n. Analysis of conservation of gene neighbourhoods over different evolutionary levels is important for understanding operon and gene cluster evolution, and predicting functional associations. Our tool FlaGs (Flanking Genes) takes a list of NCBI protein accessions as input, clusters neighbourhood-encoded proteins into homologous groups using sensitive sequence searching, and outputs a graphical visualization of the gene neighbourhood and its conservation, along with a phylogenetic tree annotated with flanking gene conservation. FlaGs has demonstrated utility for molecular evolutionary analysis, having uncovered a new toxin-antitoxin system in prokaryotes and bacteriophages. The web version of FlaGs (webFlaGs) can optionally include a BLASTP search against a reduced RefSeq database to generate an input accession list and analyse neighbourhood conservation within the same run. FlaGs can be downloaded from https//github.com/GCA-VH-lab/FlaGs or run online at http//. Supplementary data are available at Bioinformatics online.

To investigate the efficacy and safety of ticagrelor monotherapy in patients undergoing percutaneous coronary intervention (PCI) stratified according to the baseline white blood cell (WBC) count. This is a post-hoc analysis of the GLOBAL LEADERS trial, a multicentre, open-label, randomized all-comer trial in patients undergoing PCI, comparing the experimental strategy (23-month ticagrelor monotherapy following 1-month dual anti-platelet therapy [DAPT]) with the reference strategy (12-month aspirin monotherapy following 12-month DAPT). Patients were stratified into two WBC groups, either < or ≥median WBC count of 7.8 x 109 cells/L (lower or higher WBC group, respectively). The primary endpoint was a composite of all-cause mortality or new Q-wave myocardial infarction (MI) at 2 years.Out of 14,576 patients included in the present study, 7,212 patients (49.5%) were classified as the lower WBC group, who had a significantly lower risk of both ischemic and bleeding outcomes at 2 years. At 2 years, the experimental strategy was associated with a significant lower incidence of the primary endpoint compared with the reference strategy in the lower WBC group (2.8% vs. 4.2%; hazard ratio [HR] 0.67; 95% CI 0.52-0.86) but not in the higher WBC group (4.8% vs. 4.7%; HR 1.01; 95% CI 0.82-1.25; pinteraction=0.013). There were no significant differences in the risks of BARC type 3 or 5 bleeding between two antiplatelet strategies regardless of the WBC groups. Increased WBC counts, which may reflect degree of inflammation, at the time of index procedure may attenuate the anti-ischemic benefits of ticagrelor monotherapy observed in patients with lower WBC counts.

However, little is known regarding the molecular basis and evolution of multispecificity in these enzymes. Here, we used a combined bioinformatics and experimental approaches to investigate the evolution of multispecificity in the sirtuin-1 (SIRT1) deacetylase. Guided by bioinformatics analysis of SIRT1 orthologs and substrates, we identified and examined important amino acid substitutions that have occurred during the evolution of sirtuins in Metazoa and Fungi. this website We found that mutation of human SIRT1 at these positions, based on sirtuin orthologs from Fungi, could alter its substrate specificity. These substitutions lead to reduced activity toward K382 acetylated p53 protein, which is only present in Metazoa, without affecting the high activity toward the conserved histone substrates. Results
