Abstract
The airway epithelium is exposed to numerous external irritants including infectious agents, environmental allergens, and atmospheric pollutants, releasing epithelial cytokines including thymic stromal lymphopoietin (TSLP), IL-33, and IL-25 and initiating downstream type 2 (IL-4, IL-13, and IL-5) and IgE-driven pathways. These pathways trigger the initiation and progression of allergic airway diseases, including chronic rhinosinusitis with nasal polyps (CRSwNP), allergic rhinitis (AR), and allergic asthma. However, the use of biological agents that target downstream cytokines, such as IL-5, IL-4, and IL-13 receptors and IgE, might not be sufficient to manage some patients successfully. Instead of blocking downstream cytokines, targeting upstream epithelial cytokines has been proposed to address the complex immunologic networks associated with allergic airway diseases. Osteopontin (OPN), an extracellular matrix glyco-phosphoprotein, is a key mediator involved in Th1-related diseases, including systemic lupus erythematosus, multiple sclerosis, inflammatory bowel disease, and rheumatoid arthritis. Emerging evidence, including ours, indicates that epithelial-cell-derived OPN also plays an essential role in Th2-skewed airway diseases, including CRSwNP, AR, and allergic asthma involving the Th17 response. Therefore, we reviewed the current knowledge of epithelial-cell-derived OPN in the pathogenesis of three type-2-biased airway diseases and provided a direction for its future investigation and clinical relevance.

Abstract
PURPOSE Osteopontin (OPN) is a phosphoglycoprotein, with a wide range of physiological and pathological roles. High expression of OPN promotes aggressive behavior, causes poor prognosis in tumor cells, and reduces the survival of patients. Since overexpression of OPN gives rise to radioresistance, the effects of the gene knock out using the CRISPR/Cas9 system in combination with radiation are emphasized. MATERIAL AND METHODS We used the CRISPR/Cas9 technique to knock out the OPN gene in the MDA-MB-231 cell line. After transfection, the cells were irradiated. The changes of the OPN mRNA levels, the apoptosis, and the differences in cell viability were assessed. RESULTS A significant reduction in the OPN expression was observed alone or along with irradiation. The knocked out gene alone increased apoptosis rate. The cell viability decreased to after knocking out of the OPN gene. The gene knocking-out combined with irradiation led to more decline of cell viability. CONCLUSION Our results demonstrated that after knocking out the OPN gene, the MDA-MB-231 cells showed a significant radiosensitivity. Therefore, the OPN knock out in combination with conventional radiotherapy, may become an efficient therapeutic target in the future.

Abstract
Asthma and chronic obstructive pulmonary disease (COPD) are characterised by chronic inflammation in the lung that is associated with airway obstruction. Inhaled therapy with a combination of corticosteroid and a long-acting β2-agonist is an effective anti-inflammatory medicine for asthma, but in patients with severe asthma and COPD fails to completely control these symptoms with current therapies. The inflammatory process in these diseases, which involves activation of the coagulation and fibrinolytic system in the lung, offers the opportunity for alternative anti-inflammatory therapies. In this study, we investigated the effects of anti-coagulants on lipopolysaccharide (LPS)-induced airway inflammation in mice. A/J mice were exposed to LPS, a bacterial endotoxin, intranasally and accumulation of inflammatory cells, TNF-α, C-X-C motif chemokine (CXCL) 1, and osteopontin in bronchoalveolar lavage fluid (BALF) was monitored by flow cytometry and an enzyme-linked immunosorbent assay. LPS exposure induced airway neutrophilia and accumulation of TNF-α, CXCL1, and osteopontin in BALF. This LPS-induced airway inflammation was not relieved using a corticosteroid, fluticasone propionate (FP), or a direct inhibitor of Factor Xa, rivaroxaban. In contrast, a direct thrombin inhibitor, dabigatran, inhibited LPS-induced airway neutrophilia and decreased inflammatory cytokine production in a dose dependent manner. Furthermore, combination of dabigatran and FP elicited stronger inhibition of LPS-induced airway inflammation. Therefore, these results suggest that dabigatran could be an effective new therapy for severe respiratory diseases.

Abstract
Objective Osteopontin (OPN) plays an important role in chronic airway remodeling and bronchial hyperresponsiveness. The association between OPN protein expression and asthma has been investigated extensively, but the results of these studies are inconsistent. The aim of this meta-analysis was to determine the relationship between OPN protein expression and asthma. Methods A systematic search was performed to identify published studies regarding the association between OPN protein expression and asthma. Studies with quantitative data were analyzed, and standardized mean differences were determined with 95% confidence intervals. Results Nine studies were included in this analysis, involving 706 patients with asthma and 332 healthy controls. The pooled data from these studies demonstrated that OPN protein expression was significantly higher in patients with asthma than in controls. There was no significant difference in OPN protein between allergic asthma and nonallergic asthma. Moreover, there was no obvious relationship between OPN protein expression and the severity of asthma. Conclusion The results of this meta-analysis suggested that OPN protein expression is significantly upregulated in patients with asthma, but that it does not correlate with the type or severity of asthma.

