Epigenetic processes have been implicated in the pathophysiology of alcohol dependence, but the specific molecular mechanisms mediating dependence-induced neuroadaptations remain largely unknown. Here, we found that a history of alcohol dependence persistently decreased the expression of Prdm2, a histone methyltransferase that monomethylates histone 3 at(More)
BACKGROUND Reward and energy homeostasis are both regulated by a network of hypothalamic neuropeptide systems. The melanin-concentrating hormone (MCH) and its MCH-1 receptor (MCH1-R) modulate alcohol intake, but it remains unknown to what extent this reflects actions on energy balance or reward. Here, we evaluated the MCH1-R in regulation of caloric intake(More)
Proinflammatory activity has been postulated to play a role in addictive processes and stress responses, but the underlying mechanisms remain largely unknown. Here, we examined the role of interleukin 1 (IL-1) and tumor necrosis factor-α (TNF-α) in regulation of voluntary alcohol consumption, alcohol reward and stress-induced drinking. Mice with a deletion(More)
Melanin-concentrating hormone (MCH) is involved in the regulation of food intake and has recently been associated with alcohol-related behaviors. Blockade of MCH-1 receptors (MCH1-Rs) attenuates operant alcohol self-administration and decreases cue-induced reinstatement, but the mechanism through which the MCH1-R influences these behaviors remains unknown.(More)
