View SamplesPancreatic ductal adenocarcinoma (PDA) is characterized by abundant desmoplasia and poor tissue perfusion. These features are proposed to limit access of therapies to neoplastic cells and blunt treatment efficacy. Indeed, several agents that target the PDA microenvironment promote chemotherapy delivery and improve anti-neoplastic responses in murine models of PDA. Here, we employed the FG-3019 monoclonal antibody directed against the pleiotropic matricellular signaling molecule connective tissue growth factor (CTGF/CCN2). FG-3019 treatment increased PDA cell killing and led to a dramatic tumor response without altering gemcitabine delivery. Microarray expression profiling revealed the down-regulation by FG-3019 of several anti-apoptotic transcripts, including the master regulator Xiap, down-regulation of which has been shown to sensitize PDA to gemcitabine. Decreases in XIAP protein by FG-3019 in the presence and absence of gemcitabine were confirmed by immunoblot, while increases in XIAP protein were seen in PDA cell lines treated with recombinant CTGF. Therefore, alterations in survival cues following targeting of tumor microenvironmental factors may play an important role in treatment responses in animal models and, by extension, PDA patients.

View SamplesAll major types of interferon (IFN) efficiently inhibit hepatitis C virus (HCV) replication in vitro and in vivo. Remarkably, HCV replication is not sensitive to IFN in the hepatoma cell line Huh6, despite an intact signaling pathway. We performed transcriptome analyses between Huh6 and Huh-7 to identify effector genes of the IFN response and thereby identified the DExD/H box helicase DDX60L as a restriction factor of HCV replication. DDX60L and its homolog DDX60 were both induced upon viral infection and IFN treatment in primary human hepatocytes. However, exclusively DDX60L knockdown increased HCV replication in Huh-7 cells, and rescued HCV replication from type II IFN as well as type I and III IFN treatment, suggesting that DDX60L is an important effector protein of the innate immune response against HCV. DDX60L had no impact on replication of hepatitis A virus (HAV), but severely impaired production of lentiviral vectors, arguing for a potential antiretroviral activity. Detection of endogenous DDX60L protein turned out to be difficult due to instability. DDX60L knockdown did not alter interferon stimulated gene (ISG) induction after IFN treatment, suggesting that it is a direct effector of the innate immune response. It most likely inhibits viral RNA replication, since we found no impact of DDX60L on translation or stability of HCV subgenomic replicons, nor additional impact on entry and assembly of infectious virus. Similar to its homolog DDX60, DDX60L had a moderate impact on retinoic acid-inducible gene I (RIG-I)-dependent activation of innate immunity arguing for additional functions in the sensing of viral RNA.

View SamplesWe applied Next-Generation Sequencing (NGS) to miRNAs from blood samples of 48 AD (Alzheimer''s Disease) patients and 22 unaffected controls, yielding a total of 140 unique mature miRNAs with significantly changed expression level. Of these, 82 were higher and 58 lower abundant in samples from AD patients. We selected a panel of 12 miRNAs for a qRT-PCR analysis on a larger cohort of 202 samples including not only AD patients and healthy controls but also patients with other CNS illnesses: Multiple Sclerosis, Parkinson''s Disease, Major Depression, Bipolar Disorder, Schizophrenia, and Mild Cognitive Impairment, which is assumed to represent a transitional period before the development of AD. MiRNA target enrichment analysis of the selected 12 miRNAs indicated an involvement of miRNAs in nervous system development, neuron projection, neuron projection development, and neuron projection morphogenesis, respectively. Using this 12-miRNA signature we were able to differentiate between AD and controls with an accuracy of 93.3%, a specificity of 95.1%, and a sensitivity of 91.5%. The differentiation of AD from other neurological diseases was possible with accuracies between 73.8% and 77.8%. The differentiation of the other CNS disorders from controls yielded even higher accuracies. Overall design: Examination of the miRNA profile in blood samples of 48 AD patients and 22 controls

View SamplesThe transcription factor Nkx2.5 is required for specification of pharyngeal arch second heart field (SHF) progenitors that contribute to outflow tract (OFT) and right ventricle (RV) formation. Multiple sets of microarray data were analyzed to identify genes that are candidate targets of Nkx2.5 in the second heart field. These sets are: 1) publicly available data for cardiothoracic tissue from E9.5 Nkx2.5 wild-type, heterozygous and homozygous embryos; 2) an analysis of mouse E10.5 pharyngeal arch tissue; 3) an analysis of mouse E12.5 heart tissue; and 4) a temporal analysis of the cardiogenic cell line P19CL6. This combined analysis identified 11 genes (Lrrn1, Elovl2, Safb, Slc39a6, Khdrbs1, Hoxb4, Fez1, Ccdc117, Jarid2, Nrcam, and Enpp3) expressed in SHF-containing pharyngeal arch tissue whose regulation is dependent on Nkx2.5 expression.
Jarid2 is among a set of genes differentially regulated by Nkx2.5 during outflow tract morphogenesis.

View SamplesPluripotent P19CL6 embryonic carcinoma cells can be differentiated to a cardiac lineage by culture in the presence of DMSO. The goal of this study was to characterize temporal gene expression patterns associated with cardiogenic differentiation. Gene expression analysis was conducted on differentiating P19CL6 cells at several time points following induction with 1% DMSO. Samples were processed for analysis by Affymetrix GeneChip.
