Cancer

53.5K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

What is Cancer?

14.0K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Area of Science:

  • Oncology
  • Endocrinology
  • Molecular Biology

Background:

  • Melatonin is a hormone primarily known for regulating sleep-wake cycles.
  • Emerging evidence indicates melatonin's involvement in cellular processes beyond circadian rhythm.
  • Its role in cancer pathogenesis warrants further investigation.

Purpose of the Study:

  • To elucidate the multifaceted roles of melatonin in cancer development.
  • To explore the specific pathways through which melatonin affects tumor growth and metastasis.
  • To assess the potential therapeutic applications of melatonin in oncology.

Main Methods:

  • Literature review of preclinical and clinical studies.
  • Analysis of molecular mechanisms involving melatonin signaling in cancer cells.
  • Examination of epidemiological data linking melatonin levels to cancer incidence and progression.

Main Results:

  • Melatonin demonstrates complex effects on cancer, acting as both an inhibitor and promoter depending on context.
  • Key pathways affected include cell proliferation, apoptosis, angiogenesis, and immune modulation.
  • Evidence suggests melatonin can influence metastasis through effects on cell adhesion and invasion.

Conclusions:

  • Melatonin is a significant modulator of cancer progression, impacting tumor growth and metastasis.
  • Understanding melatonin's diverse pathways is crucial for developing novel cancer therapies.
  • Melatonin holds promise as a potential therapeutic agent in cancer treatment strategies.
