Abstract
Title: BIO-WASTE PRODUCTS AS A SOURCE OF NUTRACEUTICALS TO TARGET THE COMMON TRAIT OF INFLAMMATION IN CANCER AND NEURODEGENERATION Project Summary The project entitled "Bio-waste products as a source of nutraceuticals to target the common trait of inflammation in cancer and neurodegeneration" aims to address two major global health challenges—cancer and neurodegenerative diseases—by leveraging an innovative, sustainable strategy rooted in circular economy principles. These two pathologies, although historically considered distinct, are now recognized to share common features, notably aging and chronic inflammation, which contribute to their onset and progression. Despite recent advances in biomedical technologies, the development of effective therapies remains slow and insufficient. This project seeks to fill this gap by identifying and validating bioactive compounds derived from food and agricultural waste that exert anti-inflammatory, anti-cancer, and neuroprotective effects. The overall goal is to identify low-cost and eco-sustainable nutraceutical molecules and candidate extracts from food and agricultural by-products capable of counteracting inflammation, a key driver of both cancer and neurodegeneration. The focus will be on bio-waste sources such as citrus waste and olive pomaces, chestnut shells (Castanea sativa), pomegranate and tomato peels. Using environmentally friendly extraction techniques, these by-products will be processed to obtain phytochemical-rich extracts with potential therapeutic properties. The project unfolds over 24 months and is structured into three interrelated work packages (WPs): WP1: Eco-sustainable production and characterization of bio-waste extracts This phase focuses on selecting and processing waste materials using green extraction techniques, such as supercritical fluid extraction, ultrasound-assisted extraction, and deep eutectic solvents. The resulting extracts will be chemically characterized (e.g., total phenolics, flavonoids, antioxidant activity) before and after undergoing a simulated in vitro digestion process that mimics gastrointestinal conditions. This ensures the extracts’ bioactivity in biologically relevant forms. WP2: Evaluation of anti-inflammatory activity in models of cancer and neurodegeneration The digested extracts will be tested on various in vitro models, including osteosarcoma (OS) cell lines and microglial cells (BV-2) either alone or co-cultured with neuron-like SH-SY5Y cells to simulate neuroinflammatory conditions. These tests will assess cytotoxicity, anti-inflammatory properties (e.g., cytokine modulation, NF-kB pathway inhibition), antioxidant capacity, and neuroprotective effects. Additionally, in vivo experiments will be carried out on transgenic Drosophila melanogaster models of Alzheimer’s and Parkinson’s diseases. Treated flies will be evaluated for lifespan, locomotor ability, memory, and biomolecular markers of inflammation, oxidative stress, and neurodegeneration. WP3: Molecular profiling and AI-assisted identification of active compounds Proteomic analyses using 2D electrophoresis and mass spectrometry will be performed on both cell and Drosophila samples to identify differentially expressed proteins involved in inflammation and disease pathways. These data will feed into a bioinformatic pipeline where Artificial Intelligence (AI) methods, such as machine learning and molecular docking, will help define the molecular descriptors and biological targets of the most promising nutraceutical compounds. This step will guide future compound optimization and structure–activity relationship (SAR) modeling. Expected Results and Scientific Impact: The project is expected to deliver: • Novel eco-sustainable extraction protocols for bioactive compounds from waste materials; • A panel of candidate nutraceutical extracts with validated anti-inflammatory, anti-cancer, and neuroprotective effects in pre
