    Abstract Pharmacogenetics, the inherited basis for interindividual differences in drug response, has rapidly expanded with the advent of new molecular tools and the sequencing of the human genome, yielding pharmacogenomics. We review here recent ideas and findings regarding pharmacogenomics of components of the autonomic nervous system, in particular, neuronal nicotinic acetylcholine receptors, postsynaptic receptors with which the parasympathetic and sympathetic neurotransmitters, acetylcholine (ACh) and norepinephrine, respectively, interact. The receptor subtypes that mediate these responses, M(1-3) muscarinic cholinergic receptors (mAChRs), and alpha(1A,B,D)-, alpha(2A,B,C)-, and beta(1,2,3)-adrenergic receptors (AR), show highly variable expression of genetic variants; variants of mAChRs and alpha(1)-ARs are relatively rare, whereas alpha(2)-AR and beta-AR subtype variants are quite common. The largest amount of data is available regarding variants of the latter ARs and represents efforts to associate certain receptor genotypes, most commonly, single nucleotide polymorphisms, with particular phenotypes (e.g., cardiovascular and metabolic responses). In vitro and in vivo studies have yielded inconsistent results; definitive conclusions are limited. We identify several conceptual and methodological problems with available data: sample size, ethnicity, tissue differences, coding versus noncoding variants, limited studies of haplotypes, and interaction among variants. Thus, although progress has been made in identifying genetic variation that influences drug response fo autonomic nervous system components, we are still at the early stages of defining the most critical genetic determinants and their role in human physiology and pharmacology.

    Abstract We describe a cell-based kinetic profiling approach using impedance readout for monitoring the effect of small molecule compounds. This noninvasive readout allows continuous sampling of cellular responses to biologically active compounds and the ensuing kinetic profile provides information regarding the temporal interaction of compounds with cells. The utility of this approach was tested by screening a library containing FDA approved drugs, experimental compounds, and nature compounds. Compounds with similar activity produced similar impedance-based time-dependent cell response profiles (TCRPs). The compounds were clustered based on TCRP similarity. We identified novel mechanisms for existing drugs, confirmed previously reported calcium modulating activity for COX-2 inhibitor celecoxib, and identified an additional mechanism for the experimental compound monastrol. We also identified and characterized a new antimitotic agent. Our findings indicate that the TCRP approach provides predictive mechanistic information for small molecule compounds.

    Abstract Several recent studies report an association between trace amine-associated receptor 6 (TAAR6) and susceptibility to schizophrenia and bipolar affective disorder in humans. However, endogenous TAAR6 agonists and the receptor signaling profile and brain distribution remain unclear. Here, we clone TAAR6 from the rhesus monkey and use transfected cells to investigate whether this receptor interacts with brain monoamines and a psychostimulant drug to trigger cAMP signaling or extracellular signal-regulated kinase (ERK) phosphorylation, while investigating its expression profile in the rhesus monkey brain. Unlike TAAR1, rhesus monkey TAAR6 did not alter cAMP levels in response to 10 microM of monoamines (dopamine, norepinephrine, serotonin, beta-phenylethylamine (beta-PEA), octopamine, tryptamine, and tyramine) or methamphetamine in stably transfected cells in vitro. Real-time cell electronic sensing analysis indicated that the receptor did not alter cell impedance or change the effect of forskolin on cell impedance at exposure to 20 microM of each monoamine, suggesting a lack of either Gs or Gi-linked signaling. Whereas kappa opioid receptor activation led to ERK phosphorylation at exposure to 1 microM U69593, rhesus monkey TAAR6 had no such effect at exposure to 10 microM of monoamines or methamphetamine. Membrane and cell surface localization of TAAR6 was confirmed by immunocytochemistry, biotinylation, and Western blot testing with a TAAR6 antibody in the transfected cells. Real-time reverse transcriptase-polymerase chain reaction amplification showed that TAAR6 mRNA was undetectable in selected rhesus monkey brain regions. Together, the data reveal that TAAR6 is unresponsive to brain monoamines and is not expressed in rhesus monkey brain monoaminergic nuclei, suggesting TAAR6 lacks direct association with brain monoaminergic neuronal function.

    Abstract Cell-based assays have become an integral part of the preclinical drug development process. Recently, noninvasive label-free cell-based assay technologies have taken center stage, offering important and distinct advantages over and in addition to traditional label-based endpoint assays. Dynamic monitoring of live cells, the preclusion of label, and kinetics are some of the fundamental features of cell-based label-free technologies. In this article we will discuss the real-time cell electronic sensing (RT-CES, ACEA Biosciences Inc., San Diego, CA) system and some of its key applications for cell-based assays such as cell proliferation and cytotoxicity, functional assays for receptor-ligand analysis, cell adhesion and spreading assays, dynamic monitoring of endothelial barrier function, and dynamic monitoring of cell migration and invasion. Also, where appropriate we will briefly discuss other label-free technologies in an application-specific manner.

