Abstract:
Melatonin, the major secretory product of the pineal gland, not only regulates circadian rhythms, mood, and sleep but also has actions in neoplastic processes which are being intensively investigated. Melatonin is a promising molecule which considered a differentiating agent in some cancer cells at both physiological and pharmacological concentrations. It can also reduce invasive and metastatic status through receptors MT1 and MT2 cytosolic binding sites, including calmodulin and quinone reductase II enzyme, and nuclear receptors related to orphan members of the superfamily RZR/ROR. Melatonin exerts oncostatic functions in numerous human malignancies. An increasing number of studies report that melatonin reduces the invasiveness of several human cancers such as prostate cancer, breast cancer, liver cancer, oral cancer, lung cancer, ovarian cancer, etc. Moreover, melatonin's oncostatic activities are exerted through different biological processes including antiproliferative actions, stimulation of anti-cancer immunity, modulation of the cell cycle, apoptosis, autophagy, the modulation of oncogene expression, and via antiangiogenic effects. This review focuses on the oncostatic activities of melatonin that targeted cell cycle control, with special attention to its modulatory effects on the key regulators of the cell cycle, apoptosis, and telomerase activity.
Insights
Melatonin, a pineal gland hormone, shows promise in cancer treatment by inhibiting tumor growth and spread. It influences cell cycle, apoptosis, and telomerase activity, offering potential anti-cancer strategies.
Area of Science:
- Oncology
- Endocrinology
- Molecular Biology
Background:
- Melatonin, the primary pineal gland hormone, regulates circadian rhythms and exhibits significant oncostatic functions in various human malignancies.
- Its anti-cancer properties are attributed to its ability to act as a differentiating agent and reduce cancer cell invasiveness and metastasis.
- Melatonin interacts with specific receptors (MT1, MT2) and intracellular targets, influencing neoplastic processes.
Approach:
- This review synthesizes current research on melatonin's oncostatic activities, focusing on its role in cell cycle regulation.
- It examines melatonin's modulatory effects on key cell cycle regulators, apoptosis, and telomerase activity.
- The review also considers melatonin's interactions with various cellular pathways, including anti-proliferative, immune-stimulatory, and anti-angiogenic mechanisms.
Key Points:
- Melatonin demonstrates oncostatic effects across numerous cancers, including prostate, breast, liver, and lung cancer.
- It inhibits cancer cell proliferation, modulates the cell cycle, induces apoptosis and autophagy, and suppresses angiogenesis.
- Melatonin's mechanisms involve direct interaction with cell cycle regulators, apoptosis pathways, and telomerase, as well as indirect immune modulation.
Conclusions:
- Melatonin is a promising molecule with diverse oncostatic activities, particularly in regulating cell cycle control, apoptosis, and telomerase.
- Its multifaceted mechanisms offer potential therapeutic strategies for various human cancers.
- Further investigation into melatonin's role in cancer treatment is warranted.
