Abstract:
Breast cancer is the most common type of cancer. In the developmental stages of breast cancer, estrogens are strongly involved. As estrogen synthesis is regulated by the enzyme aromatase, targeting the activity of this enzyme represents a therapeutic option. The pineal hormone melatonin may exert a suppressive role on aromatase activity, leading to reduced estrogen biosynthesis. A melatonin-mediated decrease in the expression of aromatase promoters and associated genes would provide suitable evidence of this molecule's efficacy as an aromatase inhibitor. Furthermore, melatonin intensifies radiation-induced anti-aromatase effects and counteracts the unwanted disadvantages of chemotherapeutic agents. In this manner, this review summarizes the inhibitory role of melatonin in aromatase action, suggesting its role as a possible oncostatic molecule in breast cancer.
Insights
Melatonin may inhibit aromatase activity, reducing estrogen biosynthesis in breast cancer. This pineal hormone also enhances radiation therapy and mitigates chemotherapy side effects, suggesting its potential as an oncostatic agent.
Area of Science:
- Endocrinology
- Oncology
- Molecular Biology
Background:
- Breast cancer is the most common malignancy, with estrogens playing a key role in its development.
- Estrogen synthesis is primarily regulated by the enzyme aromatase.
- Targeting aromatase is a recognized therapeutic strategy for breast cancer.
Purpose of the Study:
- To review the inhibitory role of melatonin on aromatase activity.
- To explore melatonin's potential as an oncostatic agent in breast cancer therapy.
Main Methods:
- Review of scientific literature on melatonin and aromatase.
- Analysis of studies investigating melatonin's effects on aromatase promoters and associated genes.
- Examination of melatonin's interactions with radiation and chemotherapy.
Main Results:
- Melatonin may suppress aromatase activity, leading to decreased estrogen biosynthesis.
- Evidence suggests melatonin can reduce the expression of aromatase promoters and related genes.
- Melatonin enhances radiation-induced anti-aromatase effects and counteracts chemotherapy-related adverse effects.
Conclusions:
- Melatonin exhibits inhibitory effects on aromatase.
- Melatonin demonstrates potential as a therapeutic agent in breast cancer, possibly by reducing estrogen levels and augmenting conventional treatments.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
