Here we show specific cytotoxicity resulting from siRNA-induced silencing of EEF2, as well as specific delivery to PSMA-expressing prostate cancer cells. Increasing the valency of the aptamer resulted in enhanced cytotoxicity compared with the monovalent constructs. The results presented here demonstrate the usefulness of multivalent aptamer-based delivery vehicles for siRNA therapeutics.

Unannotated transcripts, including antisense, noncoding, intergenic, and potential regulatory RNAs, were identified in three different eukaryotic model organisms by cDNA cloning and sequencing. A rapid double-stranded cDNA generation system will be described.

The lack of reference materials (RMs) for most genetic tests causes difficulties in validating and developing new assays, and results in tests being run without proper quality controls. EuroGentest and the EU-funded network for Medical Genetics, is addressing this issue by defining the present and future needs for RMs, setting priorities for and supporting the development of new RMs and building an enduring network involving all stakeholders in RM development.

We enhanced the gene prediction program GeneID with a framework for detecting U12-dependent introns without appreciable loss in gene prediction sensitivity or specificity. We present statistics on the performance of the U12-enhanced GeneID on a test set of known U12-intron-possessing genes as well as results for scans of both the ENCODE regions and the entire human genome.

In this study we compare methods for large-scale microarray analysis of protein and RNA level changes in HL-60 cells, responding to differentiation stimuli. Using microarrays we have found, that level of several proteins was either up- or down-regulated after cell differentiation. In some cases there was significant correlation with appropriate genes.

Gene expression pattern of 14 members of RLCK class VI in Arabidopsis is described. qRT-PCR was used to determine the transcript levels in the various organs of plant as well as under a series of abiotic stress/hormone treatments in seedlings.

The cDNA libraries from single oocytes and pre-implantation buffalo embryos from 2 cell stage to blastocyst were established. Relative expression studied with RT-PCR of IGF-I showed an increase at 12h and decline at 24h of IVM oocytes. IGF-IR was expressed at cleavage stages to blastocyts. Glut-I was expressed in IVM oocytes and SCNT embryos at all stages. Gene expression of IGF-I, IGF-IR and Glut-I plays an important role in SCNT embryo production.

We have developed a web-based database, "PRIMe (Platform for RIKEN Metabolomics)," which contains powerful tools for researchers to analyze gene co-expression data and mass spectral data. PRIMe has been developed with the main aim of facilitating integrated analysis for transcriptomics and metabolomics.

New technologies are needed to deal with live cell-based HCS assays on non-adherent cells or to exploit suspension cells in fluidic systems. Here we describe CyGEL™ - a thermo-reversible hydrogelbased 4-D immobilization technology for live cell location without imposing an anchoring to a substrate.

We demonstrate that DNA methylation patterns can serve as characteristic markers to distinguish different cell types. We have identified panels of methylation markers that are specific to mesenchymal stem cells or various differentiated cell types in the mesenchymal lineage. This method of cell type identification has a number of advantages over conventional markers in that it is robust, is both qualitative and quantitative.
