induced apoptosis in A549 cells. Moreover, these two compounds significantly increased cell accumulation in G2/M and decreased the number of cells in G0/G1 phases in A549 cells in a dose-dependent manner. Conclusions: Based on the results Salvurmin B can be considered as potential candidate for further studies against human lung carcinoma.

Abstract
Objective Salivary gland tumors (SGTs) show some aggressive and peculiar clinicopathological behaviors that might be related to the components of the tumor microenvironment, especially mesenchymal stem cells (MSCs)-associated proteins. However, the role of MSCs-related proteins in SGTs tumorigenesis is poorly understood. This study aimed to isolate and characterize MSCs from malignant and benign tumor tissues and to identify differentially expressed proteins between these two types of MSCs. Materials and Methods In this experimental study, MSC-like cells derived from benign (pleomorphic adenoma, n=5) and malignant (mucoepidermoid carcinoma, n=5) tumor tissues were verified by fluorochrome antibodies and flow cytometric analysis. Differentially expressed proteins were identified using two-dimensional polyacrylamide gel electrophoresis (2DE) and Mass spectrometry. Results Results showed that isolated cells strongly expressed characteristic MSCs markers such as CD44, CD73, CD90, CD105, and CD166, but they did not express or weakly expressed CD14, CD34, CD45 markers. Furthermore, the expression of CD24 and CD133 was absent or near absent in both isolated cells. Results also discovered overexpression of Annexin A4 (Anxa4), elongation factor 1-delta (EF1-D), FK506 binding protein 9 (FKBP9), cytosolic platelet-activating factor acetylhydrolase type IB subunit beta (PAFAH1B), type II transglutaminase (TG2), and s-formylglutathione hydrolase (FGH) in MSCs isolated from the malignant tissues. Additionally, heat shock protein 70 (Hsp70), as well as keratin, type II cytoskeletal 7 (CK-7), were found to be overexpressed in MSCs derived from the benign ones. Conclusion Malignant and benign SGTs probably exhibit a distinct pattern of tissue proteins that are most likely related to the metabolic pathway. However, further studies in a large number of patients are required to determine the applicability of identified proteins as new targets for cancer therapy.

Abstract
BACKGROUND A recently introduced CD4+ T subset that mainly secretes interleukin (IL-) 22 has been reported to be associated with a variety of tumors, including colon, gastric, hepatocellular, and small- and large-cell lung carcinoma. Both tumor-promoting and - suppressing roles have been suggested for these cells. In the present study, we aimed to investigate the frequency of IL-22-producing subsets in tumor-draining lymph nodes (TDLNs) of the patients with breast cancer and determine their association with the clinicopathological characterizations of the disease. METHODS Thirty untreated women diagnosed with breast cancer were enrolled and their axillary lymph nodes were dissected during surgery. Mononuclear cells were isolated using Ficoll density gradient, activated, permeabilized, and stained by fluorochrome-conjugated antibodies against CD4, IL-22, IL-17, and IFNγ. The cells were then acquired on the FACSCalibur flow cytometer, and raw data was analyzed by the FlowJo software package (V10). RESULTS Our results demonstrated that 2.39% ± 0.39 of CD4+ lymphocytes in TDLNs of patients with breast cancer produced IL-22. Among them, 0.64% ± 0.8 just produced IL-22 but were negative for IFNγ and IL-17. Statistical analysis indicated that the frequency of CD4+IL-22+ cells was significantly higher in the patients with stage III and the ones with 3-9 tumor involved lymph nodes (N2) compared to those with stage II and those having 1-3 tumor involved lymph nodes (N1) (P = 0.008 and P = 0.004, respectively). CONCLUSION The higher frequency of IL-22-producing cells in draining lymph nodes of patients with more advanced tumors (higher stage (stage III) and more involved lymph nodes) suggests a role for IL-22-producing cells in the tumor progression and invasion. However, further studies with larger sample size and more functional studies are needed to clarify the role of IL-22-producing cells in breast cancer pathogenesis.

Abstract
BACKGROUND Streptococcus pneumoniae is the leading cause of pneumonia, mostly in children less than five years and elderly people. Although the Pneumoniae Polysaccharide Vaccine (PPV) and Pneumonia Conjugate Vaccines (PCV) are the efficient pneumococcal vaccine in adults and children, the serotype replacement of S. pneumoniae strains causes the reduction in the efficacy of PPV and PCV vaccines. Epitope-based vaccines are a promising alternative to the present capsular antigen vaccines. METHODS In this study, we evaluated cellular and humoral immune responses induced by our novel designed multi-epitope vaccine in BALB/c mice. CD8+ Cytolytic T Lymphocytes (CTLs) epitopes were selected from PspA and CbpA antigens, and CD4+ Helper T Lymphocytes (HTLs) epitopes were chosen from PhtD and PiuA antigens. PorB, the TLR2 agonist, as an adjuvant, was employed to increase the immunogenicity of the vaccine. RESULTS AND CONCLUSION The high levels of specific anti-peptide vaccine IgG and an increase in the level of IgG2 in the vaccinated group demonstrated our vaccine could elicit robust antibody production. The significant increase in IFN-γ, IL-2, TNF-α, IL-4, IL-6, and decrease in IL-10 showed that the designed vaccine could be proposed as the efficient preventative pneumococcal vaccine in the mouse model.

Abstract
Bioassay-guided fractionation of a dichloromethane extract of the aerial parts of Salvia urmiensis, an endemic plant species of Iran, led to the isolation of two new cytotoxic ursane triterpenoids, Salvurmin A and Salvurmin B. Their structures were elucidated by a combination of 1D and 2D NMR, HR-ESI-MS, IR and UV analysis. Cytotoxicity of the above-mentioned compounds were evaluated against two human cancerous cell lines (SW1116, MCF-7). IC50 values for Salvurmin A and Salvurmin B on colon cancer cell line (SW1116) were 41.6 ± 2.6 and 23.2 ± 0.4 μM respectively, in comparison to cisplatin as control positive. In addition, these two compounds exhibited cytotoxic activity on breast cancer cell line (MCF-7) with an IC50 of 54.2 ± 5.3 and 40.2 ± 3.1 μM for Salvurmin A and Salvurmin B, respectively. The cytotoxic activities of these two compounds present a promising potential for the future investigation on this endemic species of Salvia.

