Abstract
Type 1 diabetes (T1D) is an autoimmune disease that is typically diagnosed in children. The aim of the present study was to identify potential genes involved in the pathogenesis of childhood T1D. Two datasets of mRNA expression in children with T1D were obtained from the Gene Expression Omnibus (GEO). Differentially expressed genes (DEGs) in children with T1D were identified. Functional analysis was performed and a protein‑protein interaction (PPI) network was constructed, as was a transcription factor (TF)‑target network. The expression of selected DEGs was further assessed using reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis. Electronic validation and diagnostic value analysis of the identified DEGs [cytokine inducible SH2 containing protein (CISH), SR‑related CTD associated factor 11 (SCAF11), estrogen receptor 1 (ESR1), Rho GTPase activating protein 25 (ARHGAP25), major histocompatibility complex, class II, DR β4 (HLA‑DRB4) and interleukin 23 subunit α (IL23A)] was performed in the GEO dataset. Compared with the normal control group, a total of 1,467 DEGs with P<0.05 were identified in children with T1D. CISH and SCAF11 were determined to be the most up‑ and downregulated genes, respectively. Heterogeneous nuclear ribonucleoprotein D (HNRNPD; degree=33), protein kinase AMP‑activated catalytic subunit α1 (PRKAA1; degree=11), integrin subunit α4 (ITGA4; degree=8) and ESR1 (degree=8) were identified in the PPI network as high‑degree genes. ARHGAP25 (degree=12), HNRNPD (degree=10), HLA‑DRB4 (degree=10) and IL23A (degree=9) were high‑degree genes identified in the TF‑target network. RT‑qPCR revealed that the expression of HNRNPD, PRKAA1, ITGA4 and transporter 2, ATP binding cassette subfamily B member was consistent with the results of the integrated analysis. Furthermore, the results of the electronic validation were consistent with the bioinformatics analysis. SCAF11, CISH and ARHGAP25 were identified to possess value as potential diagnostic markers for children with T1D. In conclusion, identifying DEGs in children with T1D may contribute to our understanding of its pathogenesis, and such DEGs may be used as diagnostic biomarkers for children with T1D.

Abstract
Background Sarcoidosis is a systemic inflammatory disease of unknown etiology. Osteopontin (SPP1, OPN) is an extra cellular matrix glycoprotein and cytokine with a known role in granuloma formation and in autoimmune and inflammatory diseases. Objective To determine whether plasma OPN levels are elevated in patients with sarcoidosis and compare the frequency of four single nucleotide polymorphism (SNPs) variants in the OPN gene in sarcoidosis patients compared to healthy controls. Methods Demographic and clinical information, radiological studies and pulmonary function tests were evaluated in 113 patients with sarcoidosis and in 79 healthy controls. Blood samples were analyzed for SNPs of the OPN gene and for plasma OPN and CRP levels. Association between clinical features of disease and OPN levels as well as SNP frequencies was determined. Results Plasma OPN levels were higher in sarcoidosis patients than in healthy subjects, (median: 217 vs 122ng/ml, p<0.001). Area under the curve for receiver operator curves (ROC) was 0.798 (0.686–0.909 95% CI.) No differences were observed between sarcoidosis patients and controls in the frequency of any of the SNPs evaluated. Presence of lung parenchymal involvement was associated with SNP distribution at rs1126772 (p = 0.02). We found no correlation between SNPs distribution and plasma OPN levels. Conclusions Osteopontin protein levels are elevated in sarcoidosis. We found no evidence for an association between SNPs on the osteopontin gene and plasma OPN levels or the presence of sarcoidosis, however, an association between genotype and several phenotypic clinical parameters of disease was observed.

Abstract
Osteopontin (OPN) regulates the immune response at multiple levels. Physiologically, it regulates the host response to infections by driving T helper (Th) polarization and acting on both innate and adaptive immunity; pathologically, it contributes to the development of immune-mediated and inflammatory diseases. In some cases, the mechanisms of these effects have been described, but many aspects of the OPN function remain elusive. This is in part ascribable to the fact that OPN is a complex molecule with several posttranslational modifications and it may act as either an immobilized protein of the extracellular matrix or a soluble cytokine or an intracytoplasmic molecule by binding to a wide variety of molecules including crystals of calcium phosphate, several cell surface receptors, and intracytoplasmic molecules. This review describes the OPN structure, isoforms, and functions and its role in regulating the crosstalk between innate and adaptive immunity in autoimmune diseases.

Abstract
Behçet syndrome (BS) is a multisystem vasculitis that is most active during young adulthood, causing serious disability and significant impairment in quality of life. Differences in the disease course, severity, and organ involvement between patients, depending on the age at presentation and sex, makes it impossible to determine a single management strategy. The diversity and variability in the outcome measures used in clinical trials in BS makes it difficult to compare the results or inform physicians about the best management strategy for individual patients. There is a large unmet need to determine or develop validated outcome measures for use in clinical trials in BS that are acceptable to researchers and regulatory agencies. We conducted a systematic review to describe the outcomes and outcome measures that have been used in clinical trials in BS. This review revealed the diversity and variability in the outcomes and outcome measures and the lack of standard definitions for most outcomes and rarity of validated outcome tools for disease assessment in BS. This systematic literature review will identify domains and candidate instruments for use in a Delphi exercise, the next step in the development of a core set of outcome measures that are properly validated and widely accepted by the collaboration of researchers from many different regions of the world and from different specialties, including rheumatology, ophthalmology, dermatology, gastroenterology, and neurology.

