Insights

Genomic DNA damage is constant, but DNA repair mechanisms maintain stability and prevent cancer. This review covers major DNA repair pathways and methods to assess their efficiency for cancer therapy and drug development.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • Cellular genomic DNA faces constant damage from internal and external sources, potentially reaching 10^4-10^5 lesions daily per cell.
  • Unrepaired DNA damage, especially during S phase, can cause mutations in critical genes, leading to cancer.
  • DNA repair is crucial for maintaining genomic stability and preventing cellular transformation.

Purpose of the Study:

  • To review major DNA damage repair pathways.
  • To discuss methods for assessing DNA repair capacity and efficiency.
  • To highlight the significance of DNA repair in cancer development and therapy.

Main Methods:

  • Literature review of major DNA damage repair pathways.
  • Discussion of functional assays for measuring DNA repair system activity.
  • Analysis of advantages and limitations of different assessment approaches.

Main Results:

  • Identification of key DNA damage repair pathways.

Overview of DNA Repair

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.

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...

DNA Damage can Stall the Cell Cycle

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...
