Role of the stability of deoxyribonucleoside triphosphate pool in the development and progression of tumors / 肿瘤研究与临床

ABSTRACT

The stability of deoxyribonucleoside triphosphate (dNTP) pool is essential for the normal synthesis of nuclear and mitochondrial DNA. The lack or excess of any dNTP may cause DNA damage and genomic instability, and increase mutation rate. Present studies have confirmed that the instability of dNTP pool is closely related to a variety of tumorigenesis. In addition, dNTP pool is involved in the development of tumor via multiple pathways, while the mechanisms of tumors caused by the instability of dNTP are complicated. This paper discusses the relationship between the stability of dNTP pool and DNA damage repair to provide a theoretical basis for early diagnosis and targeted treatment of tumors.
