1High-throughput screening of mouse gene knockouts identifies established and novel skeletal phenotypes显示文摘Screening gene function in vivo is a powerful approach to discover novel drug targets. We present high-throughput screening(HTS) data for 3 762 distinct global gene knockout(KO) mouse lines with viable adult homozygous mice generated using either gene-trap or homologous recombination technologies. Bone mass was determined from DEXA scans of male and female mice at 14 weeks of age and by microCT analyses of bones from male mice at 16 weeks of age. Wild-type(WT) cagemates/littermates were examined for each gene KO. Lethality was observed in an additional 850 KO lines. Since primary HTS are susceptible to false positive findings, additional cohorts of mice from KO lines with intriguing HTS bone data were examined. Aging,ovariectomy, histomorphometry and bone strength studies were performed and possible non-skeletal phenotypes were explored. Together, these screens identified multiple genes affecting bone mass: 23 previously reported genes(Calcr, Cebpb, Crtap, Dcstamp, Dkk1, Duoxa2, Enpp1, Fgf23, Kiss1/Kiss1 r, Kl(Klotho),Lrp5, Mstn, Neo1, Npr2, Ostm1, Postn, Sfrp4, Slc30a5, Slc39a13, Sost, Sumf1, Src, Wnt10b), five novel genes extensively characterized(Cldn18, Fam20 c, Lrrk1, Sgpl1, Wnt16), five novel genes with preliminary characterization(Agpat2, Rassf5, Slc10a7, Slc26a7, Slc30a10) and three novel undisclosed genes coding for potential osteoporosis drug targets.Robert Brommage Jeff Liu Gwenn M Hansen Laura L Kirkpatrick David G Potter Arthur T Ss Brian Zambrowicz David R Powell Peter Vogel 2014Bone Research2014,2,3:7

4High-density SNP-based genetic maps for the parents of an outcrossed and a selfed tetraploid garden rose cross, inferred from admixed progeny using the 68k rose SNP array显示文摘Dense genetic maps create a base for QTL analysis of important traits and future implementation of marker-assisted breeding.In tetraploid rose,the existing linkage maps include<300 markers to cover 28 linkage groups(4 homologous sets of 7 chromosomes).Here we used the 68k WagRhSNP Axiom single-nucleotide polymorphism(SNP)array for rose,in combination with SNP dosage calling at the tetraploid level,to genotype offspring from the garden rose cultivar‘Red New Dawn’.The offspring proved to be not from a single bi-parental cross.In rose breeding,crosses with unintended parents occur regularly.We developed a strategy to separate progeny into putative populations,even while one of the parents was unknown,using principle component analysis on pairwise genetic distances based on sets of selected SNP markers that were homozygous,and therefore uninformative for one parent.One of the inferred populations was consistent with self-fertilization of‘Red New Dawn’.Subsequently,linkage maps were generated for a bi-parental and a self-pollinated population with‘Red New Dawn’as the common maternal parent.The densest map,for the selfed parent,had 1929 SNP markers on 25 linkage groups,covering 1765.5 cM at an average marker distance of 0.9 cM.Synteny with the strawberry(Fragaria vesca)genome was extensive.Rose ICM1 corresponded to F.vesca pseudochromosome 7(Fv7),ICM4 to Fv4,ICM5 to Fv3,ICM6 to Fv2 and ICM7 to Fv5.Rose ICM2 corresponded to parts of F.vesca pseudochromosomes 1 and 6,whereas ICM3 is syntenic to the remainder of Fv6.Mirjana Vukosavljev Paul Arens Roeland E Voorrips Wendy P C van't Westende G D Esselink Peter M Bourke Peter Cox W Eric van de Weg Richard G F Visser Chris Maliepaard Marinus J M Smulders 2016Horticulture Research2016,3,1:6
5Model combining pre-transplant tumor biomarkers and tumor size shows more utility in predicting hepatocellular carcinoma recurrence and survival than the BALAD models显示文摘AIM To assess the performance of BALAD, BALAD-2 and their component biomarkers in predicting outcome of hepatocellular carcinoma(HCC) patients after liver transplant.METHODS BALAD score and BALAD-2 class are derived from bilirubin, albumin, alpha-fetoprotein(AFP), Lens culinaris agglutinin-reactive AFP(AFP-L3), and des-gammacarboxyprothrombin(DCP). Pre-transplant AFP, AFP-L3 and DCP were measured in 113 patients transplanted for HCC from 2000 to 2008. Hazard ratios(HR) for recurrence and death were calculated. Univariate and multivariate regression analyses were conducted. C-statistics were used to compare biomarker-based to predictive models. RESULTS During a median follow-up of 12.2 years, 38 patients recurred and 87 died. The HRs for recurrence in patients with elevated AFP, AFP-L3, and DCP defined by BALAD cut-off values were 2.42(1.18-5.00), 1.86(0.98-3.52), and 2.83(1.42-5.61), respectively. For BALAD, the HRs for recurrence and death per unit increased score were 1.48(1.15-1.91) and 1.59(1.28-1.97). For BALAD-2, the HRs for recurrence and death per unit increased class were 1.45(1.06-1.98) and 1.38(1.09-1.76). For recurrence prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs. 0.64, 0.61, 0.53, and 0.53 for BALAD, BALAD-2, Milan, and UCSF, respectively. Similarly, for death prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs 0.65,0.61, 0.52, and 0.50 for BALAD, BALAD-2, Milan, and UCSF. A new model combining biomarkers with tumor size at the time of transplant(S-LAD) demonstrated the highest predictive capability with c-statistics of 0.71 and 0.69 for recurrence and death. CONCLUSION BALAD and BALAD-2 are valid in transplant HCC patients, but less predictive than the three biomarkers in combination or the three biomarkers in combination with maximal tumor diameter(S-LAD).Nicha Wongjarupong Gabriela M Negron-Ocasio Roongruedee Chaiteerakij Benyam D Addissie Essa A Mohamed Kristin C Mara William S Harmsen J Paul Theobald Brian E Peters Joseph G Balsanek Melissa M Ward Nasra H Giama Sudhakar K Venkatesh Denise M Harnois Michael R Charlton Hiroyuki Yamada Alicia Algeciras-Schimnich Melissa R Snyder Terry M Therneau Lewis R Roberts 2018World Journal of Gastroenterology2018,24,12:5
6In Situ Etching for Total Control Over Axial and Radial Nanowire Growth显示文摘We report a method using in situ etching to decouple the axial from the radial nanowire growth pathway,independent of other growth parameters.Thereby a wide range of growth parameters can be explored to improve the nanowire properties without concern of tapering or excess structural defects formed during radial growth.We demonstrate the method using etching by HCl during InP nanowire growth.The improved crystal quality of etched nanowires is indicated by strongly enhanced photoluminescence as compared to reference nanowires obtained without etching.Magnus T.Borgström Jesper Wallentin Johanna Trägårdh Peter Ramvall Martin Ek LReine Wallenberg Lars Samuelson Knut Deppert 2010Nano Research2010,3,4:4

