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.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

The Cell Cycle Control System02:11

The Cell Cycle Control System

The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent cell. It is the cell cycle that leads to the formation of an entire organism from a single-cell zygote. Besides, cell division also functions in the renewal or repair of tissues in adult multicellular eukaryotes. For example, in the bone marrow, the stem cells divide to form new blood cells. Although essential for several functions, cell...
