Abstract
Eribulin is indicated in the EU for advanced/metastatic breast cancer patients following ≥1 prior chemotherapy for advanced disease, and anthracycline and taxane in adjuvant/metastatic setting. We pooled 1644 patients from two phase III trials and found that eribulin significantly increased survival versus control, particularly in some subgroups of interest like HER2- and triple-negative disease. Background Based on data from two multicenter, phase III clinical trials (Studies 301 and 305), eribulin (a microtubule dynamics inhibitor) is indicated in the European Union (EU) for patients with locally advanced or metastatic breast cancer (MBC) after ≥1 prior chemotherapy for advanced disease, including an anthracycline and a taxane in either the adjuvant or metastatic setting. Data from Studies 305 and 301 were pooled to investigate the efficacy of eribulin in various subgroups of patients who matched the EU label, including those with human epidermal growth factor receptor 2 (HER2)-negative and triple-negative disease. Patients and methods In Study 305 (NCT00388726), patients were randomized 2:1 to eribulin mesylate 1.4 mg/m2 (equivalent to eribulin 1.23 mg/m2 [expressed as free base]) intravenously on days 1 and 8 every 21 days] or treatment of physician's choice after 2–5 prior chemotherapies (≥2 for advanced disease), including an anthracycline and a taxane (in early/advanced setting). In Study 301 (NCT00337103), patients were randomized 1:1 to eribulin (as above) or capecitabine (1.25 g/m2 orally twice daily on days 1–14 every 21 days) following ≤3 prior chemotherapies (≤2 for advanced disease), including an anthracycline and a taxane. Efficacy end points were investigated in the intent-to-treat population and subgroups, pooled as discussed above. Results Overall, 1644 patients were included (eribulin: 946; control: 698); baseline characteristics were well matched. Overall survival was significantly longer with eribulin versus control (P < 0.01), as were progression-free survival and clinical benefit rate (both P < 0.05). Significant survival benefits with eribulin versus control were observed in a wide range of patient subgroups, including HER2-negative or triple-negative disease (all P < 0.05). Conclusion Our findings underline the survival benefit achieved by eribulin used according to EU label in the overall MBC population and in various subgroups of interest, including patients with HER2-negative and triple-negative disease.

[PMID: 26092802 PMCID: PMC4502456 DOI: 10.1016/j.fgb.2015.04.014] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2015] [Revised: 04/10/2015] [Accepted: 04/13/2015] [Indexed: 11/25/2022]
Abstract
We establish Z. tritici polarity markers ZtSec4, ZtMlc1, ZtRab11, ZtExo70 and ZtSpa2. All markers localize correctly, labeling the Spitzenkörper and sites of polar exocytosis. We provide 5 carboxin-resistance conveying vectors for integration of all markers into the sdi1 locus. We provide 5 hygromycin B-resistance conveying vectors for random integration of all markers.
Fungal hyphae are highly polarized cells that invade their substrate by tip growth. In plant pathogenic fungi, hyphal growth is essential for host invasion. This makes polarity factors and secretion regulators potential new targets for novel fungicides. Polarization requires delivery of secretory vesicles to the apical Spitzenkörper, followed by polarized exocytosis at the expanding cell tip. Here, we introduce fluorescent markers to visualize the apical Spitzenkörper and the apical site of exocytosis in hyphae of the wheat pathogen Zymoseptoria tritici. We fused green fluorescent protein to the small GTPase ZtSec4, the myosin light chain ZtMlc1 and the small GTPase ZtRab11 and co-localize the fusion proteins with the dye FM4-64 in the hyphal apex, suggesting that the markers label the hyphal Spitzenkörper in Z. tritici. In addition, we localize GFP-fusions to the exocyst protein ZtExo70, the polarisome protein ZtSpa2. Consistent with results in the ascomycete Neurospora crassa, these markers did localize near the plasma membrane at the hyphal tip and only partially co-localize with FM4-64. Thus, these fluorescent markers are useful molecular tools that allow phenotypic analysis of mutants in Z. tritici. These tools will help develop new avenues of research in our quest to control STB infection in wheat.

