Following acquisition, reaction time and premature responses were analyzed with Hold Time (0.5, 1.0, 2.0 s) included as a within-subjects factor.
Are Genes to Blame for Criminals Who Commit Violent Crimes? There were no session genotype interactions, thus data were pooled across sessions to assess genotype effects. (h) Freezing (%) duration during presentation of the auditory cue and the original conditioning context following delay fear conditioning (n=910 per genotype). at Buffalo, Buffalo, NY, 3Dept. Accessibility J Neural Transm 2008; 115: 15731585. Those who possess both versions of these genes are 13 times more likely to commit particularly serious crimes, unlike those who do not have them. Cadherin-13, a risk gene for ADHD and comorbid disorders, impacts GABAergic function in hippocampus and cognition. These sex-specific factors may therefore amplify responding during reinstatement in females, producing ceiling effects that negate the predisposing properties of Cdh13 knock-out on reinstatement behavior. CDH13 is a member of the cadherin superfamily. To directly evaluate sex differences, we compared only wild-type males to wild-type females. the Psychiatry Advisor take: People who commit violent crime or engage in violent behavior may do so, in part, because of a variant in two genes, according to researchers.

Chen YJ, Zhang M, Yin DM, Wen L, Ting A, Wang P et al. In conclusion, our findings demonstrate that CDH13 localizes to the presynaptic compartment of hippocampal GABAergic synapses and safeguards the excitatoryinhibitory balance in the CA1 region. We assessed the effects of CDH13 deficiency on different behavioral domains. Cellular architecture of the mouse hippocampus: a quantitative aspect of chemically defined GABAergic neurons with stereology. This is the second study we look at from the 'Biology' section of 'Turning to Crime'. We found that our interaction between Port, Sex, and Genotype yielded a partial eta squared of .17, and thus a Cohens f of .45. However, unlike locomotor activation, there was no effect of Dose, and thus conditioning was similar at both the 10 mg/kg and 20 mg/kg doses (Fig. Le Strat Y, Ramoz N, Horwood J, Falissard B, Hassler C, Romo L, Choquet M, Fergusson D, Gorwood P. First positive reactions to cannabis constitute a priority risk factor for cannabis dependence. (a) Representative traces of miniature inhibitory postsynaptic currents (mIPSCs) recorded from CA1 pyramidal cells from acute brain slices from Cdh13+/+, Cdh13+/ and Cdh13/ mice. Child.

Willcutt EG, Doyle AE, Nigg JT, Faraone SV, Pennington BF . A large portion of the population has the so-called warrior gene (depending on race, around 40-50%). Locomotor data and side preference were analyzed using Topscan video tracking software (Clever Sys., Inc., Reston, VA; Flagel & Robinson, 2007, Meyer et al., 2012b). FASEB J 2007; 21: 30833095. A constitutive Cdh13 knockout mouse (Cdh13/) was generated through site-specific DNA recombination by crossing Cdh13loxP/loxP mice (C57Bl/6N background) with a constitutive Cre deleter line31 (Supplementary Figure S1 and Supplementary Table S1). Finally, no functional CDH13 variants associated with violent behavior have been identified yet and it is still unknown whether the nature of these variants results in a loss or a gain of CDH13 function.
The MAOA ("Warrior") Gene and Violence | IB Psychology Primary hippocampal neuron cultures were prepared from embryonic day 18 (E18) old rats as previously described32 and maintained in neurobasal media supplemented with B27, penicillin, streptomycin and l-glutamine (GIBCO-Invitrogen, Darmstadt, Germany). Drgon T, Montoya I, Johnson C, Liu QR, Walther D, Hamer D, Uhl GR. 1c, 1d). For the cue-induced reinstatement test, only the first 10 minutes, during which peak responding occurs, were analyzed. We ran a planned comparison between wild-type and knock-out for the post-test time spent on the methamphetamine-paired floor. The rodent Cdh13 knock-out model may therefore prove useful in future studies targeting direct biological mechanisms of Cdh13 on behavior. The contribution of GABAergic dysfunction to neurodevelopmental disorders. Genet. During intravenous self-administration of addictive compounds, the progressive-ratio procedure can be used to determine the motivational strength of a drug reinforcer by requiring subjects to continually increase operant responding (Richardson & Roberts, 1996). The https:// ensures that you are connecting to the S2a). RhoA and Rac mediate endothelial cell polarization and detachment induced by T-cadherin. of Immunology, Janssen R&D, Spring House, PA, 4Dept.

