Multi-omics data integration

Definition

Multi-omics data integration is the process of combining and analyzing data from various omics layers, such as genomics, transcriptomics, proteomics, and metabolomics, to gain a comprehensive understanding of biological systems. This approach allows researchers to explore the relationships between different molecular components and their contributions to cellular functions, disease mechanisms, and therapeutic responses. By integrating diverse datasets, scientists can uncover insights that single omics approaches may overlook.
