In this study, we performed an integrative multiomics analysis to identify genome stability\u2013associated candidates in HCC and experimentally evaluated the functional relevance of CENPA. By intersecting genome stability\u2013related genes with differentially expressed and survival\u2010associated genes in TCGA\u2010LIHC, we identified a candidate gene set enriched in mitotic regulation, DNA maintenance, and cell\u2010cycle pathways. A LASSO Cox model was then constructed to derive a 10\u2010gene prognostic signature. Among these genes, CENPA was selected for focused analysis because of its contribution to the model and its established role in centromere identity and chromosome segregation. CENPA was significantly upregulated in HCC tissues, associated with advanced clinicopathological features, and correlated with unfavorable survival outcomes. Copy\u2010number and cell\u2010cycle analyses further linked high CENPA expression to proliferative and genome instability\u2013related molecular states. Functional\u2010state scoring showed strong associations between CENPA expression and cell\u2010cycle activity, DNA repair, and DNA damage\u2013related programs. In vitro, CENPA knockdown suppressed HCC cell proliferation, clonogenic growth, and migration. Moreover, CENPA depletion increased cisplatin sensitivity, reduced IC50 values, and induced G2\/M accumulation in HCC cell line models. Collectively, these findings suggest that CENPA is a genome stability\u2013associated biomarker and functional contributor to malignant phenotypes in HCC. The cisplatin\u2010related results further indicate a potential association between CENPA\u2010dependent mitotic regulation and genotoxic stress response, although in vivo and clinical validation are required to determine its translational significance.<\/jats:p>","DOI":"10.1155\/humu\/9292971","type":"journal-article","created":{"date-parts":[[2026,5,26]],"date-time":"2026-05-26T06:18:17Z","timestamp":1779776297000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["CENPA
