Different glycosylation of cadherins from human bladder non-malignant and cancer cell lines.

Project description:BACKGROUND:The aim of the present study was to determine whether stage of invasiveness of bladder cancer cell lines contributes to alterations in glycan pattern of their cadherins. RESULTS:Human non-malignant epithelial cell of ureter HCV29, v-raf transfected HCV29 line (BC3726) and transitional cell cancers of urine bladder Hu456 and T24 were grown in cell culture. Equal amounts of protein from each cell extracts were separated by SDS-PAGE electrophoresis and were blotted on an Immobilon P membrane. Cadherins were immunodetected using anti-pan cadherin mAb and lectin blotting assays were performed, in parallel. N-oligosaccharides were analysed by specific reaction with Galanthus nivalis agglutinin (GNA), Sambucus nigra agglutinin (SNA), Maackia amurensis agglutinin (MAA), Datura stramonium agglutinin (DSA), Aleuria aurantia agglutinin (AAA), Phaseolus vulgaris agglutinin (PHA-L) and wheat germ agglutinin (WGA). The cadherin from HCV29 cell line possessed bi- and/or 2,4-branched triantennary complex type glycans, some of which were alpha2,6-sialylated. The cadherin from BC3726 cell line exhibited exclusively high mannose type glycans. Cadherins from Hu456 and T24 cell lines expressed high mannose type glycans as well as beta1,6-branched oligosaccharides with poly-N-acetyllactosamine structures and alpha2,3-linked sialic acid residues. Additionally, the presence of fucose and alpha2,6-sialic acid residues on the cadherin from T24 cell line was detected. CONCLUSIONS:These results indicate that N-glycosylation pattern of cadherin from bladder cancer cell line undergoes modification during carcinogenesis.

Expression data from pancreatic cancer cell lines

Project description:Expression data from pancreatic cancer cell lines and non-neoplastic pancreatic cell line HPDE To identify genes epigenetically silenced and regulated in pancreatic cancer We compared the gene expression profiles of 6 pancreatic cancer cell lines (panc215, A32-1, A38-5, panc2.5, panc2.8, and panc3.014), to the non-neoplastic pancreas cell line, HPDE. We also compared the baseline gene expression of the pancreatic cancer cell lines to expression patterns after treatment with 5-aza-dC alone, TSA alone, and to a combination of 5-aza-dC/TSA.

Proteoglycan expression correlates with the phenotype of malignant and non-malignant EBV-positive B-cell lines.

Project description:The involvement of proteoglycans (PGs) in EBV-host interactions and lymphomagenesis remains poorly investigated. In this study, expression of major proteoglycans (syndecan-1, glypican-1, perlecan, versican, brevican, aggrecan, NG2, serglycin, decorin, biglycan, lumican, CD44), heparan sulphate (HS) metabolic system (EXT1/2, NDST1/2, GLCE, HS2ST1, HS3ST1/2, HS6ST1/2, SULF1/2, HPSE) and extracellular matrix (ECM) components (collagen 1A1, fibronectin, elastin) in primary B cells and EBV carrying cell lines with different phenotypes, patterns of EBV-host cell interaction and viral latency stages (type I-III) was investigated. Primary B cells expressed a wide repertoire of PGs (dominated by serglycin and CD44) and ECM components. Lymphoblastoid EBV+ B cell lines (LCLs) showed specific PG expression with down-regulation of CD44 and ECM components and up-regulation of serglycin and perlecan/HSPG2. For Burkitt's lymphoma cells (BL), serglycin was down-regulated in BL type III cells and perlecan in type I BL cells. The biosynthetic machinery for HS was active in all cell lines, with some tendency to be down-regulated in BL cells. 5'-aza-dC and/or Trichostatin A resulted in transcriptional upregulation of the genes, suggesting that low expression of ECM components, proteoglycan core proteins and HS biosynthetic system is due to epigenetic suppression in type I cells. Taken together, our data show that proteoglycans are expressed in primary B lymphocytes whereas they are not or only partly expressed in EBV-carrying cell lines, depending on their latency type program.
