Mass spectrometry (MS) has been widely reported for measuring the conversion of substrates to products for enzyme assays and has more recently been demonstrated as an alternative readout system for inhibitor screening. In this report, a high-throughput mass spectrometry (HTMS) readout platform, based on the direct measurement of substrate conversion to product, is presented. The rapid ionization and desorption features of a new generation matrix-assisted laser desorption ionization-triple quadrupole (MALDI-QqQ) mass spectrometer are shown to improve the speed of analysis to greater than 1 sample per second while maintaining excellent Z′ values. Furthermore, the readout was validated by demonstrating the ability to measure IC50 values for several known kinase inhibitors against cyclic AMP–dependent protein kinase (PKA). Finally, when the assay performance was compared with a common ADPaccumulation readout system, this HTMS approach produced better signal-to-background ratios, higher Z′ values, and a reagent cost of about $0.03 per well compared with about $0.60 per well for the fluorescence assay. Collectively, these data demonstrate that a MALDI-QqQ-MS–based readout platform offers significant advantages over the commonly used assays in terms of speed, sensitivity, reproducibility, and reagent cost.

MAP is an essential bacterial gene product and thus represents a potential target for therapeutic intervention. A fundamental challenge in the antibacterial drug discovery field is demonstrating conclusively that compounds with in vitro enzyme inhibition activity produce the desired antibacterial effect by interfering with the same target in whole bacterial cells. One way to address the activity of inhibitor compounds is by profiling cellular biomarkers in whole bacterial cells using compounds that are known inhibitors of a particular target. However, in the case of MAP, no specific inhibitors were available for such studies. Instead, a genetically attenuated MAP strain was generated in which MAP expression was placed under the control of an inducible arabinose promoter. Thus, MAP inhibition in whole cells could be mimicked by growth in the absence of arabinose. This genetically attenuated strain was used as a benchmark for MAP inhibition by profiling whole-cell lysates for unprocessed proteins using surface-enhanced laser desorption ionization–time of flight mass spectrometry (MS). Eight proteins between 4 and 14 kDa were confirmed as being unprocessed and containing the initiator methionine by adding back purified MAP to the preparations prior to MS analysis. Upon establishing these unprocessed proteins as biomarkers for MAP inhibition, the assay was used to screen small-molecule chemical inhibitors of purified MAP for whole-cell activity. Fifteen compound classes yielded three classes of compound with whole-cell activity for further optimization by chemical expansion. This report presents the development, validation, and implementation of a whole-cell inhibition assay for MAP."],"license_tesim":["http://rightsstatements.org/vocab/InC/1.0/"],"date_created_tesim":["2005-09"],"source_tesim":["Antimicrobial Agents and Chemotherapy"],"thumbnail_path_ss":"/downloads/bc387096j?file=thumbnail","suppressed_bsi":false,"actionable_workflow_roles_ssim":["admin_set/default-default-depositing"],"workflow_state_name_ssim":["deposited"],"member_ids_ssim":["bc387096j"],"file_set_ids_ssim":["bc387096j"],"visibility_ssi":"open","admin_set_tesim":["Default Admin Set"],"sort_title_ssi":"DEVELOPMENT AND VALIDATION OF A WHOLECELL INHIBITION ASSAY FOR BACTERIAL METHIONINE AMINOPEPTIDASE BY SURFACEENHANCED LASER DESORPTION IONIZATIONTIME OF FLIGHT MASS SPECTROMETRY","human_readable_type_tesim":["Article"],"read_access_group_ssim":["public"],"read_access_person_ssim":["konecnmc@ucmail.uc.edu"],"edit_access_person_ssim":["greiskd@ucmail.uc.edu"],"nesting_collection__pathnames_ssim":["bc3870958"],"nesting_collection__deepest_nested_depth_isi":1,"_version_":1697120200378286080,"timestamp":"2021-04-15T15:19:06.955Z","score":0.00049999997},{"system_create_dtsi":"2017-10-27T02:52:19Z","system_modified_dtsi":"2018-08-01T18:40:05Z","has_model_ssim":["Article"],"id":"bc387093q","accessControl_ssim":["e9ed9a68-0457-46af-a360-a0e7df16b838"],"hasRelatedMediaFragment_ssim":["bc3870940"],"hasRelatedImage_ssim":["bc3870940"],"depositor_ssim":["greiskd@ucmail.uc.edu"],"depositor_tesim":["greiskd@ucmail.uc.edu"],"title_tesim":["A ROS-activatable agent elicits homologous recombination DNA repair and synergizes with pathway compounds"],"date_uploaded_dtsi":"2017-03-03T00:00:00Z","date_modified_dtsi":"2017-04-07T00:00:00Z","isPartOf_ssim":["admin_set/default"],"proxy_depositor_ssim":["dungavjk@mail.uc.edu"],"doi_tesim":["10.1002/cbic.201500304"],"journal_title_tesim":["ChemBioChem"],"college_tesim":["Medicine"],"department_tesim":["Cancer \u0026 Cell Biology"],"note_tesim":["This work was part of a pilot \"mediated-deposit model\" where library staff found potential works, later submitted for faculty review"],"creator_tesim":["Wunderlich, Mark","Mulloy, James C.","Greis, Kenneth D.","Merino, Edward J.","Thowfeik, Fathima Shazna","Wyder, Michael","AbdulSalam, Safnas F.","Kadekaro, Ana L."],"subject_tesim":["Cancer Biology"],"language_tesim":["English"],"description_tesim":["We have designed ROS-activated cytotoxic agents that are active against AML cancer cells.

