Electronic volume analysis of L1210 chemotherapy. (1/6280)

The rapid analysis of in vivo chemotherapy on the L1210 ascites tumor grown in C57BL/6 X DBA/2F1 mice has been shown by means of an electronic volume analysis. The drugs were injected on the 4th day of tumor growth, and the cells in the peritoneal cavity were studied at 24-hr intervals on the 5th through 7th day. Using the electronic cell volume distributions, combined with labeling indices, cell morphology, and cell counts, it was found that the alkylating agents. 1,3-bis(2-chloroethyl)-1-nitrosourea and cyclophosphamide, at the dosages used, were more effective than the S-phase-specific drugs, palmitoyl ester of 1-beta-D-arabinofuranosylcytosine, vincristine, and methotrexate.  (+info)

Fluorimetric multiparameter cell assay at the single cell level fabricated by optical tweezers. (2/6280)

A fluorimetric multi-parameter cell sensor at the single cell level is presented which makes it possible to observe the physiological behavior of different cell lines, different physiological parameters, and statistical data at the same time. Different cell types were immobilized at predefined positions with high accuracy using optical tweezers and adhesion promoting surface layers. The process is applicable to both adherent and non-adherent cells. Coating of the immobilization area with mussel adhesive protein was shown to be essential for the process. Intracellular proton and calcium concentrations in different cell classes were simultaneously imaged and the specific activation of T lymphocytes was demonstrated. This method should be especially useful for drug screening due to the small sample volume and high information density.  (+info)

Immunising potency of Leptospira interrogans serotype canicola after heat inactivation at different temperatures. (3/6280)

The immunogenicity of Leptospira interrogans serotype canicola suspensions inactivated by various degrees of heat exposure was examined in hamsters. No differences between leptospires killed at 50 degrees C and at 98 degrees C were shown. After exposure to 121 degrees C, suspensions retained their ability to protect against lethal infections but lost their ability to prevent leptospiruria. Tests with vaccines inactivated at or below 98 degrees C showed that the doses required for complete protection varied with the interval between vaccination and challenge. Larger doses were required to prevent the development of leptospiruria than to prevent death.  (+info)

Micronucleus test using cultured new born rat astrocytes. (5/6280)

Micronuclei is induced in cytoplasm as a consequence of the formation of chromosomal fragments or remaining chromosomes during cell division by the cause of clastogens or spindle poisons, and is used as an indicator of genotoxicity screening tests. There are few short-term genotoxicity screening tests using brain cells. We attempted to establish a new in vitro micronucleus test (MN test) system by use of central nervous system cells. Primary cultured astrocytes were prepared from newborn male Sprague-Dawley (SD) rats. In growth curve of astrocytes, doubling time was determined to be 31 h. In time study, the highest frequency of micronuclei was observed at 48 h, 72 h and 6 h-exposure-66 h-recovery by vincristine (VCR), mitomycin C (MMC) without metabolic activation system and cyclophosphamide (CPM) with metabolic activation system, respectively. Dose-response relationships between micronucleus frequency and concentrations of MMC, VCR and CPM were observed, respectively. It is suggested that the in vitro MN test using new born rat-astrocytes could be used as a screening test of environmental and occupational genotoxic chemicals in the central nervous system cells.  (+info)

Recombinant soluble form of PSGL-1 accelerates thrombolysis and prevents reocclusion in a porcine model. (6/6280)

