Patients with HCC often have abnormal purine and uric acid metabolism, but their relationship with prognosis is unclear.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Here, we collected the data of peripheral blood uric acid and clinical data in 50 patients with HCC and analyzed the relationship with prognosis. At the same time, the transcriptome sequencing data of TCGA and GEO databases were collected to analyze the changes in purine metabolic pathway activity and construct a prognosis prediction model. Based on the prognosis prediction model related to purine metabolism, we further looked for the differences in the immune microenvironment and molecular level and provided possible drug targets.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> We found that the level of serum uric acid was positively correlated with the prognosis of HCC. At the same time, purine metabolism and purine biosynthesis pathway activities were significantly activated in patients with a poor prognosis of HCC. The prognosis prediction model of HCC based on purine metabolism and purine biosynthesis pathway can accurately evaluate the prognosis of patients with HCC. Meanwhile, we found that there were significant changes in tumor immune infiltration microenvironment and biological function at the molecular level in patients with over-activation of purine metabolism and purine biosynthesis pathway. In addition, we found that uric acid level was positively correlated with peripheral blood leukocytes in HCC patients.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> In this study, we found that the level of peripheral blood uric acid in patients with HCC is correlated with their prognosis. The prognosis of patients with HCC can be accurately predicted through the metabolic process of uric acid and purine.<\/jats:p>","DOI":"10.3389\/fgene.2022.942267","type":"journal-article","created":{"date-parts":[[2022,7,12]],"date-time":"2022-07-12T09:11:50Z","timestamp":1657617110000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["A Novel Purine and Uric Metabolism Signature Predicting the Prognosis of Hepatocellular Carcinoma"],"prefix":"10.3389","volume":"13","author":[{"given":"Shengjie","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Baoying","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weijuan","family":"Tan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu","family":"Qi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao","family":"Ma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinghe","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,7,12]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"112543","DOI":"10.1016\/j.msec.2021.112543","article-title":"Photodynamic and Antiangiogenic Activities of Parietin Liposomes in Triple Negative Breast Cancer","volume":"134","author":"Ayoub","year":"2022","journal-title":"Biomater.
