Such a notion gets support from the clinical findings that mucosal healing in IBD patients is associated with improved prognosis, and reduced risk of relapse or colitis-associated cancer. It therefore becomes critical to understand the intracellular signals that regulate mucosal healing and gut barrier integrity. Focal adhesion kinase (FAK) is a non-receptor tyrosine kinase that critically modulates epithelial cell growth and mobility and has been associated with carcinogenesis. However, studies also suggest that FAK activation may promote mucosal healing under conditions of colitis, which should reduce the risk of colitis-associated cancer. These findings highlight a potentially transformative role for FAK in the context of IBD. Understanding the molecular mechanisms by which FAK influences gut barrier repair and mucosal integrity could offer novel therapeutic avenues for treating IBD and preventing its long-term complications. This review focuses on the potential role of FAK in promoting colitis-associated mucosal healing and the underlying molecular mechanisms driving these processes, offering critical insights into IBD pathogenesis and therapy.</p>","PeriodicalId":23778,"journal":{"name":"World Journal of Gastroenterology","volume":"31 33","pages":"105466"},"PeriodicalIF":5.4,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12418014/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145041483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the complex interplay between hormonal imbalances and liver dysfunction is essential for advancing targeted therapeutic strategies. This comprehensive review explores the pathophysiological mechanisms linking major endocrine disorders to liver disease, with a focus on the roles of the thyroid, parathyroid, pancreas, adrenal glands, and sex hormones. Thyroid dysfunction is associated with alterations in liver enzyme levels and metabolic regulation, often resulting in hepatic steatosis or cholestasis. Hyperparathyroidism and consequent hypercalcemia have been linked to hepatic calcifications. Insulin resistance, both hepatic and peripheral, contributes to excessive lipid accumulation in the liver, exacerbating steatotic changes. Adrenal gland disorders, particularly in the setting of chronic liver disease, impair cortisol metabolism and may worsen hepatic injury. Additionally, sex hormones such as estrogen and testosterone modulate the progression of liver fibrosis and influence the development of metabolic syndrome. The intricate relationship between endocrine and hepatic systems underscores the need for a multidisciplinary approach in the management of liver disease. Addressing underlying hormonal disturbances may enhance patient outcomes and prevent further hepatic deterioration. Future research should prioritize integrative therapeutic strategies that concurrently target endocrine and liver dysfunction.</p>","PeriodicalId":23778,"journal":{"name":"World Journal of Gastroenterology","volume":"31 32","pages":"108827"},"PeriodicalIF":5.4,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12400232/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144993628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
