Growth Hormone Increase Induced by Oral Administration of Melatonin in a Young Woman With Sleep Disturbances.

Growth hormone (GH) secretion by the pituitary is regulated by stimulatory and inhibitory pathways such as growth hormone releasing hormone (GHRH) and somatostatin, respectively, being also modulated by different neurotransmitters acting at the hypothalamic/pituitary level. The pineal gland hormone melatonin regulates GH secretion in many mammals, including humans, although its role in modulating GH secretion has been debated. We describe the case of a young woman chronically taking melatonin for sleep disturbances, referring to her general practitioner for flushing that appeared just after starting melatonin intake.

Background: This study investigates the protective properties of melatonin in an Parkinson's disease (PD) model, focusing on the underlying mechanisms involving heat shock proteins (HSPs).
Methods: Twelve adult male C57BL/6 mice were randomly divided into four groups (normal control, melatonin control, Parkinson's model, and melatonin treatment; = 3 per group) and housed in a single cage. 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was injected intraperitoneally in the Parkinson's model and treatment groups to establish a subacute PD model, while controls received saline.
Daily Lipolysis Gene Expression in Male Rat Mesenteric Adipose Tissue: Obesity and Melatonin Effects.

Melatonin is involved in various functions such as the timing of circadian rhythms, energy metabolism, and body mass gain in experimental animals. However, its effects on adipose tissue lipid metabolism are still unclear. This study analyzes the effects of melatonin on the relative gene expression of lipolytic proteins in rat mesenteric adipose tissue and free fatty acid (FFA) and glycerol plasma levels of male Wistar rats fed a high-fat (HFD) or maintenance diet.

Patients with chronic kidney disease (CKD) are at increased risk of acute kidney injury following exposure to contrast media. We evaluated the effect of melatonin, a potent antioxidant, as a protective strategy against contrast-induced acute kidney injury (CI-AKI), with a focus on molecular mechanisms. We randomized patients with an eGFR < 60 mL/min/1.
