Melatonin Regulates Lipid Metabolism in Porcine Cumulus–Oocyte Complexes via the Melatonin Receptor 2

open access: yesAntioxidants, 2022
Previous studies suggest that the inclusion of melatonin (MTn) in in vitro maturation protocols improves the developmental competence of oocytes by scavenging reactive oxygen species (ROS). However, the molecular mechanisms integrating melatonin receptor

Melatonin Exerts Chondroprotective Effects Against Osteoarthritis by Promoting PI3K/AKT/FoxO3‐Mediated Mitophagy

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Osteoarthritis (OA) is a prevalent degenerative joint disease. This study combines bioinformatics analysis with in vivo and in vitro experiments to elucidate the molecular mechanisms through which melatonin (MT) regulates mitophagy to alleviate OA.

Melatonin receptor depletion suppressed hCG-induced testosterone expression in mouse Leydig cells

open access: yesCellular & Molecular Biology Letters, 2019
Melatonin receptors MT1 and MT2 (genes officially named MTNR1A and MTNR1B, respectively) play crucial roles in melatonin-mediated regulation of circadian rhythms, the immune system, and control of reproduction in seasonally breeding animals.

Modulation of human ovarian function by melatonin

open access: yesFrontiers in Bioscience-Elite, 2020
Melatonin, a hormone which is primarily released by the pineal gland, has a wide range of actions in the female reproductive tract. While the melatonin receptor subtype, MT3, has been identified in amphibian animals and birds, in humans and other mammals,

Melatonin abolished proinflammatory factor expression and antagonized osteoarthritis progression in vivo

open access: yesCell Death and Disease, 2022
Progressive structural changes in osteoarthritis (OA) involve synovial inflammation and angiogenesis, as well as activation of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α) and interleukin (IL)-8, and the angiogenic factor vascular ...

Melatonin alleviates lung injury in H1N1-infected mice by mast cell inactivation and cytokine storm suppression.

open access: yesPLoS Pathogens, 2023
Influenza A virus (IAV) H1N1 infection is a constant threat to human health and it remains so due to the lack of an effective treatment. Since melatonin is a potent antioxidant and anti-inflammatory molecule with anti-viral action, in the present study ...

Regulation of bone mass through pineal‐derived melatonin‐MT2 receptor pathway [PDF]

open access: yesJournal of Pineal Research, 2017
AbstractTryptophan, an essential amino acid through a series of enzymatic reactions gives rise to various metabolites, viz. serotonin and melatonin, that regulate distinct biological functions. We show here that tryptophan metabolism in the pineal gland favors bone mass accrual through production of melatonin, a pineal‐derived neurohormone.

Pharmacological and Mechanistic Interventions for Cognitive Impairment Associated With Schizophrenia: A Review of Registered Clinical Trials

open access: yesActa Psychiatrica Scandinavica, EarlyView.
ABSTRACT Background Schizophrenia is characterized by positive, negative, and cognitive symptoms. Current pharmacological treatments often fail to address cognitive deficits. In this review of clinical trials, we aim to identify studies that explore neurobiological (non‐psychological) strategies to address Cognitive Impairment Associated with ...

Novel approaches for drug development against chronic primary pain: A systematic review

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

The potential anti-cancer effects of melatonin on breast cancer

open access: yesExploration of Medicine, 2022
Melatonin is the primary hormone of the pineal gland that is secreted at night. It regulates many physiological functions, including the sleep-wake cycle, gonadal activity, free radical scavenging, immunomodulation, neuro-protection, and cancer ...