BACKGROUND: We investigated whether administration of a soluble recombinant P-selectin glycoprotein ligand-1 chimera (rPSGL-Ig) in conjunction with thrombolytic therapy would enhance thrombolysis by preventing ongoing interactions of leukocytes with platelets and the injured arterial wall. METHODS AND RESULTS: An occlusive thrombus was formed in an internal iliac artery of Yorkshire pigs by placement of a copper coil in the artery under fluoroscopic guidance. Pigs then received heparin and, 15 minutes later, either vehicle or rPSGL-Ig followed by infusion with 25 mg tissue plasminogen activator according to the 90-minute regimen. Blood flow through the artery was monitored by angiography and scored on a scale of 0 to 3. Lysis of the thrombus was accelerated by 70% in pigs treated with rPSGL-Ig 250 microg/kg compared with control (13.3+/-5.0 versus 44. 4+/-13.3 minutes; n=9 each). Eight of 9 control pigs reoccluded in 13.8+/-16.9 minutes after the end of tissue plasminogen activator infusion, whereas no reocclusion was observed in 8 of 9 pigs in the rPSGL-Ig group. When the dose of rPSGL-Ig was increased to 500 microg/kg, time to lysis was shortened by 61% from control (18.0+/-8. 4 versus 46.0+/-8.9 minutes). Reocclusion occurred in 6.0+/-15.2 minutes in control but not in any rPSGL-Ig-treated pig (n=5 each). In addition, near-normal flow (score 2 or 3) after thrombolysis was achieved 59% and 58% faster in the 2 rPSGL-Ig groups than in their respective controls. CONCLUSIONS: Inhibition of leukocyte accumulation at the site of thrombosis with rPSGL-Ig may represent a safe therapeutic intervention that could be important in accelerating thrombolysis, achieving optimal reperfusion, and reducing incidence of acute reocclusion.  (+info)

Recovery of the vestibulocolic reflex after aminoglycoside ototoxicity in domestic chickens. (7/6280)

Avian auditory and vestibular hair cells regenerate after damage by ototoxic drugs, but until recently there was little evidence that regenerated vestibular hair cells function normally. In an earlier study we showed that the vestibuloocular reflex (VOR) is eliminated with aminoglycoside antibiotic treatment and recovers as hair cells regenerate. The VOR, which stabilizes the eye in the head, is an open-loop system that is thought to depend largely on regularly firing afferents. Recovery of the VOR is highly correlated with the regeneration of type I hair cells. In contrast, the vestibulocolic reflex (VCR), which stabilizes the head in space, is a closed-loop, negative-feedback system that seems to depend more on irregularly firing afferent input and is thought to be subserved by different circuitry than the VOR. We examined whether this different reflex also of vestibular origin would show similar recovery after hair cell regeneration. Lesions of the vestibular hair cells of 10-day-old chicks were created by a 5-day course of streptomycin sulfate. One day after completion of streptomycin treatment there was no measurable VCR gain, and total hair cell density was approximately 35% of that in untreated, age-matched controls. At 2 wk postlesion there was significant recovery of the VCR; at this time two subjects showed VCR gains within the range of control chicks. At 3 wk postlesion all subjects showed VCR gains and phase shifts within the normal range. These data show that the VCR recovers before the VOR. Unlike VOR gain, recovering VCR gain correlates equally well with the density of regenerating type I and type II vestibular hair cells, except at high frequencies. Several factors other than hair cell regeneration, such as length of stereocilia, reafferentation of hair cells, and compensation involving central neural pathways, may be involved in behavioral recovery. Our data suggest that one or more of these factors differentially affect the recovery of these two vestibular reflexes.  (+info)

Coating titanium implants with bioglass and with hydroxyapatite. A comparative study in sheep. (8/6280)

This study compares the osteointegration of titanium implants coated with bioglass (Biovetro GSB formula) and with hydroxyapatite (HAP). Twenty-four bioglass-coated and 24 HAP-coated cylinders were implanted in the femoral diaphyses of sheep, and examined after 2, 4, 6, 8, 12, and 16 weeks. The HAP coating gave a stronger and earlier fixation to the bone than did bioglass. Bioglass formed a tissue interface which showed a macrophage reaction with little new bone formation activity. In contrast, HPA, showed intense new bone formation, with highly mineralised osseous trabeculae in the neighbourhood of the interface.  (+info)

The clinical utility of proteasome inhibitors as treatment for multiple myeloma and non-Hodgkins lymphoma (NHL) has been validated with two parenterally administered agents: bortezomib, a dipeptide boronate that was approved by the FDA in 2003; and carfilzomib, a tetrapeptide epoxyketone that has shown promising activity in Phase 1 clinical trials. The clinical development of an orally bioavailable proteasome inhibitor would offer improvement in both dosing flexibility and patience convenience over intravenous (IV) administration. Furthermore, oral administration will allow a practical approach to investigating the affect of prolonged proteasome inhibition by repeated daily dosing in patients with advanced malignancies. Here we describe the preclinical pharmacology of PR-047, a tripeptide epoxyketone that was selected through a medicinal chemistry effort designed to find a selective inhibitor of the chymotrypsin-like (CT-L) activity of the proteasome that combined the efficacy and safety of ...

