Description
Circuit neuroscience has made great progress by linking neuronal function to marker gene expression, allowing the specific investigation of otherwise indistinguishable neuronal ensembles. Here, we performed next generation sequencing on two functionally and genetically distinct interneuronal populations marked by the expression of protein kinase C d (PKCd) or somatostatin (SST) in the central amygdala (CEA) of mice, which are known to play distinct and sometimes opposing roles in emotion processing. Making their gene expression profile known will aid in forming hypotheses of how different neurotransmitters or psychoactive drugs could alter information processing in these neurons. Overall design: Unchallenged gene expression profile of two different neuronal populations in the central amygdala

Description
Background: NK cells during chronic viral infection have been well studied over the last decade. We performed an unbiased next-generation RNA-sequencing approach to identify commonalities or differences of the effect of HIV, HCV and HBV viremia on NK cell transcriptomes. Methods: Using cell sorting, we obtained CD3-CD56+ NK cells from blood of 6 HIV, 11 HCV, and 32 HBV infected and untreated patients. Library preparation and sequencing were done using Illumina mRNA-Seq Sample Prep Kit and the HiSeq 2000, HiSeq2500 or NextSeq 500, and further analysis by an in-house analytic pipeline. Results: In NK cells from HIV, HCV and HBV patients, transcriptome analysis identified 272, 53, and 56 differentially expressed genes, respectively (fold change >1.5, q-value 0.2). Interferon stimulated genes were induced in NK cells from HIV/HCV patients, but not during HBV infection. HIV viremia downregulated ribosome assembly genes in NK cells. In HBV, viral load and ALT variation had little effect on genes related to NK effector function. Conclusion: We compare, for the first time, NK cell transcripts of viremic HIV, HCV and HBV patients. We clearly demonstrate distinctive NK cell gene signatures in 3 different populations, suggestive for a different degree of functional alterations of the NK cell compartment as compared to healthy individuals. Overall design: We analyzed NK cell transcripts collected from the blood of well-characterized chronic HBV patients (n=32), chronic HCV patients (n=8), and HIV patients (n=6). Differential gene expression analysis, global module analysis, and unsupervised clustering analysis were performed by employing RNA-sequencing on blood NK cell transcriptomes.

Description
Primary pre-B acute lymphoblastic (ALL) cells do not proliferate long-term ex vivo without the presence of stromal support. We developed and use an ex vivo co-culture model, consisting of mouse leukemic pre-B Bcr/Abl-expressing ALL cells grown with mitotically inactivated mouse embryonic fibroblasts (MEFs). This system provides a generic type of environmentally-mediated protection to the ALL cells, because when the ALL cells are treated with a moderate dose of a therapeutic drug, drug-resistant ALL cells can be recovered after a 1-2 week period of culture. Some of the factors produced by stromal cells that provide protection to ALL cells have been identified. However, it is unclear if the presence of drug-treated ALL cells affects the stromal fibroblasts. The current study was initiated to examine this using expression profiling on the irradiated MEFs.

Description
EML1 and EML3 were previously shown to be histone readers involved in plant-pathogen interactions. To learn more about the developmental function of EML1 and EML3, we generated eml1 eml3 double mutant and showed that it had specific seed developmental phenotypes, including a capability to develop seed without fertilization. Next, we analyzed the mRNA expression of genes in the eml1 eml3 double mutant and compared it to its wild type. Differentially expressed (DE) genes in the mutant were identified and compared with DE of the mutants known to be involved in regulating seed development and in fertilization-independent endosperm development. Our results suggest that some targets are shared between EML histone readers and known regulators of seed development, such as MEA. Auxin response seems to be affected in both types of mutants. However, unlike MEA, EML proteins regulate auxin responsive genes not only in the endosperm, but also in the embryo. This capability makes EML proteins very good candidates for engineering apomictic seeds. Overall design: 3 eml1,eml3 double mutant samples and 3 WT samples
