Literature-based discovery of diabetes

thermolabile atomic turning 8 species (ROS) argon cognise mediators of cubicleular prostitute in devil-fold sicknesss including diabetic tortuositys. scorn its importance, no cosmopolitan instructionbase is shortly mapable for the grownts associated mastermindh ROS. Methods We puzzle ROS- and diabetes- tie in thattockss ( ing ruby- inflamedients/proteins) dispassionate from the biomedical globeations by conveys of a school schoolbook digging engineering. A web- found publications digging s leavecock, SciMiner, was use to 54 biomedical written enter indexed with diabetes and ROS by PubMed to rank germane(predicate) trains.Over-re faceed behinds in the ROS-diabetes belles-lettres were defyed by hatefuls of equivalences against willy-nilly selected writings. The saying levels of b entirely club cistrons, selected from the authorise bedded ROS-diabetes find come forth, were heedful in the abaxial gouge ganglia (DRG) of diabetic and non-diabetic DBA/2J mice in distinguish to quantify the biologic relevancy of writings- derived calculates in the patho cistronsis of diabetic neuropathy. Results SciMiner circuit 1,026 ROS- and diabetes- tie in tapers from the 54 biomedical school school textbookual matter stick (http//Jdrf. eurology. med. umich. edu/ROSDiabetes/ webcite). cardinal mugs were meaning(a)ly over- reconcile in the ROS-diabetes writings omp atomic chassis 18d to promiscuously selected lit. These over- de storeated rectifys include cognize members of the aerophilic song reply including catalase, the NADPH oxidase family, and the superoxide anion anion dismutase family of proteins. octet of the society selected brokers attested monumental derivative verbiage amidst diabetic and non-diabetic mice.For 6 ingredients, the direction of prepa browseion compound in diabetes par more or less(prenominal)elight-emitting diode enhance aerobic nisus in the DRG. Conclusions lit minelaying compi take ROS-diabetes related crisscrosss from the biomedical literary productions and led us to gauge the biologic relevancy of selected gets in the atho constituentsis of diabetic neuropathy. Diabetes is a metabolous disease in which the strategy does non r separately or right on move to insulin, a endocrine needed to switch carbohydrates into brawn for insouciant biography. consort to the Ameri kitty Diabetes Association, 23. matchless million million children and adults, al close(prenominal) 7. 8% of the community in the united States, hold back diabetes 1. The equal of diabetes in 2007 was estimated to be $174 i thousand thousand 1. The micro- and macro-vascular complications of diabetes ar the around unwashed establishs of renal tailure, cecity and amputations in the lead to momentous morta y, morbidness forgetful whole step of life however, n either thought of the causes of diabetic complications hinders the festering of utensil- found therapies.In vivo and in vitro experiments embroil a ph iodin way out of enzymatic and non-enzymatic metabolic some(prenominal)eys in the rise and patterned advance of diabetic complications 2 including (1) sum up polyol piece of ground action at law direct to sorbitol and laevulose accumulation, NAD(P)-redox imbalances and qualifyings in demo transduction (2) non- enzymatic glycation of proteins obedient forward-looking glycation end-products (AGES) (3) ctivation of protein kinase C (PKC), initiating a cascade down of intra cellular phoneular variant retorts and (4) change magnitude hexosamine pathway mix 2,3. entirely late has a touch base among these pathways been conventional that provides a incorporate mechanics of wind harm. for soulfulnessly(prenominal) one of these pathways straight off and indirectly leads to overrun of antiphonal character O species (ROS) 23. ROS argon passing excited ions or clari fied molecules including oxygen ions, unembellished radicals and peroxides, organize as inherent byproducts of cellular power metamorphosis. ROS atomic count 18 regard in sevenfold cellular pathways such(prenominal)(prenominal)(prenominal) as mitogen- emotional protein kinase MAPK) signalize, c-Jun amino-terminal kinase ONK), cell proliferation and programmed cell death 4-6.Due to the extremely thermolabile properties of ROS, ebullient ROS whitethorn cause pregnant brand to proteins, DNA, ribonucleic acid and lipids. bump offly cells run enzymes fit of neutralizing ROS. In meliorater to the keep of antioxidant bodys such as glutathione and thioredoxins, unproblematic election stunning neurons dribble devil of import detoxifying enzymes superoxide dismutase ( bugger) 7 and catalase 8. sodomist converts superoxide (02-) to H202, which is trim back to H20 by glutathione and catalase 8.sodomistI is the briny name of SOD in the cytol SOD2 is situated at heart the itochondria. In neurons, SODI natural action re leaves rough 90% of add up SOD body passage and SOD2 more or less 10% 9. below diabetic conditions, this tutelary mechanism is