This represents the next generation of nucleic acid microarrays, which will aid in the characterization of nucleic acids, studying the ageing process and improving the drug discovery process. A–T, G–C, to subsequently bind their complementary ‘targets’. PALB5270. Microarrays allow researchers to gain an unprecedented understanding of the function and regulation of genes, and are transforming virtually all areas of biological research. Microarrays provide a new high throughput avenue to enable large-scale analysis of messenger RNA abundance as an indicator of gene expression (cDNA arrays), to detect polymorphisms or mutations within a population using single nucleotide polymorphisms (SNP arrays), and to look for genomic gains and losses, or copy number changes of a particular gene involved in a disease (CGH arrays). These `genome chips' will provide unprecedented access to key areas of human health, including disease prognosis and diagnosis, drug discovery, toxicology, aging, and mental illness. Pharmaceutical companies have adopted high-data-capacity microarrays in drug discovery research for applications such as target identification, target validation and pathway analysis, compound profiling, and toxicology studies. This is accomplished using relevant animal models and validated procedures. 37 Mycobacteriology/TB Program. Among the latest waves of data beginning to wash over the drug-discovery enterprise is that deriving from genetic markers in the human genome. Microarrays have applications in the entire drug discovery pipeline to improve selection of biological targets and lead compounds. labeled nucleic acid sam ples ...

Tang, MD, PhD, FRCPCClinical Assistant ProfessorDept Path Lab MedicineUniversity of British Columbia Email patrick.tang_at_bccdc.ca. Drug discovery and development 1. Microarrays 87 3.05.1 ... target identification in the drug discovery process. Curr Opin Drug Discov Devel 5, 690-700. Presented By D Associate Professor Department of Pharmaceutics KLE University BELGAUM – 590010 2. Advances in non-invasive in vivo imaging techniques have raised the use of animal models in drug discovery and development to a new level by enabling quick and efficient drug screening and evaluation. This represents the next generation of nucleic acid microarrays, which will aid in the characterization of nucleic acids, studying the ageing process and improving the drug discovery process. Microarrays containing sequences representative of all human genes may soon permit the expression analysis of the entire human genome in a single reaction. Clipping is a handy way to collect important slides you want to go back to later. The “new” biology The most challenging task for a scientist is to make sense of lots of data 4. ROLE OF BIOINFORMATICS, ... one of the most important steps is the determination of three dimensional structure of a target protein or nucleic acid. The technique has immense potential and promises to play a key role in furthering research in a number of fields, as discussed in this chapter. This technology has revolutionized drug discovery and development, as well. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

The Drug Discovery Process ... blockade of histamine H2 receptor-induced acid secretion suggests a reductionist system involving antagonism of his- ... ides, lipids, and nucleic acids. The microarrays also allow for characterization of their structure under different environmental conditions. sive bioinformatic analyses, including assembly into contigs, and nucleic acid and protein homology searches. West Bellfort Street Suite 270 Houston, TX 77054 USA Local (713) 664-7087 Toll Free: 1-888-528-8818 Fax: (713) 664-8181 www.lcsciences.com About Us LC Sciences is a global biotechnology company providing products and services to genomics and proteomics researchers across an array of markets for nucleic acid/protein analysis, biomarker-discovery and drug development. acids, nucleic acid-ligand binding, drug binding, probe-target reactions, and nucleic acid hybridization routines are discussed in the context of nucleic acid-based therapeutics and some DNA delivery systems. RNASeq - Analysis Pipeline for Differential Expression. It also features the ability to be manufactured easily at moderate sized molecules and the potential to exhibit efficacy and safety that surpasses those of antibody medicines. Nucleic acids are another class of important drug targets. The challenge for drug discovery scientists is to iden- NAT has been associated with blood screening for some time. Nucleic acid microarrays (genome chips) are generated by arraying nucleotide ‘probes’ onto a support matrix, and utilize the principle of specific base pairing, i.e. The liver plays a central role in metabolism; ... hepatocytes and those in model organisms create challenges in establishing functional test beds to detect the potential drug toxicity and efficacy of … - Over/underexpressed genes in the diseased cells can suggest drug targets Pharmacology and Toxicology - Highly sensitive indicator of a drug’s activity (pharmacology) Just like proteins, nucleic acids are polymeric macromolecules. Drug discovery Applicable in pharmacogenomics Comparative analysis of gene Help the identification of specific proteins produce by diseased cells.
