Core Tip
Core Tip: Osteopontin (OPN) drives gastrointestinal tumor progression by activating the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway, promoting proliferation, metastasis, chemoresistance, and immune evasion. Key mechanisms involve upregulating anti-apoptotic proteins (e.g., B-cell lymphoma 2), inducing epithelial-mesenchymal transition via Snail/Twist, and remodeling the tumor microenvironment through VEGF-driven angiogenesis and cluster of differentiation 44-mediated immune suppression. Targeting this axis with PI3K/AKT inhibitors (e.g., Alpelisib) or OPN-neutralizing antibodies may reverse drug resistance and suppress metastasis. Challenges include pathway redundancy and the need for biomarker-guided precision strategies. Future research should focus on OPN isoform specificity, combination therapies (e.g., with immune checkpoint inhibitors), and multi-omics approaches to optimize outcomes in refractory cancers.
