27530010 Low circulating Orexin A was found to be significantly associated with hyperlipidemia, obesity and obesity-related disorders in North Indian premenopausal women.
27008404 This is the first time a seasonal variation of hcrt-1 levels has been shown, demonstrating that the hcrt system is, like other neurotransmitter systems, subjected to long term modulation
26831553 Data indicate a positive correlation of nesfatin-1 and a negative correlation of orexin-A with body mass index.
26572581 This study showed that orexin A induced autophagy through the ERK pathway in HCT116 human colon cancer cells.
26555080 Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation is highly unlikely to be caused by mutations in the exons of the gene for hypocretin.
25957175 Results from homology and docking modeling show two alternative binding modes for orexin-A into orexin 1 receptor in concordance with what is known of G protein coupled receptors activation in general and the mutational data.
25953524 Study shows Ox immunoreactivity is decreased in the hypothalamus and pontine nuclei of infants who died from sudden infant death syndrome
25677777 Data suggest that interaction between the nociceptin/nociceptin receptor system and the orexin/orexin receptor system in neurons of the hypothalamus positively and negatively modulate complex and integrated responses to stress. [REVIEW]
25560205 Patients with schizophrenia had a significantly higher plasma HCRT level than healthy controls. Patients in the high-orexin subgroup had significantly fewer negative and disorganized symptoms, and tended to have fewer perseverative errors.
25515760 Orexin A upregulates the protein expression of OX1R and enhances the proliferation of SGC-7901 gastric cancer cells through the ERK signaling pathway.
