Cellular genome is considered a dynamic blueprint of a cell since it encodes genetic information that gets temporally altered due to various endogenous and exogenous insults. Largely, the extent of genomic dynamicity is controlled by the trade-off between DNA repair processes and the genotoxic potential of the causative agent (genotoxins or potential carcinogens). A subset of genotoxins form DNA adducts by covalently binding to the cellular DNA, triggering structural or functional changes that lead to significant alterations in cellular processes via genetic (e. g., mutations) or non-genetic (e. g., epigenome) routes. Identification, quantification, and characterization of DNA adducts are indispensable for their comprehensive understanding and could expedite the ongoing efforts in predicting carcinogenicity and their mode of action. In this review, we elaborate on using Artificial Intelligence (AI)-based modeling in adducts biology and present multiple computational strategies to gain advancements in decoding DNA adducts. The proposed AI-based strategies encompass predictive modeling for adduct formation via metabolic activation, novel adducts' identification, prediction of biochemical routes for adduct formation, adducts' half-life predictions within biological ecosystems, and, establishing methods to predict the link between adducts chemistry and its location within the genomic DNA. In summary, we discuss some futuristic AI-based approaches in DNA adduct biology.
细胞基因组被认为是细胞的动态蓝图,因为它编码的遗传信息会因各种内源性和外源性损伤而随时间发生改变。在很大程度上,基因组动态性的程度受 DNA 修复过程与致病因素(遗传毒性物质或潜在致癌物质)的遗传毒性之间的权衡控制。一部分遗传毒性物质通过与细胞 DNA 共价结合形成 DNA 加合物,引发结构或功能变化,通过遗传(例如,突变)或非遗传(例如,表观基因组)途径导致细胞过程发生重大改变。DNA 加合物的鉴定、定量和特征描述对于全面了解它们是必不可少的,并可以加速对致癌性及其作用模式的预测的研究。在这篇综述中,我们详细阐述了基于人工智能(AI)的建模在加合物生物学中的应用,并提出了多种计算策略,以在解码 DNA 加合物方面取得进展。所提出的基于 AI 的策略包括通过代谢激活预测加合物形成、新的加合物鉴定、加合物形成的生化途径预测、生物生态系统内加合物半衰期预测,以及建立预测加合物化学与其在基因组 DNA 中位置之间关系的方法。总之,我们讨论了 DNA 加合物生物学中一些未来的基于 AI 的方法。
