Genotoxic substances can cause DNA damage at extremely low concentrations, leading to genetic mutations and an increased risk of tumor development. Therefore, controlling these impurities is crucial for the safety of chemicals and pharmaceutical products. CD Formulation, with years of industry experience and an advanced technology platform, offers comprehensive genotoxicity research services for nucleic acid drugs, ensuring product safety to high standards in a scientific manner.
The genotoxicity studies of nucleic acid drugs aims to identify and assess ingredients or impurities that may cause DNA damage directly or indirectly. If not controlled effectively, these issues can have profound effects on the genetic material of organisms, even resulting in the risk of genetic mutations. Due to the potential introduction or formation of new genotoxic impurities during drug synthesis, storage, and formulation processes, the breadth and depth of research are particularly important. Through comprehensive genotoxicity analysis and the prediction and control of potential genetic impacts, these studies ensure the anticipated safety of nucleic acid drugs in diverse and complex application environments. In addition, adhering to the strict requirements and control strategies for genotoxic impurities imposed by international regulatory bodies is key to strengthening compliance in drug development. Thus, conducting in-depth genotoxicity studies is not only for the safety of the research process but also for meeting regulatory compliance and market entry standards, jointly promoting the scientific and market-driven development of nucleic acid drugs.

As life expectancy increases, genetic integrity risks rise, leading to more age-related diseases and healthcare costs. Preventive strategies need to evaluate DNA threats, focusing on DNA damage response (DDR) and repair (DR) mechanisms. Alternative in vivo test systems are needed for research and toxicology risk assessment. Challenges include evaluating the combined toxicity of environmental genotoxins and anticancer drugs. This review suggests Caenorhabditis elegans as a model for studying genotoxin effects, highlighting its effectiveness in DDR and DR research. C. elegans supports large-scale in vivo screenings and sequencing. It discusses DDR and DR mechanisms and genotoxin study data, advocating for established protocols to utilize C. elegans in genetic toxicology.
