Description
By transcriptome (RNA-Seq) analysis of PC-3 or DU145 prostate cancer cell lines over- or under-expressing NUSAP1, we determined genes that become differentially expressed upon expression changes of NUSAP1. Ingenuity Pathway Analysis revealed that the differentially expressed genes correlated with increased tumor progression and are involved in functions that include cancer, cellular movement, and cell morphology Overall design: Lentiviral infections were used to over- or under-express NUSAP1 or controls in triplicate in PC-3 or DU145 cell lines. Seventy-two or ninety-six hours after infection, total RNA was extracted and purified. The sequencing libraries were prepared with the TruSeq RNA Sample Preparation Kit v2 (Illumina) or TruSeq Stranded mRNA Sample Preparation Kit (Illumina) as directed by the manufacturer’s protocol. Pooled libraries were run on a Hiseq 2000 Sequencing System (Illumina) with 101 base pair single-end reads.

Understanding the mechanism of low temperature (LT) adaptation is crucial to the development of cold-tolerant crops. To identify the genes involved in the development of LT tolerance in the crown of hexaploid wheat we examined the global changes in genes expression during cold-treatment using the Affymetrix Wheat Genome Chip.

Description
Genome-wide mRNA expression profiling was performed in AGS, gastric cancer cell line, upon miR-25 silencing. At 48 hours upon anti-miR-25-3p (miRNA inhibitor) and non-targeting control RNA transfection, the whole transcriptome profiling was performed in triplicates. The miR-25 silencing elevates the diffuse gastric cancer features like expression of COL1A2, expression of COL1A2 co-expressed genes, Epithelial to Mesenchymal Transition (EMT) and angiogenesis associated genes.

Description
We investigated the specificity profiles of a variety of RNA guided adenosine deaminases while exploring roles of NLS/NES and hyperactive mutants via analysis of the transcriptome-wide off-target A->G editing effected by these tools. To this end, HEK 293T cells were transfected with each construct and analyzed by RNA-seq. Untransfected cells were included as controls. From each sample, we collected ~40 million uniquely aligned sequencing reads. We then used Fisher's exact test to quantify significant changes in A->G editing yields, relative to untransfected cells, at each reference adenosine site having sufficient read coverage. The number of sites with at least one A->G editing event detected in any of the samples was computed. Overall design: Study of transcriptome wide A->G off-targets arising due to the overexpression of a variety of RNA guided adenosine deaminases.

Description
Metastasis-initiating cells dynamically adapt to the distinct microenvironments of different organs, but these early adaptations are poorly understood due to the limited sensitivity of in situ transcriptomics. We developed fluorouracil-labeled RNA sequencing (Flura-seq) for in situ analysis with unprecedented sensitivity. Flura-seq utilizes cytosine deaminase (CD) to convert fluorocytosine to fluorouracil, covalently labeling nascent RNA for purification and sequencing. Flura-seq revealed that breast cancer micrometastases in lung and brain exhibit unique, reversible gene signatures depending on the microenvironment. Specifically, the mitochondrial electron transport Complex I and the NRF2-driven antioxidant programs were induced in oxygen-rich pulmonary micrometastases, compared to mammary tumors or brain micrometastases. Loss of Complex I activity, and antioxidant supplementation potentiated pulmonary metastatic growth. We confirm lung metastasis-specific NRF2 overexpression in clinical samples, thus validating Flura-seq's utility in identifying clinically actionable microenvironmental adaptations in early metastasis. The sensitivity, robustness and economy of Flura-seq are broadly applicable beyond cancer research. Overall design: Examination of 5-FU labeled RNAs in cancer cells present in different organs

Description
The objective of the study was to compare the wound macs with corresponding macs derived from peripheral blood monocytes (MDMs). Wound site macrophage (wound macs were isolated from human subjects with chronic wounds. Matching blood monocyte derived macrophages (MDM) were obtained from same subjects. Transcriptome profiling (GeneChip, Affymetrix) was performed.The expression values of genes were normalized using global scaling approach.

Description
Surgical interventions on blood vessels bear a risk for intimal hyperplasia and atherosclerosis as a consequence of injury. A specific feature of intimal hyperplasia is the loss of vascular smooth muscle cell (VSMC) differentiation gene expression. We hypothesized that immediate responses following injury induce vascular remodeling. To differentiate injury due to trauma, reperfusion and pressure changes we analyzed vascular responses to carotid artery bypass grafting in mice compared to transient ligation. As a control, the carotid artery was surgically laid open only. In both, bypass or ligation models, the inflammatory responses were transient, peaking after 6h, whereas the loss of VSMC differentiation gene expression persisted. Extended time kinetics showed that transient carotid artery ligation was sufficient to induce a persistent VSMC phenotype change throughout 28 days. Transient arterial ligation in ApoE knockout mice resulted in atherosclerosis in the transiently ligated vascular segment but not on the not-ligated contralateral side. The VSMC phenotype change could not be prevented by anti-TNF antibodies, Sorafenib, Cytosporone B or N-acetylcysteine treatment. Surgical interventions involving hypoxia/reperfusion are sufficient to induce VSMC phenotype changes and vascular remodeling. In situations of a perturbed lipid metabolism this bears the risk to precipitate atherosclerosis. Overall design: Comparison of mRNA changes between control tissue and bypass grafts perfused for 1, 6 and 24h. Number of replicated per group =4-5

Description
Carcinoma associated fibroblasts (CAFs) have recently been implicated in important aspects of epithelial solid tumor biology such as neoplastic progression, tumor growth, angiogenesis, and metastasis. However, neither the source of CAFs nor the differences between CAFs and fibroblasts from non-neoplastic tissue have been well defined. In this study we demonstrate that human bone marrow-derived mesenchymal stem cells (hMSCs) exposed to tumor-conditioned medium (TCM) over a prolonged period of time assume a CAF-like myofibroblastic phenotype. More importantly, these cells exhibit functional properties of CAFs including sustained expression of stromal derived factor 1 (SDF-1) and the ability to promote tumor cell growth both in vitro and in an in vivo co-implantation model and expression of myofibroblast markers including -smooth muscle actin and fibroblast surface protein. hMSCs induced to differentiate to a myofibroblast-like phenotype using 5-azacytidine do not promote tumor cells growth as efficiently as hMSCs cultured in tumor-conditioned medium nor do they demonstrate increased SDF-1 expression. Furthermore, gene expression profiling revealed similarities between TCM exposed hMSCs and carcinoma associated fibroblasts. Taken together these data suggest that hMSCs are a source of carcinoma associated fibroblasts and can be used in the modeling of tumor-stroma interactions. To our knowledge this is the first report demonstrating that hMSCs become activated and resemble carcinoma associated myofibroblasts upon prolonged exposure to conditioned medium from MDAMB231 human breast cancer cells.
