Description
Mouse glioblastomas were induced by lentiviral vector expressing HrasG12V and shRNA against p53. Tumor tissues were isolated from mice reached clinical endpoints. RNA was isolated using the RNeasy kit according to manufacturer’s protocol with the addition of DNase (Qiagen). cDNA libraries were prepared using the TruSeq RNA Sample Prep kit (Illumina). RNA sequencing was performed using a HiSeq 2500 Sequencing System (Illumina). Overall design: 3 normal mouse brain samples compared to 5 glioblastoma samples by standard RNAseq method.

Description
Transgenic GFAP-, NES-, and SYN- CRE mice were injected with a lenti-viral construct containing a floxed RFP directly upstream of a cassette containing si-p53, GFP, and mutant HRAS. Tumors arising from the various CRE tissue specific promoters and differing injections sites were compared to normal hippocampus and cortex.

Description
Tumor microenvironment plays a pivotal role in cancer progression; however, little is known regarding how differences in the microenvironment affect characteristics of cancer cells. Here, we investigated the effects of tumor microenvironment on cancer cells by using mouse tumor models. After 3 cycles of inoculation and extraction of human pancreatic cancer cells, including SUIT-2 and Panc-1 cells, from tumors, distinct cancer cell lines were established; 3P cells from the pancreas obtained using the orthotopic tumor model, and 3sc cells from subcutaneous tissue obtained using the subcutaneous tumor model. On cell re-inoculation of these cells, the 3sc cells and, more prominently, the 3P cells, exhibited higher tumorigenic activity than the parental cells. The 3P cells specifically exhibited low E-cadherin expression and high invasiveness, suggesting that they were endowed with the highest malignant characteristics. RNA-sequence analysis demonstrated that distinct signaling pathways were activated in each cell line and that the 3P cells acquired a cancer stem cell-like phenotype. Among cancer stem cell-related genes, those specifically expressed in the 3P cells, including NES, may be potential new targets for cancer therapy. The mechanisms underlying the development of highly malignant cancer cell lines were investigated. Individual clones within the parental cells varied in tumor-forming ability, indicating the presence of cellular heterogeneity. Moreover, the gene expression profile of each clone changed after orthotopic inoculation. The present study thus suggests that both selection and education processes are involved in the development of highly malignant cancer cells. Overall design: Expression of mRNA in the highly malignant sublines of SUIT-2 and Panc-1 cells xenografted into mice.

Description
Human cytomegalovirus (HCMV) is an important pathogen with multiple immune evasion strategies, including virally facilitated degradation of host antiviral restriction factors. Here, we describe a multiplexed approach to discover proteins with innate immune function on the basis of active degradation by the proteasome or lysosome during early phase HCMV infection. Using three orthogonal proteomic/transcriptomic screens to quantify protein degradation, with high confidence we identified 35 proteins enriched in antiviral restriction factors. A final screen employed a comprehensive panel of viral mutants to predict viral genes that target >250 human proteins. This approach revealed Helicase-like Transcription Factor (HLTF), a DNA helicase important in DNA repair, potently inhibits early viral gene expression but is rapidly degraded during infection. The functionally unknown HCMV protein UL145 facilitates HLTF degradation by recruiting the Cullin4 E3 ligase complex. Our approach and data will enable further identifications of innate pathways targeted by HCMV and other viruses. Overall design: 9 samples comprising three sets of three replicates (0h, 24h, 72h)

Description
Plasmodium berghei ANKA infection in mice is used as a model for human cerebral malaria, the most severe complication of Plasmodium falciparum infection. The response of brain cells such as microglia has been little investigated, and may play a role in the pathogenesis or regulation of cerebral malaria. We showed previously that microglia are activated in P. berghei infections, and that Type 1 Interferon signaling is important for activation. This dataset contains the transcriptome of brain microglia of infected mice in the presence and absence of Type I interferon signaling, with the aim of identifying the genes involved in this pathway in microglia during experimental cerebral malaria.

Description
The tissue-specific pattern of mRNA expression can indicate important clues about gene function. High-density oligonucleotide arrays offer the opportunity to examine patterns of gene expression on a genome scale. Toward this end, we have designed custom arrays that interrogate the expression of the vast majority of protein-encoding human and mouse genes and have used them to profile a panel of 79 human and 61 mouse tissues. The resulting data set provides the expression patterns for thousands of predicted genes, as well as known and poorly characterized genes, from mice and humans. We have explored this data set for global trends in gene expression, evaluated commonly used lines of evidence in gene prediction methodologies, and investigated patterns indicative of chromosomal organization of transcription. We describe hundreds of regions of correlated transcription and show that some are subject to both tissue and parental allele-specific expression, suggesting a link between spatial expression and imprinting.
