- Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
The SIVmac251 macaque model has been used to evaluate the efficacy of vaccine for HIV. Exposure of macaques to a single high dose of SIVmac251 results in transmission of multiple viral variants, which contrasts the few HIV variants typically transmitted in humans. In here, we investigated whether the dose of SIVmac251 challenge affected vaccination efficacy and found that exposure of the immunized macaques to single high dose of SIVmac251 resulted in no vaccine efficacy, whereas exposure to a tenfold lower dose resulted in protection from SIVmac251 acquisition and protection from disease in animals that become infected. The dose of challenge did not affect the expression of inflammatory genes in the gut in acute infection, but at set point, a significant down regulation of interferon responsive genes and up regulation of genes involved in B and T-cell responses, was observed only in vaccinated animals exposed to a lower dose of SIVmac251. Accordingly, in these animals, we also found a significant correlation with vaccine induced T-cell responses and protection from disease. These data demonstrate that the evaluation of the efficacy of vaccine candidates for HIV relies on accurate modeling in macaques to better mimic HIV transmission to humans.

Illumina HiSeq 2500
Description
This dataset contains collected RNASeq data of 552 samples from the GOYA clinical trial. Overall design: The GOYA trial tested the efficacy of Gazyva (GA101) compared with Rituxan (Rituximab) in first line, untreated DLBCL patients. Patients were randomized 1:1 to either G or R combined with a CHOP chemotherapy backbone. Tumor samples were collected at baseline, RNA was isolated using RNA-Access, and RNASeq was run with TruSeq (Illumina) RNASeq.
Publication Title

Description
Ets-4 was previously identified as a suppressor of rege-1(rrr13) phenotype. The goal of this experiment was to identify down-stream regulators of ETS-4, which facilitate this suppression. Overall design: mRNA profiling of C.elegans young adults of ets-4 knockdown or mock RNAi control in the background of rege-1(rrr13)

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Natural killer (NK) cells can be divided into phenotypic subsets based on the expression of receptors that bind self-MHC-I molecules with differing affinities; a concept termed licensing or education. Here we show that NK cell subsets exhibit markedly different migratory, effector, and immunoregulatory functions on dendritic cells and antigen-specific CD8+ T cell responses during influenza and murine cytomegalovirus infections. Shortly after infection, unlicensed NK cells preferentially trafficked to draining lymph nodes and produced GM-CSF, which promoted the expansion and activation of dendritic cells, and ultimately resulted in sustained antigen-specific CD8+ T cell responses. In contrast, licensed NK cells preferentially migrated to infected parenchymal tissues and produced greater levels of interferon- (IFN-). Importantly, human NK cell subsets exhibited similar phenotypic characteristics and patterns of cytokine production. Collectively, our studies demonstrate a critical demarcation between the functions of licensed and unlicensed NK cell subsets, with the former functioning as the classical effector subset in inflamed tissues and the latter as modulators of adaptive immunity helping to prime immune responses in draining lymph nodes.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The v-erbA oncogene belongs to a superfamily of transcription factors called nuclear receptors, which includes the retinoic acid receptors (RARs) responsible for mediating the effects of retinoic acid (RA). Nuclear receptors bind to specific DNA sequences in the promoter region of target genes and v-erbA is known to exert a dominant negative effect on the activity of the RARs. The repressor activity of v-erbA has been linked to the development of hepatocellular carcinoma (HCC) in a mouse model. We have used microarray analysis to identify genes differentially expressed in hepatocytes in culture (AML12 cells) stably transfected with v-erbA and exposed to RA. We have found that v-erbA can affect expression of RA-responsive genes. We have also identified a number of v-erbA-responsive genes that are known to be involved in carcinogenesis and which may play a role in the development of HCC.
Publication Title
Modulation of expression of RA-regulated genes by the oncoprotein v-erbA.