    Abstract In this paper we have explored the utility of the real-time cell electronic sensing (RTCES, ACEA Biosciences Inc., San Diego, CA) system for monitoring the quality of live cells in cell-based assays as well as for assay development. We have demonstrated that each cell type displays unique growth kinetic profiles that provide a quantitative account of cell behavior and can be used as a diagnostic tool for cellular quality control. The utility of the specific signature patterns was shown by demonstrating the significant differences in primary cell behavior depending on the supplier. In addition, the RT-CES system was able to differentiate cell behavior depending on the passage stage of the cells. The utility of the RT-CES system as an assay development tool was demonstrated in cytotoxicity assays. The RT-CES system not only provides information regarding the potency of cytotoxic compounds, but in addition relates potency to the rate of the response for each concentration of the compound tested, which is important for understanding the mechanism of compound action. Moreover, real-time display of cytotoxicity data by the RT-CES system allows for calculation of real-time 50% inhibitory concentration (IC50) values or determination of optimal IC(50) value. In summary, the RT-CES system provides high content and information-rich data that are beyond the scope of single-point assays.

    Abstract The intestinal epithelium is dynamic, with proliferation of undifferentiated crypt cells balanced by terminal differentiation and cell death at the colon surface or small intestinal villus tips. Cyclic AMP, induced by agonists such as prostaglandin E(2) and vasoactive intestinal polypeptide, promotes proliferation and ion secretion and suppresses apoptosis in intestinal epithelial cells. Here, we show that cell differentiation in a model intestinal epithelium leads to attenuation of cAMP production in response to G protein-coupled receptor and receptor-independent agonists. Concomitantly, key components of the cAMP cascade, the alpha subunit of the stimulatory G protein, G(s), and adenylyl cyclase (AC) isoforms 3, 4, 6, and 7 are down-regulated. By contrast, AC1, AC2, AC8, and AC9, and the receptors for prostaglandin E(2) and vasoactive intestinal polypeptide, are not expressed or not affected by differentiation. We confirmed key findings in normal murine colon epithelium, in which the major AC isoforms and G(s)alpha are markedly down-regulated in differentiated surface cells. Suppression of AC isoforms and G(s)alpha is functionally important, because their constitutive expression completely reverses differentiation-induced cAMP attenuation. Thus, down-regulation of AC isoforms and G(s)alpha is an integral part of the intestinal epithelial differentiation program, perhaps serving to release cells from cAMP-promoted anti-apoptosis as a prerequisite for cell death upon terminal differentiation.

    Abstract In previous work, we identified genetic correlations between cAMP accumulation in the cerebellum and sensitivity to the incoordinating effects of ethanol. A genetic correlation suggests that common genes underlie the phenotypes investigated. One method for provisionally identifying genes involved in a given phenotypic measure is quantitative trait locus (QTL) analysis. Using a panel of 30 BXD recombinant inbred strains of mice and the progenitors (DBA/2J and C57BL/6J), and the dowel test for ataxia, we measured the blood ethanol concentrations at the time an animal first fell from the dowel and acute functional tolerance (AFT), and investigated cAMP signaling in the cerebellum. Cyclic AMP accumulation was measured in whole-cell preparations of cerebellar minces from individual mice under basal or stimulated conditions. We conducted a genome-wide QTL analysis of the behavioral and biochemical measures with >2000 genetic markers to identify significant associations. Western blot and comparative sequencing analysis were used to compare cAMP response element binding protein (CREB) levels and protein-coding sequence, respectively. QTL analyses correlating strain means with allelic status at genetic markers identified several significant associations (p < 0.01). Analysis of variance revealed an effect of strain on behavioral and biochemical measures. There was a significant genetic correlation between initial sensitivity and basal cAMP accumulation in the cerebellum. We identified 6 provisional QTLs for initial sensitivity on four chromosomes, 6 provisional QTLs for AFT on four chromosomes, and 11 provisional QTLs for cAMP signaling on nine chromosomes. Two loci were found to overlap for measures of initial sensitivity and for cAMP signaling. Given the genetic correlation between initial sensitivity and basal cAMP accumulation, we investigated candidate genes in a QTL on chromosome 1. Comparative sequence analysis was performed, and protein levels were compared between C57 and DBA mice for Creb1. No significant differences were detected in coding sequence or protein levels for CREB. These results suggest that although ethanol sensitivity and cAMP signaling are determined by multiple genes, they may share certain genetic codetermination.

    Abstract Background: In humans, adolescent exposure to alcohol is associated with the onset of adult alcohol dependency and suggests that early use potentiates vulnerability to addiction. The aim of the present study was to address whether chronic ethanol exposure during adolescence would alter nucleus accumbens septi (NAcc) dopamine (DA) levels in the adult brain.
    Methods: Rats were injected daily from postnatal day (PND) 30 to 50 with either 0.75 g/kg/i.p. ethanol or saline followed by an ethanol-abstinent period from PND 51 to 65. Changes in extracellular DA levels in the anterior NAcc shell were measured via the no net flux (NNF) paradigm.
    Results: Extracellular DA levels were greater in rats chronically treated with ethanol during adolescence (6.5 nM DA) in comparison with saline-exposed controls (3.6 nM DA). There were no differences in extraction fraction (E(d)), an indirect measure of DA reuptake, between ethanol-treated (87%) and nontreated (68%) rats.
    Conclusions: Together these findings suggest that changes in extracellular DA may be an underlying physiological mechanism in adolescent vulnerability to the rewarding properties of ethanol.
