Melatonin distribution reveals clues to its biological significance in basal metazoans.

open access: yesPLoS ONE, 2012
Although nearly ubiquitous in nature, the precise biological significance of endogenous melatonin is poorly understood in phylogenetically basal taxa.

Melatonin Reverses the Warburg-Type Metabolism and Reduces Mitochondrial Membrane Potential of Ovarian Cancer Cells Independent of MT1 Receptor Activation

open access: yesMolecules, 2022
Ovarian cancer (OC) is the most lethal gynecologic malignancy, and melatonin has shown various antitumor properties. Herein, we investigated the influence of melatonin therapy on energy metabolism and mitochondrial integrity in SKOV-3 cells and tested ...

Remodeling Of The Bone Tissue Of Rats Of Different Lines After Melatonin Effect [PDF]

open access: yes, 2016
The markers of remodeling of bone tissue (BT) were studied after the impact of pharmacologic dose of melatonin (5 mg/kg of the animal body weight) during 28 days for 3-months rats-males of Wistar and SHR lines.

Melatonin in Plants [PDF]

open access: yesNutrition Reviews, 2009
Once thought to be exclusively a molecule of the animal kingdom, melatonin has now been found to exist in plants as well. Among a number of actions, melatonin is a direct free radical scavenger and an indirect antioxidant. Melatonin directly detoxifies the hydroxyl radical (OH), hydrogen peroxide, nitric oxide, peroxynitrite anion, peroxynitrous acid ...

Analysis of melatonin content and gene expression in Chinese cherry leaves [PDF]

open access: yesE3S Web of Conferences, 2020
To investigate the accumulation characteristics and mechanism of melatonin in cherry leaves of different leaf ages, the melatonin content and the expression of synthetic genes in cherry leaves of different leaf ages were measured. The results showed that

Melatonin regulates gene expressions through activating auxin synthesis and signaling pathways

open access: yesFrontiers in Plant Science, 2022
BackgroundBoth melatonin and indole-3-acetic acid (IAA) are derived from tryptophan. And the most interesting and unsolved puzzle in melatonin research is that what is the relationship between melatonin and auxin?MethodsIn this study, we performed ...