8Diagnostic accuracy of tests for Helicobacter pylori in an Alaska Native population显示文摘AIM:To evaluate the accuracy of two non-invasivetests in a population of Alaska Native persons. Highrates of Helico bacter pylori(H. pylori) infection,H. pylori treatment failure,and gastric cancer in this population necessitate documentation of infection status atmultiple time points over a patient's life.METHODS:In 280 patients undergoing endoscopy,H. pylori was diagnosed by culture,histology,rapidurease test,13C urea breath test(UBT) ,and immuno-globulin G antibodies to H. pylori in serum. The performances of 13C-UBT and antibody test were compared to a gold standard defined by a positive H. pylori testby culture or,in case of a negative culture result,bypositive histology and a positive rapid urease test.RESULTS:The sensitivity and specificity of the 13C-UBT were 93% and 88%,respectively,relative to thegold standard. The antibody test had an equivalents ensitivity of 93% with a reduced specificity of 68%.The false positive results for the antibody test were as-sociated with previous treatment for an H. pylori infection [relative risk(RR) = 2.8]. High levels of antibodiesto H. pylori were associated with chronic gastritis and male gender,while high scores in the 13C-UBT testwere associated with older age and with the H. pyloribacteria load on histological examination(RR = 4.4) .CONCLUSION:The 13C-UBT out performed the anti-body test for H. pylori and could be used when a non-invasive test is clinically necessary to document treatment out come or when monitoring for reinfection.Dana L Bruden Michael G Bruce Karen M Miernyk Julie Morris Debby Hurlburt Thomas W Hennessy Helen Peters Frank Sacco Alan J Parkinson Brian J McMahon 2011World Journal of Gastroenterology2011,17,42:3

11重组脊髓灰质炎病毒用于治疗复发胶质母细胞瘤(英文)显示文摘Background The prognosis of patients with recurrent World Health Organization(WHO)grade IV malignant glioma is dismal,and there is currently no effective therapy.We conducted a dose-finding and toxicity study in this population of patients,evaluating convection-enhanced,intratumoral delivery of the recombinant nonpathogenic polio-rhinovirus chimera(PVSRIPO).PVSRIPO recognizes the poliovirus receptor CD155,which is widely expressed in neoplastic cells of solid tumors and in major components of the tumor microenvironment.Methods We enrolled consecutive adult patients who had recurrent supratentorial WHO grade IV malignant glioma,confirmed on histopathological testing,with measurable disease(contrast-enhancing tumor of≥1 cm and≤5.5 cm in the greatest dimension).The study evaluated seven doses,ranging between 107 and 1010 50%tissue-culture infectious doses(TCID50),first in a dose-escalation phase and then in a dose-expansion phase.Results From May 2012 through May 2017,a total of 61 patients were enrolled and received a dose of PVSRIPO.Dose level-1(5.0×107TCID50)was identified as the phase 2 dose.One dose-limiting toxic effect was observed;a patient in whom dose level 5(1010TCID50)was administered had a grade 4 intracranial hemorrhage immediately after the catheter was removed.To mitigate locoregional inflammation of the infused tumor with prolonged glucocorticoid use,dose level 5 was deescalated to reach the phase 2 dose.In the dose-expansion phase,19%of the patients had a PVSRIPO-related adverse event of grade 3 or higher.Overall survival among the patients who received PVSRIPO reached a plateau of 21%(95%confidence interval,11 to 33)at 24 months that was sustained at 36 months.Conclusions Intratumoral infusion of PVSRIPO in patients with recurrent WHO grade IV malignant glioma confirmed the absence of neurovirulent potential.The survival rate among patients who receivedPVSRIPO immunotherapy was higher at 24 and 36 months than the rate among historical controls.Desjardins A Gromeier M Herndon JE 2nd Beaubier N Bolognesi DP Friedman AH Friedman HS McSherry F Muscat AM Nair S Peters KB Randazzo D Sampson JH Vlahovic G Harrison WT McLendon RE Ashley D Bigner DD 2018中华神经外科疾病研究杂志2018,17,4:2