Abstract
Indoleamine 2, 3-dioxygenase (IDO) catabolizes tryptophan, mediates immunomodulatory functions, and is released by stromal cells such as mesenchymal stem cells. The aims of this study were to investigate the effects of IDO silencing on immunosuppressive function of adipose-derived mesenchymal stem cells (ASCs), T cells phenotype, and the proliferation/migration of tumor cells. ASCs isolated from adipose tissues of healthy women were transfected with IDO-siRNA. Galectin-3, transforming growth factor-β1, hepatocyte growth factor, and interleukin-10 as immunomodulators were measured in ASCs using qRT-PCR. T cells phenotype, interferon-γ, and interleukin-17 expression were evaluated in peripheral blood lymphocytes (PBLs) cocultured with IDO silenced-ASCs by flow cytometry and qRT-PCR, respectively. Scratch assay was applied to assess the proliferation/migration of MDA-MB-231 cell line. Galectin-3 was upregulated (p ˂ 0.05) while hepatocyte growth factor was downregulated (p ˂ 0.05) in IDO-silenced ASCs compared to control groups. Regulatory T cells were inhibited in PBLs cocultured with IDO-silenced ASCs; also T helper2 was decreased in PBLs cocultured with IDO-silenced ASCs relative to the scramble group. IDO-silenced ASCs caused interferon-γ overexpression but interleukin-17 downregulation in PBLs. The proliferation/migration of MDA-MB-231 was suppressed after exposing to condition media of IDO-silenced ASCs compared with condition media of untransfected (p < 0.01) and scramble-transfected ASCs (p < 0.05). The results exhibited the weakened capacity of IDO-silenced ASCs for suppressing the immune cells and promoting the tumor cells' proliferation/migration. IDO suppression may be utilized as a strategy for cancer treatment. Simultaneous blocking of immunomodulators along with IDO inhibitors may show more effects on boosting the efficiency of immune-based cancer therapies.

Abstract
INTRODUCTION NK cells have been introduced as the main innate arm of immunity against malignancies. Recent advances introduced new subsets of, and new effector molecules on NK cells suggesting new paradigms for NK cell functions in tumor immunity. Considering these new paradigms, in the current research we investigated the frequency of tumor infiltrating NK cell (TINK) subsets and their functional molecules in breast tumor tissues by flowcytometry method. METHODS Breast tumor tissues were obtained from 32 untreated patients with breast cancer. The tissues were then minced mechanically to acquire a single cell suspension and surface-stained with monoclonal antibodies against CD3, CD56, CD11b, CD27, NKG2A, NKG2D and CXCR3. For intracellular staining (ICS), the surface-stained cells were then fixed, permeabilized and stained with anti-Perforin and anti-Granzyme B antibodies. The samples were run and the data were acquired on a four-color flowcytometer. RESULTS The cell suspension derived from tumor tissue encompassed 3.10 ± 0.52 % CD3-CD56+(bright/dim) total NK cells. Based on the conventional classification the percentages of cytotoxic (CD3- CD56dim) and regulatory (CD3- CD56bright) NK cells were respectively 1.74 ± 0.24 % and 1.36 ± 0.48 %. According to the new classification the percentages of cytotoxic (CD3- CD56+ CD11b+ CD27-), regulatory (CD3-CD56+ CD11b+/- CD27+) and tolerant (CD3-CD56+ CD27- CD11b-) NK cells were respectively 0.48 ± 0.07, 1.55 ± 0.34 and 1.15 ± 0.51. A significant higher frequency of total NK cells (CD3-CD56+ (bright/dim)) in the breast tumor tissues of the patients whose tumor draining lymph nodes (TDLNs) has not been yet involved by tumor cells (LN- patients) compared with the ones with lymph nodes involvement (LN+) (5.91 ± 1.79 % Vs. 2.20 ± 0.20 %, P < 0.004). Furthermore, NK cells with overexpressed activating receptor; NKGD2 (CD3- CD56+(bright/dim) NKG2D+ NK cells) was observed to be elevated in LN- patients compared with the LN+ ones (70.01 ± 7.96 Vs. 42.5 ± 4.81, P < 0.011). Correlation analysis revealed the percentages of conventional regulatory NK cells (CD3- CD56bright) in breast tumor tissue to be in positive correlation with the tumor size (R = 0.380, P < 0.04). The mean percentage of this cell subset was also observed to be higher in patients with T3 tumor size compared with smaller T1 tumor size (1.61 ± 0.20 % vs. 0.75 ± 0.15 %, P < 0.023. CONCLUSION Our observations suggest that accumulation of NK cells as well as the expression of activating NKG2D receptor by TINKs may play roles in breast tumor regression especially in the LN- patients. As the tumor growths and the size of tumor increases the accumulation of regulatory NK cells may facilitate the tumor improvement. These observations may have implications in cancer NK cell-based immunotherapy.

