Tier III GS400133 • Transcriptome of the human dorsolateral prefrontal cortex of people with a history of cocaine use vs control (RNA-seq)


The total transcriptome including genes that are differentially expressed in cocaine addicts compared to control subjects. Post-mortem brain samples were collected from the dorsolateral prefrontal cortex (dlPFC) of the cocaine addict group and the control group. To assess gene expression, RNA-seq was performed. Data taken from Supplementary Table 2. Values presented are k.diff values. Data available from GEO with accession number GSE99349."

Gene Network Dysregulation in Dorsolateral Prefrontal Cortex Neurons of Humans with Cocaine Use Disorder.


Scientific reports 07 2017, Vol 7, pp. 5412


Metabolic and functional alterations of neurons in the dorsolateral prefrontal cortex (dlPFC) are thought to contribute to impulsivity, which is a hallmark of addictive behaviors that underlie compulsive drug seeking and taking in humans. To determine if there is a transcriptional signature in dlPFC neurons of humans with cocaine use disorder, we performed total RNA-sequencing on neuronal nuclei isolated from post-mortem dlPFC of cocaine addicts and healthy controls. Our results point toward a transcriptional mechanism whereby cocaine alters specific gene networks in dlPFC neurons. In particular, we identified an AP-1 regulated transcriptional network in dlPFC neurons associated with cocaine use disorder that contains several differentially expressed hub genes. Several of these hub genes are GWAS hits for traits that might involve dysfunction of brain reward circuitry (Body-Mass Index, Obesity) or dlPFC (Bipolar disorder, Schizophrenia). Further study is warranted to determine their potential pathophysiological role in cocaine addiction. PUBMED: 28710498