Challenge 1: Redesign Research Pipeline. Clinical trials have yet to reveal an effective therapy for most brain tumours. This harsh reality stems, in part, from an incomplete understanding of brain tumour biology and the existence of a disconnect between preclinical drug development and rigorous testing in the clinic. Each element of the brain tumour research pipeline, from basic neurobiology to clinical trials, requires careful scrutiny and increased investment, although the development of an overarching strategy that facilitates and promotes interdisciplinary research is equally important . This strategy would bring an end to the previous siloed organization of working practices, in which basic and clinical researchers performed their studies independently and collaborated only when laboratory research was judged to be ready for the clinic or when the laboratory is engaged to understand the reasons why a promising drug failed to achieve the expected level of efficacy in clinical trials. Much ...

Activating KRAS mutations are commonly seen in 40% to 50% of human CRC (13). Although the prognostic role of such mutations is controversial, it is evident that they are powerful positive predictors for resistance to treatment with anti-EGFR therapies, such as cetuximab or panitumumab (14, 15). Because of the central role for KRAS in EGFR and other receptor tyrosine kinase signaling pathways during CRC carcinogenesis (16), robust KRAS-specific treatments are desperately needed for effective CRC treatment. As such efforts have been widely unsuccessful to date (17), the development of novel therapeutic approaches for treatment of KRAS-mutant CRC is a critical unmet clinical need.. Despite the identification of many candidate drug compounds during preclinical discovery efforts, the subsequent rate of success through the clinical trial pipeline is abysmal (18). Traditional preclinical drug discovery platforms often rely on genetically undefined and highly passaged human tumor cell lines. The in ...

Preclinical pharmacokinetic models capable of predicting concentrations/exposure in vivo under different dosing schema can provide an invaluable tool for the rational design of clinical dosing protocols. The overall goals of the studies described herein were to design and evaluate the use of rational dosing protocols for vandetanib, docetaxel, and combinations of the two using pharmacokinetically directed dosing protocols that were reflective of exposures attainable in humans and that target antitumor and antiangiogenic responses. We utilized a PBPK model for docetaxel to develop dosing protocols that would allow us to examine the effects of standard docetaxel treatment versus a metronomic or antiangiogenic schedule of docetaxel. Pharmacokinetic data on vandetanib was used to determine a steady-state dose level that was reflective of human vandetanib exposure (32).. Preclinical testing is an integral part of the development of new therapeutics and new therapeutic strategies. With increasing ...
HOUSTON -- (March 15, 2010) -- The film Avatar isnt the only 3-D blockbuster making a splash this winter. A team of scientists from Houstons Texas Medical Center this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testing costs. The research is reported in Nature Nanotechnology. The 3-D technique is easy enough for most labs to set up immediately. It uses magnetic forces to levitate cells while they divide and grow. Compared with cell cultures grown on flat surfaces, the 3-D cell cultures tend to form tissues that more closely resemble those inside the body. Theres a big push right now to find ways to grow cells in 3-D because the body is 3-D, and cultures that more closely resemble native tissue are expected to provide better results for preclinical drug tests, said study co-author Tom Killian, associate professor of physics at Rice. If you could improve the accuracy of early drug ...
Aberrant signaling through Fibroblast Growth Factor Receptors (FGFR) has been reported in multiple types of human cancers. FGFR4 signaling contributes to the development and progression of subsets of cancer: in approximately 10 percent of hepatocellular carcinoma (HCC), genetic amplification of FGF19, encoding an endocrine FGF ligand that activates FGFR4-KLB receptors, has been reported. In models with this alteration, FGF19-FGFR4 signaling is oncogenic and antagonism of the FGF19-FGFR4 axis has been shown to be efficacious suggesting that selective targeting of FGFR4 may be an effective strategy for malignancies with FGFR4 activation.. We describe the preclinical characterization of INCB062079 a potent and selective inhibitor of the FGFR4 kinase. In biochemical assays INCB062079 inhibited FGFR4 with low nM potency and exhibited at least 250-fold selectivity against other FGFR kinases and greater than 800-fold selectivity against a large kinase panel. This selectivity derives from the ability of ...

