Hepatocellular carcinoma with neuroendocrine differentiation, where tumor cells stain for both hepatocellular and neuroendocrine markers, is extremely rare. We report a case of a 65-year-old man who presented with a 14-cm rapidly growing mass in the right lobe of his liver with local extension into the gallbladder and portal vein. Serum AFP was 4625ng/mL. Liver biopsy showed a poorly differentiated neoplasm with cells showing nuclear pleomorphism, high nuclear/cytoplasmic ratio, and numerous mitoses. The tumor cells stain for AFP, glutamine synthase, arginase, and glypican-3...

It has been suggested that hepatobiliary carcinomas are less frequent in Wilson's disease (WD) than in liver diseases of other etiology. However, the protective role of copper against malignancies is debated. Only a few cases of cholangiocarcinoma (CCC) in WD have been published. Here we report on a case of a 47-year-old male H1069Q homozygous, Kayser-Fleischer ring positive WD patient with a low ceruloplasmin level who was followed up and treated with chelating agents throughout nine years. The patient presented with neurological symptoms and liver cirrhosis at diagnosis...

Ascorbate-induced release of heparan sulfate from S-nitrosylated heparan sulfate proteoglycan glypican-1 takes place in endosomes. Heparan sulfate penetrates the membrane and is transported to the nucleus. This process is dependent on copper and on expression and processing of the amyloid precursor protein. It remains unclear how exogenously supplied ascorbate can generate HS-anMan in endosomes and how passage through the membrane is facilitated. Here we have examined wild-type, Alzheimer Tg2576 and amyloid precursor protein (-/-) mouse fibroblasts and human fetal and Niemann-Pick C1 fibroblasts by using deconvolution immunofluorescence microscopy, siRNA technology and [S(35)]sulfate-labeling, vesicle isolation and gel chromatography...

Glypican 5 (GPC5) belongs to the family of heparan sulfate proteoglycans (HSPGs). It was initially known as a regulatorof growth factors and morphogens. Recently, there have been reports on its correlation with the tumorigenic process in the development of some cancers. However, little is known about its precise role in prostate cancer (PCa). In the present study, we explored the expression pattern and biological functions of GPC5 in PCa cells. Our results showed that GPC5 was lowly expressed in PCa cell lines...

There are limited strategies for the treatment of hepatocellular carcinoma (HCC). In this study, we prepared a Bispecific T cell engager (BiTE) targeting Glypican 3 (GPC3) and CD3. The GPC3/CD3 BiTE was prepared by fusing the single-chain variable fragment (scFv) of the humanized anti-GPC3 antibody (9F2) with the scFv of the anti-CD3 antibody (OKT3). The in vitro and in vivo cytotoxic activities of the GPC3/CD3 BiTE were evaluated against various HCC cell lines. The GPC3/CD3 BiTE could efficiently mediate the T cell killing of GPC3-positive HCC in vitro, which was dependent on GPC3 expression on the surface of HCC cells...

BACKGROUND: Alpha-fetoprotein (AFP) and Glypican 3 (GPC3) are both oncogenes and reactivated in hepatocellular carcinoma (HCC). PreS2 has been proved to be an important transactivator in HCC. In this study, we aim to provide evidence that HBV protein preS2 is responsible for AFP and GPC3's reactivation in HCC. METHODS: Totally Sixty-three cases of HCC, aged 34-79, who were surgically treated and pathologically confirmed were enrolled. The levels of AFP in peripheral serum were detected with electrochemical luminescence method before surgery...

Hepatocellular carcinoma (HCC) has a high morbidity and mortality rate worldwide, with limited treatment options. Glypican-3 (GPC3) is a glycosylphosphatidylinositol-anchored glycoprotein that is overexpressed in most HCC tissues but not in normal tissues. GPC3-targeting antibody therapy shows limited response in a clinical trial due to the lack of a tumor-specific cytotoxic T lymphocyte (CTL) response. Here, in C57/B6 mice, we demonstrated that intravenous infusion of GPC3-coupled lymphocytes (LC/GPC3(+)) elicited robust GPC3-specific antibody and CTL responses, which effectively restricted proliferation and lysed cultured-HCC cells...

The outcome for advanced stage hepatocellular carcinoma (HCC) remains poor, highlighting the need for novel therapies. Genetically modified mesenchymal stem cells (MSCs) are actively being explored as cancer therapeutics due to their inherent ability to migrate to tumor sites. We reasoned that MSCs can be genetically modified to redirect T cells to Glypican-3 (GPC3)(+) HCC, and genetically modified these with viral vectors encoding a GPC3/CD3 bispecific T cell engager (GPC3-ENG), a bispecifc T cell engager specific for an irrelevant antigen (EGFRvIII), and/or costimulatory molecules (CD80 and 41BBL)...

Glypican-3 (GPC3) is a promising new marker for hepatocellular carcinoma, but the reported values for serum GPC3 differ markedly between currently available kits. Here we isolated Affimer non-antibody binding proteins against GPC3 by phage display and developed a new sandwich chemiluminescence immunoassay (CLIA) combining an Affimer with a monoclonal antibody (Affimer-MAb CLIA). The proposed CLIA assay demonstrated a wide linear range  0.03-600 ng/mL) with a good linear correlation coefficient (0.9999), a high detection limitation (0...

RATIONALE: Hepatocellular carcinoma (HCC) is known to grow in a mosaic pattern, and it can sometimes be combined with non-hepatocellular cells. Despites the variety of combination, HCC with a significant neuroendocrine carcinoma (NEC) component remains very rare. Most of the reported cases were treated as conventional HCC with a relatively poor prognosis. Early diagnosis may lead to a better treatment modality. Here, we report a case of composite HCC and small cell carcinoma (SCC) with nodal metastasis of the SCC component alone...

Morphogens regulate tissue patterning through their distribution in concentration gradients. Emerging research establishes a role for specialized signalling filopodia, or cytonemes, in morphogen dispersion and signalling. Previously we demonstrated that Hedgehog (Hh) morphogen is transported via vesicles along cytonemes emanating from signal-producing cells to form a gradient in Drosophila epithelia. However, the mechanisms for signal reception and transfer are still undefined. Here, we demonstrate that cytonemes protruding from Hh-receiving cells contribute to Hh gradient formation...

Craniosynostosis is a complex disease condition, which involves premature fusion of cranial vault sutures and lacks desirable treatment. Previous studies have demonstrated decreased proliferation rate of osteoblasts and downregulated expression of glypican 3 (GPC3) in syndromic craniosynostosis patients. In this study, quantitative and qualitative analysis were utilized to assess the effect of GPC3 in human fetal osteoblastic cell line, hFOB 1.19. Lentiviral transfection efficiency with green fluorescent protein images was obtained after 72 hours...

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is a major cause of cancer-related death worldwide. Previously, we demonstrated that glypican-3 (GPC3) is highly expressed in HCC, and that GPC3 induces oncogenicity and promotes the growth of cancer cells through IGF-1 receptor (IGF-1R). In the present study, we investigated the mechanisms of GPC3-mediated enhancement of IGF-1R signaling. We demonstrated that GPC3 decreased IGF-1-induced IGF-1R ubiquitination and degradation and increased c-Myc protein levels...
