INTRODUCTION

Nanotechnology has brought about revolutionary advancements across various industries, offering unparalleled opportunities for innovation and progress. However, alongside its benefits, the increasing utilization of nanomaterials has raised concerns regarding their potential adverse effects on human health and the environment [1]. In response, the field of nanotoxicology has emerged to assess the hazards and risks associated with these engineered nanomaterials. Traditional toxicological approaches often struggle to fully elucidate the complex interactions between nanomaterials and biological systems [2]. In this context, the integration of systems biology into nanotoxicology holds immense promise, offering a holistic framework to dissect and understand the intricate mechanisms underlying nanomaterial toxicity. In response to these concerns, the field of nanotoxicology has emerged as a critical discipline aimed at assessing the hazards and risks associated with nanomaterial exposure. Traditional toxicological approaches, rooted in empirical observations and endpoint measurements, often fall short in elucidating the complex interactions between nanomaterials and biological systems [3, 4]. The dynamic and multifaceted nature of nanotoxicity necessitates a paradigm shift towards more holistic and mechanistic frameworks to unravel the underlying mechanisms driving adverse outcomes. Systems biology, with its integrative and interdisciplinary approach, offers a promising avenue for advancing our understanding of nanotoxicology. By elucidating the interconnectedness of biological systems across multiple scales, from molecules to organisms, systems biology provides a comprehensive framework to dissect the intricate pathways and networks perturbed by nanomaterial exposure. Leveraging high-throughput omics technologies, computational modeling, and network analysis, systems biology enables the identification of key biomarkers, pathways, and molecular signatures indicative of nanomaterial toxicity [5,6 ].

Understanding nanomaterial hazard and risk

Nanomaterials exhibit unique physicochemical properties that distinguish them from their bulk counterparts, endowing them with distinctive behaviors and interactions at the nano-bio interface. These characteristics can influence their biological fate, including cellular uptake, distribution, and toxicity. Traditional toxicological assessments typically rely on endpoint measurements and empirical models, overlooking the dynamic and interconnected nature of biological systems. In contrast, systems biology approaches leverage high-throughput omics technologies, computational modeling, and network analysis to capture the multifaceted responses elicited by nanomaterial exposure [7]. By integrating data across different biological scales, from molecular pathways to organ systems, systems biology enables a more comprehensive understanding of nanotoxicity, facilitating the identification of key biomarkers and pathways predictive of adverse outcomes [8].

Emerging systems biology approaches

Recent advancements in systems biology have paved the way for innovative strategies to unravel the complexities of nanotoxicology. Multi-omics profiling, encompassing genomics, transcriptomics, proteomics, and metabolomics, offers a holistic view of cellular responses to nanomaterials, unveiling intricate molecular signatures indicative of toxicity mechanisms. Networkbased analysis frameworks, such as pathway enrichment and gene regulatory network modeling, provide insights into the interconnectedness of biological processes perturbed by nanomaterials, elucidating underlying toxicity pathways and potential modes of action. Furthermore, the integration of experimental data with computational models enables predictive toxicology assessments, facilitating the extrapolation of findings across different nanomaterials and biological systems [9, 10].

METHODS

Selection of nanomaterials: Various types of nanomaterials were selected for the study, representing a range of compositions, sizes, and surface properties. These included commonly used nanomaterials such as metal nanoparticles (e.g., silver, gold), metal oxide nanoparticles (e.g., titanium dioxide, zinc oxide), carbonbased nanomaterials (e.g., carbon nanotubes, graphene), and quantum dots.

Cell culture and exposure: Human cell lines (e.g., lung epithelial cells, macrophages) or primary cell cultures were utilized to assess the biological responses to nanomaterial exposure. Cells were cultured under standard conditions and exposed to nanomaterials at relevant concentrations and exposure durations.

High-throughput omics profiling: Genomics, transcriptomics, proteomics, and metabolomics analyses were conducted to comprehensively characterize the cellular responses to nanomaterial exposure. Total RNA, proteins, or metabolites were extracted from treated cells, and high-throughput sequencing or mass spectrometry techniques were employed to generate omics data.

Computational modeling and network analysis: Computational models, including differential gene expression analysis, pathway enrichment analysis, and gene regulatory network modeling, were employed to analyze omics data and identify key molecular pathways and networks perturbed by nanomaterial exposure. Network-based approaches were utilized to uncover the interconnectedness of biological processes and prioritize critical nodes for intervention.

CONCLUSION

The integration of systems biology into nanotoxicology represents a paradigm shift in our approach to understanding the hazards and risks associated with nanomaterial exposure. By embracing a mechanistic perspective, enabled by high-throughput omics technologies, computational modeling, and network analysis, researchers have made significant strides in deciphering the intricate pathways and mechanisms underlying nanotoxicity. Through multiomics profiling, researchers can capture the dynamic responses of biological systems to nanomaterial exposure, unveiling molecular signatures indicative of toxicity mechanisms.