Koen Dechering of TropIQ Health Sciences in the Netherlands is developing a high-throughput functional assay to identify new compounds that specifically block transmission of the malaria parasites to their vector hosts, which is a difficult stage to target, and to test candidate drugs. The assay incorporates luciferase- expressing parasites, which emit light as they develop in the mosquito midgut, along with barcoded chemical libraries. In Phase I, they tested several barcoding strategies and identified a bacterium that could be genetically modified to carry a unique barcode for identifying hit compounds selected in the screen. They also developed the luminescent reporter parasite to track transmission. In Phase II, they will further develop the assay for higher throughput, and screen compounds from the Tres Cantos Antimalarial Set and the MMV Validation, Malaria and Pathogen boxes. They will also use the assay to characterize the mechanisms of action of other candidate transmission-blocking ...

Although the scientific community continues to combat male bias in preclinical research, representation of women in late-phase clinical trials has improved markedly in recent years.21 The National Institutes of Health initiative to increase the use of female organisms and cells in preclinical research ensures that the scientific community as a whole will grow to fully address the health of both men and women. A major obstacle to the incorporation of female animals into studies, however, has been the belief that the rodent estrous cycle would render the study of these animals prohibitively expensive or difficult. Our study shows for the first time in a single large data set of physiological measurements that this belief is not accurate.. Our findings show that sex differences in CV among rats are small despite hormone fluctuations because of the estrous cycle. Moreover, for the majority of phenotypes, cohorts larger than typically used in preclinical research are required to detect the sex ...
A new drug candidate is more likely to be approved for use if it targets a gene known to be linked to the disease; a finding that can help pharmaceutical companies to focus their drug development efforts.

Confidence Beyond Compliance. Regulatory agencies offer sponsors guidance and regulations on what data is required for a products development, but there is not always clarity on when these studies need to be completed in respect to an investigational products stage of development. Furthermore, while ICH guidelines provide structure to global non-clinical strategies, there are often nuances to regional study design and execution that should be considered. While non-clinical efforts are most often associated with the objective of reaching first-in-man studies, non-clinical programs run the lifecycle of the drug development process. PharmaLex assists its clients by working closely with them to carefully balance what is required for each stage of development and registration while considering the variables of time and cost..

Laromustine is an experimental sulfonylhydrazine prodrug used in late-stage clinical studies against acute myeloid leukemia (AML) and glioblastoma multiforme (GBM). Despite initial promise for both indications, clinical trials for GBM have not been as successful as those for AML. To investigate methods for improving the effectiveness of laromustine in GBM and to learn more about the mechanism of action of laromustine, a chemical genetic screen will be conducted to identify agents that sensitize GBM cells to the anti-proliferative effects of laromustine. The library, which will include approximately 450 FDA-approved drugs, will be screened using a newly optimized high throughput assay based on the Click-iT EdU Microplate Assay kit (Molecular Probes). Optimization of the assay has required determining the proper cell seed density, drug concentration and incubation time, and fluorescent substrate concentration, among other variables. It was determined that low cell seed densities allow for maximal

Due to the promising early results seen in patients with primary brain cancer, Reata has begun clinical trials of RTA 744 in patients who have other types of tumors (for example, lung or breast cancer) that have spread to the central nervous system (CNS). Reata Pharmaceuticals, Inc. is a biopharmaceutical company focused on developing novel treatments for cancer, inflammation, and neurodegenerative diseases. Reata is matching its clinical and preclinical drug development programs with a best-of-class drug discovery platform to identify small molecule chaperones that can induce proper folding of p53, SOD, and Tau, misfolded proteins that are involved in cancer and neurodegenerative disease.
Small-molecule microarrays composed of tens of thousands of distinct synthetic molecules, natural products, and their combinations/modifications provide a high-throughput platform for studying protein-ligand interactions. Immobilization of small molecule compounds on solid supports remains a challenge as widely varied small molecules generally lack unique chemical groups that readily react with singly or even multiply functionalized solid support. We explored two strategies for immobilizing small molecule compounds on epoxy-functionalized glass surface using primary-aminecontaining macromolecular scaffolds: bovine serum albumin (BSA) and amine-modified poly-vinyl alcohol (PVA). Small molecules with N-hydroxysuccinimide (NHS) groups were conjugated to BSA or amine-modified PVA. Small-molecule-BSA conjugates and small-molecule-PVA conjugates were subsequently immobilized on epoxy-functionalized glass slides through amine-epoxy reactions. Using an oblique-incidence reflectivity difference (OI-RD) ...