Abstract
We establish Z. tritici fimbrin (ZtFim1) and small GTPases (ZtRab5, ZtRab7) as endocytic markers. All markers localize correctly, proven by live cell imaging and co-staining and pharmaceutical studies. We provide 3 carboxin-resistance conveying vectors for integration of all markers into the sdi1 locus. We provide 3 hygromycin B-resistance conveying vectors for random integration of all markers.
Hyphal growth in filamentous fungi is supported by the uptake (endocytosis) and recycling of membranes and associated proteins at the growing tip. An increasing body of published evidence in various fungi demonstrates that this process is of essential importance for fungal growth and pathogenicity. Here, we introduce fluorescent markers to visualize the endocytic pathway in the wheat pathogen Zymoseptoria tritici. We fused enhanced green-fluorescent protein (eGFP) to the actin-binding protein fimbrin (ZtFim1), which is located in actin patches that are formed at the plasma membrane and are participating in endocytic uptake at the cell surface. In addition, we tagged early endosomes by eGFP-labelling a Rab5-homologue (ZtRab5) and late endosomes and vacuoles by expressing eGFP-Rab7 homologue (ZtRab7). Using fluorescent dyes and live cell imaging we confirmed the dynamic behavior and localization of these markers. This set of molecular tools enables an in-depth phenotypic analysis of Z. tritici mutant strains thereby supporting new strategies towards the goal of controlling wheat against Z. tritici.

Abstract
BACKGROUND Human Nucleic Acid Binding Protein 1 and 2 (hNABP1 and 2; also known as hSSB2 and 1, respectively) are two newly identified single-stranded (ss) DNA binding proteins (SSB). Both NABP1 and NABP2 have a conserved oligonucleotide/oligosaccharide-binding (OB)-fold domain and a divergent carboxy-terminal domain, the functional importance of which is unknown. METHODS Recombinant hNABP1/2 proteins were purified using affinity and size exclusion chromatography and their identities confirmed by mass spectrometry. Oligomerization state was checked by sucrose gradient centrifugation. Secondary structure was determined by circular dichroism spectroscopy. Nucleic acid binding ability was examined by EMSA and ITC. RESULTS Both hNABP1 and hNABP2 exist as monomers in solution; however, hNABP2 exhibits anomalous behavior. CD spectroscopy revealed that the C-terminus of hNABP2 is highly disordered. Deletion of the C-terminal tail diminishes the DNA binding ability and protein stability of hNABP2. Although both hNABP1 and hNABP2 prefer to bind ssDNA than double-stranded (ds) DNA, hNABP1 has a higher affinity for ssDNA than hNABP2. Unlike hNABP2, hNABP1 protein binds and multimerizes on ssDNA with the C-terminal tail responsible for its multimerization. Both hNABP1 and hNABP2 are able to bind single-stranded RNA, with hNABP2 having a higher affinity than hNABP1. CONCLUSIONS Biochemical evidence suggests that the C-terminal region of NABP1 and NABP2 is essential for their functionality and may lead to different roles in DNA and RNA metabolism. GENERAL SIGNIFICANCE This is the first report demonstrating the regulation and functional properties of the C-terminal domain of hNABP1/2, which might be a general characteristic of OB-fold proteins.

Abstract
Helicases are molecular motors that couple the energy of ATP hydrolysis to the unwinding of structured DNA or RNA and chromatin remodeling. The conversion of energy derived from ATP hydrolysis into unwinding and remodeling is coordinated by seven sequence motifs (I, Ia, II, III, IV, V, and VI). The Q motif, consisting of nine amino acids (GFXXPXPIQ) with an invariant glutamine (Q) residue, has been identified in some, but not all helicases. Compared to the seven well-recognized conserved helicase motifs, the role of the Q motif is less acknowledged. Mutations in the human ChlR1 (DDX11) gene are associated with a unique genetic disorder known as Warsaw Breakage Syndrome, which is characterized by cellular defects in genome maintenance. To examine the roles of the Q motif in ChlR1 helicase, we performed site directed mutagenesis of glutamine to alanine at residue 23 in the Q motif of ChlR1. ChlR1 recombinant protein was overexpressed and purified from HEK293T cells. ChlR1-Q23A mutant abolished the helicase activity of ChlR1 and displayed reduced DNA binding ability. The mutant showed impaired ATPase activity but normal ATP binding. A thermal shift assay revealed that ChlR1-Q23A has a melting point value similar to ChlR1-WT. Partial proteolysis mapping demonstrated that ChlR1-WT and Q23A have a similar globular structure, although some subtle conformational differences in these two proteins are evident. Finally, we found ChlR1 exists and functions as a monomer in solution, which is different from FANCJ, in which the Q motif is involved in protein dimerization. Taken together, our results suggest that the Q motif is involved in DNA binding but not ATP binding in ChlR1 helicase.

