|Intended transcriptional gene silencing with siRNA to the human Vascular Endothelial Growth Factor (VEGF) promoter results in VEGF repression through sequence-specific off-targeting|
Joshua Moses, Amber Goodchild and Laurent Rivory
SiRNA designed to target the human VEGF gene promoter revealed a putative candidate for transcriptional gene silencing. However, mutation or deletion of the target site demonstrated that the observed VEGF knockdown was the result of a sequence-specific off-target effect. Bioinformatic and microarray analyses of genes implicated in VEGF transcriptional control followed by knockdown and Western blotting experiments presented one candidate, GRB2, as an unintended target of the VEGF promoter-specifi
|Point-of-care testing for prostate cancer diagnosis |
Y. Uludag; I.E. Tothill
This presentation describes the potential of using a new fully automated QCM biosensor and a commercial SPR biosensor for the detection of PSA, a biomarker for prostate cancer. Initially a new buffer was formulated to eliminate 98% of the non-specific human serum protein binding to the sensors. Obtained results indicate that both instruments can be used for the fast and easy detection of PSA (0.29-150 ng/ml) in serum.
|A Web Interface for Automatic Microarray Analysis|
Enrico Glaab, Jonathan M. Garibaldi, Natalio Krasnogor
DNA-Microarray technology provides a diagnostic tool for studying cancer and genetic diseases, allowing the experimenter to identify disease related genes and predict the tumour type for new cell samples. However, the statistical analysis of microarray data is a time-consuming and error-prone process. To address this problem we have developed a web interface for automatic DNA-microarray analysis, ArrayMining.net, which guides the user through the analysis process and performs automatic parameter

|Resorufin - a lead for a new protein kinase CK2 inhibitor |
Iben Skjøth Sandholt1, Birgitte Brinkmann Olsen1, Barbara Guerra1, Olaf-Georg Issinger1, Brigitte Boldyreff2
Screening of a natural compound library led to the identification of resorufin, as a highly selective and potent inhibitor for protein kinase CK2. Out of 52 kinases tested only CK2 was inhibited. The IC50 values determined for the CK2 holoenzymes were 1.5 µM and for the free catalytic subunits ca. 4 µM. In different cancer cell lines treatment with resorufin led to cell death and endogenous CK2 was inhibited.

James1, Malini Maysuria1, Jeffrey D. Mitton1, Paola Oliveri4, Jennifer L. Osborn3, Tao Peng2, Amber L. Ratcliffe1, Philippa J. Webster1, Eric H. Davidson4, and Leroy Hood5
We describe a novel platform, the nCounter Analysis System, for sensitive, highly multiplexed, digital gene expression analysis based on NanoString’s novel molecular barcoding technology. Detection of individual mRNA molecules using an assigned sequence of six different fluorescent spots per probe are detected, and then the number of times that code sequence appears in a sample are counted.
