NextSeq 500
Description
Molecular heterogeneity among spiral ganglion neurons (SGNs) in the mouse cochlea was investigated in two genetic backgrounds: 1) wildtype, 2) Vglut3-/-, which lack inner hair cell-driven glutamatergic activation of SGNs. Overall design: Individual spiral-ganglion neurons expressing the fluorescent reporter tdTomato were dissociated and manually placed into PCR tubes; single-cell libraries were made by the Smart-seq2 approach; sequencing was done using the NextSeq platform (Illumina) at an average read depth of 4.5 million; bioinformatic analysis was conducted in R. Genotypes: bhlhb5::cre/+; Ai14/+ (wildtype) and bhlhb5::cre/+;Ai14/+; Vglut3-/- (Vglut3-/-). Age: P25-P27

- Drosophila Gene 1.0 ST Array (drogene10st)
Description
PFJ (4 ml for a final concentration of 19,000 mg gallic acid equivalent (GAE) per kg diet or 0.86 mg GAE per kcal diet) was supplemented to larvae of fruit flies (Drosophila melanogaster) given a semi-purified diet to observe for possible effects on energy metabolism and lifespan. Larvae were used five days since the egg stage for gene expression studies. Results from the microarray data analysis carried out show that fruit fly larvae given PFJ had up-regulated transport and metabolic processes, while development and morphogenesis processes were down-regulated.

Fat bodies extracted from these larvae were used five days since the egg stage for gene expression studies. Results from the microarray data analysis carried out show that fruit fly larva fat bodies given PFJ had up-regulated heat shock protein genes, while cell cycle and growth genes were down-regulated.

Description
Background :To evaluate the impact of the duration of chronic inflammation on gene expression in skeletal muscle biopsies (MBx) from untreated children with juvenile dermatomyositis (JDM) and identify genes and biological processes associated with the disease progression, expression profiling data from 16 girls with active symptoms of JDM greater or equal to 2 months were compared with 3 girls with active symptoms less than 2 months.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The Hippo pathway is an emerging signaling cascade involved in the regulation of organ size control. It consists of evolutionally conserved protein kinases that are sequentially phosphorylated and activated. The active Hippo pathway subsequently phosphorylates a transcription coactivator, YAP, which precludes its nuclear localization and transcriptional activation. Identification of transcriptional targets of YAP in diverse cellular contexts is therefore critical to the understanding of the molecular mechanisms in which the Hippo pathway restricts tissue growth.
Publication Title
Hippo signaling regulates microprocessor and links cell-density-dependent miRNA biogenesis to cancer.

Description
Cell fate specification of neural stem/progenitor cells (NSCs) is an intricate developmental process that determines neural cell identity. While transcriptional mechanisms undoubtedly affect this process, translational mechanisms are much less understood. Here we show that deficiency of the chromatin remodeler Chromodomain Helicase DNA binding protein 5 (Chd5) causes transcriptional de-repression of multiple ribosomal subunit genes, increases protein synthesis, and expands the activated stem cell pool leading to perturbation of NSC fate. Compromised H3K27me3 in Chd5 deficient NSCs during early cell fate specification underlies the generation of excessive astrocytes at the expense of neurons at later stages of differentiation. Chd5 expression rescues these cell fate defects while simultaneously reestablishing H3K27me3, and inhibition of the H3K27me3-specific demethylase Utx restores appropriate cell fate specification in NSCs lacking Chd5. These findings define a Chd5-Utx-H3K27me3 axis pivotal in ribosome biogenesis and translation during neurogenesis, consistent with compromised CHD5 being implicated in glioma. Overall design: mRNA profiles of primary neural/stem progenitor cells (NSCs) of wild type (+/+) and Chd5-/- mice were generated, in duplicate, using Illumina NextSeq 500.