Abstract
Natural killer (NK) cell therapy has proven to be a promising approach for the treatment of malignancies. Osaki method for ex-vivo autologous NK cell expansion has been recently introduced in Japan. To start clinical trial phase I at Shiraz University of Medical Sciences in collaboration with the Japanese group, this preclinical setting study aimed to evaluate the proliferative efficacy of the method, the activation status of expanded autologous NK cells, and the likely unwanted contamination of the final cell product. Peripheral blood mononuclear cells (PBMCs) were isolated from 5 healthy individuals' peripheral blood and transferred directly to the specified initial culture bag containing anti-CD52 and anti-CD3 and Interleukin (IL)-2. The cells were cultured for 14-17 days in an incubator, during which the cells received condition media, and underwent several passages into bigger culture bags. All the procedures were carried out in a cleanroom and associated facilities. Before and after activation PBMCs were analyzed for their phenotype and cytotoxic activity; using flow cytometry and cytokine release assay. Our results indicated that NK (CD3-CD16+/-CD56+) cells were expanded 510-fold on average (range 200-1100 fold), and the purity of NK cells per whole lymphocytes exceeded 68%. The expanded cells were highly lytic as indicated by in-vitro cytotoxic assay, with a strong expression of Natural killer group 2 member D (NKG2D) and CD16. The prepared final cell products were negative for HCV, HBV, HIV, mycoplasma, and endotoxin. In the preclinical phase, large numbers of activated and un-contaminated NK cells from healthy individuals' peripheral blood were successfully generated. The method seems to provide ample clean cell product with no contamination and has the potential to be used for NK cell therapy in future clinical trials, suitable to be infused back to the donors in phase I clinical trial.

Abstract
Introduction and methods To clarify the role of CD4+ regulatory T cells in bladder cancer, we investigated the frequency of these cells in tumor draining lymph nodes of 50 patients with bladder cancer who underwent radical cystectomy using flow cytometry method. We also assessed their association with prognosis and survival. Results On average, 30.13 ± 2.17% of lymphocytes in draining lymph nodes from patients with bladder cancer were positive for both CD4 and FOXP3 molecules. Analyses also showed that 9.92 ± 0.8% of CD4+ lymphocytes had a regulatory phenotype (CD4+CD25+FOXP3+CD127low/neg). The frequency of total CD4+FOXP3+ lymphocytes as well as regulatory T cells was significantly greater in patients with at least one tumor-involved lymph node compared to those with tumor-free nodes (P = 0.026 and P = 0.036, respectively). Mean FOXP3 expression in CD4+ lymphocytes was greater in patients with stage IV compared with those in stage III (P = 0.046). No other significant associations were found between the frequency of regulatory T cells and other clinicopathological characteristics or patient survival. Conclusions The increased frequency of regulatory T cells in patients with involved lymph nodes suggests that these cells may negatively regulate antitumor immune responses in draining lymph nodes. Our findings may have implications for immunotherapy-based treatments for bladder cancer.

Abstract
Alfalfa (Medicago sativa) is a plant with phytoestrogenic properties, which has been used as a major part of diets in husbandry. Since there are controversial reports related to the effects of alfalfa consumption on animal fertility, its effects on rat testicular tissue were assessed in the present study. Control (n=15) and alfalfa (n=15) groups were fed with ordinary rat chow and ordinary rat chow plus alfalfa, respectively. Testicles were removed after 30, 45, and 60 days of consumption, and tissue sections were prepared to assess histomorphometric changes related to alfalfa consumption.
Based on the results, there was no significant difference in length, width, and volume of testes of treated rats to control in all groups. But the number of testicular spermatogonia cells, primary spermatocyte cells, primary spermatid cells, testicular spermatozoid cells and Leydig cells significantly or insignificantly increased in rats that received alfalfa for 30 days but all of these parameters insignificantly decreased in rats that received alfalfa for 60 days. The cause of these changes may be due to estrogenic or anti-estrogenic, antioxidant and endocrine effects of alfalfa.
Conclusion: Consumption of alfalfa for short time had only a transient positive effects on testicular tissues but use of alfalfa for 60 days had little destructive effects on testicular tissue in rats. So longer durations of time could be suggested for further research on the effects of alfalfa on rat’s reproduction index.

Abstract
Sperm cryopreservation leads to various structural and functional damages, some of which induce by oxidative stress. The reactive oxygen species (ROS) generates by mitochondria and membrane NADPH oxidases (NOXs). Among the NOXs, only NOX5 has been identified in the cell membrane of human sperm. This study was designed to clarify the possible role of NOX5 on sperm cryoinjury. Forty human semen samples were washed and randomly divided into fresh and cryopreserved groups. Each group was divided into 4 subgroups containing Ham's F10 (control), 0.1% DMSO (vehicle), 100 nM of PMA (phorbol 12-myristate 13-acetate) and 1 µM of DPI (diphenyleneiodonium), as NOX5 activator and inhibitor. The samples of cryopreserved groups were preserved in liquid nitrogen for 1 month. The sperm kinematics, membrane integrity, ROS production, apoptosis rate, mitochondrial membrane potential (MMP), intracellular ATP and calcium concentration [Ca2+]i were evaluated. The percent of sperm with intact membrane and motile sperm reduced significantly after thawing (p ≤ 0.01). The ROS production (p ≤ 0.01) and the apoptotic rate increased, MMP dissipated, and the percentage of live cells with high [Ca2+]i decreased significantly in the cryopreserved control group relative to the fresh control group. DPI, in contrast to PMA, improved sperm progressive motility (p ≤ 0.01), membrane integrity in fresh and cryopreserved groups and reduced the ROS amount in cryopreserved group (p ≤ 0.01). Apoptotic rate, [Ca2+]i, ATP, and MMP did not change with DPI and PMA in cryopreserved groups. We conclude that NOX5 activity in fresh sperm is low, and it increases during cryopreservation. NOX5 inhibition improves the cryopreserved sperm quality.

Abstract
BACKGROUND L2-based Human Papillomavirus (HPV) prophylactic vaccines, containing epitopes from HPV minor capsid proteins, are under investigation as second-generation HPV vaccines. No such vaccine has passed clinical trials yet, mainly due to the low immunogenicity of peptide vaccines; so efforts are being continued. A candidate vaccine composed of two HPV16 L2 epitopes, flagellin and a Toll-Like Receptor (TLR) 4 agonist (RS09) as adjuvants, and two universal T-helper epitopes was designed in silico in our previous researches. METHODS The designed vaccine construct was expressed in E. coli BL21 (DE3) and purified through metal affinity chromatography. Following mice vaccination, blood samples underwent ELISA and flow cytometry analyses for the detection of IgG and seven Th1 and Th2 cytokines. RESULTS Following immunization, Th1 (IFN-γ, IL-2) and Th2 (IL-4, IL-5, IL-10) type cytokines, as well as IgG, were induced significantly compared with the PBS group. Significant increases in IFN-γ, IL-2, and IL-5 levels were observed in the vaccinated group versus Freund's adjuvant group. CONCLUSION The obtained cytokine induction profile implied both cellular and humoral responses, with a more Th-1 favored trend. However, an analysis of specific antibodies against L2 is required to confirm humoral responses. No significant elevation in inflammatory cytokines, (IL-6 and TNF-α), suggested a lack of unwanted inflammatory side effects despite using a combination of two TLR agonists. The designed construct might be capable of inducing adaptive and innate immunity; nevertheless, comprehensive immune tests were not conducted at this stage and will be a matter of future work.

