Silencing of PIGU inhibits the progression of esophageal squamous cell carcinoma through the PI3K/AKT signaling pathway.

ABSTRACT: Phosphatidylinositol glycan anchor biosynthesis class U (PIGU), a crucial subunit of the glycosylphosphatidylinositol transamidase (GPI-T) complex, is an oncogene in hepatocellular carcinoma. However, its role in esophageal squamous cell carcinoma (ESCC) remains poorly understood. This study aims to clarify PIGU's role and mechanisms in ESCC by analyzing its expression across pan-cancer datasets, clinical relevance in TCGA-ESCA samples, and effects on cell behavior (migration, invasion, proliferation) and signaling pathways, validated via immunohistochemistry. To examine cell behavior, we used Transwell, colony-formation, CCK-8, and wound-healing assays to assess migration, invasion, proliferation, and wound healing.The epithelial-mesenchymal transition marker levels were measured using We
