RNA interference in Manduca sexta induced by double-stranded RNA feeding
Poster Sep 13, 2008
We used a double-stranded RNA feeding approach to silence cadherin-like gene: a protein reported as receptor in several lepidopteran insects for the Cry toxins synthesized by Bacillus thuringiensis. We analized the protein expression from dsRNA-fed and untreated laravae on western blott. M. sexta larvae that ingested dsRNA directed against cadherin exhibited a dramatic suppression of the protein and are resistant to the effect of the Cry1Ab toxin.
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
Concern about the safety of food products has increased dramatically with intentionally and non-intentionally added substances (NIAS) used in packaging being of particular interest. APGC and high resolution MS together with a workflow driven process was used to identify unknown compounds in packaging.READ MORE