Abstract
BACKGROUND NK (natural killer) and NKT (natural killer T) cells, as components of innate immune system, play a crucial role in tumor progression and dissemination. OBJECTIVE To investigate the percentages of NK cells, NKT cells, iNKT (invariant natural killer T) cells, total T lymphocytes as well as activated T lymphocytes, in tumor draining lymph nodes (TDLNs) of patients with breast cancer (BC) and their association with different clinic-pathological features of the patients. METHODS Axillary lymph nodes were obtained from 30 Iranian women with breast cancer. After routine pathological evaluations, mononuclear cells were separated from their lymph nodes and incubated with appropriate fluorochrome conjugated monoclonal antibodies specific for CD3, HLA-DR, CD16/56, and Vα24Jα18-TCR. Data were collected on a four-color flow cytometer and analyzed by CellQuest software. RESULTS The mean percentages of NK (CD3-CD16/56+), NKT (CD3+CD16/56+) and iNKT (Vα24Jα18-TCR+) cells in TDLNs mononuclear cells of BC patients were 2.04%, 2.44% and 0.1%, respectively. A significant decrease in the percentages of NK and iNKT subsets in patients with grade I was observed compared to grade III (p=0.03 and p=0.01, respectively). Moreover, NK cells were increased in patients with grade III of BC compared to grade II (p= 0.003). CONCLUSION The increase in the percentage of NK and iNKT cells in TDLNs of patients with higher grade of BC might suggest a suppressive phenotype for these cells in breast cancer, which merit more functional investigation.

Abstract
Plants with anticancer properties are considered as cancer preventive and treatment sources, due to their some biological effects. Apoptosis induction and anti-proliferative effects of Baneh extract on various cancer cell lines have been reported. Hence, this study was designed to evaluate the cytotoxic effects of this fruit on KB and human gingival fibroblast cell lines (HGF). KB and HGF cells were treated with various concentrations of ethanolic Baneh extract and cisplatin as positive control. Cytotoxic activity and apoptosis induction were investigated using WST-1 and Annexin V assays. Data were analyzed using ANOVA and student's t-tests. IC50 after 24 and 48 hours treatment were respectively 2.6 and 1 mg/mL for KB cell line, and 1.5 and 1.6 mg/mL for HGF cell. During 48 hours Baneh extract induced apoptosis without significant necrosis, in a time- and dose-dependent manner. The induction of apoptosis in KB cells was significantly higher than HGF. It seems that ethanolic extract of Baneh contains compounds that can suppress KB cell growth through the induction of apoptosis. Within 48 hours, less cytotoxic effects were observed on normal fibroblast cells; therefore, it might be a potential anticancer agent.

Abstract
Objective: Brain tumors are of high mortality and morbidity for which there is still no cure. The TNF family cytokine, A Proliferation Inducing Ligand (APRIL), is shown to help proliferation and development of tumor cells. We assessed serum levels of APRIL in patients with glioma, meningioma and schwannoma in comparison to healthy individuals. Methods: Peripheral blood samples of 68 patients with brain tumors, divided into three groups of gliomas (n=25), meningiomas (n=30) and schwannomas (n=13), as well as 45 healthy individuals were obtained. Serum samples were prepared and stored in -40°C until usage. Using a commercial ELISA method, APRIL concentration was measured in each serum sample. The obtained data were then analyzed using SPSS software. Results: APRIL serum levels were higher in all patients compared to the controls (P<0.001). Moreover, APRIL serum levels were higher in each of the tumor bearing groups (gliomas, meningiomas and schwannomas) in comparison to the controls (P<0.001, <0.001 and =0.001, respectively). Comparing APRIL between the patients groups showed no significant difference. Age and gender showed no significant correlation with serum APRIL levels, although the age of patients in glioma group was significantly lower than controls (P=0.017). The serum APRIL levels in gliomas with histological grade showed no difference, but in meningiomas, it was lower in tumors with higher grades (P= 0.011). Conclusion: Increased serum levels of APRIL in patients with meningioma and schwannoma as well as glioma may indicate a common role of this cytokine in brain tumors.

Abstract
BACKGROUND Interleukin 17 (IL-17) is a pro-inflammatory cytokine that plays an important role in cancer pathogenesis. OBJECTIVE To investigate the association of two IL-17 gene polymorphisms (rs2275913 and rs763780), as well as IL-17 serum levels with susceptibility to Basal Cell Carcinoma (BCC) of skin. METHODS Two hundred subjects with BCC and 200 healthy controls were recruited. DNA was extracted from peripheral blood leukocytes and genotypes were determined using PCR-RFLP methods. Serum levels were assessed by ELISA. RESULTS At position rs2275913 in IL-17A, the frequencies of GG, AG and AA genotypes were 99 (49.5%), 76 (38%) and 25 (12.5%) in patients and 97 (48.5%), 84 (42%) and 19 (9.5%) in the control group. The distribution of AA, GA and GG genotypes at position rs763780 in IL-17F were 166 (83%), 34 (17%) and 0 (0%) in patients and 158 (79%), 40 (20%) and 2 (1%) in the control group. Haplotype analysis by Arlequin software package revealed that GA haplotype was the most frequent haplotype in both groups. No significant differences were found in alleles, genotypes, and haplotypes frequencies between study groups at both positions (P>0.05). While no difference in IL-17 serum levels was observed between individuals with different genotypes, statistical analysis showed higher IL-17A serum levels, but not IL-17F, in patients compared to controls (0.65 ± 0.11 and 0.03 ± 0.02 pg/ml), respectively, (P<0.001). CONCLUSION Our findings do not support the association of rs763780 and rs2275913 gene polymorphisms in IL-17gene with susceptibility of Iranians with BCC. Increased IL-17A serum levels may still play a role in pathogenesis of BCC.

