The aim was to study formulations encapsulated with the antioxidant curcumin to assess their ability protect against oxidative stress in a model of alcohol-related liver disease (ALD) combined with iron. HepG2 (VL-17A) cells were treated with iron (50 \u00b5M) alone or with alcohol (200 to 350 mM) over 72 h and markers of oxidative damage, cell death, and mitochondrial function were assessed. Nanoformulations encapsulating curcumin were also studied. VL-17A cells treated with both ethanol and iron showed significant decreases in cell viability (64%, p &lt; 0.0001) when compared to control, and a 56% decrease (p = 0.0279) when compared to iron-only treatment. Iron-alone treatment caused a 115% increase (p &lt; 0.0001) in ROS at 48 h as well as increases of up to 118% when treated with 200 mM ethanol + 50 \u03bcM iron (p &lt; 0.0001), compared to control DMEM. The study found that 10 \u00b5M curcumin DSPE-PEG increased cell viability by 17% and 41% when compared to control and iron treatment alone, respectively. Formulations reduced ROS by 36% (p = 0.0015) when compared to iron-alone treatment. In summary, encapsulated curcumin provided antioxidant capacity and reduced oxidative stress, demonstrating the therapeutic potential for curcumin formulations in ALD combined with iron dysregulation.<\/jats:p>","DOI":"10.3390\/biology14050455","type":"journal-article","created":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T10:40:48Z","timestamp":1745404848000},"page":"455","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Curcumin Nanocarriers in the Protection Against Iron- and Alcohol-Induced Oxidative Stress in a Cellular Model of Liver Disease"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2457-4001","authenticated-orcid":false,"given":"Lucy","family":"Petagine","sequence":"first","affiliation":[{"name":"Centre for Nutraceuticals, School of Life Sciences, University of Westminster, London W1W 6UW, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9944-8451","authenticated-orcid":false,"given":"Mohammed G.","family":"Zariwala","sequence":"additional","affiliation":[{"name":"Centre for Nutraceuticals, School of Life Sciences, University of Westminster, London W1W 6UW, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5361-4610","authenticated-orcid":false,"given":"Satyanarayana","family":"Somavarapu","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutics, UCL School of Pharmacy, London WC1N 1AX, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1912-3081","authenticated-orcid":false,"given":"Stefanie Ho Yi","family":"Chan","sequence":"additional","affiliation":[{"name":"Centre for Nutraceuticals, School of Life Sciences, University of Westminster, London W1W 6UW, UK"},{"name":"Department of Pharmaceutics, UCL School of Pharmacy, London WC1N 1AX, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9334-2525","authenticated-orcid":false,"given":"Vinood B.","family":"Patel","sequence":"additional","affiliation":[{"name":"Centre for Nutraceuticals, School of Life Sciences, University of Westminster, London W1W 6UW, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"399","DOI":"10.1016\/S0168-8278(12)61033-2","article-title":"EASL Clinical Practical Guidelines: Management of Alcoholic Liver Disease","volume":"57","author":"Mathurin","year":"2012","journal-title":"J.
