RBM27 expression was assessed in HCC tissues\/cell lines. Knockdown models (lentiviral shRNA) evaluated impacts on proliferation, migration, invasion (Transwell\/wound healing), and tumor growth (xenografts).

Genomic analysis revealed that this upregulation is driven by copy number variations (CNVs), particularly gene amplification, alongside specific mutational patterns. This abnormal upregulation was closely correlated with advanced clinical stages of the disease, elevated AFP, and poor survival (OS\/DSS\/PFI;\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.05). RBM27 knockdown suppressed HCC proliferation, migration, invasion, and xenograft growth. Mechanistically, RBM27 activated oxidative phosphorylation, driving immunosuppression via CD8+ T cell and NK cell depletion, Treg\/Th2 enrichment, and impaired cancer\u2010immunity cycle steps.
