FOXA2, a member of the forkhead family of transcription factors, plays essential roles in liver development and bile acid homeostasis. In this study, we report a 2.8 Å co-crystal structure of the FOXA2 DNA-binding domain (FOXA2-DBD) bound to a DNA duplex containing a forkhead consensus binding site (GTAAACA). FOXA2-DBD adopts the canonical winged-helix fold, with helix H3 and wing 1 regions mainly mediating the DNA recognition. Although the wing 2 region was not defined in the structure, isothermal titration calorimetry (ITC) assays suggested that this region was required for optimal DNA binding...

Cytotoxin-associated gene A (CagA) is one of the most important virulence factors of Helicobacter pylori, and serves a role in H. pylori‑mediated tumorigenesis in gastric cancer. However, the underlying molecular mechanism remains to be elucidated. The present study aimed to investigate the effects of CagA on the proliferation and apoptosis of GES‑1 cells, and the underlying mechanism. A CagA eukaryotic expression plasmid was constructed and transfected into GES‑1 cells. The mRNA and protein levels of CagA, tumor necrosis factor receptor‑associated factor 1 (TRAF1) and tumor necrosis factor receptor superfamily member 9 (4‑1BB) were determined using the reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively...

Aberrant overexpression of the transcription/translation factor Y-box-binding protein (YB-1) is associated with poor prognosis of lung adenocarcinoma, however the underlying mechanism by which YB-1 acts has not been fully elucidated. Here, we reported that inhibition of YB-1 diminished proliferation, migration and invasion of lung adenocarcinoma cells. Interestingly, we identified metastasis associated in colon cancer-1 (MACC1) as a target of YB-1. Depletion of YB-1 markedly decreased MACC1 promoter activity and suppressed the MACC1/c-Met signaling pathway in lung adenocarcinoma cells...

Due to the low strength and high brittleness of 45S5 Bioglass(®), it is still a great challenge for the three-dimensional porous 45S5 Bioglass(®) to treat mechanically required loaded bone defects. Therefore, 45S5 Bioglass(®)-derived bioactive glass-ceramic (BGC) porous scaffolds were fabricated at a low temperature sintering condition with and without the addition of 4% low-melting ZnO/B2O3 (ZB) bioactive glass as a reinforcing agent and using 350- or 500 μm paraffin microspheres as a porogen. The pore structure characterization for the scaffolds indicated that the scaffolds containing 4% ZB had very good macroporous structures of ∼313 and ∼448 μm in pore size and over 70% porosity with appreciable strength (>15 MPa), which was about four times higher than that those manufactured without ZB and with 350 μm porogen scaffolds...

The amyloid precursor like protein-1 (APLP1) is a member of the amyloid precursor protein (APP) family in mammals. While many studies have been focused on the pathologic role of APP in Alzheimer's disease, the physiological functions of APLP1 have remained largely elusive. Here we report that ectopic expression of APLP1 in Drosophila induces cell migration, which is suppressed by the loss of JNK signaling and enhanced by the gain of JNK signaling. APLP1 activates JNK signaling through phosphorylation of JNK, which up-regulates the expression of matrix metalloproteinase MMP1 required for basement membranes degradation and promotes actin remodeling essential for cell migration...

The squalene epoxidase (SE) gene from the biosynthetic pathway of ganoderic acid (GA) was cloned and overexpressed in Ganoderma lingzhi. The strain that overexpressed the SE produced approximately 2 times more GA molecules than the wild-type (WT) strain. Moreover, SE overexpression upregulated lanosterol synthase gene expression in the biosynthetic pathway. These results indicated that SE stimulates GA accumulation. Then, the SE and 3-hydroxy-3-methylglutaryl coenzyme A (HMGR) genes were simultaneously overexpressed in G...

Even though salbutamol (SAL) had remarkable effects on the enhancement of growth rate and carcass composition in different livestock species such as cattle, pigs, sheep and poultry, it was banned as a growth promoter because of its adverse effects on health. However, the specific mechanism by which salbutamol enhances growth efficiency remains unknown. In this study, Bama pigs were randomly allocated to receive salbutamol (5 mg/kg) for 30 or 60 days and were compared with untreated pigs. Pigs treated with salbutamol demonstrated enhanced growth rates and carcass composition; however, they showed deterioration in blood biochemical indices and organ development...

The development of highly active, cost-effective, environmentally friendly and stable g-C3N4 based photocatalysts for H2 evolution is one of the most anticipated potential pathways for future hydrogen utilization. Herein, a facile gaseous bubble template approach was designed to prepare large-scale thin g-C3N4 nanosheets (g-C3N4 NSs) using melamine and ammonium sulphate as the bubble template. Through distinctive structural improvements for a large bandgap, excellent electron mobility, prolonged lifetime of the photogenerated charge carriers and a high specific surface area with highly accessible potential reaction sites, the as-synthesized g-C3N4 NSs demonstrated a high photocatalytic hydrogen evolution rate of 9871 μmol h(-1) g(-1) and efficient photocatalytic degradation of Rhodamine B (RhB) and phenol under simulated solar light irradiation...
