TNF-α is a central proinflammatory cytokine contributing to malignant tumor progression in tumor microenvironment. In this study, we found the upregulation of miR-105 in colorectal cancer was associated with aggressive phenotype, and the enhanced expression of miR-105 was required for TNF-α-induced epithelial-mesenchymal transition (EMT). The expression of miR-105 was remarkably stimulated by TNF-α in a time-dependent manner using real-time qPCR analysis. Inhibition of miR-105 remarkably weakened the aggressive effects of TNF-α through preventing the activation of NF-κB signaling and the initiation of EMT...

BACKGROUND: Regular fish and omega-3 consumption may have several health benefits and are recommended by major dietary guidelines. Yet, their intakes remain remarkably variable both within and across populations, which could partly owe to genetic influences. OBJECTIVE: To identify common genetic variants that influence fish and dietary eicosapentaenoic acid plus docosahexaenoic acid (EPA+DHA) consumption. DESIGN: We conducted genome-wide association (GWA) meta-analysis of fish (n = 86,467) and EPA+DHA (n = 62,265) consumption in 17 cohorts of European descent from the CHARGE (Cohorts for Heart and Aging Research in Genomic Epidemiology) Consortium Nutrition Working Group...

Avian influenza viruses (AIVs) such as H5N1 and H7N9 are a great threat to poultry economics and public health. Vaccination can effectively inhibit the spread of AIV in poultry, which is also a viable strategy for controlling virus transmission from poultry to human. Adjuvants that are commonly used in current inactivated vaccines to provide stronger anti-AIV immune responses are often limited in their capacity to quantitatively induce both humoral and cellular immune responses. Herein, we assessed the levels of immune responses generated by a vaccine formulation comprising inactivated H5N1 antigen and synthetic peptides covering conserved CD4+, CD8+ T cell, and B cell epitopes...

The clinical evidence indicated that cyclophosphamide (CPD), one of the chemotherapy drugs, caused severe deteriorations in bones of cancer patients. However, the exact mechanisms by which CPD exerts effects on bone remodeling is not yet fully elucidated. Therefore, this study was performed to investigate the role and potential mechanism of CPD in osteoblastogenesis and osteoclastogenesis. Here it was found that CPD treatment (100mg/kg/day) for 7 days led to osteoporosis phenotype in male mice. CPD inhibited osteoblastogenesis as shown by decreasing the number and differentiation of bone mesenchymal stem cells (MSCs) and reducing the formation and activity of osteoblasts...

The in vivo fate of nanocrystals is a controversial topic, i.e. dissolving versus integral absorption through the intestinal membrane. This is due to the lack of functional strategies to identify integral nanocrystals. In this study, the in vivo fate of quercetin hybrid nanocrystals (QT-HNCs) via the oral route is explored by physically embedding an environment-responsive probe in the crystal lattices of quercetin. The specific property of the probe is the water-initiated aggregation-caused quenching (ACQ) ability, by which integral QT-HNCs can be self-discriminated...

Atomic motion at grain boundaries is essential to microstructure development, growth and stability of catalysts and other nanostructured materials. However, boundary atomic motion is often too fast to observe in a conventional transmission electron microscope (TEM) and too slow for ultrafast electron microscopy. Here, we report on the entire transformation process of strained Pt icosahedral nanoparticles (ICNPs) into larger FCC crystals, captured at 2.5 ms time resolution using a fast electron camera. Results show slow diffusive dislocation motion at nm/s inside ICNPs and fast surface transformation at μm/s...

ATP is mainly generated by glycolysis in pluripotent stem cells (PSCs) and is consumed to maintain cell viability. Differences in mitochondrial activity among induced (i)PSCs with different degrees of pluripotency are poorly understood. In this study, by comparing gene expression and mitochondrial activity among iPSCs with different degrees of pluripotency, we found that mitochondrial complex I gene expression, complex I activity, and cellular ATP levels were much higher in fully pluripotent stem cell lines than in partially pluripotent stem cell lines...