Abstract
The use of fluorescent proteins (FPs) in plant pathogenic fungi provides valuable insight into their intracellular dynamics, cell organization and invasion mechanisms. Compared with green-fluorescent proteins, their red-fluorescent "cousins" show generally lower fluorescent signal intensity and increased photo-bleaching. However, the combined usage of red and green fluorescent proteins allows powerful insight in co-localization studies. Efficient signal detection requires a bright red-fluorescent protein (RFP), combined with a suitable corresponding filter set. We provide a set of four vectors, suitable for yeast recombination-based cloning that carries mRFP, TagRFP, mCherry and tdTomato. These vectors confer carboxin resistance after targeted single-copy integration into the sdi1 locus of Zymoseptoria tritici. Expression of the RFPs does not affect virulence of this wheat pathogen. We tested all four RFPs in combination with four epi-fluorescence filter sets and in confocal laser scanning microscopy, both in and ex planta. Our data reveal that mCherry is the RFP of choice for investigation in Z. tritici, showing highest signal intensity in epi-fluorescence, when used with a Cy3 filter set, and laser scanning confocal microscopy. However, mCherry bleached significantly faster than mRFP, which favors this red tag in long-term observation experiments. Finally, we used dual-color imaging of eGFP and mCherry expressing wild-type strains in planta and show that pycnidia are formed by single strains. This demonstrates the strength of this method in tracking the course of Z. tritici infection in wheat.

Abstract
To better understand the phenomena of ZnFe2O4 spinel formation in electric arc furnace dust, the dust was characterized with particle size analysis, X-ray fluorescence (XRF), electron backscatter diffraction (EBSD), and electron probe micro-analysis (EPMA). Different ZnFe2O4 formation reaction extents were observed for iron oxide particles with different particle sizes. ZnO particles were present as both individual particles and aggregated on the surface of larger particles. Also, the slag particles found in the off-gas were shown not to react with the zinc vapor. After confirming the presence of a ZnFe2O4 formation reaction, the thermodynamic feasibility of in-process separation - a new electric arc furnace dust treatment technology - was reevaluated. The large air intake and the presence of iron oxide particles in the off-gas were included into the thermodynamic calculations. The formation of the stable ZnFe2O4 spinel phase was shown to be thermodynamically favorable in current electric arc furnace off-gas ducts conditions even before reaching the post combustion chamber.

Abstract
Mutations in the human ChlR1 (DDX11) gene are associated with a unique genetic disorder known as Warsaw breakage syndrome characterized by cellular defects in genome maintenance. The DNA triplex helix structures that form by Hoogsteen or reverse Hoogsteen hydrogen bonding are examples of alternate DNA structures that can be a source of genomic instability. In this study, we have examined the ability of human ChlR1 helicase to destabilize DNA triplexes. Biochemical studies demonstrated that ChlR1 efficiently melted both intermolecular and intramolecular DNA triplex substrates in an ATP-dependent manner. Compared with other substrates such as replication fork and G-quadruplex DNA, triplex DNA was a preferred substrate for ChlR1. Also, compared with FANCJ, a helicase of the same family, the triplex resolving activity of ChlR1 is unique. On the other hand, the mutant protein from a Warsaw breakage syndrome patient failed to unwind these triplexes. A previously characterized triplex DNA-specific antibody (Jel 466) bound triplex DNA structures and inhibited ChlR1 unwinding activity. Moreover, cellular assays demonstrated that there were increased triplex DNA content and double-stranded breaks in ChlR1-depleted cells, but not in FANCJ(-/-) cells, when cells were treated with a triplex stabilizing compound benzoquinoquinoxaline, suggesting that ChlR1 melting of triple-helix structures is distinctive and physiologically important to defend genome integrity. On the basis of our results, we conclude that the abundance of ChlR1 known to exist in vivo is likely to be a strong deterrent to the stability of triplexes that can potentially form in the human genome.

