DREAM Repression and Dynorphin Expression

The experience of pain in response to noxious stimuli serves a crucial biological purpose: it alerts a living organism to environmental dangers, inducing behavioral responses that protect the organism from further damage. In contrast, chronic pain arising from disease states and/or pathological functioning of the nervous system offers no advantage and may be debilitating to those afflicted. Control and treatment of chronic pain remain major clinical challenges. The calcium-sensing protein DREAM (Downstream Regulatory Element Antagonistic Modulator) is a putative transcriptional repressor involved in modulating pain (Ref.1).

DREAM is constitutively expressed in certain neurons and transcriptional activity of the repressor DREAM depends on its high affinity binding to a DRE (Downstream Response Element) site in target genes, which is important in regulating [...]
