Distinctive gene expression in brains of relapsing heroin-addicted rats

Thursday, August 6, 2009 - 22:14 in Biology & Nature

A group of genes whose expression is significantly altered following exposure to drug paraphernalia after an enforced 'cold-turkey' period have been identified. Researchers writing in the open access journal BMC Neuroscience studied gene expression in the brains of heroin-addicted rats, identifying those genes that may be involved in precipitating a relapse.