TY - JOUR. T1 - Preclinical assessment of infant formula. AU - Lönnerdal, Bo. PY - 2012/6. Y1 - 2012/6. N2 - Infant formulas are the sole or predominant source of nutrition for many infants and are fed during a sensitive period of development and may therefore have short- and long-term consequences for infant health. Preclinical safety assessment therefore needs to include both short-term and long-term studies in animals. It is recommended that procedures are instituted by which experts may serve as independent scientists for companies developing novel products, without having their integrity compromised, and later serve the legislative institutions. A two-level assessment approach to determine the potential toxicity of a novel ingredient, its metabolites, and their effects in the matrix on developing organ systems has been suggested by IOM. This appears reasonable, as novel ingredients can be of different levels of concern. The use of modern methods in genomics and proteomics should be ...
AKT is frequently deregulated in cancer, making it an attractive anticancer drug target. CCT128930 is a novel ATP-competitive AKT inhibitor discovered using fragment-and structure-based approaches. It is a potent, advanced lead pyrrolopyrimidine compound exhibiting selectivity for AKT over PKA, achieved by targeting a single amino acid difference. CCT128930 exhibited marked antiproliferative activity and inhibited the phosphorylation of a range of AKT substrates in multiple tumor cell lines in vitro, consistent with AKT inhibition. CCT128930 caused a G(1) arrest in PTEN-null U87MG human glioblastoma cells, consistent with AKT pathway blockade. Pharmacokinetic studies established that potentially active concentrations of CCT128930 could be achieved in human tumor xenografts. Furthermore, CCT128930 also blocked the phosphorylation of several downstream AKT biomarkers in U87MG tumor xenografts, indicating AKT inhibition in vivo. Antitumor activity was observed with CCT128930 in U87MG and ...

MNP001 is a newly synthesized 3-carbamyl-4-methylpyrrole analog with dual pharmacophores simultaneously to inhibit phosphodiesterase type 4 (PDE4) and to antagonize L-type calcium channels. The physicochemical properties of MNP001, including solubility, pKa, Log P, plasma protein binding and plasma/blood partitioning, were determined to support the pharmacokinetic characterization. The preclinical pharmacokinetic parameters were determined in an in vivo rat model and the metabolic pathways of MNP001 were characterized by incubating the compound in vitro in rat or human microsomes/supersomes cocktails. MNP001 was found to have a low solubility in simulated intestinal fluid but a high solubility in simulated gastric fluid. MNP001 is a highly lipophilic compound with a Log P value greater than 4. MNP001 was highly bound to the plasma protein and had an uneven partition between red blood cells and plasma. MNP001 exhibited a rapid absorption, broad distribution, slow systemic clearance and a low but
The PI3K pathway, which is commonly altered in numerous cancers (Liu et al., 2009a), has been identified as a promising target for the treatment of malignancies. Components of this signaling pathway, such as PI3K or mTOR, can be targeted by small molecules, and several inhibitors specific for one of these two kinases are being evaluated in patients (Engelman, 2009). Inhibitors of mTOR (mTORC1), referred to as rapalogs, have been approved for the treatment of cancers, and numerous dual PI3K/mTOR inhibitors are currently in clinical trials (Benjamin et al., 2011).. Preclinical pharmacokinetic studies provide key parameters during the discovery and the early stages of development of a compound. These parameters help to assess whether sufficient exposure can be achieved in further animal studies (efficacy and toxicology) and also are used to predict pharmacokinetic properties in humans. In addition, when integrated with efficacy data in PK-PD models, they can be used to estimate efficacious and ...
Rationale: Despite four decades of intense effort and substantial financial investment, the cardioprotection field has failed to deliver a single drug that effectively reduces myocardial infarct size in patients. A major reason is insufficient rigor and reproducibility in preclinical studies. Objective: To develop a multicenter randomized controlled trial (RCT)-like infrastructure to conduct rigorous and reproducible preclinical evaluation of cardioprotective therapies. Methods and Results: With NHLBI support, we established the Consortium for preclinicAl assESsment of cARdioprotective therapies (CAESAR), based on the principles of randomization, investigator blinding, a priori sample size determination and exclusion criteria, appropriate statistical analyses, and assessment of reproducibility. To validate CAESAR, we tested the ability of ischemic preconditioning (IPC) to reduce infarct size in three species (at two sites/species): mice (n=22-25/group), rabbits (n=11-12/group), and pigs ...
In early drug discovery (e.g., in fragment screening), recognition of stereoisomeric structures is valuable and guides medicinal chemists to focus only on useful configurations. In this work, we concurrently screened mixtures of stereoisomers and estimated their affinities to a protein target (thrombin) using weak affinity chromatography-mass spectrometry (WAC-MS). Affinity determinations by WAC showed that minor changes in stereoisomeric configuration could have a major impact on affinity. The ability of WAC-MS to provide instant information about stereoselectivity and binding affinities directly from analyte mixtures is a great advantage in fragment library screening and drug lead development.