Anyway, the authors were especially interested in the most violent offenders, defined in this study as having committed more than 10 seriously violent crimes. (c) Immunofluorescence staining of cultured hippocampal neurons for CDH13 (green) and GABA-A receptor 1 subunit (GABA-A1, red). The prevalence of violence in our society has motivated biomedical researchers, sociologists and psychologists to look for genetic markers, predictors and causes for this destructive human behavior. To guarantee cellular and regional specification of synaptic contacts, the formation of neuronal networks is tightly controlled by a myriad of cell guidance and adhesion molecules, among which the cadherin superfamily of calcium-dependent cell adhesion molecules is of particular relevance.1 Furthermore, after development, cadherins regulate the function and plasticity of mature synapses by participating in synaptic vesicle dynamics or controlling the stability of synaptic receptors.1. Genome-wide association studies in humans have suggested that variants of the cadherin-13 (CDH13) gene are associated with substance use disorder, subjective response to amphetamine, and attention deficit hyperactivity disorder. American journal of medical genetics. PubMed 2010; and Steckler et al. Genes, many argue is the answer to understanding the mind of a serial killer and the only was to stop these murders is to detect these genetic defects early in their childhood. Ongur D, Prescot AP, McCarthy J, Cohen BM, Renshaw PF . Neuron 2011; 70: 863885. KCNJ6 variants modulate reward-related brain processes and impact executive functions in attention-deficit/hyperactivity disorder. The aim of this study was to identify potential epigenetic prognostic biomarkers for colorectal cancer (CRC) in the Chinese population. On the motivational properties of reward cues: Individual differences. Uhl GR, Drgon T, Liu QR, Johnson C, Walther D, Komiyama T et al. The conditioning procedure increased the amount of time spent on the drug-paired floor [main effect of Test: (F (1, 97) = 150.62, p < 0.001)]. Separate subjects underwent conditioned cue preference (ages 76101 d), to either a 10 mg/kg (n = 33; 515 / and +/+, 13 +/) or 20mg/kg dose of cocaine (n = 38; 1415 +/+ and /, 9 +/) (Table S1a). The present findings therefore contribute to the understanding of how dysregulation of CDH13 function may predispose individuals to ADHD and related comorbidities. A preliminary analysis revealed that the statistical power of our experimental setups to detect genotype-dependent differences with a medium effect size was of at least 0.8. Genome-wide association study of comorbid depressive syndrome and alcohol dependence. The methylation status of 10 genes was determined in 98 surgically resected bladder cancers, and we calculated the median methylation index (MI), a reflection of the methylated fraction of the genes tested. The assessment of hippocampus-dependent visuospatial memory in the Barnes maze showed that all mice learned to find the hidden escape box in both acquisition and reversal, as indicated by gradually decreasing distances, escape latencies and primary errors throughout the successive trials (significant session effects: all P<0.001; data not shown). Rats were housed on a 12h reverse light/dark cycle (lights off at 07300800h), and all testing occurred during the dark phase at least 1 hour following lights off. This site needs JavaScript to work properly. During acquisition, number of completed trials was analyzed using repeated-measures ANOVA with Session block (15, 610, 1115, 1620, 2125) as the within-subjects factor, and Genotype (WT, KO) as the between-subjects variable. Rapid synthesis of the X-linked mental retardation protein OPHN1 mediates mGluR-dependent LTD through interaction with the endocytic machinery. For example, the increased number of