Abstract:
DNA base excision repair (BER) is an evolutionarily conserved and essential DNA repair mechanism that acts as the major surveillance system for base lesions caused by endogenous and exogenous attacks. Therefore, BER is required for maintaining genomic stability under both physiological and pathological conditions. In this paper, we provide a brief review of the germline and somatic alterations of BER in cancer, with a particular focus on the core enzyme apurinic/ apyrimidinic endonuclease 1 (APE1), encoded by APEX1, and the mechanistic relationship to the development and treatment of cancer. Additionally, the review discusses the latest advances in BER-associated detection technologies and their potential clinical applications, underscoring the therapeutic potential of targeting BER for cancer prevention and intervention.

Nucleotide Excision Repair
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...