Abstract
UNLABELLED This study aims to investigate the role of osteopontin (OPN) genetic polymorphisms in the occurrence of left ventricular hypertrophy (LVH) in Chinese patients with essential hypertension (EH). A total of 1,092 patients diagnosed with EH were recruited. Three single nucleotide polymorphisms (SNP) on the promoter region of the OPN gene, including -66T/G, -156G/GG, and -443C/T were genotyped. The serum thrombin-cleaved OPN levels were studied. Patients were divided into LVH+ (n = 443) and the LVH- (n = 649) groups. We found that none of the studied SNPs in the OPN gene was associated with the risk and severity of LVH. The SNPs in the OPN gene did not correlate with the serum OPN levels. However, the serum thrombin-cleaved OPN levels were found to be an independent risk factor for LVH in the EH patients. Multivariate logistic regression analysis showed that serum thrombin-cleaved OPN levels were independently associated with the development of LVH (adjusted OR = 2.47, 95 % CI 1.56-4.01, adjusted P < 0.001). In vitro studies showed that the thrombin-cleaved OPN treatment increased the protein content per cell, the cardiomyocyte surface size, and the expression level of atrial natriuretic peptide protein in a dose-dependent manner. The thrombin-cleaved OPN serum level, but not OPN gene polymorphism, is associated with the development of LVH in EH patients. KEY MESSAGES Serum OPN is related to LVH incidence in essential hypertension subjects. OPN stimulates cardiomyocyte hypertrophy in vitro. OPN SNPs are not related to LVH incidence.

Abstract
BACKGROUND Failure in self-tolerance towards β-cells in diabetes mellitus (DM) pathogenesis involves a series of complex events that are governed by environmental and genetic factors. Considering the importance of osteopontin (OPN) in T-helper-1 (Th1) cells development, the aim of this study was to evaluate the serum level and gene polymorphism of OPN in Iranian Type 1 diabetic (T1DM) children. METHODS In this case-control study, 87 T1DM children and 86 healthy ones were enrolled. Blood samples of both groups were checked for OPN level. The single nucleotide polymorphisms (SNP) were genotyped by RFLP analysis for OPN rs1126772, its receptor integrin α4 (ITGA4) rs 1449263, and CD44 rs8193. RESULTS Serum levels of OPN in diabetic children were significantly higher in cases compared to the control group (p=0.023), but there was no significant relationship between OPN rs1126772 (p=0.79), its receptor integrin α4 (p=0.31), and CD44 rs8193 (p=0.45), and T1DM. CONCLUSION Higher amounts of OPN were seen in T1DM children. It is assumed that OPN might have inducing effects on T1DM development, particularly when genetically susceptible individuals are predisposed by an environmental insult. However, the 3 SNPs of OPN and its receptors did not show noticeable association with T1DM. The power of our study (~19%) was insufficient to observe any significant statistical difference between the groups; moreover, this study does not exclude the possibility of association of other SNPs of OPN and its receptors with this disease, and more studies are needed to clarify the issue.

Abstract
No previous study has reported the association of osteopontin polymorphisms with nasopharyngeal carcinoma (NPC) risk. We aimed to investigate the association in a Chinese population. Four variants of osteopontin, rs11730582, rs1126772, rs9138, and rs4754 polymorphisms, were assessed in a case-control study which consists of 108 NPC patients and 210 health controls, by using polymerase chain reaction--restriction fragment length polymorphism method. Serum osteopontin levels were measured by enzyme-linked immunosorbent assay. The serum osteopontin levels were significantly higher in NPC patients than those in controls (P<0.01). Carriers of CC and CT genotype of rs11730582 presented lower serum osteopontin levels than those of TT genotype carriers (P<0.05). Genotypes CT and CT+CC of rs11730582 were associated with the risk of NPC (CT:OR = 0.57, 95%CI = 0.34-0.94; CC+CT:OR = 0.54, 95%CI = 0.34-0.87). Haplotype analysis revealed that haplotype T-A-A-C of rs11730582, rs1126772, rs9138, and rs4754 was associated with NPC risk (OR = 0.49, 95%CI = 0.27-0.86). Stratification analysis showed that genotypes CT and CT+CC of rs11730582 were associated with tumor stage and lymph node metastasis (P<0.05). No associations were found between rs1126772, rs9138, and rs4754 polymorphisms and NPC risk (P>0.05). The variant rs11730582 of osteopontin is associated with NPC risk. It potentially serves as a genetic marker of NPC predisposition.

Abstract
AIM Osteopontin (OPN) is a multifunctional molecule highly expressed in chronic inflammatory and autoimmune diseases. We aimed to assess the plasma OPN levels in Behcet's disease (BD) patients and identify potential associations between these levels with disease activity, severity and clinical manifestations with special emphasis on vascular affection. METHODS We studied 55 BD patients and 31 age- and gender-matched healthy controls. Demographic, clinical and serological data were prospectively assessed. Activity and severity of BD were assessed using clinical scores and laboratory parameters. Plasma OPN levels were measured using enzyme-linked immunosorbent assay (ELISA). RESULTS Plasma OPN levels were significantly higher in patients with BD compared to healthy controls (p < 0.000). The means for plasma OPN levels in active and inactive BD patients were significantly higher than that for the normal controls (with p < 0.000 and p = 0.002 respectively). The mean OPN levels significantly associated with the BD clinical severity score from mild to severe (p = 0.011). BD patients with vascular involvement had significant elevation of plasma OPN levels than those without (P = 0.03). OPN levels positively correlated with severity score, IL6, hsCRP, ESR, leucocytes count and neutrophil count. CONCLUSION Plasma OPN levels were higher in BD patients than in healthy controls and were found to be associated with disease activity, severity and vascular involvement. To confirm our results we propose that larger scale, multicentre studies with longer evaluation periods are needed.