We hypothesized that cMyBP-C is sensitive to proteolysis and is specifically increased in the bloodstream post-MI in rats and humans. Under these circumstances, elevated levels of degraded cMyBP-C could be used as a diagnostic tool to confirm MI. To test this hypothesis, we first established that cMyBP-C dephosphorylation is directly associated with increased degradation of this myofilament protein, leading to its release in vitro. Using neonatal rat ventricular cardiomyocytes in vitro, we were able to correlate the induction of hypoxic stress with increased cMyBP-C dephosphorylation, degradation, and the specific release of N′-fragments. Next, to define the proteolytic pattern of cMyBP-C post-MI, the left anterior descending coronary artery was ligated in adult male rats. Degradation of cMyBP-C was confirmed by a reduction in total cMyBP-C and the presence of degradation products in the infarct tissue. Phosphorylation levels of cMyBP-C were greatly reduced in ischemic areas of the MI heart compared to non-ischemic regions and sham control hearts. Post-MI plasma samples from these rats, as well as humans, were assayed for cMyBP-C and its fragments by sandwich ELISA and immunoprecipitation analyses. Results showed significantly elevated levels of cMyBP-C in the plasma of all post-MI samples. Overall, this study suggests that cMyBP-C is an easily releasable myofilament protein that is dephosphorylated, degraded and released into the circulation post-MI. The presence of elevated levels of cMyBP-C in the blood provides a promising novel biomarker able to accurately rule in MI, thus aiding in the further assessment of ischemic heart disease."],"license_tesim":["http://rightsstatements.org/vocab/InC/1.0/"],"date_created_tesim":["2012-01"],"source_tesim":["Journal of Molecular and Cellular Cardiology"],"thumbnail_path_ss":"/downloads/bc387092f?file=thumbnail","suppressed_bsi":false,"actionable_workflow_roles_ssim":["admin_set/default-default-depositing"],"workflow_state_name_ssim":["deposited"],"member_ids_ssim":["bc387092f"],"file_set_ids_ssim":["bc387092f"],"visibility_ssi":"open","admin_set_tesim":["Default Admin Set"],"sort_title_ssi":"CARDIAC MYOSIN BINDING PROTEINC IS A POTENTIAL DIAGNOSTIC BIOMARKER FOR MYOCARDIAL INFARCTION","human_readable_type_tesim":["Article"],"read_access_group_ssim":["public"],"read_access_person_ssim":["konecnmc@ucmail.uc.edu"],"edit_access_person_ssim":["greiskd@ucmail.uc.edu"],"nesting_collection__pathnames_ssim":["bc3870915"],"nesting_collection__deepest_nested_depth_isi":1,"_version_":1697114871270735872,"timestamp":"2021-04-15T13:54:24.722Z","score":0.00049999997},{"system_create_dtsi":"2017-10-27T02:52:10Z","system_modified_dtsi":"2018-08-01T18:40:11Z","has_model_ssim":["Article"],"id":"bc3870894","accessControl_ssim":["a26ae815-4a1d-44f2-a752-795d411711dd"],"hasRelatedMediaFragment_ssim":["bc387090w"],"hasRelatedImage_ssim":["bc387090w"],"depositor_ssim":["greiskd@ucmail.uc.edu"],"depositor_tesim":["greiskd@ucmail.uc.edu"],"title_tesim":["Cardiac Metabolic Pathways Affected in the Mouse Model of Barth Syndrome"],"date_uploaded_dtsi":"2017-03-03T00:00:00Z","date_modified_dtsi":"2017-04-07T00:00:00Z","isPartOf_ssim":["admin_set/default"],"proxy_depositor_ssim":["dungavjk@mail.uc.edu"],"doi_tesim":["10.1371/journal.pone.0128561"],"journal_title_tesim":["PLoS ONE"],"college_tesim":["Medicine"],"department_tesim":["Cancer \u0026 Cell Biology"],"note_tesim":["This work was part of a pilot \"mediated-deposit model\" where library staff found potential works, later submitted for faculty review"],"creator_tesim":["Haffey, Wendy D.","Mandala, Satish K.","Purevjav, Enkhsalkhan","Huang, Yan","Javadov, Sabzali","Greis, Kenneth D.","Powers, Corey","Strauss, Arnold W.","Towbin, Jeffrey A.","Khuchua, Zaza"],"subject_tesim":["Cancer Biology"],"language_tesim":["English"],"description_tesim":["Cardiolipin (CL) is a mitochondrial phospholipid essential for electron transport chain (ETC) integrity. CL-deficiency in humans is caused by mutations in the tafazzin (Taz) gene