Summary
Melatonin influences DNA repair pathways, offering potential in cancer therapy. This study explores how melatonin interacts with DNA repair mechanisms to combat cancer and enhance treatment efficacy.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- Genome integrity is maintained by DNA repair pathways.
- Defects in DNA repair are linked to human cancers.
- Targeting DNA damage response (DDR) is a promising cancer therapy strategy.
Purpose of the Study:
- To review the role of DNA repair pathways in cancer.
- To explore melatonin's regulatory functions in DDR.
- To examine melatonin's potential in combination cancer therapy.
Main Methods:
- Review of literature on DNA repair mechanisms (HR, NHEJ, BER, NER, MMR).
- Analysis of melatonin's biosynthesis, mode of action, and antioxidant properties.
- Synthesis of studies on melatonin's interaction with DDR and its therapeutic implications.
Main Results:
- Deficiencies in DNA repair pathways (HR, NHEJ, BER, NER, MMR) contribute to cancer risk.
- Melatonin modulates DDR at multiple levels (transduction, mediation, function).
- Melatonin exhibits antioxidant effects relevant to DNA protection.
Conclusions:
- Melatonin plays a significant role in regulating DNA repair and DDR.
- Melatonin's multifaceted actions suggest its potential as an anticancer agent.
- Combining melatonin with DNA-damaging agents may improve cancer treatment outcomes.

3.3K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

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...

02:25Overview of DNA Repair
34.4K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.
