No relationship was observed between bFGF levels and maximum apoptotic index (data not shown).Effects of tumor pathobiological parameters on the relationship between bFGF level and paclitaxel sensitivity The tumor pathobiological data of patient tumors were obtained from our previous report [20]. Analysis of the relationship between bFGF level and tumor sensitivity to the antiproliferation effect in tumor subgroups revealed significantly better correlations (i.e., higher r2 values) in stage III-IV, p53-positive and aFGF-negative tumors, and tumors with higher-than-median bFGF level (Figures 3 and 4), compared to low stage (I-II), p53-negative, aFGFpositive, and low bFGF tumors. The median bFGF level was 9.8 pg/mg protein. No differences were observed for the other pathobiological parameters (i.e., high or low grade, high or low levels of p-glycoprotein or Bcl-2).findings using the conventional, visual scoring method. However, while both methods yielded the same finding of an inverse correlation between bFGF level and tumor sensitivity PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/28878015 to the antiproliferation effect of paclitaxel, the image analysis method provided more robust data and presented several additional advantages, as follows. The visual scoring method was semi-quantitative and based on the differential staining intensity at three different antibody concentrations. For example, a tumor AviptadilMedChemExpress Aviptadil showing no staining at the highest antibody concentration was scored as negative, a tumor showing positive staining at different antibody concentrations were scored as one, two or three pluses. In comparison, the current method required using a single antibody dilution, and, because the quantitative image analysis results were based on the results obtained from simultaneously stained standard curve samples, was not subjected to or affected by interday variability in staining intensity. Furthermore, the image analysis method applied the same analysis parameters to all samples and therefore minimized the potential operator bias. The image analysis method, by measuring bFGF levels in individual tumors, provided values for each of the 87 tumors. In comparison, the visual examination results provided readings of relative intensity which provided only 4 scores (negative and three scores of positive staining). This, in turn, enabled the analysis of the relationship between bFGF level and tumor sensitivity to the antiproliferation effect of paclitaxel in subgroups of tumors with different pathobiological properties; the results show better correlations in four pathobiological subgroups (late stages,.

Can be expressed as a product of mutation operators on an initial (extended) AZD-8055 manufacturer sequence state. For example, the indel history illustrated in panels a and b of Fig. 4 can be represented as a series ??^ ^ ^ ^ of indel events, M D ?; 3? M I ?; 2? M D ?; 3? M I ?; 1?, on the initial basic state sI (given above). Then, the final result of this indel history is expressed as: ^ ^ ^ ^ hsI jM D ?; 3 I ?; 2 D ?; 3 I ?; 1?. Figure 4c shows the MSA among the initial, intermediate and final sequence states. Figure 4d shows the resulting PWA between the initial and final sequence states. These new tools, the ancestry indices and the operator representation of mutations, will play essential roles in our theoretical development described below. In the SID models [21], each evolutionary process was expressed as a (time-recorded) trajectory of sequence states, each of which was represented by an array of residues (without ancestry assignments). In consequence, an instantaneous transition from a state to the next state was often expressed as a summation of multiple possible muta tions. (For example, the transition from ? ; A to 0 ^ ^ ? could result from either M D ?; 1?or M D ?; 2?). Ancestry indices help avoid such ambiguous channels byEzawa BMC Bioinformatics (2016) 17:Page 8 of^ Fig. 3 Operator representation of mutations. a A substitution operator, M S ?; T C ? The residues before and after the substitution are in boldface in blue ^ ^ and red, respectively. b An insertion operator, M I ?; 3? and a fill-in operator, F ?; ; A; C ? The inserted sites are shaded in cyan. (Note that “A” at the top ^ of the rightmost inserted column means the ancestry index of 10, not the residue state of A). c A deletion operator, M D ?; 4? The sites to be deleted are shaded in magenta. In this figure, the extended sequence states were used for illustration. The bra-vector below each array denotes the state. The extended state, s, is identical to that in Fig. 2b. Each vertical arrow indicates the action of the mutation operator beside it. Note that the first arguments of all operators and the second argument of the deletion operator specify positions along the sequence, and not ancestries (specified at the top of the sites)uniquely defining each instantaneous state-to-state transition as an action of a single mutation. (In the above ex ample, the former causes the transition from ??; 2 to ?? ??, and the latter yields the transition fromto ?? ??). This, in conjunction with the operator representation of mutations, enables us to shift the focus from the trajectory of sequence states to the history of mutations, especially indels. This shift of focus, as wellFig. 4 Example indel history and resulting alignments. a An example indel history in terms of the bra-vectors of sequence states and indel operators. b The graphical illustration of the history using basic sequence states.

