TL;DR: It is shown that Reelin binds directly and specifically to the ectodomains of VLDLR and ApoER2 in vitro and that blockade of V LDLR and apoE receptor 2 correlates with loss of Reelin-induced tyrosine phosphorylation of Disabled-1 in cultured primary embryonic neurons.

TL;DR: Using large scale validation data from thousands of individuals, it is demonstrated that DNAm GrimAge stands out among existing epigenetic clocks in terms of its predictive ability for time-to-death, and a novel measure of epigenetic age acceleration, AgeAccelGrim.
Abstract: It was unknown whether plasma protein levels can be estimated based on DNA methylation (DNAm) levels, and if so, how the resulting surrogates can be consolidated into a powerful predictor of lifespan. We present here, seven DNAm-based estimators of plasma proteins including those of plasminogen activator inhibitor 1 (PAI-1) and growth differentiation factor 15. The resulting predictor of lifespan, DNAm GrimAge (in units of years), is a composite biomarker based on the seven DNAm surrogates and a DNAm-based estimator of smoking pack-years. Adjusting DNAm GrimAge for chronological age generated novel measure of epigenetic age acceleration, AgeAccelGrim.Using large scale validation data from thousands of individuals, we demonstrate that DNAm GrimAge stands out among existing epigenetic clocks in terms of its predictive ability for time-to-death (Cox regression P=2.0E-75), time-to-coronary heart disease (Cox P=6.2E-24), time-to-cancer (P= 1.3E-12), its strong relationship with computed tomography data for fatty liver/excess visceral fat, and age-at-menopause (P=1.6E-12). AgeAccelGrim is strongly associated with a host of age-related conditions including comorbidity count (P=3.45E-17). Similarly, age-adjusted DNAm PAI-1 levels are associated with lifespan (P=5.4E-28), comorbidity count (P= 7.3E-56) and type 2 diabetes (P=2.0E-26). These DNAm-based biomarkers show the expected relationship with lifestyle factors including healthy diet and educational attainment.Overall, these epigenetic biomarkers are expected to find many applications including human anti-aging studies.

TL;DR: Rivaroxaban was associated with relatively low VTE recurrence but higher CRNMB compared with dalteparin, and safety was assessed by major bleeding and clinically relevant nonmajor bleeding (CRNMB).
Abstract: PurposeVenous thromboembolism (VTE) is common in patients with cancer. Long-term daily subcutaneous low molecular weight heparin has been standard treatment for such patients. The purpose of this study was to assess if an oral factor Xa inhibitor, rivaroxaban, would offer an alternative treatment for VTE in patients with cancer.Patient and MethodsIn this multicenter, randomized, open-label, pilot trial in the United Kingdom, patients with active cancer who had symptomatic pulmonary embolism (PE), incidental PE, or symptomatic lower-extremity proximal deep vein thrombosis (DVT) were recruited. Allocation was to dalteparin (200 IU/kg daily during month 1, then 150 IU/kg daily for months 2-6) or rivaroxaban (15 mg twice daily for 3 weeks, then 20 mg once daily for a total of 6 months). The primary outcome was VTE recurrence over 6 months. Safety was assessed by major bleeding and clinically relevant nonmajor bleeding (CRNMB). A sample size of 400 patients would provide estimates of VTE recurrence to within ±...

TL;DR: The analysis revealed that cells with mutant p53 sequence tended to exhibit less growth inhibition in this screen than the wild-type p53 cell lines when treated with the majority of clinically used anticancer agents: including DNA cross-linking agents, antimetabolites, and topoisomerase I and II inhibitors.
Abstract: In the present study, we report the characterization of the p53 tumor suppressor pathway in the 60 cell lines of the National Cancer Institute (NCI) anticancer drug screen, as well as correlations between the integrity of this pathway and the growth-inhibitory potency of 123 anticancer agents in this screen. Assessment of p53 status in these lines was achieved through complete p53 cDNA sequencing, measurement of basal p53 protein levels and functional assessment of ( a ) transcriptional activity of p53 cDNA from each line in a yeast assay, ( b ) γ-ray-induced G 1 phase cell cycle arrest, and ( c ) γ-ray-induced expression of CIP1/WAF1, GADD45 , and MDM2 mRNA. Our investigations revealed that p53 gene mutations were common in the NCI cell screen lines: 39 of 58 cell lines analyzed contained a mutant p53 sequence. cDNA derived from almost all of the mutant p53 cell lines failed to transcriptionally activate a reporter gene in yeast, and the majority of mutant p53 lines studied expressed elevated basal levels of the mutant p53 protein. In contrast to most of the wild-type p53 -containing lines, cells containing mutant p53 sequence were also deficient in γ-ray induction of CIP1/WAF1, GADD45 , and MDM2 mRNA and the ability to arrest in G 1 following γ-irradiation. Taken together, these assessments provided indications of the integrity of the p53 pathway in the 60 cell lines of the NCI cell screen. These individual p53 assessments were subsequently used to probe a database of growth-inhibitory potency for 123 “standard agents,” which included the majority of clinically approved anticancer drugs. These 123 agents have been tested against these lines on multiple occasions, and a proposed mechanism of drug action had previously been assigned to each agent. Our analysis revealed that cells with mutant p53 sequence tended to exhibit less growth inhibition in this screen than the wild-type p53 cell lines when treated with the majority of clinically used anticancer agents: including DNA cross-linking agents, antimetabolites, and topoisomerase I and II inhibitors. Similar correlations were uncovered when we probed this database using most of the other indices of p53 status we assessed in the lines. Interestingly, a class of agents that differed in this respect was the antimitotic agents. Growth-inhibitory activity of these agents tended, in this assay, to be independent of p53 status. Our characterization of the p53 pathway in the NCI cell screen lines should prove useful to researchers investigating fundamental aspects of p53 biology and pharmacology. This information also allows for the large-scale analysis of the more than 60,000 compounds tested against these lines for novel agents that might exploit defective p53 function as a means of preferential toxicity.
