DNA methylation analysis of methamphetamine abusers with different addiction susceptibility

ABSTRACT: Genome wide DNA methylation profiling of normal and methamphetamine (MA) abusers with different addiction susceptibility. The Illumina Infinium HumanMethylation450 Beadchip was used to obtain DNA methylation profiles in peripheral blood lymphocytes (PBLs). Samples included 8 health controls, 8 high MA addiction susceptibility (HMAS) abusers, and 8 high MA addiction susceptibility (LMAS) abusers.

Protective Role for the Disulfide Isomerase PDIA3 in Methamphetamine Neurotoxicity

Project description:Methamphetamine abuse continues to be a worldwide problem, damaging the individual user as well as society. Only minimal information exists on molecular changes in the brain that result from methamphetamine administered in patterns typical of human abusers. In order to investigate such changes, we examined the effect of methamphetamine on the transcriptional profile in brains of monkeys. Gene expression profiling of the caudate and hippocampus identified protein disulfide isomerase family member A3 (PDIA3) to be significantly up-regulated in the animals treated with methamphetamine as compared to saline treated control monkeys. Treatment of primary rat neurons with methamphetamine revealed an up-regulation of PDIA3, showing a direct effect of methamphetamine on neurons to increase PDIA3. In vitro studies using a neuroblastoma cell line demonstrated that PDIA3 expression protects against methamphetamine-induced cell toxicity and methamphetamine-induced intracellular reactive oxygen species production, revealing a neuroprotective role for PDIA3. The current study implicates PDIA3 to be an important cellular neuroprotective mechanism against a toxic drug, and as a potential target for therapeutic investigations.

Gene expression following acute methamphetamine administration in selectively bred mice

Project description:This study examined NAc gene expression in a pair short-term selected lines bred for high or low response to methamphetamine (MA). We sought to identify candidate genes preferentially expressed among individuals showing either large or small acute responses to MA. Additionally, we sought to identify genes and networks differentially expressed by MA exposure within these divergent lines. Keywords: Short-term selected lines (STSLs), saline (SAL), methamphetamine (MA), nucleus acumbens (NAc)

Transcription profiling by high throughput sequencing of methamphetamine-sensitized and saline-control mouse nucleus accumbens

Project description:Using ssRNA-seq, we examined the alteration of transcription profiles in the nucleus accumbens of methamphetamine-sensitized mice. Methamphetamine was a commonly abused psychostimulant. Repeated exposure to methamphetamine elicited long-lasting cellular and molecular changes, including the aberrant expression of coding and non-coding RNAs, which may involve in methamphetamine-induced locomotor sensitization and addiction.

Regional Analysis of The Brain Transcriptome In Mice Bred For High And Low Methamphetamine Consumption

Project description:Transcriptome profiling can broadly characterize drug effects and risk for addiction in the absence of drug exposure. Modern large-scale molecular methods, including RNA-sequencing (RNA-Seq), have been extensively applied to alcohol-related disease traits, but rarely to risk for methamphetamine (MA) addiction. We used RNA-Seq data from selectively bred mice with high or low risk for voluntary MA intake to construct coexpression and cosplicing networks for differential risk. Three brain reward circuitry regions, the nucleus accumbens (NAc), prefrontal cortex (PFC) and ventral midbrain (VMB), were explored. With respect to differential gene expression and wiring, the VMB was more strongly affected than either the PFC or NAc. Coexpression network connectivity was higher in the low line than the high line in the VMB, oppositely affected in the NAc, and little impacted in the PFC. Gene modules protected from the effects of selection may help to eliminate certain mechanisms from significant involvement in risk for MA intake. One such module was enriched in genes with dopamine-associated annotations. Overall, the data suggest that mitochondrial function and glutamate-mediated synaptic plasticity have key roles in the outcomes of selective breeding for high versus low levels of MA intake.

Transcription profiling of mouse after acute methamphetamine administration in selectively strains

Project description:This study examined NAc gene expression in a pair short-term selected lines bred for high or low response to methamphetamine (MA). We sought to identify candidate genes preferentially expressed among individuals showing either large or small acute responses to MA. Additionally, we sought to identify genes and networks differentially expressed by MA exposure within these divergent lines. Experiment Overall Design: STSLs generated from C57BL/6J x DBA/2J stock were bred for high (HMACT) or low (LMACT) acute MA response. Mice were given a challenge injection of MA or SAL, and decapitated 1 hr later. NAc gene expression was assessed.

Transcriptional profiling reveals differential changes in the respective expression of oxytocin and CART mRNA levels in the nucleus accumbens and dorsal striatum of compulsive methamphetamine taking rats (nucleus accumbens)

Project description:Methamphetamine addiction is mimicked in rats that self-administer the drug and accelerate their intake when given long access to it. Self-administration (SA) models do not include adverse consequences that are necessary to reach a diagnosis of addiction in humans. Here, we studied transcriptional consequences of methamphetamine SA and repeated foot-shocks in rat brain.
