Yet, challenges remain in the field due to an increasing organ allograft shortage as well as significant waitlist mortality. With these challenges, organ allocation policies have been developed and are constantly being modified to result in more efficient organ allocation. One tool that has been explored to improve the field of liver transplantation is artificial intelligence, which is an umbrella term for techniques such as machine learning and deep learning. This review article explores the use of artificial intelligence in the field of liver transplantation. Specifically, studies have shown potential applications of artificial intelligence in improving waitlist mortality models, assessing allograft characteristics, using large language models for research question development and patient education, developing post-transplant models, as well as predicting multiple risk factors such as cardiovascular disease, infection, graft failure, malignancy, graft fibrosis, and pneumonia. However, even with these studies, several limitations for the use of artificial intelligence exist such as biased data sets leading to biased model development, lack of extensive validation of the artificial intelligence models, and the need for large datasets for model development. With additional studies evaluating the use of artificial intelligence and wide-scale validation of these studies highlighted, the use of artificial intelligence may transform the field of transplantation in the future.</div></div>","PeriodicalId":37786,"journal":{"name":"Transplantation Reports","volume":"10 2","pages":"Article 100173"},"PeriodicalIF":0.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143429948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, allo-HCT carries significant risks of morbidity and mortality due to relapse and transplant-related complications. Recurrent mutations in mitochondrial DNA (mtDNA) have been identified as significant prognostic indicators for MDS outcomes following allo-HCT. However, the biological mechanisms of mtDNA mutations remain unclear. Thus, here we performed deep variant phenotyping by integrating computational biophysics and structural genomics approaches to reveal the molecular mechanisms underlying mtDNA variant dysfunction. This emerging genomics discipline employs structural models, molecular mechanic calculations, and accelerated molecular dynamic simulations to analyze gene products, focusing on their structures and motions that determine their function. We applied this methodology on the variants in the mitochondria-encoded complex I genes that are associated with MDS pathobiology and prognosis after allo-HCT. Our results demonstrate that this approach significantly outperforms conventional analytical methods, providing enhanced and more accurate information to support the potential pathogenicity of these variants and better infer their dysfunctional mechanisms. We conclude that the adoption and further expansion of computational structural genomics approaches, as applied to the mitochondrial genome, have the potential to significantly increase our understanding of molecular mechanisms underlying the disease. Our study lays a foundation for translating mitochondrial biology into clinical applications, which will advance the integration of precision medicine with allo-HCT.</div></div>","PeriodicalId":37786,"journal":{"name":"Transplantation Reports","volume":"10 1","pages":"Article 100171"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143182232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
