| Urolithins are gut microbiota–derived dibenzopyran-6-one metabolites formed from ellagitannins → ellagic acid. They are the bioactive, systemically relevant forms responsible for most of the anticancer, mitochondrial, and signaling effects attributed to pomegranate and berry consumption. Ellagic acid itself is largely confined to the gut lumen; urolithins are what reach circulation and tissues. Urolithin A (UA), Most studied; mitophagy, anticancer, anti-inflammatory Humans fall into urolithin metabotypes: Metabotype Description Approx. Population A Produces UA (best profile) ~40% B Produces UB ± UA ~25–30% 0 Non-producer ~30% ROS Modulation (Context-Dependent) Cancer cells: -Mild ROS ↑ or redox stress → apoptosis, growth arrest Normal cells: -ROS ↓, improved mitochondrial efficiency This duality is why urolithins are less chemo-antagonistic than classic antioxidants. Anticancer Signaling ↓ PI3K/AKT/mTOR ↓ Wnt/β-catenin ↓ NF-κB, STAT3 Cell-cycle arrest (G1/S) Unlike sulforaphane or NAC, urolithins: -Do not strongly upregulate NRF2 in cancer cells -May normalize NRF2 signaling in normal cellsDirect Urolithin A Supplements: Bypass microbiome dependency Urolithin A–type activity — Cancer vs Normal Cell Effects

| Tumor-Associated Macrophages (TAMs) TAMs are a type of immune cell found abundantly within the tumor microenvironment. They originate from circulating monocytes that differentiate into macrophages upon migrating into tissues. TAMs produce various growth factors, such as epidermal growth factor (EGF) and transforming growth factor-beta (TGF-β), which can directly stimulate tumor cell proliferation and survival. By secreting vascular endothelial growth factor (VEGF) and other pro-angiogenic factors, TAMs facilitate the formation of new blood vessels, ensuring that tumors receive an adequate supply of oxygen and nutrients. High densities of TAMs are found in many tumor types, including breast, lung, colorectal, and pancreatic cancers, among others. high infiltration of TAMs in tumors is correlated with worse overall survival, aggressive disease, increased metastatic potential, and resistance to therapy. |
