A marked enhancement of a BLOC-1 gene, pallidin, associated with somnolent mouse models deficient in histamine transmission

Abstract

AbstractHistamine (HA) and orexin (Ox, or hypocretin) neurons act distinctly and synergistically in wake control. A double knock out mouse genotype lacking both HA and Ox shows all sleep disorders of human narcolepsy. We identified in this mouse brain a sharp upregulation of a BLOC-1 gene, pallidin that is associated with dramatic changes in the balance of cholinergic and aminergic systems in mice and an enhanced sleep in drosophila. This study demonstrates potential sleep disorders-associated compensatory mechanisms with pallid as a novel biomarker.
