| abstractText | Expression of the downstream regulatory element antagonist modulator (DREAM) protein in dorsal root ganglia and spinal cord is related to endogenous control mechanisms of acute and chronic pain. In primary sensory trigeminal neurons, high levels of endogenous DREAM protein are preferentially localized in the nucleus, suggesting a major transcriptional role. Here, we show that transgenic mice expressing a dominant active mutant of DREAM in trigeminal neurons show increased responses following orofacial sensory stimulation, which correlates with a decreased expression of prodynorphin and brain-derived neurotrophic factor in trigeminal ganglia. Genome-wide analysis of trigeminal neurons in daDREAM transgenic mice identified cathepsin L and the monoglyceride lipase as two new DREAM transcriptional targets related to pain. Our results suggest a role for DREAM in the regulation of trigeminal nociception. This article is part of the special article series "Pain". |
