Improved FFPE RNA isolation, novel TR priming for complete recovery of FFPE mRNA fragments. Differential expression defines Scores for tumor classification: comparing fresh-frozen with FFPE. Novel flow-through Ziplex microarray platform demonstrates MAQC performance level of data obtained with FFPE samples.

FOXP3 Gene Expression in Multiple Sclerosis patients before and after Mesenchymal Stem Cell therapy

Multiple Sclerosis (MS) is a chronic inflammatory demyelinating disorder of the CNS. No successful treatment for MS, but one therapeutic strategy in research is the use of bone marrow-derived mesenchymal stem cells (MSC). We studied a group of MS patients who underwented MSCs, assayed for expression of a transcription factor, FOXP3, as a specific marker of MS amelioration in peripheral blood. qRT-PCR on PBMCs showed higher FoxP3 levels.

miRNA deregulation is an important hallmark on cancer development and progression. This work shows that miR-21 is overexpressed is human glioblastoma samples and cell lines, whereas miR-128a is highly downregulated on these tumours. miRNA modulation using antisense oligonucleotides and/or miRNA precursor molecules decreased tumor cell viability. Thus, targeting deregulated miRNAs may constitute a complementary/alternative approach on the treatment of glioblastomas and other miRNA-related maligna

Partial characterization of nitrate signaling pathway of Arthrospira platensis PCC 7345
Pradeep kumar L, and Vani B., Centre for Biotechnology, Biological Science Group, Birla Institute of Technology and Science, Pilani- 333031 , Rajasthan, India. ,
The present study is to elucidate the signaling network involved in nitrate uptake and assimilation of Arthrospira platensis. Expression of adenylate cyclase, cyaC was found to be nitrate signal dependent. The involvement cAMP was also observed in different levels of nitrate signaled assimilatory pathway. We have used differential display to identify a histidine kinases in the nitrate signaling of Arthrospira platensis.

Chemically Modified Primers for Improved Multiplexed PCR

Multiplex PCR is an advantageous technique used in PCR applications to amplify multiple targets in a single reaction. As useful as it is, this technique presents a new set of challenges that further complicates PCR setup. For example, reactions are more prone to off-target amplifications such as mis-priming and primer dimer due to the increased number of primer pairs. Furthermore, preferential amplification of certain targets leads to an unequal distribution of amplicon products, making quantifi

Hot Start dNTPs - A Novel Tool for Controlled Nucleotide Incorporation in PCR
Tony Le, Elena Hidalgo Ashrafi, Sabrina Shore, Victor Timoshchuk, Natasha Paul, Richard Hogrefe, Inna Koukhareva, Alexandre Lebedev, TriLink BioTechnologies,
PCR is a widely used scientific tool employed by a variety of applications. Various Hot Start technologies have already been developed using modified PCR components to increase specificity of a reaction. Recently developed CleanAmpTM dNTPs are modified nucleoside triphosphates with a thermolabile 3’-tetrahydrofuranyl protecting group that is released at higher temperatures. These modified dNTPs prevent low temperature primer extension, which can often be a significant problem in PCR. At higher t
