Glypican-3 is a protein that in humans is encoded by the GPC3 gene.[1][2][3][4] The GPC3 gene is located on human X chromosome (Xq26) where the most common gene (Isoform 2, GenBank Accession No.: NP_004475) encodes a 70-kDa core protein with 580 amino acids.[5] Three variants have been detected that encode alternatively spliced forms termed Isoforms 1 (NP_001158089), Isoform 3 (NP_001158090) and Isoform 4 (NP_001158091).[5]
Structure and function
The protein core of GPC3 consists of two subunits, where the N-terminal subunit has a size of ~40 kDa and the C-terminal subunit is ~30 kDa.[5] Six glypicans (GPC1-6) have been identified in mammals. Cell surface heparan sulfate proteoglycans are composed of a membrane-associated protein core substituted with a variable number of heparan sulfate chains. Members of the glypican-related integral membrane proteoglycan family (GRIPS) contain a core protein anchored to the cytoplasmic membrane via a glycosyl phosphatidylinositol linkage. These proteins may play a role in the control of cell division and growth regulation.[3] GPC3 interacts with both Wnt and frizzled (FZD) to form a complex and triggers downstream signaling.[6] A biochemical study has revealed that Wnt recognizes a heparan sulfate structure on GPC3 containing IdoA2S and GlcNS6S, and that the 3-O-sulfation in GlcNS6S3S significantly enhances the binding of Wnt to the glypican.[7]
Disease linkage
Deletion mutations in this gene are associated with Simpson-Golabi-Behmel syndrome.[8]
Diagnostic utility
Glypican 3 immunostaining has utility for differentiating hepatocellular carcinoma (HCC) and dysplastic changes in cirrhotic livers; HCC stains with glypican 3, while liver with dysplastic changes and/or cirrhotic changes does not.[9] Using the YP7 murine monoclonal antibody, GPC3 protein expression is found in HCC, not in cholangiocarcinoma.[10] The YP7 murine antibody has been humanized and named as 'hYP7'. [11] GPC3 is also expressed to a lesser degree in melanoma, ovarian clear-cell carcinomas, yolk sac tumors, neuroblastoma, hepatoblastoma, Wilms' tumor cells, and other tumors.[5] However, the significance of GPC3 as a diagnostic tool for human tumors other than HCC is unclear.
Therapeutic potential
Glypican 3 is a potential therapeutic target for treating liver cancer and other cancers.[5][6] Several therapeutic anti-GPC3 antibodies have been developed. Humanized monoclonal antibodies (GC33,[12] hYP7[10] ) recognize the C-lobe of GPC3. The laboratory of Dr. Mitchell Ho at the National Cancer Institute reported the human single-domain antibody HN3[13] targeting the N-lobe of GPC3 and the human monoclonal antibody HS20[14][15] targeting the heparan sulfate chains of GPC3 by phage display technology. Both HN3 and HS20 antibodies inhibit Wnt signaling in liver cancer cells . The immunotoxins based on HN3 [16][17] and antibody-drug conjugates based on hYP7 [18] have been developed for treating liver cancer.
