Our personalized medicine investigations extend the concepts of precision medicine to the individual, assessing multiple omics during longitudinal profiling.
Omics analyses and integration requires extensive processing. MathIOmica and PyIOmica provide a user-friendly framework for handling downstream analysis and visualization.
Creating models necessitates robust omics datasets, particularly for time series analyses and network inference. We are creating multiple such sets available to the community.

In a proof-of-principle clinical trial, we monitored a generally healthy individual and carried out integrative profiling on saliva before and after vaccination with the pneumococcal PPSV23 vaccine. This is to our knowledge the most extensive saliva-focused omics dataset on an individual, covering 100+ timepoints over one year. The period covers a healthy (baseline) period, as well as comprehensive monitoring of innate and adaptive immune responses following vaccination.
Mias, G.I., Singh, V.V., Rogers, L.R.K. et al. Longitudinal saliva omics responses to immune perturbation: a case study. Sci Rep 11, 710 (2021).
Abstract: "Saliva omics has immense potential for non-invasive diagnostics, including monitoring very young or elderly populations, or individuals in remote locations. In this study, multiple saliva omics from an individual were monitored over three periods (100 timepoints) involving: (1) hourly sampling over 24 h without intervention, (2) hourly sampling over 24 h including immune system activation using the standard 23-valent pneumococcal polysaccharide vaccine, (3) daily sampling for 33 days profiling the post-vaccination response. At each timepoint total saliva transcriptome and proteome, and small RNA from salivary extracellular vesicles were profiled, including mRNA, miRNA, piRNA and bacterial RNA. The two 24-h periods were used in a paired analysis to remove daily variation and reveal vaccination responses. Over 18,000 omics longitudinal series had statistically significant temporal trends compared to a healthy baseline. Various immune response and regulation pathways were activated following vaccination, including interferon and cytokine signaling, and MHC antigen presentation. Immune response timeframes were concordant with innate and adaptive immunity development, and coincided with vaccination and reported fever. Overall, mRNA results appeared more specific and sensitive (timewise) to vaccination compared to other omics. The results suggest saliva omics can be consistently assessed for non-invasive personalized monitoring and immune response diagnostics."

Abstract: "Longitudinal deep multiomics profiling, which combines biomolecular, physiological, environmental and clinical measures data, shows great promise for precision health. However, integrating and understanding the complexity of such data remains a big challenge. Here we utilize an individual-focused bottom-up approach aimed at first assessing single individuals’ multiomics time series, and using the individual-level responses to assess multi-individual grouping based directly on similarity of their longitudinal deep multiomics profiles. We used this individual-focused approach to analyze profiles from a study profiling longitudinal responses in type 2 diabetes mellitus. After generating periodograms for individual subject omics signals, we constructed within-person omics networks and analyzed personal-level immune changes. The results identified both individual-level responses to immune perturbation, and the clusters of individuals that have similar behaviors in immune response and which were associated to measures of their diabetic status."

"Personalized medicine is expected to benefit from combining genomic information with regular moni- toring of physiological states by multiple high- throughput methods. Here, we present an integrative personal omics profile (iPOP), an analysis that combines genomic, transcriptomic, proteomic, metabolomic, and autoantibody profiles from a single individual over a 14 month period. Our iPOP analysis revealed various medical risks, including type II diabetes. It also uncovered extensive, dynamic changes in diverse molecular components and biological pathways across healthy and diseased conditions. Extremely high-coverage genomic and transcriptomic data, which provide the basis of our iPOP, discovered extensive heteroallelic changes during healthy and diseased states and an unexpected RNA editing mechanism. This study demonstrates that longitudinal iPOP can be used to interpret healthy and disease states by connecting genomic information with additional dynamic omics activity."

Our research interests lie in systems medicine and dynamics. We are an interdisciplinary team that focuses on developing theory and frameworks for studying dynamics, the application of longitudinal monitoring to evaluate and interpret microscopic molecular signatures (omics) and macroscopic physiological measurements, and integrate these to identify collective temporal trends that reflect the physiological state of a person. Our long-term vision is to develop innovative dynamics methods, bring individualized longitudinal medicine to the clinic for all, and automate the monitoring and evaluation of active personnel (astronauts), as well as improve diagnostics in populations with restricted access to healthcare.
