P — PopulationHuman metabolic systems across different tissues, organs, sex, and age groups

C — ComparatorPrevious human metabolic models and traditional GEM reconstruction methods
O — OutcomesEnhanced precision and biological relevance of metabolic models, tissue/organ-specific metabolic features, whole-body dynamic simulation capabilities

Bottom Line

This methodological study presents Human2, an enhanced genome-scale metabolic model that incorporates large language models for improved precision in human metabolism research. The model offers sex- and age-specific customisation and whole-body dynamic simulation capabilities, potentially advancing personalised medicine approaches. While the computational innovation is promising, the abstract lacks crucial validation metrics and statistical evidence for claimed improvements. The identified differences in arachidonic acid and leukotriene metabolism warrant further investigation. For Australian clinicians, this tool could eventually support more precise metabolic disease management and drug therapy optimisation, though clinical validation remains necessary. The collaborative framework may accelerate metabolic research, but practitioners should await peer-reviewed validation studies before considering clinical applications. This represents an important step toward more sophisticated metabolic modelling but requires careful evaluation of real-world performance.

Abstract

Genome-scale metabolic models (GEMs) have become essential tools for understanding human metabolism. Here, we introduce Human2, a consensus human GEM with enhanced precision and biological relevance, which leverages large language models (LLMs) and GitHub Action checks to streamline automated, efficient, and collaborative curation. Human2 supports the reconstruction of tissue- and organ-specific models tailored to sex- and age-specific human groups. By integrating transcriptomic, proteomic, and kinetic data, we reveal distinct metabolic features across these groups, such as significant differences in arachidonic acid and leukotriene metabolism. The specific models were integrated into a dynamic whole-body framework, marking an enzyme-constrained dynamic model that simulates interorgan metabolite exchanges under varying nutritional states, from feeding to fasting. Our work highlights the transformative role of LLMs in GEM reconstruction and introduces a whole-body dynamic simulation that integrates kinetic data, offering a powerful resource for multiscale human metabolism modeling.