Abstract
INTRODUCTION Head and neck squamous cell carcinomas (HNSCCs) are the most common cancers of head and neck and the sixth most common malignancy worldwide. Programmed cell death 1 (PD-1) is an immune inhibitory molecule which through interaction with its ligands recruits protein phosphatase resulting in immune response inhibition. Expression of PD-1 ligands on tumor cells is considered as one of the crucial immune evasion mechanisms. This study aimed to investigate the association of PD-1 gene polymorphisms at positions PD1.3 (rs11568821), PD1.5 (rs2227981) and PD1.9 (rs2227982) with susceptibility to HNSCCs. SUBJECTS AND METHODS 150 patients pathologically confirmed to suffer from HNSCCs and 150 age-sex matched healthy controls were recruited in this study. Genomic DNA was extracted from white blood cells of all participants. Restricted fragment length polymorphisms (RFLP)-PCR was performed using site specific primers to determine the genotypes in each position. RESULTS Statistical analyses indicated no significant differences in the frequencies of genotypes, alleles as well as haplotypes between patients and controls (P > 0.05), however, haplotype combination differed significantly between two groups. GCC/GCT, GCC/GCC and GCT/GCC were higher in the HNSCC patients than the control group (P < 0.05). On the other hand, in the controls, GCT/GCT, GCT/ACC, GCT/ACT and ACC/GCT were more frequent. No significant association was found with various HNSCC clinicopathological characteristics. DISCUSSION Our results suggested that although PD-1 gene polymorphisms at three investigated positions are not solely associated with susceptibility to HNSCCs, haplotype combinations emerged from these three loci may render susceptibility.

Abstract
Primary hepatitis C virus infection might be spontaneously cleared or become chronic. Polymorphisms in immune regulatory genes might influence the outcome. The aim of this study was to determine the frequency of genotypes and alleles of PD-1.3 and PD-1.5 gene loci in HCV infected patients and their association with the disease outcome. In this study 167 patients with chronic hepatic C and 42 individuals whose infection was spontaneously cleared, and a healthy control group comprising of 300 participants were included. The presence of chronic or spontaneously cleared infection amongst the participants was determined in advance by serologic and molecular methods. Genomic DNA was extracted using salting out method. PD-1 gene polymorphisms assay was performed using PCR-RFLP method. The frequency of alleles of PD-1.3 gene locus was significantly higher in the spontaneously cleared HCV infected group (P = 0.03) as well as the healthy control group (P = 0.04) in comparison to the chronic infected participants. In the case of PD-1.5 locus, there was no association between the frequency of inherited genotype or alleles and HCV infection outcome amongst the three groups. Haplotype analysis showed no statistically significant differences in the frequencies of different haplotypes between the three studied groups. Our finding collectively inferred that individuals with A allele at PD-1.3 locus might clear HCV infection more frequently than those with T allele. Instead, polymorphisms at PD-1.5 locus as well as haplotypes emerged from PD-1.3 G/A and PD-1.5 C/T might not be significant in the HCV infection outcome.

Abstract
Visceral leishmaniasis (VL) or kala-azar, the most severe form of the disease, is endemic in more than eighty countries across the world. To date, there is no approved vaccine against VL in the market. Recent advances in reverse vaccinology could be promising approach in designing the efficient vaccine for VL treatment. In this study, an efficient multi-epitope vaccine against Leishmania infantum, the causative agent of VL, was designed using various computational vaccinology methods. Potential immunodominant epitopes were selected from four antigenic proteins, including histone H1, sterol 24-c-methyltransferase (SMT), Leishmania-specific hypothetical protein (LiHy), and Leishmania-specific antigenic protein (LSAP). To enhance vaccine immunogenicity, two resuscitation-promoting factor of Mycobacterium tuberculosis, RpfE and RpfB, were employed as adjuvants. All the aforesaid segments were joined using proper linkers. Homology modeling, followed by refinement and validation was performed to obtain a high-quality 3D structure of designed vaccine. Docking analyses and molecular dynamics (MD) studies indicated vaccine/TLR4 complex was in the stable form during simulation time. In sum, we expect our designed vaccine is able to induce humoral and cellular immune responses against L. infantum, and may be promising medication for VL, after in vitro and in vivo immunological assays.

Abstract
Vaccines are one of the most significant achievements in medical science. However, vaccine design is still challenging at all stages. The selection of antigenic peptides as vaccine candidates is the first and most important step for vaccine design. Experimental selection of antigenic peptides for the design of vaccines is a time-consuming, labor-intensive and expensive procedure. More recently, in the light of computer-aided biotechnology and reverse vaccinology, the precise selection of antigenic peptides and rational vaccine design against many pathogens have developed. In this study, the whole proteome of Leishmania infantum was analyzed using a pipeline of algorithms. From the set of 8045 proteins of L. infantum, sixteen novel antigenic proteins were derived using a hierarchical proteome subtractive analysis. These novel vaccine targets can be utilized as top candidates for designing the new prophylactic or therapeutic vaccines against visceral leishmaniasis. Significantly, all the sixteen novel vaccine candidates are non-allergen antigenic proteins that have not been used for the design of vaccines against visceral leishmaniasis until now.

