Beyond Antibodies: Glypican-3-Targeting Peptides for Precision Hepatocellular Carcinoma Theranostics.
Glypican-3 (GPC-3) is a cell-surface glycoprotein, highly expressed in hepatocellular carcinoma (HCC) but largely absent in normal adult liver tissues, making it a clinically compelling biomarker and therapeutic target. Although monoclonal antibodies and antibody-drug conjugates have proven to be GPC-3-targeted therapi...