timeout responses during the training session may also support the notion of cognitive inflexibility in these mice.76 By contrast, during the 5-CSRTT, no modifications in attention or impulsivity were detected in Cdh13/ mice. Hinney A, Scherag A, Jarick I, Albayrak , Ptter C, Pechlivanis S, Dauvermann MR, Beck S, Weber H, Scherag S, Nguyen TT, Volckmar AL, Knoll N, Faraone SV, Neale BM, Franke B, Cichon S, Hoffmann P, Nthen MM, Schreiber S, Jckel KH, Wichmann HE, Freitag C, Lempp T, Meyer J, Gilsbach S, Herpertz-Dahlmann B, Sinzig J, Lehmkuhl G, Renner TJ, Warnke A, Romanos M, Lesch KP, Reif A, Schimmelmann BG, Hebebrand J Psychiatric G.C.A.s. The hippocampus is central to cognition, spatial navigation, as well as memory formation and specifically the regulation of emotional memories.35 Furthermore, altered verbal and visuospatial working memory is one of the neurocognitive alterations widely described in ADHD.70, 71, 72 Other mouse models for neurodevelopmental disorders, such as Down syndrome or neurofibromatosis type 1, also present increased inhibition, which correlates with spatial memory deficits.42, 73, 74, 75 Remarkably, the excitation/inhibition imbalance triggered by the loss of CDH13 function in the hippocampus was consistently reflected in the behavior of CDH13-deficient mice. Hippocampal CA1 neurons from Cdh13 null mutant mice show increased inhibitory synaptic input and morphological changes. CDH13 is expressed throughout the adult brain (Takeuchi et al., 2000), where it is thought to act as a negative regulator of neural proliferation, including regions known to be involved in drug abuse and behavioral regulation such as cortex and midbrain. ErbB4 regulation of a thalamic reticular nucleus circuit for sensory selection. Vogels TP, Abbott LF . Here, we focused on the hippocampus to test in vivo the hypothesis that involvement of CDH13 in the susceptibility to neurodevelopmental/psychiatric disorders is associated with its potential role in the modulation of synaptic function. Conditioned place preference: what does it add to our preclinical understanding of drug reward? Intrinsic electrophysiological properties, such as membrane potential, input resistance and action potential properties, were identical between Cdh13+/+ and Cdh13/ animals (Supplementary Table S3). Conditioned place preference traditionally measures approach and avoidance to a Pavlovian drug-paired context, and is thought to reflect rewarding and aversive properties of drugs (Bardo & Bevins, 2000). Mechanism for the learning deficits in a mouse model of neurofibromatosis type 1. Anyway, the authors were especially interested in the most violent offenders, defined in this study as having committed more than 10 seriously violent crimes. Mavroconstanti T, Halmoy A, Haavik J . Genes Brain Behav. Google Scholar. Fiederling A, Ewert R, Andreyeva A, Jungling K, Gottmann K . Usually, an odds ratio of more than 2 makes you sit up and take notice that a finding could be something very interesting. During early drug exposure, these responses may be pivotal in promoting future intake. IMpACT unites major research centers working on the genetics of ADHD persistence across the lifespan and has participants in the Netherlands, Germany, Spain, Norway, the United Kingdom, the United States, Brazil and Sweden. One possibility is that the pathway from Cdh13 function to behavior in females is similar to males, but for a variety of reasons was masked by factors that can influence drug sensitivity such as circulating hormone status (Becker, 1999) or sex differences in the organization of the central nervous system during development (Hu et al., 2004). S4, S5). We therefore suggest that future studies on this topic may benefit from using approaches that more directly ascertain reward-directed motivation by introducing instrumental contingencies.

