Description
IL-4d2 is a natural splice variant of IL-4 which lacks the region encoded by the second exon. Numerous recent reports suggested that the expression levels of IL-4d2 change in various diseases, especially those with pulmonary involvement, but the effects of IL-4d2 on the lungs in vivo have never been studied. Replication-deficient adenovirus-mediated gene delivery of mouse IL-4d2 to mouse lungs in vivo was used, and the effects compared with similar adenoviral delivery of mouse IL-4 or with infection with a NULL viral construct.

Description
We inoculated ARPE-19 human retinal pigment epithelial cells with EBOV, and followed course of infection by immunocytochemistry and measurement of titer in culture supernatant. To interrogate transcriptional responses of infected cells, we combined RNA sequencing with in silico pathway, gene ontology, transcription factor binding site and network analyses. Human retinal pigment epithelial cells were permissive to infection with EBOV, and supported viral replication and release of virus in high titer. Unexpectedly, 28% of 560 up-regulated transcripts in EBOV-infected cells were type I IFN responsive, indicating a robust type I IFN response. Overall design: Transcriptomic profiles of ARPE-19 cells 24 hours following infection with EBOV or mock-infection

Description
RATIONALE: Idiopathic pulmonary fibrosis (IPF) is a fatal disease with overtly scarred peripheral and basilar lung regions and macroscopically unaffected central lung areas. OBJECTIVES: To gain better insight into IPF pathobiology by comparing transcriptomic profiles of normal-appearing and scarred regions of IPF lung. METHODS: Lung tissue samples from macroscopically unaffected (normal-appearing, IPFn) and scarred (IPFs) regions of explanted IPF lungs were analyzed by RNASeq and compared with healthy control (HC) lung tissues. RT-qPCR and immunohistochemistry were used to confirm selected findings. MEASUREMENTS AND RESULTS: Numerous previously reported IPF-associated gene expression disturbances as well as additional differentially expressed mRNAs were observed. There were profound transcriptomic changes in IPFn compared with HC tissues, which included elevated expression of extracellular matrix-, immunity- and inflammation-related mRNAs. The magnitude and statistical significance of these changes were comparable or greater than those in the IPFs-to-HC comparison. When directly compared with IPFn, IPFs tissues demonstrated elevated expression of epithelial mucociliary mRNAs. Compared with HC, both IPFn and IPFs tissues demonstrated reduced expression of mRNAs related to solute carrier membrane transport and metabolic processes. Primary fibroblast cultures from IPFn and IPFs tissues were transcriptomically identical. CONCLUSIONS: Macroscopically normal-appearing IPF tissues demonstrate profound disease activity and substantially similar transcriptomic profiles to scarred areas. Differences between these tissues are due to cell types other than fibroblasts and notably include enhanced expression of mucociliary genes in scarred areas. Deranged epithelial homeostasis or possibly non-transcriptomic factors may thus explain the marked architectural differences between normal-appearing and terminally scarred lung in end-stage IPF. Overall design: RNASeq of 26 lung tissue samples from patients with IPF, including affected and unaffected areas of the lung, and from healthy controls

Description
To address the need to study frozen clinical specimens using next-generation RNA, DNA, chromatin immunoprecipitation (ChIP) sequencing and protein analyses, we developed a biobank work flow to prospectively collect biospecimens from patients with renal cell carcinoma (RCC). We describe our standard operating procedures and work flow to annotate pathologic results and clinical outcomes. We report quality control outcomes, nucleic acid yields of our RCC submissions (N=16) to The Cancer Genome Atlas (TCGA) project, as well as newer discovery platforms by describing mass spectrometry analysis of albumin oxidation in plasma and 6 ChIP sequencing libraries generated from nephrectomy specimens after histone H3 lysine 36 trimethylation (H3K36me3) immunoprecipitation. From June 1, 2010, through January 1, 2013, we enrolled 328 patients with RCC. Our mean (SD) TCGA RNA integrity numbers (RINs) were 8.1 (0.8) for papillary RCC, with a 12.5% overall rate of sample disqualification for RIN <7. Banked plasma had significantly less albumin oxidation (by mass spectrometry analysis) than plasma kept at 25°C (P<.001). For ChIP sequencing, the FastQC score for average read quality was at least 30 for 91-95% of paired-end reads. In parallel, we analyzed frozen tissue by RNA sequencing and after genome alignments, only 0.2-0.4% of total reads failed the default quality check steps of Bowtie2, which was comparable to the disqualification ratio (0.1%) of the 786-O RCC cell line, prepared under optimal RNA isolation conditions. The overall correlation coefficients for gene expression between the Mayo Clinic vs. TCGA tissues ranged from 0.75 to 0.82. These data support the generation of high-quality nucleic acids for genomic analyses from banked RCC. Importantly, the protocol does not interfere with routine clinical care. Collections over defined time points during disease treatment further enhance collaborative efforts to integrate genomic information with outcomes. Overall design: Examination of RNA expression in ccRCC

Description
The identification of deregulated microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) in multiple myeloma (MM) has progressively added a further level of complexity to MM biology. In addition, the cross-regulation between lncRNAs and miRNAs has begun to emerge, and theoretical and experimental studies have demonstrated the competing endogenous RNAs (ceRNAs) activity of lncRNAs as natural miRNA decoys in pathophysiological conditions, including cancer. Currently, information concerning lncRNA and miRNA interplay in MM is virtually absent. Herein, we investigated in silico the lncRNA and miRNA relationship in a representative datasets encompassing 95 MM and 30 plasma cell leukemia patients at diagnosis and in four normal controls, whose expression profiles were generated by a custom annotation pipeline to detect specific lncRNAs. We applied target prediction analysis based on miRanda and RNA22 algorithms to 235 lncRNAs and 459 miRNAs selected with a potential pivotal role in the pathology of MM. Among pairs that showed significant correlation between lncRNA and miRNA expression levels, we identified 10 lncRNA-miRNA relationships suggestive of novel ceRNA network with relevance in MM.

Description
Aminaphtone, a drug used in the treatment of chronic venous insufficiency (CVI), showed a remarkable role in the modulation of several vasoactive factors, like endothelin-1 and adhesion molecules. We analysed in vitro the effects of Aminaphtone on whole-genome gene expression. ECV304 endothelial cells were stimulated with IL-1 100 U/ml in the presence or absence of Aminaphtone 6 g/ml. Gene expression profiles were compared at 1, 3, and 6 h after stimulation by microarray.