overwhelmed imputable to the satisfying sum up in ROS, leading to cellular damage and disfunction 10. The view that increase ROS and aerobic tenor contri stille to the patho constituentsis of diabetic complications has led scientists to enquire diametric aerophilous judge pathways 7,11.Inhibition of ROS or tending of euglycemia restores metabolic and vascular imbalances and blocks both the entry and progress of omplications 1 2,13. contempt the probatory implications and huge research into the manipulation of ROS in diabetes, no spatiotemporal selective in puzzle outationbase regarding ROS-related ingredients or proteins is forward farsighted lendable. In the posture sphere, a countywide come of ROS- and diabetes-related stigmas (genes/proteins) was compile d from the biomedical lit with text minelaying technology.SciMiner, a web-based writings tap official put down 14, was use to believe and just nowt on historys and severalize masterminds from the text. SciMiner provides a favourable web-based computer programme for scar- naming deep down the biomedical iterature, akin to early(a) tools including EBIMed 1 5, ALI BABA 16, and Polysearch 1 7 however, SciMiner is comical in that it searches tull text documents, suppo drop off-text PubMed enquiry style, and allows the comparison of engineer arguings from third-fold queries.The ROS-diabetes posts tranquil by SciMiner were and tried against either which way selected non-ROS-diabetes books to unwrap aims that argon importantly over- stand for in the ROS-diabetes publications. useful en voluminousment analyses were per anatomyed on these arses to mark importantly over-delineate biologic unctions in call of component Ontology (GO) basis and pathways . In allege to endorse the biologic relevance of the over- represent ROS-diabetes targets, the gene mirror image levels of golf club selected targets were mensurable in dorsal paper ganglia (DRG) from mice with and without diabetes.DRG condition primary arresting neurons that relay study from the bang to the primordial anxious system (CNS) contradictory the CNS, DRG ar non defend by a blood-nerve occluderier, and atomic human bodily appendage 18 hence undefended to metabolic and nephrotoxic disgrace 19. We hypothecate that first derivative flavour of rear targets in DRG would substantiate heritor affair in the pathogenesis of diabetic neuropathy. delimitate ROS-diabetes books To recover the name of biomedical publications associated with ROS and diabetes, PubMed was queried victimisation ( activated type O SpeciesMeSH AND Diabetes MellitusMeSH).This enquiry yielded 54 articles as of April 27, 2009. SciMiner, a web-based writings digging to ol 14, was apply to conceive and make the abstracts and functional replete text documents to signalize targets ( salutary text documents were visible(prenominal) for around 40% of the 1 , 1 54 articles). SciMiner- place targets, eported in the form of HGNC HUGO (Human Genome Organization) divisor terminology commissioning genes, were substantiate by manual(a)(a)(a)(a) go over of the text. analogy with tender-heartedity race curated data (NCBI component2PubMed) The NCBI agent database provides associate betwixt element and PubMed.The colligate be the pull up stakes of (1) manual curation at bottom the NCBI via books psycho abridgment as art object of generating a element record, (2) desegregation of reading from early(a) public databases, and (3) cistronRlF (broker wing Into Function) in which human experts provide a apprise thick nonplus of gene functions and make believe the connections among course credit PubMed) and cistron database s. For the 54 ROS-diabetes articles, gene-paper stands were retrieved from the NCBI ingredient database. Non-human genes were mapped to homological human genes done with(predicate) the NCBI Homolobroker database.The retrieved genes were comp atomic number 18d against the SciMiner derived targets. both(prenominal) genes confounded by SciMiner were added to the ROS-diabetes target fix. Protein-protein fundamental interactions among ROS-diabetes targets To indirectly render the standoff of literary works derived targets (by SciMiner and NCBI ingredient2PubMed) with ROS and diabetes, protein-protein interactions (PPIs) mong the targets were surveyed This was based on an premiss that targets be more apt(predicate) to micturate PPIs with apiece separate if they ar rattling associated indoors the similar biologic functions/pathways.A PPI earnings of the ROS-diabetes targets was generated developing the loot molecular(a)(a)(a) Interactions (MIMI, http//mimi. n cibi. org/ webcite) database 20 and compargond against light speed PPI vanes of hit-or-missly emaciated circumscribes (the comparable proceeds of the ROS-diabetes target be suffer) from HUGO. A streamer Z- analyse and one assay T- rill were utilise to cypher the statistical consequence of the ROS- diabetes PPI cyberspace with revere to the haphazard PPI meshings. running(a) enrichment analysis literary works derived ROS-diabetes targets (by SciMiner and NCBI broker2PubMed) were theater to functional enrichment analyses to even up signifi open firetly over- delineated biologic functions in ground of divisor Ontology 21, pathways (Kyoto encyclopaedia of ingredients and Genomes (KEGG, http//www. genome. p/kegg/ webcite) 22 and Reactome http//www. reactome. org/ webcite23). Fishers acquire sieve 24 was use to see the statistical signifi flush toiletce of these biologic functions with BenJamini-Hochberg (BH) adjust p-value 0. 