The role of melatonin has been extensively investigated in pathophysiological conditions, including autism spectrum disorder (ASD). Reduced melatonin secretion has been reported in ASD and led to many clinical trials using immediate-release and prolonged-release oral formulations of melatonin. However, melatonin's effects in ASD and the choice of formulation type require further study. Therapeutic benefits of melatonin on sleep disorders in ASD were observed, notably on sleep latency and sleep quality. Importantly, melatonin may also have a role in improving autistic behavioral impairments. The objective of this article is to review factors influencing treatment response and possible side effects following melatonin administration. It appears that the effects of exposure to exogenous melatonin are dependent on age, sex, route and time of administration, formulation type, dose, and association with several substances (such as tobacco or contraceptive pills). In addition, no major melatonin-related adverse effect was described in typical development and ASD. In conclusion, melatonin represents currently a well-validated and tolerated treatment for sleep disorders in children and adolescents with ASD. A more thorough consideration of factors influencing melatonin pharmacokinetics could illuminate the best use of melatonin in this population. Future studies are required in ASD to explore further dose-effect relationships of melatonin on sleep problems and autistic behavioral impairments.

Melatonin (MT), an endogenous hormone secreted by pineal gland, has the sedative, anti-inflammatory and antioxidant functions. However, there are few studies on whether MT affects the proliferation and differentiation of antler chondrocytes. The present study investigated the influences of MT on the proliferation and differentiation of antler chondrocytes, explored its regulation on runt-related transcription factor 2 (RUNX2), NOTCH1 and sonic hedgehog (SHH) signaling, and elucidated their interplays.

Objectives: Triple negative breast cancer (TNBC) is a distinct subtype of breast cancer that has a poor prognosis due to the lack of effective therapeutic agents. Since a significant proportion of human surgical samples of TNBC expressed mRNA for the growth hormone (GH), growth hormone-releasing hormone (GHRH), and gonadotropin-releasing hormone (GnRH) receptors, and the mitogenic proliferative activity of GH, GHRH, and GnRH, have been identified as effective therapeutic targets for somatostatin and its analogs and GnRH analogs, Di Bella Method (DBM), a combination of hormonal analogs and vitamins, was introduced to target and inhibit solid tumors. The present study aimed to improve the prognosis of TNBC using DBM in women with TNBC.

Objectives: This study aimed to examine the relationship between salivary melatonin levels and impulsivity in humans, as the literature has not examined this relationship in healthy individuals.
Methods: We recruited 75 participants aged 18-55 years, measuring their salivary melatonin concentrations using an enzyme immunoassay and their impulsivity using the Barratt Impulsiveness Scale (BIS) scores.
Results: The participants' salivary melatonin levels were positively correlated with impulsivity.

Nicotine, the main toxic component of tobacco, directly or indirectly causes adverse effects on the liver metabolism. Melatonin, secreted by the pineal gland, has anti-apoptotic activity as well as antioxidant activity. The aim of this study was to reveal the antiapoptotic effects of melatonin in rats with experimentally induced chronic liver damage with nicotine.

This review explores the intricate relationship between glaucoma and circadian rhythm disturbances. As a principal organ for photic signal reception and transduction, the eye plays a pivotal role in coordinating the body's circadian rhythms through specialized retinal ganglion cells (RGCs), particularly intrinsically photosensitive RGCs (ipRGCs). These cells are critical in transmitting light signals to the suprachiasmatic nucleus (SCN), the central circadian clock that synchronizes physiological processes to the 24-hour light-dark cycle.