Abstract
OBJECTIVE The precise etiology of inflammatory bowel diseases (IBDs) is still unknown although dysregulation of apoptosis likely plays an important role in this pathogenesis. However, the significance of mucosal T-cell apoptosis in ulcerative colitis (UC) is unclear. In the present work we investigated the role of TNF-related apoptosis-inducing ligand (TRAIL), which is implicated in various human disorders. PATIENTS AND METHODS Results from a total of 393 UC patients and 1292 healthy individuals were analyzed in this study. We determined the three single nucleotide polymorphisms of TRAIL in 3' untranslated regions (UTR), and examined the plasma soluble TRAIL (sTRAIL) levels by enzyme-linked immunosorbent assay. RESULTS We found that the mutant genotypes of TRAIL (G1525A/G1588A/C1595T and G1525A and G1588A) were much lower in UC patients compared to the controls. Furthermore, mutant allele and genotype of TRAIL C1595T were more prevalent in severe UC patients than in other patients (p < 0.001; p = 0.005, respectively). The three polymorphic sites in 3'UTR were in a perfect linkage disequilibrium in our study. In contrast to controls, the GAT haplotype was increased (p < 0.001), while the AAT haplotype was decreased in UC patients (p < 0.001). Besides, the plasma levels of sTRAIL were significantly higher in UC patients than in controls (p < 0.001). CONCLUSIONS Our findings suggested that increased occurrence of the genetic mutations of TRAIL in 3'UTR and possibly decreased plasma levels of sTRAIL might lead to a lower risk of UC attack in Chinese patients.

Abstract
BACKGROUND Angiotensin-converting enzyme (ACE) gene I/D polymorphism might be linked to the risk of the allergic rhinitis (AR). OBJECTIVE In the present study, we assessed the association of ACE gene I/D polymorphisms with AR susceptibility using a meta-analysis. MATERIALS AND METHODS We carried out a retrieval of studies and included the eligible studies if they met the criteria. After the data extraction, the Stata software was used to analyse the genotype frequencies. RESULTS In total, five studies with 561 patients and 603 controls were included. However, the genotype distribution among the control of one study was not consistent with the Hardy-Weinberg equilibrium. After pooling all studies, the results indicated an association between ACE gene I/D polymorphism and AR risk in the overall analysis (II vs. others: OR=0.70, 95% CI=0.54-0.92, P=0.010; D vs. I: OR=1.29, 95% CI=1.08-1.54, P=0.005). In the further analysis of the East Asians, no association between ACE gene I/D polymorphism and AR risk was observed. CONCLUSION ACE gene I/D polymorphisms were not associated with the risk of AR in East Asians. These results need to be confirmed in the following studies.

Abstract
Affective states influence subsequent attention allocation. We evaluated emotional
negativity bias modulation by reappraisal in patients with generalized anxiety
disorder (GAD) relative to normal controls. Event-related potential (ERP) recordings
were obtained, and changes in P200 and P300 amplitudes in response to negative or
neutral words were noted after decreasing negative emotion or establishing a neutral
condition. We found that in GAD patients only, the mean P200 amplitude after negative
word presentation was much higher than after the presentation of neutral words. In
normal controls, after downregulation of negative emotion, the mean P300 amplitude in
response to negative words was much lower than after neutral words, and this was
significant in both the left and right regions. In GAD patients, the negative bias
remained prominent and was not affected by reappraisal at the early stage.
Reappraisal was observed to have a lateralized effect at the late stage.
