Context-Dependent Temporal Changes in Hypnotics Involved in Suicide Attempts. [PDF]
Neuropsychopharmacol RepTemporal changes in hypnotics involved in suicide attempts showed context‐dependent shifts. Dual orexin receptor antagonists increased significantly, while benzodiazepine involvement declined only in overdose‐related attempts. Melatonin receptor agonists showed no significant trend during 2020.

Orexin receptor expression in human adipose tissue: effects of orexin-A and orexin-B [PDF]
Journal of Endocrinology, 2006 Orexin-A and orexin-B, via their receptors orexin-1 receptor (OX1R) and orexin-2 receptor (OX2R) have been shown to play a role in the regulation of feeding, body weight, and energy expenditure. Adipose tissue also contributes significantly to the maintenance of body weight by interacting with a complex array of bioactive peptides; however, there are ...

Neurobiology of the Orexin System and Its Potential Role in the Regulation of Hedonic Tone
Brain Sciences, 2022 Orexin peptides comprise two neuropeptides, orexin A and orexin B, that bind two G-protein coupled receptors (GPCRs), orexin receptor 1 (OXR1) and orexin receptor 2 (OXR2).

Activity of putative orexin neurons during cataplexy
Molecular Brain, 2022 It is unclear why orexin-deficient animals, but not wild-type mice, show cataplexy. The current hypothesis predicts simultaneous excitation of cataplexy-inhibiting orexin neurons and cataplexy-inducing amygdala neurons.

Presence of orexin A and orexin 1 receptor in the buffalo prostate
Italian Journal of Animal Science, 2010 The orexins A and B are two peptides discovered initially in the rat lateral hypothalamus involved in the regulation of some body functions such as food intake, sleep/wake cycle, arterial pressure and heart rate. They interact with two receptors defined &

Involvement of the Orexinergic System in Cancer: Antitumor Strategies and Future Perspectives
Applied Sciences, 2023 Peptides promote the mitogenesis and migration of tumor cells, and cancer cells overexpress peptide receptors. The involvement of the orexinergic system in cancer is reviewed here, including thirteen cancer types (e.g., adrenocortical adenoma, breast ...

Integrative Physiology of Orexins and Orexin Receptors
CNS & Neurological Disorders - Drug Targets, 2009 Recent studies have established that the orexin system is a critical regulator of sleep/wake states. Deficiency of orexin signaling results in the sleep disorder narcolepsy-cataplexy in humans, dogs, and rodents. These findings have brought about the possibility of novel therapies for sleep disorders including narcolepsy-cataplexy.