and results in a multisystem pediatric disorder, Barth syndrome (BTHS). It has been reported that tafazzin deficiency destabilizes mitochondrial respiratory chain complexes and affects supercomplex assembly. The aim of this study was to investigate the impact of Taz-knockdown on the mitochondrial proteomic landscape and metabolic processes, such as stability of respiratory chain supercomplexes and their interactions with fatty acid oxidation enzymes in cardiac muscle. Proteomic analysis demonstrated reduction of several polypeptides of the mitochondrial respiratory chain, including Rieske and cytochrome c1 subunits of complex III, NADH dehydrogenase alpha subunit 5 of complex I and the catalytic core-forming subunit of F0F1-ATP synthase. Taz gene knockdown resulted in upregulation of enzymes of folate and amino acid metabolic pathways in heart mitochondria, demonstrating that Tazdeficiency causes substantive metabolic remodeling in cardiac muscle. Mitochondrial respiratory chain supercomplexes are destabilized in CL-depleted mitochondria from Taz knockdown hearts resulting in disruption of the interactions between ETC and the fatty acid oxidation enzymes, very long-chain acyl-CoA dehydrogenase and long-chain 3-hydroxyacylCoA dehydrogenase, potentially affecting the metabolic channeling of reducing equivalents between these two metabolic pathways. Mitochondria-bound myoglobin was significantly reduced in Taz-knockdown hearts, potentially disrupting intracellular oxygen delivery to the oxidative phosphorylation system. Our results identify the critical pathways affected by the Taz-deficiency in mitochondria and establish a future framework for development of therapeutic options for BTHS."],"license_tesim":["http://rightsstatements.org/vocab/InC/1.0/"],"date_created_tesim":["2015-06"],"source_tesim":["PLoS ONE"],"thumbnail_path_ss":"/downloads/bc387090w?file=thumbnail","suppressed_bsi":false,"actionable_workflow_roles_ssim":["admin_set/default-default-depositing"],"workflow_state_name_ssim":["deposited"],"member_ids_ssim":["bc387090w"],"file_set_ids_ssim":["bc387090w"],"visibility_ssi":"open","admin_set_tesim":["Default Admin Set"],"sort_title_ssi":"CARDIAC METABOLIC PATHWAYS AFFECTED IN THE MOUSE MODEL OF BARTH SYNDROME","human_readable_type_tesim":["Article"],"read_access_group_ssim":["public"],"read_access_person_ssim":["konecnmc@ucmail.uc.edu"],"edit_access_person_ssim":["greiskd@ucmail.uc.edu"],"nesting_collection__pathnames_ssim":["bc3870894"],"nesting_collection__deepest_nested_depth_isi":1,"_version_":1697122167359012864,"timestamp":"2021-04-15T15:50:22.814Z","score":0.00049999997},{"system_create_dtsi":"2017-10-27T02:52:05Z","system_modified_dtsi":"2018-08-01T18:40:07Z","has_model_ssim":["Article"],"id":"bc387087k","accessControl_ssim":["5b824e71-18ef-430f-89d9-6ab268c5b92e"],"hasRelatedMediaFragment_ssim":["bc387088v"],"hasRelatedImage_ssim":["bc387088v"],"depositor_ssim":["greiskd@ucmail.uc.edu"],"depositor_tesim":["greiskd@ucmail.uc.edu"],"title_tesim":["Mechanism of insulin sensitization by BMOV (bis maltolato oxo vanadium); unliganded vanadium (VO4) as the active component"],"date_uploaded_dtsi":"2017-03-01T00:00:00Z","date_modified_dtsi":"2017-04-07T00:00:00Z","isPartOf_ssim":["admin_set/default"],"proxy_depositor_ssim":["dungavjk@mail.uc.edu"],"doi_tesim":["10.1016/S0162-0134(03)00236-8"],"journal_title_tesim":["Journal of Inorganic Biochemistry"],"college_tesim":["Medicine"],"department_tesim":["Cancer \u0026 Cell Biology"],"note_tesim":["This work was part of a pilot \"mediated-deposit model\" where library staff found potential works, later submitted for faculty review"],"creator_tesim":["Diven, Conrad","Peters, Kevin G.","Evdokimov, Artem","Howard, Brian W.","Soper, Shari","Genbauffe, Frank","Greis, Kenneth D.","Rastogi, Vinit","Eby-Wilkens, Elaine","Pokross, Matthew","Maier, Matthew"],"subject_tesim":["Biology","Biochemistry"],"language_tesim":["English"],"description_tesim":["Organovanadium compounds have been shown to be insulin sensitizers in vitro and in vivo.

