Background: Psoriasis is a multifactorial and inflammatory chronic skin disease indicated with T-cell-mediated keratinocyte hyper-proliferation. Demographic, epidemiological (family, twin), serological, and genetic studies have clearly demonstrated that psoriasis is a polygenic and multifactorial disease. Aim: The objectives of the study are; to determine the prevalence of the polymorphisms of FAS (Fas cell surface receptor gene) -671 A>G (rs:1800682) and FASLG (Fas ligand gene) -844 T>C (rs:763110), to investigate the serum levels of sFas and sFasL, and also to discover any relationship between gene polymorphisms and serum levels in psoriatic patients. Material and Methods: 50 treated and 69 untreated patients, and 140 healthy controls were included in the study. Polymorphisms were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. The serum levels were measured in randomly selected treated (39) and untreated (40) patients, also in 84 healthy controls using micro-ELISA technique. Results: There was no statistical difference between polymorphisms in the patient and control groups. However, sFas and sFasL levels in both treated and untreated patients were higher than that of the controls. Conclusion: The investigated FAS and FASLG polymorphisms were not found to be directly associated with the psoriasis. Elevated sFas and sFasL levels in psoriatic patients showed that these factors may possess a significant role in the pathogenesis of psoriasis.

Introduction: Lung carcinoma is characterized by uncontrollable division of respiratory system cells with detrimental and lethalconsequences on human health. Critical roles of microRNAs (miR) are scientifically approved in biological and pathologicalpathways, such as the role of miR-499 (rs3746444) in lung carcinomas. Thus, in this case-control investigation, we aimed toassess the probable relationship between miR-499C/T variant and the occurrence of lung carcinoma in Iranian population forthe first time. Methods: Genotype of miR-499 polymorphism was described by the Polymerase Chain Reaction-Restriction Fragment LengthPolymorphism (PCR-RFLP) assay in patients and healthy individuals. Following definite diagnosis of lung carcinoma, the bloodsamples were collected, and the DNA extraction was performed by Salting-Out method. Finally, data were analysed by SPSS (v.20) and the significant level was considered p-value<0.05. Results: Statistically, the frequency of combined genotypes of CC+CT were 83.33% and 35% and TT+CT were 100% and 92%in case and control individuals, respectively. Also, individuals with genotypes of TC (OR: 3.08, CI95%: 3.03-3.17, p<0.0001),TC+CC (OR: 0.10, CI95%: 0.05-0.23, p<0.0001), CC (OR: 0, CI95%: 0.00-0.60, p=0.0214), and TC (OR: 0.07, CI95%: 0.03-0.15, p<0.0001) represented statistically significant (p<0.05) differences lung carcinoma than those with TT, TT, TT+TC, andTT+CC genotypes, respectively. The frequency of miR-499C (78.5%) and miR-499T (21.5%) alleles were also statistically significantly(p<0.05) difference associated with lung carcinoma in patients than controls. Conclusion: In this study, a possible relationship among miR-499C/T polymorphism and lung carcinoma was detected in Iranianpopulation. Since this study was conducted for the first time, thus other supplementary assessments are needed for definiteconclusion.

Background & objectives: Various studies have suggested a correlation between Fas cell surface death receptor/Fas ligand (FAS/FASL) variants and multiple types of cancers. The present study aimed to investigate the association between FAS-670A/G and FASL-844C/T and the synergistic effects of both variants on the risk of gastric cancer (GC) in the Kurdish population of west of Iran. Methods: This study was conducted by polymerase chain reaction-restriction fragment length polymorphism technique using MvaI and BsrDI restriction enzymes in 98 GC patients and 103 healthy control individuals. Results: According to the obtained results, a significant association ( P =0.008) of FASL polymorphism among GC patients and the control group was detected. Furthermore, no significant differences were found in the FAS polymorphism frequencies between GC patients and the control group. Codominant and dominant models in FASL polymorphism showed significant protective effects against GC [odds ratio (OR)=0.307, 95% confidence interval (CI) (0.134-0.705), P =0.005; OR=0.205, 95% CI (0.058-0.718), P =0.013 and OR=0.295, 95% CI (0.129-0.673), P =0.004 for models of codominant CC vs . CT, codominant CC vs . TT and dominant, respectively]. Furthermore, the presence of both FAS-670G and FASL-844T alleles represented a significant protective effect against GC occurrence [OR=0.420, 95% CI (0.181-0.975), P =0.043]. Interpretation & conclusions: So far, we believe this is the first study, the results of which suggest that FASL gene variation and its synergistic effects with FAS gene could be associated with the risk of GC in the Kurdish population in the west of Iran.
