Phytochemicals, with their diverse impacts on cancer cell growth and metabolism, represent promising candidates for such strategies. Combining compounds like curcumin (Curc) and ursolic acid (UA), which target multiple pathways, can be advantageous in slowing tumor progression. Previous studies revealed the synergistic effects of Curc\u2009+\u2009UA in reducing tumor growth in a PCa allograft model. In this study, diet\u2010based interventions were evaluated using two transgenic mouse models of PCa. Mice fed a Curc\u2009+\u2009UA\u2010enriched diet exhibited significant inhibition of prostate tumor progression compared to single\u2010agent diets in both HiMyc and PTEN knockout mouse models. Protein analyses of ventral prostate tissues from HiMyc mice indicated that the combination suppressed oncogenic signaling pathways, including STAT3, AKT, and mTORC1, while modulating cell regulatory proteins to inhibit tumor cell proliferation. Furthert mechanistic studies in mouse and human PCa cell lines confirmed that Curc\u2009+\u2009UA exerted pleiotropic effects by influencing oncogenic signaling, cell cycle regulation, mitochondrial function, unfolded protein response (UPR), and apoptosis, collectively contributing to its synergistic efficacy. These findings highlight the potential of Curc\u2009+\u2009UA to inhibit PCa progression through multitargeted mechanisms. The combination's superior efficacy over single agents underscores its promise as a chemopreventive or therapeutic strategy. This study provides a strong rationale for further mechanistic investigations and clinical development of Curc\u2009+\u2009UA for PCa prevention and treatment.<\/jats:p>","DOI":"10.1002\/mc.70000","type":"journal-article","created":{"date-parts":[[2025,7,6]],"date-time":"2025-07-06T15:19:46Z","timestamp":1751815186000},"page":"1487-1499","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Synergistic Inhibition of Prostate Cancer Progression in Mice With a Combination of Curcumin and Ursolic Acid in the Diet"],"prefix":"10.1002","volume":"64","author":[{"given":"Chelsea A.","family":"Friedman","sequence":"first","affiliation":[{"name":"Division of Pharmacology and Toxicology, College of Pharmacy The University of Texas at Austin Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Achinto","family":"Saha","sequence":"additional","affiliation":[{"name":"Division of Pharmacology and Toxicology, College of Pharmacy The University of Texas at Austin Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Clark","sequence":"additional","affiliation":[{"name":"Division of Pharmacology and Toxicology, College of Pharmacy The University of Texas at Austin Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carly","family":"Wilder","sequence":"additional","affiliation":[{"name":"Division of Pharmacology and Toxicology, College of Pharmacy The University of Texas at Austin Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordan","family":"Wright","sequence":"additional","affiliation":[{"name":"Division of Pharmacology and Toxicology, College of Pharmacy The University of Texas at Austin Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4233-6728","authenticated-orcid":false,"given":"John","family":"DiGiovanni","sequence":"additional","affiliation":[{"name":"Division of Pharmacology and Toxicology, College of Pharmacy The University of Texas at Austin Austin Texas USA"},{"name":"Dell Pediatric Research Institute, Dell Medical School The University of Texas at Austin Austin Texas USA"},{"name":"Center for Molecular Carcinogenesis and Toxicology The University of Texas at Austin Austin Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,6]]},"reference":[{"key":"e_1_2_12_2_1","unstructured":"K.Statistics Key Statistics for Prostate Cancer\/Prostate Cancer Facts.2025.https:\/\/www.cancer.org\/cancer\/types\/prostate-cancer\/about\/key-statistics.html."},{"key":"e_1_2_12_3_1","unstructured":"P.
