Lipocalin-type prostaglandin D synthase produces prostaglandin D2 involved in regulation of physiological sleep.

Proc. Natl. Acad. Sci. U. S. A. 103(47) , 17949-54, (2006)

Prostaglandin (PG) D2 has been proposed to be essential for the initiation and maintenance of the physiological sleep of rats because intracerebroventricular administration of selenium tetrachloride (...

Prostaglandin D synthase in the prenatal ovine brain and effects of its inhibition with selenium chloride on fetal sleep/wake activity in utero.

J. Neurosci. 22(13) , 5679-86, (2002)

It has been proposed that prostaglandin (PG) D(2) induces physiological sleep in mammals by acting on sleep centers located in the anterior hypothalamus. In fetal sheep, definitive rapid-eye-movement ...

Inhibition of sleep in rats by inorganic selenium compounds, inhibitors of prostaglandin D synthase.

Proc. Natl. Acad. Sci. U. S. A. 88(20) , 9046-50, (1991)

Prostaglandin (PG) D2 has been postulated to be an endogenous sleep-promoting factor in rats, and SeCl4 and Na2SeO3 recently have been shown to inhibit the PGD synthase (prostaglandin-H2 D-isomerase, ...
