Correlation between lung neoplasm and serum level of osteopontin: A meta-analysis.

The aim of this meta-analysis was to evaluate the clinical significance of serum osteopontin (OPN) levels in lung neoplasm in patients to establish a novel diagnostic score model. Articles were identified by searching the PubMed, Web of Science, Google Scholar, China National Knowledge Infrastructure, and Wang Fang databases. Studies identified were pooled, and the standardized mean difference (SMD) and its corresponding 95% confidence interval (CI) were calculated.

Down-regulation of miR-150 induces cell proliferation inhibition and apoptosis in non-small-cell lung cancer by targeting BAK1 in vitro.

Non-small-cell lung cancer (NSCLC) is one of the most common causes of cancer-related death. Our investigations show that miR-150 is a typical microRNA that is overexpressed in human NSCLC. We characterized the effects of miR-150 overexpression in NSCLC cells and found that down-regulation of miR-150 expression inhibited cell proliferation and induced cell apoptosis in vitro; additionally, up-regulation of miR-150 levels had the opposite effect on tumor growth and progression.

Grape seed proanthocyanidin extract attenuates airway inflammation and hyperresponsiveness in a murine model of asthma by downregulating inducible nitric oxide synthase.

Allergic asthma is characterized by hyperresponsiveness and inflammation of the airway with increased expression of inducible nitric oxide synthase (iNOS) and overproduction of nitric oxide (NO). Grape seed proanthocyanidin extract (GSPE) has been proved to have antioxidant, antitumor, anti-inflammatory, and other pharmacological effects. The purpose of this study was to examine the role of GSPE on airway inflammation and hyperresponsiveness in a mouse model of allergic asthma.

[Inhibitory effects of apigenin on the expression of GATA-3 and Th2 cytokines in asthmatic mice].

Objective: To investigate the inhibitory effects and mechanism of apigenin (APG) on dominant response of Th2 cells in asthma model of mice.

Methods: Thirty-two 6-week-old healthy BALB/c mice, SPF grade, were randomly divided into four groups equally, the normal control group (A), the asthma model group (B), and the two APG groups (C and D) consisted of asthma model mice treated respectively with high-dose (20 mg/kg per day) and low-dose (2 mg/kg per day) APG given by dissolving in 1% dimethyl sulphoxide via intraperitoneal injection. The murine asthma model was established by ovalbumin (OVA) sensitization and provocation.

Apigenin inhibits allergen-induced airway inflammation and switches immune response in a murine model of asthma.

Many flavonoids were demonstrated to possess the antiallergic effect. Here we detected whether apigenin, a flavonoid, can attenuate allergen-induced airway inflammation and what is the possible mechanism in a murine model of asthma. Apigenin decreased the degree of the inflammatory cell infiltration, airway hyperresponsiveness, and total immunoglobulin E levels compared with the ovalbumin group.

Naringenin inhibits allergen-induced airway inflammation and airway responsiveness and inhibits NF-kappaB activity in a murine model of asthma.

Naringenin, a flavonoid, has antiinflammatory and immunomodulatory properties. We investigated whether naringenin could attenuate allergen-induced airway inflammation and its possible mechanism in a murine model of asthma. Mice were sensitized and challenged with ovalbumin.
