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...

Approximately 50% hepatocellular carcinoma patients meeting the Milan criteria utilized to develop an improved prognostic model for predicting the recurrence in these patients. Using univariate and multivariate analysis, cytokeratin-19 and glypican-3 expression patterns, tumor number and histological grading from eight putative prognostic factors comprised the risk factor scoring model to predict the tumor recurrence. In the training cohort, the area under roc curve (AUC) value of the model was 0.715 [95% confidence interval (CI) = 0...

Low molecular weight heparin (LMWH), the guideline based drug for prophylaxis and treatment of cancer-associated thrombosis, was recently shown to sensitize cisplatin resistant A2780cis human ovarian cancer cells for cisplatin cytotoxicity upon 24 h pretreatment with 50 μg × mL-1 of the LMWH tinzaparin in vitro, equivalent to a therapeutic dosage. Thereby, LMWH induced sensitization by transcriptional reprogramming of A2780cis cells via not yet elucidated mechanisms that depend on cellular proteoglycans. Here we aim to illuminate the underlying molecular mechanisms of LMWH in sensitizing A2780cis cells for cisplatin...

Nitric oxide (NO) is a regulatory molecule in the vascular system and its inhibition due to endothelial injury contributes to cardiovascular disease. The glycocalyx is a thin layer of glycolipids, glycoproteins, and proteoglycans on the surface of mammalian epithelial cells. Extracellular forces are transmitted through the glycocalyx to initiate intracellular signaling pathways. In endothelial cells (ECs), previous studies have shown the glycocalyx to be a significant mediator of NO production; degradation of the endothelial glycocalyx layer (EGL) drastically reduces EC production of NO in response to fluid shear stress...

Peripheral ischemia as a result of occlusive vascular disease is a widespread problem in patients over the age of 65. Angiogenic therapies that can induce microvascular growth have great potential for providing a long lasting solution for patients with ischemia and would provide and an appealing alternative to surgical and percutaneous interventions. However, many angiogenic therapies have seen poor efficacy in clinical trials, suggesting that patients with long term peripheral ischemia have considerable therapeutic resistance to angiogenic stimuli...

Autosomal-recessive omodysplasia (OMOD1) is a genetic condition characterized by short stature, shortened limbs, and facial dysmorphism. OMOD1 is caused by loss-of-function mutations of glypican 6 (GPC6). In this study, we show that GPC6-null embryos display most of the abnormalities found in OMOD1 patients and that Hedgehog (Hh) signaling is significantly reduced in the long bones of these embryos. The Hh-stimulatory activity of GPC6 was also observed in cultured cells, where this GPC increased the binding of Hh to Patched 1 (Ptc1)...

Advances in molecular biology and nanomedicine based therapies hold promise to obviate the need of multiple surgical interventions (associated with current management) in craniosynostosis by preventing bone re-ossification. One such adjunctive therapy involves application of glypicans 1 and 3 (GPC1 and GPC3) that are BMP inhibitors implicated in downregulating the BMP2 activity in prematurely fusing sutures. Electrochemically anodized Titania nanotube (TNT) arrays have been recognized as a promising localized, long-term drug delivery platform for bone-related therapies...

Liver cancer is the second leading cause of cancer-related deaths, and hepatocellular carcinoma (HCC) is the most common type. Therefore, molecular targets are urgently required for the early detection of HCC and the development of novel therapeutic approaches. Glypican-3 (GPC3), an oncofetal proteoglycan anchored to the cell membrane, is normally detected in the fetal liver but not in the healthy adult liver. However, in HCC patients, GPC3 is overexpressed at both the gene and protein levels, and its expression predicts a poor prognosis...

The global burden of hepatocellular carcinoma is increasing; actually, it is estimated as 750,000 new cases annually. This study was initiated to emphasize the possibility that gallic acid could alleviate hepatocarcinogenesis in vivo. In this study, 40 rats were enrolled and distributed as follows; group 1 was set as negative control, while all of groups 2, 3, and 4 were orally received N-nitrosodiethylamine for hepatocellular carcinoma induction. Group 2 was left untreated, whereas groups 3 and 4 were orally treated with gallic acid and doxorubicin, respectively...

REVIEW

The current dogma in neural regeneration research implies that chondroitin sulfate proteoglycans (CSPGs) inhibit plasticity and regeneration in the adult central nervous system (CNS). We argue that the role of the CSPGs can be reversed from inhibition to activation by developmentally expressed CSPG-binding factors. Heparin-binding growth-associated molecule (HB-GAM; also designated as pleiotrophin) has been studied as a candidate molecule that might modulate the role of CSPG matrices in plasticity and regeneration...

We present a case of primary hepatic choriocarcinoma in an 83-year-old Japanese woman with gastric wall and lymph node metastases and a splenic vein tumor thrombus. Multiple irregular hepatic tumors with massive necrosis and hemorrhage were observed during autopsy. Syncytiotrophoblast-like and mononucleated cytotrophoblast-like cell morphology with focal hepatocellular carcinoma (HCC)-like trabecular structures was observed. In immunohistochemical analyses, the tumor cells expressed human chorionic gonadotropin (hCG) and cytokeratins (AE1/AE3, CK7, CK19) but were negative for alpha-fetoprotein (AFP), glypican-3, and vimentin...

OBJECTIVE: Glioblastoma (GBM) relapses locally or in a disseminated pattern, and is highly resistant to chemo-radiotherapy. Although dissemination is associated with poor prognosis for GBM patients, the clinico-pathological factors that promote dissemination have not been elucidated. Glypican-1 (GPC-1) is a heparin sulfate proteoglycan that is attached to the extracytoplasmic surface of the cell membrane and regulates cell motility. The aim of this study was to determine whether GPC-1 expression correlated with GBM dissemination and patient prognosis...

BACKGROUND Simpson-Golabi-Behmel syndrome (SGBS) is a rare X-linked recessive syndrome characterized by fetal overgrowth. CASE REPORT We present a case of a male infant with SGBS. Abnormal prenatal ultrasound (including congenital diaphragmatic hernia) prompted microarray testing of amniotic fluid cells, which showed deletion on chromosome Xq26.2 affecting the glypican-3 gene consistent with SGBS type I. The infant died six hours after birth and at autopsy showed features of SGBS, including macrosomia, organomegaly, diaphragmatic hernia with consequent pulmonary hypoplasia, cleft palate, large tongue with a midline groove, a supernumerary nipple, Meckel's diverticulum, and abnormal phalanges...