Meyer PJ, Lovic V, Saunders BT, Yager LM, Flagel SB, Morrow JD, Robinson TE. In a separate analysis by the CDH13 genotype, the HR for all-cause mortality was linearly increased with the number of G alleles (P value for HMWA-CDH13 genotype interaction = 0.023). Subjects self-administered cocaine on a progressive ratio schedule of reinforcement, in which the requirement for each successive infusion of cocaine increased within session (c, d). Following progressive ratio, subjects were returned to an FR1 schedule of reinforcement and allowed to self-administer up to 40 infusions of 0.2 mg/kg cocaine [main effect of Port: (F (1,43) = 6.1, p < 0.05)] (Fig. The within-subjects factors across conditioning days were Trial (14) and Drug (saline, cocaine).

Cell Signal 2009; 21: 10351044. Together, these data indicate that CDH13 is a negative regulator of inhibitory synapse function. Although there was a main effect of session in responding for cocaine, all genotypes and sexes increased rate of responding for cocaine similarly (a, b). In contrast to saccharin, we found that wild-type and knock-out subjects showed similar responses for water. A red houselight was located on the rear panel of the chamber (27cm high).

Subjects were analyzed for time spent on the drug-paired side of the conditioning apparatus using a repeated-measures ANOVA, with Test day as the within-subjects factor (Day 1, Day 8) and Genotype as the between-subjects factor (WT, KO). Rats were injected with cocaine (either 10 mg/kg, i.p. However, the effect sizes presented here when taken together suggest that behavioral paradigms that exploit operant conditioning (e.g. Importantly, it provides a second mechanism though which differences in Cdh13 function might alter behavior. Saunders BT, Robinson TE. Our electrophysiological findings support the view that CDH13 may act as a synapse destabilizer. Data are presented as means SEM, and are collapsed across sex. We found that, compared to saline, cocaine injections produced robust increases in locomotor activity at 10 mg/kg [main effect of Drug (F (1,63) = 66.55, p < .001)] (Fig. Reconstructions were analyzed in NeuroExplorer (MBF Bioscience) for intrinsic parameters and Sholl analysis. 5b).

Cdh13 and AdipoQ gene knockout alter - Wiley Online Library Biological Theories of Crime: Explanation, Pros & Cons - StudySmarter US The alteration in cognitive functions observed in Cdh13-deficient mice are in general mild but not unexpected, given the observation that single genetic risk variants for neuropsychiatric disorders tend to display very modest effect sizes.77 Moreover, considering that deficits and impairments associated with neurodevelopmental disorders, such as ADHD, are more poorly compensated during childhood, the effects of CDH13 deficiency on mouse behavior might even be more pronounced in adolescent mice compared with adult animals investigated in our study. Careers. S4, S5, see supporting information). Heterozygotes were excluded from analysis. Rivero O, Sich S, Popp S, Schmitt A, Franke B, Lesch KP . Also in contrast to methamphetamine conditioning, the only effect of genotype was a four-way interaction [Test Sex Genotype Dose interaction: (F (3, 97) = 3.08, p < 0.05)], however, post-hoc analysis indicated that there were no genotype effects within dose and sex as a result of this interaction. Sullivan PF, Daly MJ, ODonovan M. Genetic architectures of psychiatric disorders: the emerging picture and its implications. The 0.5 mg/kg/infusion dose was produced by increasing the length of the infusion rather than by modifying the concentration of cocaine given. Sex differences in vulnerability to drug self-administration. Nat Protoc 2012; 7: 394407. Individual test sessions lasted 18 minutes with a 1-hour interval between the start of each test. For locomotor activity analysis, the between-subjects factors were Genotype (WT, HET, KO), Sex (male, female), and Dose (10 mg/kg, 20 mg/kg). All other features of the testing environment were identical to sessions 110. The effects of smoking and obesity is related to a genetic variant in the CDH13 gene . The results showed that . We also compared the responses of these two genotypes when working for a water reinforcer, with the hypothesis that there would be no difference when the fluid was a non-reward. Hippocampus. For preference analysis, we examined time spent on the cocaine paired side using the between-subjects factors: genotype (WT, Het, KO), sex (male, female), and drug dose (10 mg/kg, 20 mg/kg). Molecular genetics of addiction and related heritable phenotypes: genome-wide association approaches identify connectivity constellation and drug target genes with pleiotropic effects.