Thus far only a few genes involved in metabolic and virulence functions have been identified and characterized in H. somni using traditional methods. Analyses of the genome sequences of several Pasteurellaceae species have provided insights into their biology and evolution. In view of the economic and ecological importance of H. somni, the genome sequence of pneumonia strain 2336 has been determined and compared to that of commensal strain 129Pt and other members of the Pasteurellaceae. Results: The chromosome of strain 2336 (2,263,857 bp) contained 1,980 protein coding genes, whereas the chromosome of strain 129Pt (2,007,700 bp) contained only 1,792 protein coding genes. Although the chromosomes of the two strains differ in size, their average GC content, gene density (total number of genes predicted on the chromosome), and percentage of sequence (number of genes) that encodes proteins were similar. The chromosomes of these strains also contained a number of discrete prophage regions and genomic islands. One of the genomic islands in strain 2336 contained genes putatively involved in copper, zinc, and tetracycline resistance. Using the genome sequence data and comparative analyses with other members of the Pasteurellaceae, several H. somni genes that may encode proteins involved in virulence (e.g., filamentous haemaggutinins, adhesins, and polysaccharide biosynthesis/modification enzymes) were identified. The two strains contained a total of 17 ORFs that encode putative glycosyltransferases and some of these ORFs had characteristic simple sequence repeats within them. Most of the genes/loci common to both the strains were located in different regions of the two chromosomes and occurred in opposite orientations, indicating genome rearrangement since their divergence from a.

All tophi with CR. Results: Among 212 patients randomized in the RCTs
All tophi with CR. Results: Among 212 patients randomized in the RCTs, 155 (73 ) had 1 tophus and 547 visible tophi were recorded at baseline. Overall tophus CR was recorded in 45 of patients in the biweekly group (P = 0.002 versus placebo), 26 in the monthly group, and 8 in the placebo group after six months of RCT therapy. TT-CR rates at six months were 28 , 19 , and 2 of tophi, respectively. Patients meeting the primary endpoint of sustained urate-lowering response to therapy (responders) were more likely than nonresponders to have an overall tophus CR at six months (54 vs 20 , respectively and 8 with placebo). Both overall tophus CR and TT-CRs increased with treatment duration in the OLE, reaching 70 (39/56) of patients and 55 (132/238) of target tophi after one year of treatment in patients receiving pegloticase during both the RCTs and OLE. At that time point, more tophi had resolved in responders (102/145 or 70 of tophi) than nonresponders (30/93; 32 ). Conclusions: Pegloticase reduced tophus burden in patients with refractory tophaceous gout, especially those achieving sustained urate-lowering. Complete resolution of tophi occurred in some patients by 13 weeks and in others with longer-term therapy.

Arthritis Research Therapy 2013, 15:R137 http://arthritis-research.com/content/15/5/RPage 2 ofIntroduction Refractory gout refers to the condition of a population of patients with symptomatic gout in whom treatment has failed to maintain a serum uric acid (SUA) level less than 6 mg/dl with oral urate-lowering therapies (ULTs) and appropriate medical management [1,2]. Patients with refractory gout are at risk for progressive urate crystal deposition disease, characterized by frequent attacks of acute gouty arthritis, gouty arthropathy and enlarging tophi, which are often associated with chronic pain, impairment of physical function and compromised healthrelated quality of life [1,3,4]. The tophus, a cardinal feature of chronic gout, is a mass of urate crystals embedded in fibrous and inflammatory tissue. Tophi contribute to gouty joint destruction and deformity and may undergo acute or chronic ulceration, erode adjacent bone, cause pressure effects on surrounding tissues and organs, interfere with joint function or become infected [1,5-9]. Once established, tophi do not regress or resolve unless the extracellular urate saturation that supports urate crystal deposition (reflected by hyperuricemia or SUA in excess of 6.8 mg/dl) is reversed and subsaturating urate levels are maintained. Achievement and maintenance of SUA in a range less than 6.0 mg for months to years does, however, promote dissolution PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/25962748 of urate crystal deposits and prevent further crystal deposition in tissues [10]. Rates of resolution of tophaceous deposits appear to be dependent on the extent of urate-lowering [11,12]. Furthermore, tracking the course of tophus size or number over time during treatm.

