Background: β-catenin is a key component of the canonical Wnt pathway, which plays pivotal roles in malignant transformation and cancer progression. Several studies have reported the clinical significance of the expression level of β-catenin in different subcellular locations. This meta-analysis aimed to assess the prognostic value of β-catenin expression patterns in patients with non-small cell lung cancer (NSCLC).
Methods: PubMed and Embase databases were searched to identify all articles referring to the association between β-catenin expression level and outcomes of patients of NSCLC up to November 2016. We included eligible studies to summarize the extracted data in terms of pooled hazard ratios (HRs) and their 95% confidence intervals (95% CIs).
Results: A total of 24 studies published between 2000 and 2016 were eligible for this meta-analysis. The total number of patients with NSCLC included was 2,807. Pooled HRs and 95% CIs suggested that positive β-catenin expression in membrane was associated with higher survival rates (HR: 0.53; 95% CI: 0.32-0.87), whereas β-catenin expression in cytoplasm and nucleus had unfavorable impacts on survival rates with HR of 1.63 (95% CI: 1.34-1.99) and HR of 3.15 (95% CI: 1.97-5.05), respectively. But, there was no significant association between β-catenin expression in abnormal pattern with prognosis (HR: 1.38; 95% CI: 0.61-3.15). Publication bias was absent in all of the four outcomes. Sensitivity analysis revealed that the results of this meta-analysis were robust.
Conclusions: Reduced membranous β-catenin, positive expression of cytoplasmic or nuclear β-catenin is all correlated with poor prognosis, although we did not identify a significant association between abnormal β-catenin expression and clinical outcome of NSCLC patients. The meta-analysis suggested that membranous, cytoplasmic and nuclear β-catenin all could serve as an important prognosticator for patients with NSCLC.

Objective: TRIB3 has been confirmed to participate in and regulate biological metabolic activities in head and neck tumors such as nasopharyngeal carcinoma and oropharyngeal carcinoma, so the purpose of this study was to explore whether there is a correlation between TRIB3 and Laryngeal Squamous Cell Carcinoma (LSCC) and to preliminarily explore the biological characteristics of TRIB3 in LSCC.
Methods: TRIB3 expression in the LSCC was analyzed based on The Cancer Genome Atlas (TCGA) database. CCK-8 assay, Colony Formation Assay, wound healing assay, and Transwell assay were performed to investigate the roles of TRIB3 in the proliferation, invasion and metastasis of LSCC.
Development of translationally active cell lysates from different filamentous fungi for application in cell-free protein synthesis.

There is an enormous potential for cell-free protein synthesis (CFPS) systems based on filamentous fungi in view of their simple, fast and mostly inexpensive cultivation with high biomass space-time yields and in view of their catalytic capacity. In 12 of the 22 different filamentous fungi examined, in vitro translation of at least one of the two reporter proteins GFP and firefly luciferase was detected. The lysates showing translation of a reporter protein usually were able to synthesize a functional cell-free expressed unspecific peroxygenase (UPO) from the basidiomycete Cyclocybe (Agrocybe) aegerita.

Pulmonary arterial hypertension (PAH) is a syndrome characterized by increased pulmonary vascular resistance and elevated pulmonary artery pressure, ultimately leading to right heart failure and even death. Increasing evidence implicates the fat mass and obesity-associated protein (FTO) in various metabolic and inflammatory pathways; however, its role in pulmonary endothelial function and PAH remains largely unexplored. In this study, we examined the effects of endothelial cell-specific FTO knockout on PAH development.

Mapping the myomagnetic field of a straight and easily accessible muscle after electrical stimulation using triaxial optically pumped magnetometers (OPMs) to assess potential benefits for magnetomyography (MMG). Approach: Six triaxial OPMs were arranged in two rows with three sensors each along the abductor digiti minimi (ADM) muscle. The upper row of sensors was inclined by 45° with respect to the lower row and all sensors were aligned closely to the skin surface without direct contact.
