The full extent of their cellular mechanisms, which is essential to balance efficacy and toxicity, is often unclear. In addition, the use of many anticancer drugs is limited by dose-limiting toxicities as well as the development of drug resistance.
WebDNA damage is a general term that is used for the induction of adducts and/or DNA strand breakage. DNA adducts include chemical substances covalently bound to DNA and … WebThe DNA damage that is left unrepaired may also disrupt cellular processes by obstructing the DNA and RNA synthesizing machineries and introduce wrong bases into the DNA. These types of mistakes often result in mutation leading to loss or inappropriate expression of affected genes.