Ssociated with these operons. As a result we identified two uncharacterized superfamilies that tended to strongly co-occur with the mutagenic SOS operons across most major lineages of the bacterial tree (Figure 1 and Additional file 1; 25 and 65 of all their recovered gene neighborhood showed such associations). The first of these is typified by the Bacillus subtilis YoqW protein (gi: 384175670) and the E.coli protein YedK (gi: 49176171), and contains a globular domain of about 220-260 residues in length, which was previously described as containing a domain of unknown (DUF159) in the Pfam database [16]. The second of these codes for a protein prototyped by Geobacter sulfurreducens GSU0042 (gi: 39995153) and contains a previously unknown, small, globular domain approximately 80 residues in length. Iterative sequence profile searches with PSI-BLAST and hidden Markov model searches with HMMSEARCH using an alignment of different representatives of this domain showed that it was related to a conserved domain found in the ImuB family of proteins that occurs C-terminal to the family Y DNA polymerase domain. For instance, HMMSEARCH using a HMM derived from the small GSU0042-like proteins recovered the ImuB C-terminal domains with e-value 10-4-10-5. Likewise, a search initiated using the Syntrophomonas wolfei protein Swol_1669 (gi: 114567184) recovered the ImuB C-terminal domains in a PSI-BLAST search (e-value = 10-3-10-4; iteration 7). Accordingly, we named this conserved domain the ImuB-C (for ImuB C-terminal) domain.Aravind et al.

Operons are labeled with the gi number of the SRAP or ImuB-C gene in the neighborhood followed by the species name. Standard names of encoded domains are used to label genes, the rest being MPep, metallopeptidase; ATPDL, ATP-dependent DNA ligase. In the network graph, genes are represented as nodes, and edges indicate the gene context with the arrow head pointing to the gene in the 3′ direction of the neighborhood.

IHC analysis for Akt activity was performed on the tumors harvested at the end of the treatment of an LNCaP xenograft mouse model. Paraffin embedded sections were immuno-stained for expression of phosphorylated Akt (Ser473). Tumors from mice treated with the MP470-Erlotinib combination had a near complete Aprotinin web inhibition of Akt phosphorylation compared to control or individual therapies (200 ?.may contribute to the tumor suppression seen in an LNCaP xenograft mouse model. In addition, hormonerefractory prostate cancer is a major clinical obstacle as there are no drugs to halt its progression [3]. Previous studies have shown that PI3K/Akt activation is associated with prostate cancer progression from an androgendependent to an androgen-independent state [30]. In androgen-ablated LNCaP cells, PI3K/Akt activity is elevated and required for growth and survival [31] and inhibition can restore sensitivity to apoptosis induction [32]. In a mouse xenograft model of LNCaP, conditional Akt activation promotes tumor growth in castrated animals by enhanced cell proliferation and inhibition of apoptosis [28]. Thus, blockage of Akt activity should prove beneficial for hormone-refractory prostate cancer. Our experiments showed that the MP470-Erlotinib combination efficiently inhibited Akt activity in androgen-ablated LNCaP cells (Fig. 3B), suggesting that this combination may be a viable treatment modality in patients failing androgen blockade or can be administered with androgens in front-line therapy to prevent hormone refractory status. Except for the loss of PTEN function, PI3K/Akt signaling is often dysregulated in human cancer due to constitutive activation of receptor tyrosine kinases (RTKs) [41]. Of the known RTKs, activation of the HER family (HER1, 2 and 3) and the PDGFR family has been demonstrated to associate with prostate cancer progression [16,19]. In prostate cancer cell lines, HER family receptors are over-expressed [42,43] and inhibition with specific TKIs has shown antitumor effects in vitro and in vivo [44,45]. HER familymembers are also widely expressed in cancerous tissues of the prostate and significant over-expression is found in hormone-refractory prostate cancer and metastatic tissue compared to localized prostate cancer [46]. Hence, HER family receptors have become potential therapeutic targets in prostate cancer [47]. MP470, designed as an ATPcompetitive TKI was very effective in inhibiting tyrosine phosphorylation in LNCaP and NIH3T3 cells after pervanadate stimulation (Fig. 4A and 4B). Further, the MP470-Erlotinib combination completely inhibited tyrosine phosphorylation and p85 binding (Fig. 4C) as well as Akt activity. The RTK phospho-antibody assay identified the HER family (HER1, HER2 and HER3) in LNCaP cells as targeted by MP470 (Fig. 5A). Erlotinib or MP470 alone did not totally inhibit phosphorylation of the HER family. However, MP470-Erlotinib combination completely inhibited the phosphorylation of HER1, PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/26104484 HER2 and HER3, the binding of PI3K regulatory subunit p85 to HER3 and d.

