A three-gene MTRG prognostic signature was developed through univariate and LASSO-Cox regression, and validated using Kaplan\u2013Meier analysis, time-dependent ROC curves, and calibration plots. Functional enrichment, immune infiltration, tumor mutational burden, and immunotherapy response was predicted using the Tumor Immune Dysfunction and Exclusion (TIDE) algorithm. Single-cell and spatial transcriptomics were used to investigate the mechanistic role of CFL1 in tumor-stroma crosstalk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The signature (CFL1, CRTC2, SRGAP2) stratified HCC patients into high- and low-risk groups with distinct overall survival (OS). High-risk tumors showed coordinated activation of MT and ECM-remodeling pathways alongside an immunosuppressive microenvironment. In silico analyses suggested that CFL1-high tumor cells may transmit MDK signals to fibroblasts (via SDC2, NCL, and ITGA4\u2013ITGB1) and to T cells (via NCL). Spatial transcriptomics confirmed predominant CFL1 enrichment in stromal compartments. The signature was an independent prognostic factor, and the nomogram showed promising clinical utility.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This three-gene MTRG-associated signature is associated with predicted immunotherapy response based on computational analysis in HCC.
