siRNA Design Including Secondary Structure Target Site Prediction
Poster Nov 24, 2005
AbstractWhen performing RNAi experiments using siRNAduplexes, the first critical challenge is the design ofefficient siRNA. Recent studies concerning the importanceof mRNA accessibility in relation to the efficiency of siRNAsilencing has led MWG Biotech to create an online designtool allowing researchers to view the mRNA target site.
Preliminary data underlines the correlation between the siRNA knockdown efficiency and the local free energy of the mRNA target site. There is a strong evidence that considering the mRNA secondary structure within the siRNA design algorithm will lead to more efficient siRNAs.
Despite the developments in conventional PCR, the complexity of multiplex Real Time PCR is still limited due to the lack of sufficient detection channels. To achieve high-end multiplexing capacity on standard Real Time PCR machines, Anapa Biotech has developed the MeltPlex® technology (see box on right).READ MORE
Genome-wide association studies (GWAS) have identified more than 100 genetic loci associated with type 2 diabetes. The majority of these are located in the intergenic or intragenic regions suggesting that the implicated variants may alter chromatin conformation. This, in turn, is likely to influence the expression of nearby or more remotely located genes to alter beta cell function. At present, however, detailed molecular and functional analyses are still lacking for most of these variants. We recently analysed one of these loci and mapped five causal variants in an islet-specific enhancer cluster within the STARD10 gene locus. Here, we aimed to understand how these causal variants influence b-cell function by alteration of the chromatin structure of enhancer clusterREAD MORE
The nuclear receptors pregnane X receptor (PXR) and constitutive androstane receptor (CAR) are closely related transcription factors that regulate the expression of phase I (cytochrome P450s), phase II metabolizing enzymes and transporter genes in response to xenobiotics, including prescription drugs.READ MORE