Downloadable! This paper studies the interdependence of households? financial assets and liabilities in European countries. Most studies treat household liabilities as negative assets and relate households? decisions to their net wealth. However, the components of net wealth, i.e. financial liabilities, financial assets and real assets are very heterogeneous across households. The assumption of similar consumption behaviour among households with the same net wealth but different wealth components is implausible. This paper raises another question, namely whether households consider their indebtedness when they make decisions about their financial assets. The implication of household indebtedness for household behaviour is an important topic as household debt volumes have increased markedly in developed countries over the last three decades. There is a long list of research about household borrowing and the financial vulnerability of indebted households, but there has been less discussion about whether
Lundbeck divests preclinical research programs Two programs outside Lundbecks areas of focus are transferred to MindImmune Therapeutics, Inc. H. Lundbeck A/S (Lundbeck) further focuses its preclinical research pipeline with the divestment of two research programs to biotech company MindImmune Therapeutics, Inc. (MindImmune). In exchange for the programs, Lundbeck receives an equity interest in MindImmune as well as milestone payments and royalties according to the progression of the programs. The agreement follows Lundbecks strategy of focusing its efforts within four disease areas; depression, schizophrenia, Alzheimers disease and Parkinsons disease, for which the programs are not relevant. Per its strategy Lundbeck itself has therefore not prioritized further development of the programs, but the agreement ensures that these potential new treatments will now be brought forward. There will be no costs for Lundbeck associated with the future development of the programs. We focus on ...

Virtual drug screening is one of the most widely used approaches for finding new drugs candidates. The process consists in selecting one or more chemical compounds with the highest binding free energy to target proteins. Given that the empirical space of chemical compounds is extremely large and estimated to has over 50 millions of them, finding the most effective drug becomes computationally challenging. Furthermore, the vast majority of proteins still lack the experimentally obtained 3D structures required for most of the molecular computer tools available, making it impossible to calculate their binding free energies with chemical compounds. In view of this, the aim of our study is to asses the effectiveness of the Autodock Vina tool in a large environments with unstructured proteins, those without defined 3D structure. The ultimate goal is to enable a fast and efficient virtual drug screening in such an environments, and to apply it for discovery of a new drug candidates.. ...

In 2009, the same development team created Adam, a robot scientist that became the first machine to independently discover new scientific knowledge. They used the knowledge from that experiment to create Eve with the purpose of speeding up the drug discovery process and make it more economical. In the published study, the researchers discuss describe how the robot is able to identify promising new drug candidates for malaria and other neglected tropical diseases, such as African sleeping sickness and Chagas disease.. Neglected tropical diseases are a scourge of humanity, infecting hundreds of millions of people, and killing millions of people every year, said Steve Oliver, a professor from the Cambridge Systems Biology Centre and the Department of Biochemistry at the University of Cambridge. We know what causes these diseases and that we can, in theory, attack the parasites that cause them using small molecule drugs. But the cost and speed of drug discovery and the economic return make them ...

