The abnormal expression of β-1,4-N-acetyl-galactosaminyltransferase 1 (B4GALNT1) seemed to be implicated in tumorigenesis. Nonetheless, this enzyme's roles in HCC are unclear.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>By analyzing the TCGA_LIHC, GSE77509, and GSE135631 datasets, the levels of <i>B4GALNT1</i> expression in HCC and surrounding non-cancerous tissues were compared. The prognostic implications of <i>B4GALNT1</i> were assessed using the Cox regression analysis (CRA). The relationship of <i>B4GALNT1</i> mutations with CpG island methylation levels and prognosis was examined by analyzing the cBioPortal and MethSurv databases. We sifted the evidence of <i>B4GALNT1</i> expression correlating with 28 immune cell types' infiltration by harnessing the “GSVA” R package. To delve into the influences of genes associated with B4GALNT1 on HCC, we implemented gene set enrichment analysis (GSEA). We constructed a lentiviral vector expressing B4GALNT1 and knocked down <i>B4GALNT1</i> in HepG2 cells. The resulting effects on HCC cell proliferation and apoptosis were analyzed via cell proliferation assays and flow cytometry.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>HCC tissues presented significant <i>B4GALNT1</i> overexpression relative to surrounding non-cancerous tissues, marking it as a standalone risk factor for HCC progression.