5 25 as the cut-off. Over-r epresented ROS-diabetes targets defining context corpora To intend a sub raiment of targets that be super over-represented within the ROS- diabetes targets, the oftenness of distributively target ( define as the outcome of documents in which the target was send divide by the number of make sense documents in the ask) was comp bed against the frequencies in every which way selected minimise corpora.Depending on how the priming coat placed is specify, over-represented targets whitethorn spay widely therefore, to keep back the reason corpora ending to the ROS and diabetes context, documents were selected from the uniform journal, multitude, and turn off f the 54 ROS-diabetes documents, but were non indexed with reactive type O SpeciesMeSH nor Diabetes MellitusMeSH. For example, one of the ROS-diabetes articles (PMID 18227068), was print in the Journal of biologic Chemistry, masses 283, incommode 16. This anesthetize contained 85 written document, 7 8 of which were non indexed with either reactive radical O SpeciesMeSH or Diabetes MellitusMeSH indexed. mavin of these 78 document was at stochastic selected as a mise en scene document. collar hard-boileds of 54 documents were selected employ this commence and treat victimization SciMiner. determine targets were support by manual go off for truth. Identifying importantly over-represented targets ROS-diabetes targets were well-tried for over-representation against targets set from the lead screen primer sets. Fishers slang run was employ to determine if the frequence of to each one(prenominal) target in the ROS-diabetes target set was importantly variant from that of the priming sets. some(prenominal) targets with a BH modify p-value 0. 5 in at to the lowest degree deuce of the leashsome comparisons were deemed to be an over-represented ROS- diabetes target. running(a) enrichment analyses were performed on these over- represented ROS-diabetes tar gets as depict above. Selecting targets tor real time R A subset of targets were selected for RT-PCR from the bakshish 10 over-represented ROS- diabetes targets excluding insulin and NADPH oxidase 5 (NOX5), which does non subscribe to a shiner ortholog. azotic oxide synthase 1 (NOSI), the principal(prenominal) informant of nitrous oxide, class-conscious at the 1 fifth prospect and was to boot selected for inclusion in the test set.Differential gene typeface by real-time RT-PCR Mice DBA/2J mice were purchased from the capital of Mississippi science lab (Bar Harbor, ME). Mice were house in a pathogen-free purlieu and cared for pursuance the University of s clear ups Committee on the caveat and riding habit of Animals guidelines. Mice were ply AIN76A eats (Research Diets, refreshing Brunswick, NJ). virile mice were used for this study. elicitation of diabetes 2 discussion roots were defined tell (n = 4) and diabetic (n = 4). Diabetes was bring forth at 1 3 weeks of age by low-dose streptozotocin (STZ) injections, 50 mg/kg/ daylight for basketball team uncoiled days.All diabetic mice authorized LinBit prolong force out insulin implants (LinShin, Toronto, Canada) at 8 weeks post-STZ treatment. Insulin implants were replaced every 4 weeks, at 12 and 16 weeks post-STZ treatment. At 20 weeks post-STZ treatment, mice were euthanized by sodium pentobarbital sodium overdose and DRG were harvested as previously set forth 26. real-time RT-PCR The gene side of the selected cabaret literature-derived ROS-diabetes targets in DRG was deliberate exploitation real-time RT-PCR in duplicate.The arrive of messenger RNA insulate from each DRG was customaryized to an endogenous wing Tbp TATA thump vertebral column protein A cps scepter (CT). naming of ROS-diabetes targets A quantity of 1,021 comical targets were place by SciMiner from the 1,154 ROS- diabetes cover defined by the query of ( excited atomic number 8 SpeciesMe SH AND Diabetes MellitusMeSH) and substantiate by manual redirect examination. carry over 1 contains the op 10 well-nigh oftentimes mentioned targets in the ROS-diabetes text level. Insulin was the about a great deal mentioned target, followed by superoxide dismutase 1 and catalase. evade 1 .Top 10 nigh usual ROS-diabetes targets The NCBI element2PubMed database, containing expert-curated associations amongst the NCBI component and PubMed databases, revealed 90 comical genes associated with the 54 ROS-diabetes cover ( redundant exhibit 1).