Most preclinical studies that aim to prove the antistroke efficacy of candidate drugs are performed in experimental settings bearing little-if any-resemblance to clinical reality, which is a possible reason for several neuroprotective drug failures (36,37). Potential causes of this lack of success include use of preclinical drug administration paradigms not achievable at the clinic level (e.g., drug administration before or very shortly after stroke, intracerebroventricular injections, and too-high doses of the candidate drugs (38)), efficacy experiments performed using animal models that lack common comorbidities of stroke patients, such as diabetes and hypertension (36), and finally, nearly all rodent stroke studies are performed in young animals, whereas most stroke patients are elderly (39).. Our goal in the current study was to determine the potential antistroke efficacy of a DPP-4 inhibitor therapy by mimicking the likely clinical scenario of an obese type 2 diabetic patient receiving this ...

Next, an unlabeled compound was analyzed using the kinetic probe competition assay. The reaction contained fluorescent tracer 178 and the indicated concentrations of staurosporine, an unlabelled ABL-binder. The reaction was started by adding Tb-labelled ABL resulting in a signal increase for the trace without competitor (Fig. 3, grey). In contrast, the signal in presence of the competitor is lower the higher its concentration, and the initial signal increase is followed by a decrease in signal over time. The latter indicates that due to slower binding kinetics the competitor equilibrates more slowly than the tracer. ...
Herein are a collection of studies that build on our existing knowledge of estrogen actions in the brain. We extend the efforts of current neuroprotective strategies by demonstrating that estrogenic molecules promote cell survival mechanisms governed by neuronal mitochondria. Estrogen (E2, 17beta-estradiol) protects neurons from a series of age-related risk factors for developing Alzheimer s disease (AD) supported by basic science, clinical, and epidemiological data. However, there exists a window of opportunity for E2 as a preventive therapy and our findings are not intended for hopeful treatments of pre-existing pathologies but rather to support the proposed healthy-cell bias therapeutic approach (Brinton 2005). Our preclinical pharmacology research work covers biochemistry, molecular biology and cell imaging of rodent brain. Controlled in vitro and in vivo studies are organized under four specific aims that test our hypotheses in brain tissues with a focus on the hippocampus and cortex ...
Gliobastoma multiforme (GBM) is an aggressive malignant form of brain tumour for which effective therapies are limited. Genetically engineered mouse models (GEMMs) harbouring mutations in components of the main signalling pathways that are altered in human GBM - including the receptor tyrosine kinase (RTK)-RAS- phosphoinositide-3-kinase (PI3K) pathway - are available. However, these GEMMs display a long latency to tumorigenesis and advanced tumour heterogeneity, which represents a challenge in preclinical drug testing. In this study, Zoë Weaver Ohler and colleagues developed an orthotopic and tractable mouse model of GBM by transplanting brain tumour cells derived from GBM-GEMMs into the brain (orthotopically) of syngeneic mice (non-transgenic wild-type mice with identical genetic backgrounds and intact immune systems). This model develops GBM with features of the human disease, including high vascularisation and aggressive invasion of surrounding tissues, and thus was used to test the effects ...

Object. Determining the efficacy of a drug used in experimental traumatic brain injury (TBI) requires the use of one or more outcome measures such as decreased mortality or fewer neurological and neuropsychological deficits. Unfortunately, outcomes in these test batteries have a fairly large variability, requiring relatively large sample sizes, and administration of the tests themselves is also very time consuming. The authors previously demonstrated that experimental TBI and human TBI induce mitochondrial dysfunction. Because mitochondrial dysfunction is easy to assess compared with neurobehavioral endpoints, it might prove useful as an outcome measure to establish therapeutic time windows and dose-response curves in preclinical drug testing. This idea was tested in a model of TBI in rats.. Methods. Animals treated with the selective N-type voltage-sensitive calcium channel blocker Ziconotide (also known as SNX-111 and CI-1009) after cortical impact displayed significant improvement in brain ...