Abstract
Cancer is the major cause of morbidity and mortality worldwide. Hydroxycinnamic acids (HCAs) are naturally occurring compounds and their alkyl esters may possess enhanced biological activities. We evaluated C4, C14, C16, and C18 alkyl esters of p-coumaric, ferulic, sinapic, and caffeic acids (19 compounds) for their cytotoxic activity against four human cancer cells and also examined their effect on cell cycle alteration and apoptosis induction. The tetradecyl (1c) and hexadecyl (1d) esters of p-coumaric acid and tetradecyl ester of caffeic acid (4c), but not the parental HCAs, were selectively effective against MOLT-4 (human lymphoblastic leukemia) cells with IC50 values of 0.123 ± 0.012, 0.301 ± 0.069 and 1.0 ± 0.1 μM, respectively. Compounds 1c, 1d, and 4c significantly increased apoptotic cells in sub-G1 phase and activated the caspase-3 enzyme in MOLT-4 cells. Compound 1c was 15.4 and 23.6 times more potent than doxorubicin and cisplatin, respectively, against the drug resistant MES-SA-DX5 uterine sarcoma cells. These p-coumarate esters were several times less effective against NIH/3T3 fibroblast cells. Docking studies showed that 1c may cause cytotoxicity by interaction with carbonic anhydrase IX. In conclusion, long chain alkyl esters of p-coumaric acid are promising scaffolds for selective apoptosis induction in cancer cells.

Abstract
Programmed death-1 (PD-1) negatively regulates the immune response. The aims of this study were to assess the association of two single nucleotide polymorphisms in the PD-1 gene, PD-1.5 (+7785 C/T-rs2227981) and PD-1.3 (+7146 G/A- rs11568821), with benign and malignant brain tumors. Patients with brain tumors (96 patients with benign and 56 with malignant brain tumors) and 150 healthy control individuals were included. PCR-RFLP was performed for genotyping. It was revealed that the genotype and allele frequencies of PD-1.5 C/T polymorphism were significantly different between all brain tumor patients and the control group. The frequencies of the CT genotype and T allele were higher in brain tumor patients. In contrast, the frequency of PD-1.3 G/A genotypes and alleles showed no significant difference between all brain tumor patients and controls. Patients were then divided into malignant and benign groups. The results revealed a significant difference in both patients groups compared with the controls only at PD-1.5 C/T position. Arlequin analysis showed the GC haplotype was the most frequent haplotype in the whole group of patients and controls, and the GT haplotype was significantly different between patient and control groups. In conclusion, we demonstrate that PD-1.5 C/T polymorphism, but not PD-1.3 G/A, is associated with brain tumors in Iranian patients.

Abstract
PURPOSE PD-1 receptor is a co-signaling molecule with an important role in regulation of T-lymphocyte activity. Correlation between PD-1 gene (PDCD1) polymorphisms and some immune-related diseases has been reported before. In current study, we aimed to investigate the association of PD-1 polymorphisms at positions +7146 G/A (PD-1.3) and +7785 C/T (PD-1.5), as well as the emerged haplotypes with susceptibility to thyroid carcinoma. METHODS One hundred five patients with confirmed thyroid cancer and 160 healthy individuals as control group were enrolled. Genotypes were identified using PCR-RFLP and nested PCR-RFLP methods. Results were analyzed by Arlequin and SPSS software packages. RESULTS Analysis revealed a significant increase in the frequency of PD-1.5 mutant T allele and heterozygous CT genotype in patients with thyroid cancer in comparison with controls [79 (37.7%) vs. 71 (22.2%), and 51 (48.6%) vs. 51 (31.9%), p = 0.0001 and p = 0.009, receptively]. CC genotype at this position observed to be significantly higher among controls than the patients [99 (61.9%) vs. 40 (38.1%), p = 0.0002]. There were no significant differences in the frequencies of genotypes and alleles at locus PD-1.3 between patients and control group. Despite this, GT haplotype emerged from both positions (PD-1.3 G and PD-1.5 T) has also been observed with significant increased frequency between patients and controls [70 (36.8%) vs. 71 (22.2%), p = 0.0005]. CONCLUSION As the first study to investigate two mentioned polymorphisms in thyroid cancer, current study confirmed the association of PD-1.5 C/T polymorphism and a haplotype resulted from both loci, PD-1.3 and PD-1.5, with susceptibility of Iranians to thyroid cancer.

Abstract
BACKGROUND Cytotoxic CD8+ T cells, as essential parts of the adaptive immune system, play pivotal roles in anti-tumor immune responses. It is well documented that cytokine expression profiles and activation status of these cells during anti-tumor immune responses affect the outcome of host-tumor interaction. OBJECTIVE To investigate the percentages of CD8+ lymphocytes and their subsets in tumor draining lymph nodes of patients with bladder cancer. METHODS Forty-five patients with bladder cancer, candidate for radical cystectomy, were recruited. Mononuclear cells were isolated from draining lymph nodes using Ficoll-Hypaque gradient centrifugation, and were activated by PMA/Ionomycin in the presence of Golgi inhibitors. The cells were then permeabilized and stained with appropriate flourochrome conjugated antibodies against CD3, CD8, IFN-γ, IL-17 and IL-4 molecules. Data were collected on a four-color flow cytometer and analyzed by CellQuestPro software. RESULTS Despite no difference in the frequency of IL-17 producing CD8+ (Tc17) lymphocytes, the mean expression of IL-17 in this subset was significantly elevated in high-grade patients (p=0.011). The percentage of double positive IFN-γ/IL-17 CD8+ lymphocytes was also significantly increased in node positive patients compared to node negative ones (p=0.046). Our results also demonstrated that the percentage of IFN-γ producing CD8+ (Tc1) lymphocytes was significantly increased in the patients with higher histological grade compared to those with lower ones (p=0.038). CONCLUSION IFN-γ and IL-17 producing CD8+ T cells may increase in advanced stages of bladder cancer, but their correlation with tumor prognosis remains to be investigated.