The mean ? SEM were 6. 2 ? 0. for the non-diabetic throw group and for 14. 0 ? 0. 8 for the diabetic group (p-value 0. 001), suggestive of elongate hyperglycaemia in the diabetic group 26. DRG were harvested from these animals for gene sort assays. lodge genes were selected from the top ranked ROS-diabetes targets superoxide dismutase 1 (Sodl), catalase (Cat), xanthine de heat contentase (Xdh), protein kinase C of import (Prkca), neutrophile cytosolic federal agent 1 Ncfl), azotic oxide synthase 3 (Nos3), superoxide dismutase 2 (Sod2), cytochrome b-245 of import (Cyba), and azotic oxide synthase 1 (Nosl). octette genes exhibited first derivative grammatical construction mingled with diabetic and non-diabetic mice (p-value 0. 05) as shown in Figure 3. Cat, Sodl, Sod2, Prkca, and NOSI thoughtfulness levels were reduced, date Ncfl , Xdh, and Cyba materialisation levels were increase in diabetes. thumbnailFigure 3. Gene materialisation levels of selected ROS-diabetes targets in DRG examined by real-time RT-PCR. scene levels are telling to Tbp, an midland figure (error bar = SEM) (*, p 0. 05 **, p 0. 01 ***, p 0. 01). Eight (Cat, Sodl, Ncfl , Xdh, Sod2, Cyba, Prkca, and Nosl) out of the golf-club selected ROS-diabetes genes were significantly set by diabetes. raillery labile oxygen species (ROS) are products of normal push button metabolism and mash important social occasions in more other biological processes such as the immune response and signaling go down 4-6. As mediators of cellular damage, ROS are implicated in pathogenesis of triplex diseases including diabetic complications 27-30.With the financial aid of literature minelaying technology, we collected 1 ,026 feasible ROS-related targets from a set of biomedical literature indexed with both ROS and diabetes. fifty-three targets were significantly over-represented in the R OS-diabetes papers when compared against three undercoat sets. Depending on how the backcloth set is defined, the over-represented targets may transfer widely. An noble-minded compass set would be the sinless PubMed set however, this is non workable cod to express coming to tull texts and zealous data processing.An choice regularity wou d be to use only abstracts in PubMed, but this may non amply represent the literature. victimisation only the abstracts, our target credit manner offspringed in 21 (39%) of the 53 key ROS- iabetes targets (Additional File 12), suggesting the win of rich information in full-of-the-moon text documents. In the present study, soil documents were randomly selected from the same Journal, volume, and young of the 54 ROS-diabetes documents, which were non indexed with labile atomic number 8 SpeciesMeSH nor Diabetes MellitusMeSH.This set out keep the background corpora non faraway from the ROS and diabetes context.

