Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Phloem-feeding pests cause extensive crop damage throughout the world yet little is understood about how plants perceive and defend themselves from these threats. The silverleaf whitefly (SLWF; Bemisia tabaci type B) is a good model for studying phloem-feeding insect-plant interactions as SLWF nymphs cause little wounding and have a long, continuous interaction with the plant. Using the Arabidopsis ATH1 GeneChip, the global responses to Silverleaf Whitefly 2nd instar feeding were examined.

Description
ES cell-derived neurons of forebrain identity were isolated by magnetic sorting, cultured for 7 days and transduced with either Nurr1 or eGFP lentivirus. After an additional 12 h in culture, mRNA was isolated and subjected to microarray analysis.

Illumina HiSeq 2000
Description
We recently identified pathogenic KIF1Bb mutations in sympathetic nervous system malignancies that are defective in developmental apoptosis. Here we deleted KIF1Bb in the mouse sympathetic nervous system based on a cre recombination system driven by the dopamine beta hydroxylase (DBH) promoter. We observed impaired sympathetic nervous function and misexpression of genes required for sympathoadrenal lineage differentiation in KIF1Bb deficient sympathetic ganglia. Overall design: We analyzed superior cervical ganglia from post-natal day 1 mice. We compared ganglia from four wild-type control animals (KIF1Bb fl/fl) with ganglia from four animals with conditional knockout of KIF1Bb (KIF1Bb fl/fl : DBHcre +/-).

Description
During development neuronal progenitors compete for growth factors such as nerve growth factor NGF and require the prolyl hydroxylase EglN3 and the kinesin KIF1Bß for developmental apoptosis. Inherited KIF1Bß loss-of-function mutations in neuroblastomas and pheochromocytomas implicate KIF1Bß as a 1p36.2 tumor suppressor, however the mechanism of tumor suppression is unknown. We found that KIF1Bß interacts with the RNA helicase A (DHX9) resulting in DHX9 nuclear accumulation to regulate apoptosis. KIF1Bß-dependent DHX9 nuclear localization leads to transcription of the apoptotic target XIAP-associated factor 1. DHX9 is induced when NGF is limiting and required for apoptosis in cells deprived of NGF. Overall design: NB1 cells were transduced to incorporate shRNA against DHX9 or a scrambled control, and transfected with a KIF1Bß expression vector or control, then transfected cells were isolated and lysed after 48h.

Description
The objectives of this study were to understand the effect of phenolic compounds from fermented berry beverages on hyperglycemia and obesity in vivo using mice fed a high fat diet. Our hypothesis was that consumption of a fermented blueberry-blackberry beverage and its phenolic compounds would reduce the development of obesity and hyperglycemia in diet-induced obese mice. Body composition, histomorphological analysis of pancreatic islets and liver, and expression of genes involved in obesity and hyperglycemia were evaluated in order to explain the modulation of diet-induced obesity and hyperglycemia due to treatments.

Description
In this study, we developed an extensive dataset for a GBM case via the generation of polyclonal and monoclonal glioma stem cell lines from initial diagnosis, as well as from multiple sections of distant tumor locations of the deceased patients brain following tumor recurrence. Our analyses revealed the tissue-wide expansion of a new clone in the recurrent tumor as well as chromosome 7 gain and chromosome 10 loss as repeated genomic events in primary and recurrent disease. Moreover, chromosome 7 gain and chromosome 10 loss produced similar alterations in mRNA expression profiles in primary and recurrent tumors despite possessing other highly heterogeneous and divergent genomic alterations between the tumors. We identified ETV1 and CDK6 as putative candidate genes, and NFKB (complex), IL1B, IL6, Akt and VEGF as potential signaling regulators, as potentially central downstream effectors of chr7 gain and chr10 loss. Finally, the differences caused by the transcriptomic shift following gain of chromosome 7 and loss of chromosome 10 were consistent with those generally seen in GBM samples compared to normal brain in large-scale patient-tumor data sets.

Description
Gliomas are mostly incurable secondary to their diffuse infiltrative nature. Thus, specific therapeutic targeting of invasive glioma cells is an attractive concept. As cells exit the tumor mass and infiltrate brain parenchyma, they closely interact with a changing micro-environmental landscape that sustains tumor cell invasion.

Identification of molecular pathways facilitating glioma cell invasion in situ.