The repeating PO4-6Galp beta 1-4Man disaccharide units, which are a salient feature of the molecule, are shown to terminate with one of several neutral structures, the most abundant of which is the branched trisaccharide Galp beta 1-4(Manp alpha 1-2)Man. The phosphosaccharide core of lipophosphoglycan, which links the disaccharide repeats to a lipid anchor, contains 2 phosphate residues. One of the core phosphates has previously been localized on O-6 of the galactosyl residue distal to the lipid anchor; the second phosphate is now shown to be on O-6 of the mannosyl residue distal to the anchor and to bear an alpha-linked glucopyranosyl residue. Also, the anomeric configuration of the unusual 3-substituted Galf residue in the phosphosaccharide core is established as beta. The complete structure of the core is thus PO4-6Galp alpha 1-6Galp alpha 1-3Galf beta 1-3[Glcp alpha 1-PO4-6]Manp alpha 1-3Manp alpha 1-4GlcN alpha 1-.

The detection and analysis of these low-level proteins is hindered by the presence of a few proteins that are expressed in relatively high concentrations. In the case of muscle tissue, highly abundant structural proteins, such as actin, myosin, and tropomyosin, compromise the detection and analysis of more biologically relevant proteins. We have developed a practical protocol which exploits high-pH extraction to reduce or remove abundant structural proteins from skeletal muscle crude membrane preparations in a manner suitable for two dimensional gel electrophoresis. An initial whole-cell muscle lysate is generated by homogenization of powdered tissue in Tris-base. This lysate is subsequently partitioned into a supernatant and pellet containing the majority of structural proteins. Treatment of the pellet with high-pH conditions effectively releases structural proteins from membrane compartments which are then removed through ultracentrifugation. Mass spectrometric identification shows that the majority of protein spots reduced or removed by high-pH treatment were contractile proteins or contractile-related proteins. Removal of these proteins enabled successful detection and identification of minor proteins. Structural protein removal also results in significant improvement of gel quality and the ability to load higher amounts of total protein for the detection of lower abundant protein classes."],"license_tesim":["http://rightsstatements.org/vocab/InC/1.0/"],"date_created_tesim":["2005-06"],"source_tesim":["Electrophoresis"],"thumbnail_path_ss":"/downloads/bc387080n?file=thumbnail","suppressed_bsi":false,"actionable_workflow_roles_ssim":["admin_set/default-default-depositing"],"workflow_state_name_ssim":["deposited"],"member_ids_ssim":["bc387080n"],"file_set_ids_ssim":["bc387080n"],"visibility_ssi":"open","admin_set_tesim":["Default Admin Set"],"sort_title_ssi":"EFFECTIVE SKELETAL MUSCLE PREFRACTIONATION METHOD TO REMOVE ABUNDANT STRUCTURAL PROTEINS FOR OPTIMIZED TWODIMENSIONAL GEL ELECTROPHORESIS","human_readable_type_tesim":["Article"],"read_access_group_ssim":["public"],"read_access_person_ssim":["konecnmc@ucmail.uc.edu"],"edit_access_person_ssim":["greiskd@ucmail.uc.edu"],"nesting_collection__pathnames_ssim":["bc387079w"],"nesting_collection__deepest_nested_depth_isi":1,"_version_":1697089686670934016,"timestamp":"2021-04-15T07:14:06.816Z","score":0.00049999997}],"facets":[{"name":"human_readable_type_sim","items":[{"value":"Image","hits":4793,"label":"Image"},{"value":"Dataset","hits":3723,"label":"Dataset"},{"value":"Etd","hits":994,"label":"Etd"},{"value":"Document","hits":978,"label":"Document"},{"value":"Article","hits":963,"label":"Article"},{"value":"Student Work","hits":755,"label":"Student Work"}],"label":"Human Readable Type Sim"},{"name":"creator_sim","items":[{"value":"Snider, Jerry A.
