These alterations promote significant dysfunction in adipose tissue and liver metabolism through cytokine production. Growing evidence indicates that the interaction between hepatokines and adipokines plays a central role in the development of metabolic and hepatic abnormalities in women with PCOS. This narrative review was conducted to analyze the relationship between adipose tissue dysfunction and liver metabolic impairment in women with PCOS, emphasizing the involvement of hepatokines and adipokines in insulin resistance, inflammation, hepatic steatosis, hepatic fibrosis and MetS. From this perspective, contemporary clinical, biochemical, and molecular studies were reviewed to evaluate how adipocyte-derived factors and hepatocyte-derived cytokines influence metabolic homeostasis in the liver and adipose tissue in women with PCOS. Increased visceral adiposity in PCOS enhances the release of free fatty acids (FFAs) to the liver, resulting in hepatotoxicity, oxidative stress, and hepatic inflammation. Several hepatokines, including fetuin-A, angiopoietin-like protein 3 (ANGPTL3), selenoprotein P(Sep-P), and hepassocin (HPS), show abnormal circulating levels in PCOS and are strongly associated with insulin resistance, dyslipidemia, and progression to hepatic steatosis. In contrast, fibroblast growth factor 21 (FGF-21), follistatin, and interleukin (IL-6) may exert dual effects. Adipokines, such as resistin, visfatin, apelin, and retinol-binding protein 4 (RBP-4), contribute to chronic inflammation, impaired glucose metabolism, androgen excess, and hepatic steatosis and fibrosis. Some of these adipokines, such as leptin and vaspin, may exert both beneficial and detrimental effects, while others, including chemerin and omentin, appear to play predominantly beneficial roles in metabolism. Reduced adiponectin-to-leptin levels further aggravate metabolic dysfunction. These changes indicate that adipose tissue\u2013liver crosstalk is a key mechanism linking PCOS and MetS. Overall, metabolic disturbances in PCOS are strongly mediated by dysregulated communication between adipose tissue and the liver. Altered hepatokine and adipokine profiles contribute to insulin resistance, liver dysfunction, hypertension and the development of MetS in women with PCOS. Understanding these intricate interactions may support the early identification of high-risk patients and the development of targeted therapeutic strategies.<\/jats:p>","DOI":"10.3390\/metabo16060393","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T17:18:16Z","timestamp":1780679896000},"page":"393","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Relationship Between Adipose Tissue and Liver Dysfunction in Women with Polycystic Ovary Syndrome and Metabolic Syndrome"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1292-2515","authenticated-orcid":false,"given":"Sebasti\u00e3o Freitas","family":"de Medeiros","sequence":"first","affiliation":[{"name":"Department of Gynecology and Obstetrics, Medical School, Federal University of Mato-Grosso, Cuiab\u00e1 78060-900, Brazil"},{"name":"Tropical Institute of Reproductive Medicine, Cuiab\u00e1 78043-306, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gustavo Arantes Rosa","family":"Maciel","sequence":"additional","affiliation":[{"name":"Discipline of Gynecology, S\u00e3o Paulo University, S\u00e3o Paulo 05403-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zhang, Z., Pang, Y., Shen, J., Chen, W., Hao, C., and Lei, Z.
