A precision medicine ecosystem for Alkaptonuria through clinical and experimental knowledge management and sharing system for an integrated approach

PRIN 2022 PNRR Angeloni

Abstract

A precision medicine ecosystem for Alkaptonuria through clinical and experimental knowledge management and sharing system for an integrated approach Alkaptonuria (AKU) is a rare, debilitating genetic metabolic disorder caused by a mutation in the homogentisate 1,2-dioxygenase (HGD) gene. The condition leads to the accumulation of homogentisic acid (HGA), resulting in ochronosis and progressive damage to multiple organs, particularly joints, heart, and kidneys. Although recently approved therapies such as nitisinone (NTBC) can lower HGA levels, they fail to halt disease progression, address underlying inflammation, or reverse established tissue damage. Moreover, AKU lacks prognostic biomarkers, disease severity indicators, and effective combination therapies. Recent evidence also challenges the traditional view of AKU as a non-neurological disease by indicating potential involvement of the central and peripheral nervous systems. This project proposes an innovative precision medicine approach to address the multifaceted nature of AKU, combining preclinical biomedical research, patient data, and artificial intelligence (AI) tools. The project is structured around four main objectives: 1. Understanding the molecular mechanisms of AKU, utilizing patient-derived samples and in vitro disease models to investigate key factors such as inflammation, oxidative stress, lysosomal dysfunction, and DNA damage. 2. Exploring neurological involvement in AKU, particularly HGA-induced neuroinflammation and neurotoxicity using co-cultures of neuronal and microglial cells, along with blood-brain barrier (BBB) models. 3. Preclinical evaluation of novel therapeutic strategies, focusing on antioxidant molecules (e.g., N-acetylcysteine, ascorbic acid) and anti-inflammatory agents (e.g., methotrexate), with the aim of identifying more effective combination therapies. 4. Enhancing the ApreciseKUre digital ecosystem—a unique integrated AKU patient database—by incorporating clinical, molecular, and AI-assisted predictive tools to support patient stratification, biomarker discovery, and treatment personalization. The research integrates molecular biology, biochemistry, bioinformatics, and AI across five work packages (WPs). Key methodologies include: • Metabolomics (HPLC/NMR) to analyze patient blood samples; • Proteomic analyses (LC-MS/MS) of treated cellular models; • Imaging, Western blotting, immunofluorescence, RT-PCR, and ELISA for the analysis of oxidative and inflammatory markers; • Development of a Clinical Knowledge Portal (CKP) and AI tools to analyze integrated data from the ApreciseKUre platform. Two research units (Università di Siena and Università di Bologna) will collaborate to share expertise in experimental biochemistry, neurobiology, pharmacology, and computational biology. The expected results are: • New insights into AKU pathophysiology, particularly concerning brain involvement and lysosomal dysfunction; • Discovery of prognostic biomarkers and indicators of disease severity and progression; • Preclinical validation of effective drug combinations, addressing oxidative stress and inflammation in AKU; • Enhanced ApreciseKUre database, functioning as a dynamic clinical knowledge tool integrating patient data, in vitro results, and AI-driven models; • Publications in peer-reviewed journals, workshops, and engagement with AKU patient associations for knowledge dissemination. The deliverables include experimental reports, updated datasets for ApreciseKUre, AI-driven prediction modules, and at least four scientific publications. A kick-off and final scientific meeting are also planned, with interim workshops as necessary. This project addresses strategic goals within the PNRR thematic cluster “Human Wellbeing” and aligns with Italy’s national research strategies in biomedicine, biotechnology, and digital health. It contributes directly to the United Nations 2030 Agenda f
