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...

Ovarian Sertoli-Leydig cell tumors (SLCTs) are uncommon neoplasms that are occasionally associated with an elevated level of serum alpha fetoprotein (AFP), a marker of germ cell neoplasms, particularly yolk sac tumor (YST). We report 7 cases of ovarian SLCT (3 moderately differentiated, 2 poorly differentiated, 2 retiform) with heterologous intestinal-type glands, 6 of which were associated with elevated serum AFP. The intestinal-type mucinous glands were immunoreactive for SALL4 (4 cases), AFP (4 cases), glypican 3 (1 case), CDX2 (6 cases), and villin (7 cases), markers that are commonly expressed in YSTs, although the latter 2 markers would be expected to be positive in intestinal-type glands...

AIMS: Accurate histologic diagnosis and classification of germ cell tumors (GCTs) is key to informing successful therapeutic and surveillance strategy. Modern therapeutic approach for yolk sac tumor (YST) is highly curative. Because YST takes on a large morphologic spectrum, it can be confused for other GCT subtypes as well as somatic carcinomas, particularly when YST presents in an extragonadal or a metastatic setting. Currently available immunohistochemical markers are limited by suboptimal sensitivity and specificity...

Heparan sulfates are linear polysaccharides with complex modification patterns, which are covalently bound via conserved attachment sites to core proteins to form heparan sulfate proteoglycans (HSPGs). HSPGs regulate many aspects of the development and function of the nervous system, including cell migration, morphology, and network connectivity. HSPGs function as co-factors for multiple signaling pathways, including the Wnt signaling molecules and their Frizzled receptors. To investigate the functional interactions among the HSPG and Wnt networks, we conducted genetic analyses of each, and also between these networks using five cellular migrations in the nematode Caenorhabditis elegans We find that HSPG core proteins act genetically in a combinatorial fashion dependent on the cellular contexts...

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...

Cell surface proteoglycans comprise a transmembrane or membrane-associated core protein to which one or more glycosaminoglycan chains are covalently attached. They are ubiquitous receptors on nearly all animal cell surfaces. In mammals, the cell surface proteoglycans include the six glypicans, CD44, NG2 (CSPG4), neuropilin-1 and four syndecans. A single syndecan is present in invertebrates such as nematodes and insects. Uniquely, syndecans are receptors for many classes of proteins that can bind to the heparan sulphate chains present on syndecan core proteins...

Hepatocellular carcinoma (HCC) is a cause of several deaths related to cancer worldwidely. In early stage, curative treatments such as surgical resection, liver transplant and local ablation can improve the patient ´s survival. However, the disease is detected in advanced stage; moreover some available therapies are restricted to palliative care and local treatment. Early detections of HCC and adequate therapy are crucial to increase survival as well as to improve the patient´s quality of life. Therefore, researchers have been investigating molecular biomarkers with high sensibility and reliability as Golgi 73 protein (GP73), Glypican-3 (GPC3), Osteopontin (OPN), microRNAs and others...