Abstract
BACKGROUND Colorectal cancer is one of the most common cancers worldwide. Viruses including human papillomavirus (HPV) have been reported to be associated with different cancers but any association with colorectal cancers remains controversial. AIM To evaluate any association between HPV infection and adenocarcinoma of the colon and adenomatous polyps. MATERIALS AND METHODS Paraffin-embedded tissue specimens of 70 colorectal adenocarcinomas, 70 colorectal adenomatous polyps, and 70 colorectal normal tissues were subjected to DNA extraction. The quality of the extracted DNA was confirmed by amplification of a β-globin fragment using polymerase chain reaction (PCR). PCR using specific primers were performed to detect HPV DNA. Specific primers targeting the E6 region of the HPVs 16 and 18 were used for genotyping. RESULTS HPV DNA was detected in 2 (2.85%) out of 70 adenocarcinoma colorectal tissues and 4 (5.71%) out of 70 adenomatous colorectal tissues. All normal colorectal tissues were negative for HPV DNA. HPV-16 was the most predominant genotype (5 sample) followed by HPV-18 (4 sample). Despite the above observations, statistical analyses indicated no significant differences in the frequencies of HPV positive subjects between the cancerous and normal samples. CONCLUSIONS Although the differences observed in the frequencies of HPV positive cases in our study was not significant relative to those of control subjects, the fact of 6 positive samples among cancerous tissues, may still suggest a role of HPV in colorectal carcinogenesis. The study collectively indicated that some colorectal cancerous tissues are infected with high risk HPV genotype. The findings merit more investigation.

Abstract
BACKGROUND Melanoma differentiation-associated gene-7 (MDA-7)/interleukin-24 (IL-24), a unique tumor suppressor gene, has killing activity in a broad spectrum of cancer cells. Herein, plasmids producing mda-7 proteins fused to different RGD peptides (full RGD4C and shortened RGD, tRGD) were evaluated for apoptosis induction with a hepatocellular carcinoma cell line, Hep-G2. The study aim was to improve the apoptosis potency of mda-7 by tethering to RGD peptides. MATERIALS AND METHODS Three plasmids including mda-7, mda-7-RGD and mda-7-tRGD genes beside a control vector were transfected into Hep-G2 cells. After 72 hours incubation, cell viability was evaluated by MTT assay. In addition, the rate of apoptosis was analyzed by flow cytometry using PI/annexin staining. To detect early events in apoptosis, 18 hours after transfection, expression of the BAX gene was quantified by real time PCR. Modeling of proteins was also performed to extrapolate possible consequences of RGD modification on their structures and subsequent attachment to receptors. RESULTS AND CONCLUSIONS In MTT assays, while all mda-7 forms showed measurable inhibition of proliferation, unmodified mda-7 protein exhibited most significant effect compared to control plasmid (P<0.001). Again, flow cytometry analysis showed a significant apoptosis induction by simple mda-7 gene but not for those RGD-fused mda-7 proteins. These findings were also supported by expression analysis of BAX gene (P<0.001). Protein modelling analysis revealed that tethering RGD at the end of IL-24/Mda7 disrupt attachment to cognate receptor, IL-20R1/ IL-20R2. In conclusion, fusion of RGD4C and shortened RGD peptides to carboxyl terminal of mda7, not only reduce apoptosis property in vitro but also disrupt receptor attachment as demonstrated by protein modelling.

Abstract
BACKGROUND Salivary gland tumors are among malignancies that have high recurrence rate. Immune responses in salivary gland tumors have not been well elucidated. T helper type 1 (Th1) and Th2 cytokines have been reported to play a role in the outcome of head and neck cancers. OBJECTIVE To evaluate the serum levels of interferon gamma (IFN-γ), as the hallmark of Th1 cytokines, and interleukin-4 (IL-4), as the hallmark of Th2 cytokines, in patients with benign and malignant salivary gland tumors in comparison with healthy controls. METHODS Fifty patients with benign and 14 patients with malignant salivary gland tumors, as well as 23 healthy individuals were recruited. Serum levels of IFN-γ and IL-4 were measured using ELISA method. Nonparametric tests were used for data analysis. RESULTS Serum levels of IFN-γ and IL-4 were found not to be significantly different in patients compared to the control group (0.68±0.29 vs. 1.03±0.57pg/ml, p=0.58 for IFN-γ, 4.57±1.57vs. 4.41±1.31pg/ml, p=0.28 for IL-4). IFN-γ and IL-4 serum levels were also not significantly different between patients with benign and malignant salivary gland tumors (p=0.54 and p=0.86, respectively). CONCLUSION The systemic levels of IL-4 and IFN-γ seem not to be associated with salivary gland tumor in our study. Investigation of other cytokines produced by Th1 and Th2 cells are warranted.

Abstract
Thyroid cancer is the most common malignancy of the endocrine system, and genetic factors have been shown to be associated with its risk. Interleukin-18 (IL-18) is a pleiotropic pro-inflammatory cytokine that induces IFN-γ production and is involved in T helper type 1 development. To determine the role of IL-18 gene in thyroid cancer susceptibility, we conducted a case-control study, and genotyped five single nucleotide polymorphisms (SNPs) in IL-18 gene (-656 G/T (rs1946519), -607 C/A (rs1946518), and -137 G/C (rs187238) in the promoter region and +113 T/G (rs360718) and +127 C/T (rs360717) in 5'-untranslated region) in 105 patients with thyroid cancer and 148 healthy controls from Iranian population. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and allele-specific primer-PCR were used for genotyping. The association of different genotypes with thyroid cancer, tumor type, and the tumor stage was analyzed. Comparing all of the patient population with the controls, TT genotype at position -656 G/T was observed to be associated with a significantly increased risk of thyroid cancer [31/105 (30.1 %) vs 19/148 (13.1 %), p = 0.002, OR 2.90, CI 1.40-5.70]. No association with thyroid cancer was found at other positions (-607 C/A, -137 G/C, +113 T/G, and +127 C/T). Excluding the patients with medullary carcinoma, and including only the ones with thyroid cancer derived from the follicular epithelium, nearly the same results were observed regarding the genotypes at position -656 G/T. Furthermore, significantly decreased risk of thyroid cancer derived from the follicular epithelium was observed upon inheritance of the homozygote genotype (CC) at position +127 C/T (40/94 (42.5 %) versus 84/148 (56.8 %) in patients and controls, respectively (OR 0.56, 95 % CI for OR 0.32-0.98, p = 0.04). Haplotype analysis indicated that among 32 possible haplotypes, TAGTT haplotype frequency was significantly higher in patients than in controls [12/188 (6.4 %) vs 2/292 (0.7 %), p = 0.0008] and this difference resisted Bonferroni correction (n = 19) and significant level set at 0.003. Nearly the same results were observed after excluding the patients with medullary carcinoma. No association was found between the SNPs and the stage of tumor. Our results suggest the increased susceptibility to thyroid cancer in subjects with TT genotype at position -656 G/T of the promoter of IL-18 gene, as well as TAGTT haplotype emerged from five studied SNPs in IL-18 gene. The data also suggest that the inheritance of +127 CC genotype may protect individuals from thyroid cancer derived from follicular epithelium.