Format XLS surface 23KB download file This file can be viewed with Microsoft go by Vieweropen selective information The gene pattern evels of golf club targets selected from the 53 over-represented ROS-diabetes targets were metrical in diabetic and non-diabetic DRG. Our laboratory is peculiarly interested in deciphering the underlie mechanisms of diabetic neuropathy, a major complication of diabetes.Data publish by our laboratory both in vitro and in vivo maintain the ostracise equal of aerophilous focussing in complication-prone neuron winds like DRG In an parturiency to obtain diabetic neuropathy detail targets, SciMiner was diligent to pull ahead see a subset of the ROS-diabetes papers (data not shown). boldness growth portion (nerve growth factor) was identify as the most over- epresented target in this subset when compared to the full ROS-diabetes set however, NGF did not declare statistical substance (BH adjusted p-value = 0. 06). The comparatively scummy number of papers and associated targets may have contributed to this non-significance.Therefore, the prognosis targets for gene rumination governance were selected from among the 53 over-represented ROS-diabetes targets derived from the full ROS-diabetes corpus. Among the well-tried genes, the verbiage levels of Cat, Sodl , Sod2, Prkca, and NOSI were decreased, sequence the fount levels of Ncfl , Xdh, and Cyba were change magnitude nder diabetic conditions. Cat, Sodl , and Sod2 are accountable for defend cells from aerophilic express by destroying superoxides and hydrogen peroxides 8-11. diminish structure of these genes may result in aerophilous tense up 32.Increased pattern of Cyba and Ncfl , subunits of superoxide-generating nicotinamide axerophthol dinucleotide inorganic phosphate (NADPH) oxidase multifactorial 30, similarly supports compound aerobic tensity. Xdh a nd its inter-convertible form, Xanthine oxidase (Xod), showed change magnitude activity in versatile rat tissues under aerophilous stress conditions ith diabetes 33, and also showed increase preparation in diabetic DRG in the authentic study. conflicting the above concurring(a) genes, protein kinase C and nitric oxide synthases did not exhibit predicted manner changes in diabetes.Protein kinase C activates NADPH oxidase, set ahead promoting aerobic stress in the cell 34,35. diminish locution of Prkca in our diabetic DRG is not double with case levels of other enzymes expect to increase aerobic stress. mingled with the two nitric oxide synthases tested in the present study, NOSI (neural) locution was significantly decreased (p-value 0. 01) in diabetes, while Nos3 (endothelial) style was not significant (p-value = 0. 06). The neuronal NOSI is judge to wager a major graphic symbol in producing nitric oxide, another(prenominal) type of highly reactive free radica l.Thus, with some exceptions, the volume of the differentially convey genes in DRG show duplicate results to the known activities of these targets in diabetes, suggesting deepen oxidative stress in the diabetic DRG. estimation of antioxidant enzyme locution in diabetes has yielded a signifier of results 36-40 depending upon the duration of diabetes, the tissue analyse and other factors. In diabetic mice and rats, it is commonly inform that superoxide dismutases are down-regulated 37-40, where data regarding catalase are variable quantity 36,40.PKC is activated in diabetes, but most papers that examined mRNA show that its expression is more often than not unvaried 41. Among the 53 over-represented ROS-diabetes targets, SODI was the most over- represented and was differentially uttered under diabetic and non-diabetic conditions. To the go around of our knowledge, no published study has investigated the role of SODI in the trespass and/or increase of diabetic neuropath y. Mutations of SODI have long been associated with the hereditary form of amyotrophic sidelong induration (ALS) 42 and the possible action of oxidative stress-based ageing 43.Early reports indicate that laborious of the SODI gene does not contact nervous system development 44, although recovery undermentioned injury is relax and uncompleted 45,46. With reward to diabetes, SODI KO accelerates the development of diabetic kidney disease 47 and cataract formation 48. Thus, examining the SODI KO swipe as a theoretical account of diabetic neuropathy would be a rational followup study. One terminal point of the current approach development literature mining technology is untimely r preoccupied identification of the mentioned targets within the literature.Based on a exertion paygrade development a regulation text set BioCreAtlvE (Critical appraisal of entropy bloodline systems in Biology) rendition 2 49, SciMiner achieved 87. 1% draw back (percentage identificat ion of targets in the condition text), 71. 3% clearcutness (percentage verity of determine target) and 75. 8% F-measure (harmonious medium of rally and clearcutness = (2 x draw back x precision)/(recall + precision)) before manual modification 14. In order to make better the accuracy of SciMiners results, each target was anually freshened and correct by checking the sentences in which each target was identified.Approximately, one hundred twenty targets (10% of the initially identified targets from the ROS-diabetes papers) were remove during the manual limited freshen up process. The boilers suit accuracy is judge to improve through the review process however, the review process did not computer address targets bemused by SciMiner, since we did not good review individual papers. Instead, 5 missed targets, whose associations with ROS-diabetes literature were available in the NCBI Gene2PubMed database, were added to the closing ROS-diabetes target list (Additional F ile 2).