Lationships between them are identified (see Figure 2). Biological NEs correspond to classes such as genes, proteins, cell lines, species, compounds, phenotypes, diseases, etc. Named entity recognition (NER) refers to the problem of labelling both the location (start, end) and the semantic class/type PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/26866270 of a NE in text, and normalisation refers to the process of mapping a NEFigure 2. An example of a text-mining pipeline. Given a sentence from a paper (A), named entities (NEs) are extracted (green for species entities, red for protein/gene entities, blue for relationship cues) (B); these entities are then normalised to a corresponding identifier scheme (C); and relationships between entities extracted (D). The final result in this case is a network which explicitly encodes the semantic relationships between NEs found in the sentence. Text taken from PMID:14613582.# HENRY STEWART PUBLICATIONS 1479 ?364. HUMAN GENOMICS. VOL 5. NO 1. 17 ?29 OCTOBERREVIEWHarmston, Filsell and Stumpfto a unique identifier (or set of identifiers). Following NER and normalisation it is useful to determine if a real relationship exists between two or more NEs, as well as the type of relationship. Simply identifying that NEs occur together in a contiguous block of text does hint at the existence of some form of relationship; however, this relationship may be completely speculative, or the text may state that a relationship between the NEs does not exist.14 In biological research papers, two entities can co-occur for many reasons, including functional, physical, syntenic and evolutionary relationships. The performance of TM systems is often evaluated using precision and recall metrics against manually curated gold standard corpora. Precision can be interpreted as the probability that a randomly selected result is a true positive and is calculated as the number of true positives obtained over the sum of true positives and false positives. Recall can be intuitively interpreted as the probability that a randomly selected positive result is correctly identified; it can be calculated as the number of true positives divided by the number of items that should be found (the sum of true positives and false negatives).NERBiology is a dynamic and ever-expanding research area. This means that there are millions of entity names in use, with new ones constantly being created (eg through genome annotation and drug development). Neologisms are prevalent in the literature; it has been jokingly commented: `Scientists would rather share each other’s underwear than use each other’s nomenclature’ (Keith Yamamoto). Biological NER thus tends to be more difficult than NER tasks in other domains (eg newswires) due to the variability of biological nomenclatures.15,16 A single gene can have many synonyms (eg P53, TP53 and TRP53 all refer to the same gene). Gene names are subject to morphological (eg transcription factor, transcriptional factor), orthographic (eg nuclear factor [NF] kappa B, NF kB), combinatorial (eg homologue of actin, actin homologue) and Ornipressin site inflectional variation (eg antibody, antibodies). The HUGO Gene Nomenclature committee (HGNC)was created with the aim of assigning a unique gene symbol to every gene; however, currently, not all genes have been assigned a name and there are still problems with gene names mentioned in the past literature. Gene names can overlap with other names relating to different entity types in the biological domain, as well as with words that are found i.
