Description
Fifty six genes from DESeq were differentially expressed in the treated versus control samples. More than 20% were related to immune, defense, wounding and inflammatory responses Overall design: Downregulation of REST-003 using siRNAs in MDA-MB-231 cells; we used siRNA against REST-003, as REST-003 may control invasiveness. We transfected si-Control (scramble) or si-REST-003 in MDA-MB-231: duplicate of both (total 4 samples).

Description
The goal of this study was to investigate the role of intragenic CTCF in alternative pre-mRNA splicing through a combined CTCF-ChIP-seq and RNA-seq approach. CTCF depletion led to decreased inclusion of weak upstream exons. Overall design: CTCF ChIP-seq was performed in BJAB and BL41 B cell lines and normalized relative to Rabbit Ig control IP-seq reads. RNA-seq was performed in BJAB and BL41 cells transduced with shRNA against CTCF or RFP as a control, and in untransduced cells as well.

Description
Phosphorus is an essential macronutrient element, but some time causes problems if present in excess. Unlike the enormous molecular and morphophysiological information available in plants regarding phosphate (Pi) deficiency, little is known about the effect of excess Pi on plants, which is indeed essential for its remediation. Here, we have carried out a comparative study of plant molecular responses under excess Pi (20 mM) or without Pi (0 mM) at transcriptome level. The 1.25 mM treatment concentration of Pi used as a control to obtain differentially regulated genes under above mentioned Pi regimes. A novel whole-transcript expression array, i.e. Arabidopsis Gene 1.0 ST Array, was used to perform these experiments. The most distinctly regulated groups of genes represent modulation in ethylene mediated signaling, Fe deficiency response, and root development. We have also identified some defensin like genes, possessing a gibberellic acid regulated domain (GASA like) under excess Pi treatment. Overall, this study will not only help in dissecting the mechanism of plant responses under excess Pi but also provide the clues about the unknown genes involved in phosphorus homeostasis.

Description
Genome-wide transcriptome analysis was carried out in root tissue of Arabidopsis seedlings treated with gold (Au) as Chloroauric acid (HAuCl4). This study demonstrated remarkable changes in root transcriptome within the 12 h exposure. Most of the genes differentially expressed were related to glutathione binding, methylations, secondary metabolism, sugar metabolism, ABA, ethylene, auxin related signalling, transport and signal-transduction pathways.

Description
The specific genes that influence neuroblastoma biology and are targeted by genomic alterations remain largely unknown. We quantified mRNA expression in a highly annotated series of 101 prospectively collected diagnostic neuroblastoma primary tumors and the expression profiles were determined using Affymetrix U95Av2 arrays. Comparisons between the sample groups allow the identification of genes with localized expression patterns. This study demonstrates that the genomic data can be used to subcategorize the disease into molecular subsets and the regional copy number alterations are correlated with a broad number of transcriptional alterations genome wide. This data also suggests that multiple genes from several discrete regions of the human genome co-operate to supress neuroblastoma tumorigenesis and progression.

Description
N1-Methyladenosine (m1A) is a prevalent post-transcriptional RNA modification, yet little is known about its abundance, topol- ogy and dynamics in mRNA. Here, we show that m1A is prevalent in Homo sapiens mRNA, which shows an m1A/A ratio of ~0.02%. We develop the m1A-ID-seq technique, based on m1A immunoprecipitation and the inherent ability of m1A to stall reverse tran- scription, as a means for transcriptome-wide m1A profiling. m1A-ID-seq identifies 901 m1A peaks (from 600 genes) in mRNA and noncoding RNA and reveals a prominent feature, enrichment in the 5'' untranslated region of mRNA transcripts, that is dis- tinct from the pattern for N6-methyladenosine, the most abundant internal mammalian mRNA modification. Moreover, m1A in mRNA is reversible by ALKBH3, a known DNA/RNA demethylase. Lastly, we show that m1A methylation responds dynamically to stimuli, and we identify hundreds of stress-induced m1A sites. Collectively, our approaches allow comprehensive analysis of m1A modification and provide tools for functional studies of potential epigenetic regulation via the reversible and dynamic m1A methylation. Overall design: Identification of m1A sites in human embryonic kidney cells. Comparisons of m1A profiles of wild type HEK293T with ALKBH3 knock out cell line reveals the ALKBH3 specific sites. Stress inducible m1A sites are also identified by comparing the profiles of untreated cells with stress treated cells.

Description
We hypothesize that the observed differences in incidences of pleural and peritoneal malignant mesothelioma (MM) are the result of differences in the direct response of these cell types to asbestos rather than to differences mediated by the in vivo microenvironment. To test this hypothesis, we characterized cellular responses to asbestos in a controlled environment using high-throughput RNA sequence and other assays. Overall design: Examination of asbestos-treated versus untreated mesothelial cells from four cell lines representing two tissue types in culture.

Description
Purpose: Single cell RNA-seq could observe heterogeneity of cell transcriptomes. The goals of this study are to compare the changes of ESCC cell line KYSE-180 RNA profiles in response to different doses of radiotherapy and to analyze the radio-resistance related genes. Overall design: Methods: Cultured KYSE-180 cells accepted accumulative irradiation doses of 0 Gy, 12 Gy or 30 Gy, respectively. Single cell libraries were generated by Smart-seq 2 kit, sequenced using Illumina HiSeq 2500. The sequence reads that passed quality filters were analyzed at the transcript expression level with TopHat followed by DESeq2/Monocle.
