Martina Doleshal 1, Anna E. Szafranska 1, Hayward S. Edmunds 2, Gregory J. Tsongalis 2, Murray Korc 2 and Emmanuel Labourier 1
Collection of pancreatic fine needle aspirates (FNAs) in RNARetain™ allows stabilization and protection of RNA in tissues containing high levels of nucleases; Differential miRNA expression in pancreatic FNAs accurately classifies benign and malignant tissue; Combinations of miRNA and mRNA expression signatures improve the separation between normal tissue and chronic pancreatitis; microRNAs are suitable analytes for molecular characterization of fine needle aspirates from pancreatic tissues.
|A high-throughput protein array-based approach |
Rachel Van Dyk, Claudia Kirisits, Paul Potter, Fook Tim Chew, Reinhard Hiller
Here we present a novel discovery-oriented high-throughput approach to the screening of allergen reactivates in crude biological extracts is presented using seafood allergens as an example. The CPGR workflow permits the effective screening of hundreds of putative allergens in parallel using minute amounts of patient serum and constitutes a cost-efficient allergen-specific antibody screening method for a routine diagnostic setting.
|Accuwik® Ultra Membrane for the Direct Collection, Storage, and Efficient Rapid Release of Biological Samples for Clinical Diagnostics|
Galina Fomovska, Stephane Perreault, Richmond Lo, and Martin A. Smith
Poster data assesses use of Pall’s Accuwik Ultra membrane as a reliable tool for direct collection of clinical samples including saliva and plasma, enables stability during sample storage, and allows for rapid and efficient release of clinically relevant protein biomarkers suitable for diagnostic analyses.
|Expression of stress response protein GRP78 is associated with the development of castration-resistant prostate cancer|
Llana Pootrakul, Anirban P. Mitra, Ram H. Datar, Shan-Rong Shi, Jie Cai, Debra Hawes, Susan G. Groshen, Amy S. Lee, Richard J. Cote
This study investigated the role of the GRP78 in prostate cancer progression and the development of castration-resistant prostate cancer, where cancer cells continue to survive despite the stress of an androgen-starved environment.
|Application of genetic programming in analysis of quantitative gene expression profiles for identification of nodal status in bladder cancer|
Anirban P. Mitra, Arpit A. Almal, Ben George, David W. Fry, Peter F. Lenehan, Vincenzo Pagliarulo, Richard J. Cote, Ram H. Datar, William P. Worzel
Nodal involvement in bladder cancer is an independent indicator of prognosis. This study employed an iterative machine learning process called genetic programming on quantitative expression values of 70 genes to classify primary urothelial carcinoma samples into those associated with or without nodal metastasis. The generated rules showed a strong predilection for ICAM1, MAP2K6 and KDR resulting in gene expression motifs that cumulatively suggested a pattern ICAM1>MAP2K6>KDR for node positive ca
|Interactive Transcription Maps Over Microarray Data|
Petr Krontorad, Irena Koutna and Michal Strehovsky
For final description of microarray experiment results it is necessary to use some statistically robust method. Transcription maps (TM) are used to map results of gene expression analysis into individual chromosomes. We have implemented graphical tool for interactive display of TMs. This tool allows displaying of arbitrary information for each gene.
|Whole Body Endogenous Nitric Oxide Production in Patients with Decompensated Liver Disease|
Demoncheaux E., Elphick D.A., Dürner M.B., Higgins G.E., Crowther D., Williams E.J., Higenbottam T.W and Gleeson D
Increased nitric oxide (NO) production has been implicated in the pathogenesis of the hyperdynamic circulation found in patients with advanced liver disease. There were no differences between patients with liver disease and controls with regard whole body NO production. Our results, in a well characterised set of patients, argue against greater basal NOS-dependent whole body NO production in patients with decompensated liver disease.
|Caveolin-1 Expression as a Possible Biomarker in Pancreatic Cancer Diagnosis|
C. Tanase, E. Raducan, L. Albulescu, E. Codorean, M.I. Nicolescu, D.I. Popescu, M.L. Cruceru and A.C. Popa
Caveolin1 (Cav-1) function either as a tumor supressor or as a promoter of metastasis. Overexpresion of cav-1 was correlated with: tumoral grading, proliferration markers (Ki67, p53), serum tumor markers (CEA, CA19.9) and angiogenic markers (VEGF, bFGF).
|A Novel Miniaturized Cell Lysis Device Using Spherically Focused Ultrasound|
Gang Li, Hong Xiao, Min Guo and Jing Cheng
A prototype of miniaturized cell lysis device has been developed using a spherically concave transducer, which is capable of lysing bacteria in absence of added chemical denaturants or enzymes and lysing yeast efficiently without any mechanical or enzymatic pretreatment.
