Many roles for<unk>  have been suggested following research carried out using<unk>  analogues with a greater molecular stability and through measuring<unk> -like immunological <unk> -LI) response by injecting<unk>  antiserum and antibodies. Roles in endocrine regulation *Decreases basal corticotropin level and blocks its release. *Stimulates release of luteinizing hormone (LH). *Stimulates release of somatoliberin and somatotrophin secretion and inhibits somatostatin secretion. Roles in physiological processes *Can act as a stress limiting factor. *May have a direct or indirect effect on body temperature and alleviating hypothermia. *Can normalize blood pressure and myocardial contraction. *It has been shown to enhance the efficiency of oxidative phosphorylation in rat mitochondria in vitro, suggesting it may have antioxidant effects. *There is also conflicting evidence as to its involvement in<unk>  patterns. Some studies suggest a link between<unk>  and slow-wave<unk>  (SWS) promotion and suppression of paradoxical<unk> , (PS) while some studies show no correlation. Stronger effects on<unk>  have been noted for the synthesized analogues of<unk> . *It may affect human lens epithelial cell function via the MAPK pathway, which is involved in cell proliferation, differentiation, motility, survival, and apoptosis.
