Glioma is an extremely aggressive and lethal form of brain cancer. Despite recent advances in diagnostics and treatments, prognosis for advanced patients suffering from these diseases remains poor. Therefore, identification of new therapeutic targets for glioma is of significant importance. In this study, we identified the important role of Smad ...

Human anal canal squamous cell carcinoma (SCC) cell line has not yet been reported due to the rarity of this disease. Since cell lines to study this malignancy were not available, we attempted to establish and characterize anal canal SCC cell line from primary culture of lymph node metastasis. Six ...

A correlation between cancer and hypercoagulability has been described for more than a century. Patients with cancer are at increased risk for thrombotic complications, and the clotting initiator protein, tissue factor (TF), is possibly involved in this process. In addition to TF, the presence of negatively charged phospholipids, particularly phosphatidylserine ...

Several human cancers have been found to contain cancer stem-like cells (CSCs) having cancer-initiating ability. However, only a few reports have shown the existence of CSCs in bone and soft tissue sarcomas. In this study, we identified and characterised side population (SP) cells that showed drug-resistant features in human bone ...

The Coxsackie and adenovirus receptor (CAR) has been shown to inhibit cancer cell proliferation, migration, and invasion. The underlying mechanisms, however, are poorly understood. The differential gene expression in the human colon cancer cell line DLD1 on RNAi-mediated functional CAR knockdown was analysed using oligo-array technology. Expression of alpha-catenin was ...

Jerdonitin is a P-II class snake venom metalloproteinase comprising metalloproteinase and disintegrin domains. In this study, we established a high-level expression system in Pichia pastoris and developed a purification strategy for the recombinant Jerdonitin. This recombinant Jerdonitin degraded fibrinogen at a level of activity comparable with its wild type. The ...

The effect of citrus pectin (CP) on the proliferative capacity of four malignant cell lines was examined. Various dose of CP inhibited the proliferation of two-colon carcinoma and an erythroleukemia cell lines. Raji cells were not affected at all. The three lines affected by CP are known to express galectins ...

We have previously described that antibodies and T cells against myelin basic protein (MBP) rose under conditions to induce acute experimental autoimmune encephalomyelitis (EAE) bind other proteins present in the synaptosomal fraction, some of them identified as synapsin I. The aim of this study was to evaluate whether anti-MBP T-cell ...

AIM: Recent literature suggests that some human cancer cell lines possess a calcium cation receptor. Human myeloma cell lines have demonstrated stimulated cell proliferation by the gadolinium cation through this receptor, and osteosarcoma cell lines possess the same cation receptor. Although enhanced MRI is a very useful diagnostic tool for ...

The cancer stem cell (CSC) model, in which a small population of cells within a tumor possesses the ability to self-renew and reconstitute the phenotype of primary tumor, has gained wide acceptance based on evidence over the past decade. It has also been reported that cancer cell lines contain a ...

Arginase 1 (ARG1) inhibits T-cell proliferation by degrading extracellular arginine, which results in decreased responsiveness of T cells to CD3/TCR stimulation. In humans, ARG1 is stored in inactive form within granules of polymorphonuclear neutrophils (PMNs) and gets activated on release. We studied the role of PMNs-related ARG1 activity in nonsmall ...

Direct reprogramming of human somatic cells into pluripotency has broad implications in generating patient-specific induced pluripotent stem (iPS) cells for disease modeling and cellular replacement therapies. However, the low efficiency and safety issues associated with generation of human iPS cells have limited their usage in clinical settings. Cell types can ...

The prognosis of glioblastoma (GBM) remains poor. Diffuse invasion of distant brain tissue by migrating cells from the primary tumour mass has already occurred at time of diagnosis. Anti-cancer effects of a selective sigma-1 agonist, 4-(N-benzylpiperidin-4-yl)-4-iodobenzamide (4-IBP), in glioblastoma were shown previously, leading to the present work where the effects ...

CD26 is a multifunctional membrane-bound glycoprotein that regulates tumour growth in addition to its other activities. Because disease aggressiveness is correlated with CD26 expression in several T-cell malignancies, we decided to investigate the invasiveness of cells expressing different levels of CD26. To assess CD26 involvement in cell invasion, we performed ...

Immortalized cell lines, such as human cancer cell lines, are an indispensable experimental resource for many types of biological and medical research. However, unless the cell line has been authenticated prior to use, interpretation of experimental results may be problematic. The potential problems this may cause are illustrated by studies ...

A controversy has arisen over the past several years about the true origin of the human MDA-MB-435 cell line. Originally described as a human breast cancer cell line, subsequent expression array studies instead suggested a gene expression profile consistent with a melanoma origin. Subsequent karyotype and comparative genomic hybridization studies ...

A new cell line from the neonate larvae of Aedes aegypti (L) mosquito was established and characterized. The cell line at the 50th passage (P) level consisted of three prominent cell types, i.e., epithelial-like cells (92%), fibroblast-like cells (7%), and giant cells ( approximately 1%). Karyological analysis showed diploid (2n ...

OBJECTIVES: In the light of recent advances in tumor biology and genetics, we hypothesized that tibolone, an estrogen receptor agonist, may have antiproliferative effects on primary human glioblastoma cells and rat C6 malignant glioma cell lines. We thought that tibolone should exert its antiproliferative effects by augmenting glial cell differentiation ...

Small cell lung cancer (SCLC) shows an excellent sensitivity to chemotherapy, but commonly develops resistance after a few months. An early identification of a genomic marker in drug discovery may help to select patients who would respond to treatment in clinical trials. Herein, we characterized the parental NCI-H69 (sensitive) and ...

A new adenine-substituted bromotyrosine-derived metabolite designated as aphrocallistin (1) has been isolated from the deep-water Hexactinellida sponge Aphrocallistes beatrix. Its structure was elucidated on the basis of spectral data and confirmed through a convergent, modular total synthetic route that is amenable toward future analogue preparation. Aphrocallistin inhibits the growth of ...

Significant information on reproductive function has been generated based on the rat model, including many seminal discoveries. Yet little is known about the molecular and cellular events involved in control of reproductive function, mainly due to the pervasive lack of cell models from rat. We have therefore generated a wide ...

Fibroblast growth factor receptors (FGFR) play key roles in proliferation, differentiation, and tumorigenesis. Many urothelial carcinomas contain activating point mutations or increased expression of FGFR3. However, little is known about the role of other FGFRs. We examined FGFR expression in telomerase-immortalized normal human urothelial cells, urothelial carcinoma cell lines, and ...

Recent studies showed that glioma conditioned medium is able to induce blood-brain barrier properties in in vitro models. In this regard, it was investigated whether glioma conditioned medium can also influence the lectin-binding capacity of blood-brain barrier in vitro models. For the presented study cell lines PBMEC/C1-2 and ECV304 were ...

CD133+ populations of human glioblastoma multiforme (GBM) cells are reportedly enriched for tumor stem cells (TSCs) or tumor-initiating cells (TICs). Approximately 40% of freshly isolated GBM specimens, however, do not contain CD133+ tumor cells, raising the possibility that CD133 may not be a universal enrichment marker for GBM TSCs/TICs. Here ...

Changes in proteoglycan and glycosaminoglycan (GAG) content and distribution may play an important role in the development of many diseases, atherosclerosis, cancer and diabetes. Human cell lines act as models for the underlying pathomechanisms. Despite the importance of proteoglycans for cell functioning, information on the GAG composition of most human ...