Abstract
OBJECTIVES Up to now, many researches have been performed to improve the antitumoral effect of melanoma differentiation-associated gene-7 (mda-7) protein. The purpose of our research was to construct 3 expression vectors producing mda-7 in fusion with RGD (Arginine-Glycine-Aspartic acid) peptide and evaluate their expression. MATERIALS AND METHODS mda-7 gene with two different RGD sequences was amplified by PCR then was cloned by TA-cloning system. The colonies including these genes were selected by blue-white screening, colony PCR, and sequencing, respectively. Afterward, the genes were sub-cloned into the expression vector following confirmation by colony PCR and sequencing. In addition, these constructs were transfected into 293 and Huh-7 cells for further expression analysis. The mda-7 gene expression was evaluated by RT-PCR and IF (immunofluorescence assay). DNA laddering test and trypan blue exclusion assays were performed to screen cytotoxicity of prepared plasmids. RESULTS Three different mda-7 genes with terminal RGD peptide were cloned correctly into the expression vectors and their expression was confirmed to be suitable by RT-PCR and IF assay. It was shown that expressions were limited to those transfected, GFP shining cells. No significant cytotoxicity was observed by simple assays in all plasmid treated cells. In expressing cells, all forms of mda-7 protein were localized mainly around ER prenuclear compartment while GFP protein was distributed evenly among them. CONCLUSION Theoretically RGD tagged mda-7 would be able to induce apoptosis with more specificity and stronger than the standard one, therefore, these new constructs may have the potential for further researches.

Abstract
OBJECTIVES FOXP3 gene is an X-linked gene that encodes FOXP3 protein, an essential transcription factor in CD4+CD25+FOXP3+ regulatory T (Treg) cells. We aimed, in the present study, to investigate the association of two FOXP3 polymorphisms, -2383 C/T (rs3761549) and IVS9+459 T/C (rs2280883), with lung cancer. MATERIALS AND METHODS In a case-control study we analyzed genotypes and alleles frequencies at -2383 C/T and IVS9+459 T/C positions in 156 patients with lung cancer and 156 age and sex matched healthy controls in Southern Iranian population, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods. The data were verified by direct automated DNA sequencing. RESULTS The frequency of -2383 T allele was significantly higher in the patients than in the control group (11.8% versus 5.9%, P-value=0.04, OR=2.13, 95%CI=1.04-4.54). T allele frequency at IVS9+459 T/C position was higher, compared to the controls, in the patients who presented the disease over 55 years old (69.9% versus 59.1%, P-value=0.04, OR=1.61, 95%CI=1.01-2.55) and also in SCLC patients (77.8% versus 59.1%, P-value=0.03, OR=2.42, 95%CI=1.05-5.59). No significant differences were found in the genotypes and haplotypes distributions between the cases and controls. A high degree of linkage disequilibrium was observed between two polymorphisms. CONCLUSION As the first study dealing with -2383 C/T and IVS9+459 T/C in lung cancer, our data conclusively suggest the association of -2383 T allele with susceptibility to lung cancer in Iranian population. The association of IVS9+459 T allele with susceptibility to lung cancer in old patients suggests the age-dependent effects of FOXP3 gene on cancer occurrence.

Abstract
BACKGROUND Seaweeds have proven to be a promising natural source of bioactive metabolites for drug development. OBJECTIVE This study aimed to monitor the ethanol extract of ten algae from the Persian Gulf and Oman Sea, for their in vitro cytotoxic activity on three human breast cancer cell lines. MATERIALS AND METHODS Three human breast cancer cell lines including MDA-MB-231(ER(-)), MCF-7(ER(+)), and T-47D (ER(+)) were treated by different concentrations of total ethanol (90%) algae extracts and the cytotoxic effects were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Doxorubicin (Ebewe, Austria) was used as a positive control. After 72 h of incubation, the cytotoxic effect of the algae was calculated and presented as 50%-inhibitory concentration (IC50). RESULTS The results indicated Gracilaria foliifera and Cladophoropsis sp. to be the most active algae in terms of cytotoxic effects on the investigated cancer cell lines. The IC50 values against MDA-MB-231, MCF-7, and T-47D cells were, respectively, 74.89 ± 21.71, 207.81 ± 12.07, and 203.25 ± 30.98 µg/ml for G. foliifera and 66.48 ± 4.96, 150.86 ± 51.56 and >400 µg/ml for Cladophoropsis sp. The rest of the algal extracts were observed not to have significant cytotoxic effects in the concentration range from 6.25 µg/ml to 400 µg/ml. CONCLUSION Our data conclusively suggest that G. foliifera and Cladophoropsis sp. may be good candidates for further fractionation to obtain novel anticancer substances. Moreover, stronger cytotoxic effects on estrogen negative breast cancer cell line (MDA-MB-231(ER(-))) in comparison to estrogen positive cells (MCF-7 and T-47D) suggest that the extract of G. foliifera and Cladophoropsis sp. may have an estrogen receptor/progesterone receptor-independent mechanism for their cellular growth inhibition.
