            Figure 5. Building blocks of the omics approach in PPM. Omics technologies are the cornerstone of PPM, encompassing high-throughput analyses such as
            genomics, transcriptomics, proteomics, and metabolomics/lipidomics. These approaches, when integrated with robust systems biology, bioinformatics, and
            computational tools, enable the comprehensive study of cellular mechanisms, interactions, and functions across tissues, organs, and the entire organism.
            By operating at the molecular level in a non-targeted and unbiased manner, omics technologies provide a deeper understanding of biological complexity
            and disease processes. 17
