Research focus
This article may help explain addiction science through research on opioid, cocaine, methamphetamine, dopamine. The source abstract begins by describing: “Substance use disorder (SUD) represents a substantial challenge in neuropsychiatric medicine, with the molecular mechanisms underlying its etiology remaining elusive.”
Key finding: Our findings highlight the significant role of circHomer1 in regulating cocaine reward and identify a novel molecular regulator of the actions of cocaine on the brain’s reward circuitry, providing a new strategy for treating drug addiction.
Why this may help: This may help explain why addiction can involve brain, behavior, mental health, craving, relapse, or treatment factors rather than simple willpower alone. It should be read as research information, not personal medical advice.
This article may help explain addiction science through research on opioid, cocaine, methamphetamine, dopamine. The source abstract begins by describing: “Methamphetamine (METH) is a widely abused psychostimulant, whose hyper-rewarding property is believed to underlie its addictive effect, but the molecular mechanism regulating this effect remains unclear.”
Key finding: Our findings demonstrate an important role for NAc novel-m009C in regulating METH reward, reveal a novel molecular regulator of the actions of METH on brain reward circuitries and provide a new strategy for treating METH addiction based on the modulation of small non-coding RNAs.

This article may help explain addiction science through research on cocaine, methamphetamine, dopamine, brain science. The source abstract begins by describing: “Converging evidence indicates that both dopamine and glutamate neurotransmission within the nucleus accumbens (NAc) play a role in psychostimulant self-administration and relapse in rodent models.”
Key finding: These findings indicate that in contrast to the well-recognized mesoaccumbal dopamine system that is critical to psychostimulant reward and relapse, there is a parallel mesoaccumbal glutamatergic system that suppresses reward and psychostimulant-seeking behavior.

This article may help explain addiction science through research on opioid, cocaine, dopamine, brain science. The source abstract begins by describing: “Persistent transcriptional events in ventral tegmental area (VTA) and other reward relevant brain regions contribute to enduring behavioral adaptations that characterize substance use disorder.”
Key finding: These findings establish an essential role for H3Q5dop, and its downstream transcriptional consequences, in heroin-induced functional plasticity in VTA.

This article may help explain addiction science through research on opioid, dopamine, brain science, withdrawal. The source abstract begins by describing: “The anterior cingulate cortex (ACC) is implicated in many pathologies, including depression, anxiety, substance-use disorders, and pain.”
Key finding: This commonality potentially suggests that the ACC is a locus for multiple withdrawal symptoms.

This article may help explain addiction science through research on opioid, alcohol, cocaine, methamphetamine. The source abstract begins by describing: “Substance use disorders (SUDs) are common and costly conditions that are partially attributable to genetic factors.”
Key finding: Overall, the findings highlight similarities and differences in immunogenetic profiles of SUDs that may influence the prevalence and co-occurrence of problematic SUDs and may contribute to assessment of SUD risk of an individual on the basis of their HLA genetic makeup.
