Oncostatic-Cytoprotective Effect of Melatonin and Other Bioactive Molecules: A Common Target in Mitochondrial...

Area of Science:

• Biochemistry
• Cell Biology
• Neuroscience

Background:

• Melatonin (5-methoxy-N-acetyltryptamine) is known for its oncostatic and antiproliferative effects.
• Paradoxically, melatonin also demonstrates significant scavenger, cytoprotective, and anti-apoptotic properties in neurodegeneration models, including Alzheimer's and Parkinson's diseases.
• Similar effects have been observed with other bioactive molecules like resveratrol and vitamin E derivatives.

Purpose of the Study:

• To review the historical and general aspects of melatonin.
• To explore the relationship between cancer, neurodegeneration, and the metabolome.
• To discuss the potential effects of melatonin and other bioactive molecules on metabolic and mitochondrial dynamics.

Main Methods:

• Literature review focusing on melatonin's properties.
• Analysis of studies on cancer and neurodegeneration metabolomes.
• Examination of research on mitochondrial function and bioactive molecules.

Main Results:

• Neoplastic pathologies and neurodegeneration share alterations in metabolome, mitochondrial function, and oxygen consumption.
• The oncostatic and cytoprotective actions of melatonin and similar molecules may be rationalized by their impact on mitochondrial function.
• Different metabolic and mitochondrial contexts influence the efficacy of these molecules.

Conclusions:

• A common underlying mechanism may explain the oncostatic and cytoprotective effects of melatonin and other examined bioactive molecules.
• Understanding these mechanisms could lead to novel therapeutic strategies for both cancer and neurodegenerative diseases.
• Further research into metabolic and mitochondrial dynamics is warranted.
