Expression data from human nucleus accumbens in heroin users and controls

Project description:The nucleus accumbens plays a central role in ther regulation of reward, emotion, motivation and goal-directed behavior. Gene expression impairments in this brain region are of crucial interest to understand the neurobiological underpinnings of heroin use disorder. We used the Affymetrix HG-U133A microarray to assess gene expression in the post-mortem nucleus accumbens of human heroin users and control subjects and identified differentially expressed genes.

MiR-218 regulates heroin seeking behavior by targeting Mecp2

Project description:Noncoding RNAs, especially microRNAs (miRNAs) have been implicated in the regulation of neuronal functions, such as learning, cognition and memory formation. However, the particular miRNAs involved in drug-induced behavioral plasticity are largely unknown. Here we report a novel regulator, miR-218, that inhibits heroin-induced behavioral plasticity. Network propagation-based method revealed several miRNAs that play key roles in drug-addiction, among which, miR-218 was decreased in nucleus accumbens (NAc) after chronic exposure to heroin. Lentiviral overexpression of miR-218 in NAc could inhibit heroin-induced reinforcement in both conditioning place preference (CPP) test and heroin self-administration (SA) experiment. Luciferase activity assay indicated miR-218 could regulate neuroplasticity related genes and directly target Mecp2 3’UTR. Consistently, Mecp2-/y mice exhibited reduced heroin seeking behavior in CPP test. These data reveal a functional role of miR-218 and its target, Mecp2, in the regulation of heroin-induced behavioral plasticity.

Epigenetic function during heroin self-administration controls future relapse-like behaviors in a cell type-specific manner

Project description:Opioid abuse produces enduring associations between the drug euphoria and features of the drug-taking experience, and these powerful associations can trigger relapse in individuals recovering from opioid use disorder. We show here that the epigenetic enzyme, histone deacetylase 5 (HDAC5), functions in the nucleus accumbens (NAc) during active heroin use to limit future relapse-like behavior. Moreover, enhancing HDAC5 function in NAc dramatically suppresses context-associated and reinstated heroin seeking behaviors, but it does not impact sucrose seeking. We also find that HDAC5 functions within dopamine D1 receptor-expressing medium spiny neurons (MSNs) to suppress cue-induced heroin seeking, but within dopamine D2 receptor-expressing MSNs to suppress drug-primed heroin seeking. Using cell type-specific transcriptomics analysis, we found that HDAC5 reduces expression of numerous genes linked to ion transport, and it decreases intrinsic excitability of NAc MSNs, suggesting that HDAC5 limits relapse vulnerability by suppressing NAc MSN firing rates during active heroin use. We used microarrays to define genes differentially expressed in the presence or absence of AAV2-DIO-HDAC5-3SA in both D1 and D2 cell-types derived from Nucleus accumbens following vTRAP.

Rat medial prefrontal cortex gene expression following heroin self-administration, abstinence, and extinction

Project description:Several studies have investigated changes induced by drug exposure, but few reports have described changes that persist following relapse. In the present study, genome-wide analysis of gene expression was conducted in rats that expressed behavioral incubation of heroin-seeking and goal-directed behavior. The medial prefrontal cortex (mPFC) is important in mediating goal-directed behavior and also was the target of this analysis. Rats were trained to self-administer heroin (0.06 mg/0.2 ml infusion) during 3 hour daily sessions for 14 days. Following the self-administration period, rats were reintroduced to the self-administration chambers for a 90-minute extinction session. The extinction session occurred either 1 day or 14 days following the final self-administration session. Behavioral data demonstrated incubation (increased expression) of heroin-seeking and goal-directed behavior after the 14 day abstinent period. Whole genome analysis was performed and selected results were confirmed by quantitative real-time PCR (RT-qPCR). Microarrays identified 66 genes whose expression was identified as changed by at least 1.4 fold (p<0.02) following 14 days of abstinence and the 90-minute extinction session, and seven of the genes on which RT-qPCR was performed were confirmed (BDNF, Calb1, Dusp5, Dusp6, EGR1, NPY, RGS2). Ontological analysis indicates that several of the genes with changed expression in this study are important for behavior and learning. The importance of drug-seeking behavior and memory of previous sessions of drug-taking suggest that such genes may be important for relapse. The global gene expression analysis adds to the knowledge of heroin-induced changes and further highlights similarities between heroin and other drugs of abuse. Keywords: heroin self-administration cRNA from 6 rats that self-administered heroin was compared to cRNA from 5 rats that received yoked infusions of saline.

Transcriptional effects of chronic heroin and methamphetamine treatment in the mouse striatum

Project description:To identify molecular effects of chronic drug treatment, heroin and methamphetamine treated animals were compared with saline treated animals at multiple time-points using microarray technology. Gene expression profile was assessed 14 h after the last dose of 1, 3, 6 or 12 days drug treatment and after 13, 15, 18 or 24 days of withdrawal. Animals were injected intraperitoneally with saline (SAL) (Polfa, Lublin, Poland), heroin (synthesized from morphine in Institute of Pharmacology PAS, Krakow, Poland) or D-methamphetamine (Sigma-Aldrich, Poznan, Poland) twice a day for consecutive 12 days in increasing doses. The Methamphetamine last dose (8 mg/kg) was four times greater than the first dose (2 mg/kg). It was also the case for heroin (40 and 10 mg/kg respectively). Mice were sacrificed by decapitation after 1, 3, 6 or 12 days of treatment or after 13, 15, 18 or 24 days of withdrawal.
