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.

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.

Transcriptomic profiling of substantia nigra and putamen in Parkinson’s disease

Project description:We report RNA sequencing results of human substantia nigra and putamen samples from Parkinson's disease patients and controls. Each substantia nigra sample is the result of pooling brain tissue from two individuals with the same , while each putamen sample is the result of pooling brain tissue from three individuals. We found 354 differentially expressed genes (DEGs) in the SN of PD patients compared to age-matched controls, while we observed 261 DEGs in the putamen samples. The top-enriched pathways from the SN were associated with “protein folding” and “neurotransmitter transport”, and the putamen DEGs with “synapse organization”. In summary, our data confirms the key role of protein folding and neuronal degeneration in the pathology of PD, and highlights new genes and pathways that have not yet been explored in the context of PD.

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.

Histone H3 dopaminylation in ventral tegmental area underlies heroin-induced maladaptive plasticity

Project description:Persistent transcriptional events in ventral tegmental area (VTA) and other reward relevant brain regions contribute to enduring behavioral adaptations that characterize substance use disorder (SUD). Recent data from our laboratory indicate that aberrant accumulation of the newly discovered histone post-translational modification (PTM), H3 dopaminylation at glutamine 5 (H3Q5dop), contributes significantly to cocaine-seeking behavior following prolonged periods of abstinence. It remained unclear, however, whether this modification is important for relapse vulnerability in the context of other drugs of abuse, such as opioids. Here, we showed that H3Q5dop plays a critical role in heroin-mediated transcriptional plasticity in midbrain. In rats undergoing abstinence from heroin self-administration (SA), we found acute and persistent accumulation of H3Q5dop in VTA. By attenuating H3Q5dop during abstinence, we both altered gene expression programs associated with heroin withdrawal and reduced heroin-primed reinstatement behavior. These findings thus establish an essential role for H3Q5dop, and its downstream transcriptional consequences, in opioid-induced plasticity in VTA.
