Description
T4 and T5 neurons are components of the neuronal circuit for motion vision in flies. To identify genes involved in neuronal computation of T4 and T5 neurons, we perfomed transcriptome analysis. Nuclei of T4 and T5 neurons were immunoprecipitated, total RNA was harvested and used for mRNA-seq with Illumina technology. In two biological replicates, we mapped 154 and 119 million reads to D. melanogaster genome. mRNA-seq provided information about expression levels of 17,468 annotated transcripts in the T4 and T5 neurons. Overall design: Cell type – specific transcriptome analysis of the RNA isolated from immunoprecipitated nuclei, performed in two biological replicates

Description
Elevated levels of androgen receptor (AR) in prostate cancer confer resistance to current antiandrogens and play a causal role in disease progression due to persistent target gene activation. Through pharmacologic and genetic approaches, we show that half of all direct AR target genes, including TMPRSS2, the primary driver of ETS fusion transcripts in 70 percent of human prostate cancers, require histone deacetylase (HDAC) activity for transcriptional activation by AR. Surprisingly, the HDAC3-NCoR complex, which typically functions to repress gene expression by nuclear receptors, is required for AR target gene activation. Prostate cancer cells treated with HDAC inhibitors have reduced AR protein levels, but we show that the mechanism of blockade of AR activity is through failure to assemble a coactivator/RNA polymerase II complex after AR binds to the enhancers of target genes. Failed complex assembly is associated with a phase shift in the cyclical wave of AR recruitment that typically occurs in response to ligand treatment. HDAC inhibitors retain the ability to block AR activity in hormone refractory prostate cancer models and therefore merit clinical investigation in this setting. HDAC-regulated AR target genes defined here can serve as biomarkers to ensure sufficient levels of HDAC inhibition.

Description
The ubiquitous efflux transporter ATP-binding cassette sub-family C member 5 (ABCC5) is present at high levels in the blood-brain barrier, neurons and glia, but its in vivo substrates and function are not known. Untargeted metabolomic screens revealed that Abcc5-/- mice accumulate endogenous glutamate conjugates and analogs in several tissues, but brain in particular. The abundant neurotransmitter N-acetylaspartylglutamate (NAAG), for example, was over 2-fold higher in Abcc5-/- brain. In line with ABCC5-mediated transport, the metabolites that accumulated in Abcc5-/- tissues were depleted in cultured cells that overexpressed human ABCC5. Using membrane vesicles, we show that ABCC5 not only transports the metabolites detected in our screen, but also a wide range of peptides containing a C-terminal glutamate. Glutamate conjugates are of physiological relevance because they can affect the function of glutamate, the principal excitatory neurotransmitter in the brain. We found that ABCC5 also transports exogenous glutamate analogs, like the classic excitotoxic neurotoxins kainic acid, domoic acid and N-methyl-D-aspartate (NMDA) and the therapeutic glutamate analog ZJ43. Taken together, we have identified ABCC5 as a general glutamate conjugate and analog transporter that affects the disposition of endogenous metabolites, toxins and drugs. Overall design: A set of 5 wildtype brains was compared to a set of 5 Abcc5-knockout mouse brains