This locomotor activation was larger in the subjects who underwent conditioning to the 20 mg/kg dose [Dose Drug interaction (F (1, 63) = 5.63, p < 0.05)] (Fig. Cdh13 / rats showed higher responding for a saccharin reinforcer and learned the choice reaction time task more slowly than wild-types. Genome-wide association study of bipolar disorder in Canadian and UK populations corroborates disease loci including SYNE1 and CSMD1. Figuring out the physiology and phenotype defined by the genotype is certainly interesting, but it's way too early to start planning a kids career based on her results from 23andMe. Liu QR, Drgon T, Johnson C, Walther D, Hess J, Uhl GR. Offenders who had committed 10 or more serious violent crimes were significantly more like to carry one of several loss-of-function variants in the MAOA gene (odds ratio 2.66, 95% CI 1.60-4.42) or . Each half of the open field was separated by a 30cm tall black divider, which contained a 5cm 5cm entryway between each side.

Mol Psychiatry; e-pub ahead of print 2 December 2014; doi: 10.1038/mp.2014.156. However, during reversal, where the escape box is located in a different position, Cdh13/ mice made significantly more primary errors than Cdh13+/+ mice (P=0.027), indicating impaired cognitive flexibility. The authors declare no conflict of interest. Three of the 4 cell lines that lost expression showed a deletion of the CDH13 locus accompanied by hypermethylation of the remaining allele.

The role of cadherins in synapse (de)stabilization and plasticity has been well documented.1, 65, 66 The mechanism whereby CDH13 would participate in synapse (de)stabilization might involve heterophilic interactions in trans with elements of the postsynaptic compartment and/or also interactions in cis with presynaptic transmembrane molecules in close proximity. However, there were no significant effects or interactions with either Genotype or Sex on responding throughout acquisition of self-administration (Fig. Tiihonen J, Rautiainen MR, Ollila HM, Repo-Tiihonen E, Virkkunen M, Palotie A, Pietilainen O, Kristiansson K, Joukamaa M, Lauerma H, Saarela J, Tyni S, Vartiainen H, Paananen J, Goldman D, Paunio T. Genetic background of extreme violent behavior. Despite this finding, no AdipoQ knock-out effect was observed when conditioning using d-amphetamine across a range of doses from 0.5 to 4 mg/kg.
The genetics of violent behavior - The Jackson Laboratory For significant genotype effects or interactions, we tested planned comparison between wild-type and knock-out subjects, hypothesizing that knock-out subjects would show more responses for a palatable saccharin reward compared to wild-type subjects. No significant genotype effects on any variable measured in the 5-CSRTT were detected. Both sides of the compartment were distinguished with separate visual and tactile stimuli. The tendency to sign-track predicts cue-induced reinstatement during nicotine self-administration, and is enhanced by nicotine but not ethanol. Decreased serum levels of adiponectin in adult attention deficit hyperactivity disorder. Together with our finding that CDH13 is expressed in inhibitory neurons in the SO, these data provide evidence that, in hippocampal neurons, CDH13 localizes at the presynaptic compartment of inhibitory synapses. S1b, S1c). Hippocampal long-term potentiation suppressed by increased inhibition in the Ts65Dn mouse, a genetic model of Down syndrome. Thank you for visiting nature.com. All procedures were approved by the University at Buffalos Institutional Animal Care and Use Committee. Separate AdipoQ knock-out and wild-type mice were also conditioned to one of four doses of d-amphetamine using an identical procedure. A violation of homogeneity of variance was established when the result of this test yielded p < 0.05. Traces were recorded using a Multiclamp 700B amplifier (Molecular Devices, Wokingham, UK). Other traces were analyzed using Clampfit 10.2. There were no effects or interactions with genotype following progressive ratio (p > 0.05).
