The molecular basis of pancreatic cancer is not understood. Previous attempts to determine the specific genes expressed in pancreatic cancer have been hampered by similarities between adenocarcinoma and chronic pancreatitis. In the current study, microarrays (Affymetrix) were used to profile gene expression in pancreatic adenocarcinoma (10), pancreatic cancer cell lines (7), chronic pancreatiti...

Research in Barrett's oesophagus, and neoplastic progression to OAC (oesophageal adenocarcinoma), is hobbled by the lack of good pre-clinical models that capture the evolutionary dynamics of Barrett's cell populations. Current models trade off tractability for realism. Computational models are perhaps the most tractable and can be used both to interpret data and to develop intuitions and hypoth...

The high mobility group (HMG) proteins I and Y are well characterized nonhistone chromosomal proteins which bind to A.T-rich regions of DNA, and may regulate gene expression and/or DNA replication. We utilized a series of mouse mammary epithelial preneoplastic and tumor cell lines to explore the relationship between neoplastic transformation and HMG-I(Y) gene expression. The cell lines used in ...

Herpes-type viruses recovered from established cell lines were coated by homologous rabbit antisera as visualized by electron microscopy. These chronically infected cell lines were derived from malignant human tissues. Cross reaction was detected among the herpes-type viruses iso lated from African and American patients afflicted with neoplastic disorders. This group of viruses are not related ...

objective(s): artemisia is a genus of herbs and small shrubs forms an important part of natural vegetation in iran. it has been reported that several artemisia species possess anti-proliferative effects. considering the value of this genus in anti-cancer researches we have chosen artemisia biennis for cytotoxic and mechanistic studies. materials and methods:in this study we have investigated th...

The IL-12Rbeta2 gene is expressed in human mature B cell subsets but not in transformed B cell lines. Silencing of this gene may be advantageous to neoplastic B cells. Our objective was to investigate the mechanism(s) and the functional consequence(s) of IL-12Rbeta2 gene silencing in primary B cell tumors and transformed B cell lines. Purified tumor cells from 41 patients with different chronic...

Background Lafoensia pacari is a native species from South America which has been used in traditional medicine as antiulcerogenic and anti-inflammatory for several diseases, but the antineoplastic potential still have not been elucidated so far, though its etnopharmacological indication. The aim of this study was to evaluate the anti-neoplastic effect of L. pacari ethanolic extract in three hum...

is currently used in the treatment of various neoplastic and non-neoplastic diseases such as cancer, sickle cell anemia and HIV (1). Derivatives of hydroxyurea were found to inhibit matrix zinc metaloproteinases (MMP), urease, carboanhydrase, carboxypeptidase, cyclooxygenase and 5-lipooxygenase. Early experiments on antibacterial properties and effects on tumor cell lines of hydroxyurea and low...