Abstract
Assessment and management of asthma is complicated by the heterogeneous pathophysiological mechanisms that underlie its clinical presentation, which are not necessarily reflected in standardized management paradigms and which necessitate an individualized approach to treatment. This is particularly important with the emerging availability of a variety of targeted forms of therapy that may only be appropriate for use in particular patient subgroups. The identification of biomarkers can potentially aid diagnosis and inform prognosis, help guide treatment decisions and allow clinicians to predict and monitor response to treatment. Biomarkers for asthma have been identified from a variety of sources, including airway, exhaled breath and blood. Biomarkers from exhaled breath include fractional exhaled nitric oxide, measurement of which can help identify patients most likely to benefit from inhaled corticosteroids and targeted anti-immunoglobulin E therapy. Biomarkers measured in blood are relatively non-invasive and technically more straightforward than those measured from exhaled breath or directly from the airway. The most well established of these are the blood eosinophil count and serum periostin, both of which have demonstrated utility in identifying patients most likely to benefit from targeted anti-interleukin and anti-immunoglobulin E therapies, and in monitoring subsequent treatment response. For example, serum periostin appears to be a biomarker for responsiveness to inhaled corticosteroid therapy and may help identify patients as suitable candidates for anti-IL-13 treatment. The use of biomarkers can therefore potentially help avoid unnecessary morbidity from high-dose corticosteroid therapy and allow the most appropriate and cost-effective use of targeted therapies. Ongoing clinical trials are helping to further elucidate the role of established biomarkers in routine clinical practice, and a range of other circulating novel potential biomarkers are currently being investigated in the research setting.

Abstract
Background. Osteopontin (OPN) has been proved to be associated with allergic airway inflammation. However, the roles of OPN and its regulation in childhood allergic rhinitis (AR) are poorly understood. Objective. This study aims to evaluate the expression of OPN and miR-181a in children with AR and their association with Th1/Th2 immune response. Methods. Children who suffered from AR were included along with control subjects. Serum was collected to examine the level of OPN and Th1/Th2 cytokines by enzyme-linked immunosorbent assay (ELISA) and the level of miR-181a by quantitative polymerase chain reaction (qPCR). Results. Children with AR had significantly higher serum levels of OPN and lower serum levels of miR-181a than healthy controls. Furthermore, serum levels of OPN were positively correlated with Th2 cytokine and negatively correlated with Th1 cytokine. On the contrary, miR-181a level had a negative correlation with IL-4/IL-5 and positive correlation with IFN-γ/IL-12. More importantly, there was also significant negative correlation between OPN and miR-181a. Conclusion. The OPN protein and miR-181a levels may serve as predictors of disease severity in childhood AR and appear to be promising targets for modulating AR.

Abstract
PURPOSE The aim of the study was to evaluate serum osteopontin (OPN) concentrations in patients with disseminated form of allergic contact dermatitis (ACD), and to assess the relationship between serum OPN level and disease severity. PATIENTS AND METHODS Twenty-four patients with numerous allergic contact dermatitis lesions and twenty-two age- and sex-matched healthy subjects as a control group were enrolled in the study. Serum osteopontin levels were measured in the ACD patients twice: in the acute stage and during disease remission by ELISA. RESULTS Serum OPN concentrations were significantly increased in patients with disseminated ACD examined in the acute stage as compared to healthy subjects and ACD patients during remission (p<0.01 and p<0.001, respectively). In the ACD patients with extensive skin lesions (EASI>10), OPN serum levels were significantly higher than in those with mild disease (EASI<10). CONCLUSIONS Acute disseminated ACD is characterized by elevated serum concentrations of osteopontin, with levels depending on ACD severity, which indicates its role in the elicitation phase of allergic contact dermatitis. The possibility of inhibition of OPN activity may create a new therapeutic perspective in severe forms of this troublesome skin disease.

Abstract
BACKGROUND The role of osteopontin (OPN) has not been elucidated in childhood asthma. OBJECTIVE Our purpose was to investigate whether OPN levels change due to allergic inflammation in pre-school and school-age children. METHODS In this prospective, cross-sectional study, 42 healthy children and a total of 51 children with asthma were recruited. OPN levels and its association with clinical and laboratory parameters were investigated in the study population. The asthma group were divided into two groups with respect to age, ≤ 5-years (n = 23) and >5-years (n = 28), and labelled Asthma Group 1 and Asthma Group 2, respectively. OPN levels were compared between subgroups. RESULTS Serum OPN levels were significantly higher in the asthma group when compared to the control group (p = 0.004). OPN levels were similar in Asthma Group 1 and control groups, whereas it was found to be higher in Asthma Group 2 (p>0.025, p = 0.001, respectively). In the >5-years age asthmatic group, OPN levels of the patients with allergic rhinitis (n = 15) were higher than those of the patients (n=13) without allergic rhinitis (p = 0.021). CONCLUSION The study underscores the relationship between childhood asthma and OPN as the first study in the literature. In this study we found that OPN, which plays a role in Th2 mediated inflammation, may also play a role in childhood asthma. The fact that OPN levels do not increase in preschool-age children with asthma might be due to the transient wheezing in this group.

Abstract
Osteopontin (OPN) is an acidic, noncollagenous matrix protein produced by the bone and kidneys. It is reportedly involved in bone resorption and formation. We examined the association between serum OPN levels and bone mineral density in postmenopausal women. Premenopausal women (n=32) and postmenopausal women (n=409) participated in the study. We measured serum osteopontin levels and their relationships with bone mineral density and previous total fragility fractures. The postmenopausal women had higher mean serum OPN levels compared to the premenopausal women (43.6±25.9 vs 26.3±18.6 ng/mL; P<0.001). In the postmenopausal women, high serum OPN levels were negatively correlated with mean lumbar bone mineral density (BMD) (r=-0.113, P=0.023). In a stepwise multiple linear regression model, serum OPN levels were associated with BMD of the spine, femoral neck, and total hip after adjustment for age, body mass index, smoking, and physical activity in postmenopausal women. However, serum OPN levels did not differ between postmenopausal women with and without fractures. Postmenopausal women exhibit higher serum OPN levels than premenopausal women and higher serum OPN levels were associated with low BMD in postmenopausal women.
