Affymetrix Wheat Genome Array (wheat)
Description
Alloplasmic lines provide a unique tool to study the nucleo-cytoplasmic interactions. Alloplasmic lines T183 and T195 were developed through the introgression of the cytoplasm from Aegilops uniaristata (T183) and Aegilops squarrosa (T195) in the nuclear background of Triticum aestivum cv. Chris. Alloplasmic line TH237 was produced introgressing the Hordeum chilense accession H7 cytoplasm into the nuclear background of Triticum aestivum accession T20. Fifty seeds for each sample in pots of 11 cm diameter and grown in controlled conditions under 600E m-2 s1 high light intensity in a daily regime of 12 h light at 22C and 12 h darkness at 15C. Plants were bulked from each pot and three biological replicate used for the transcriptomics Fully expanded second leaves were collected two weeks from sowing in the middle of the light period and used for transcriptomic analysis.

Illumina HiSeq 2500
Description
Using RNA-sequencing analysis of peripheral blood cells from 11 cervical cancer patients, 21 cervical intraepithelial neoplasia patients and 19 healthy controls, we identified a group of differentially expressed genes. A real time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was applied to the validation of candidate markers in the blood of 115 patients and 46 healthy controls. The results suggest that a six-gene predictor set (GZMB, NDUFA1, GPR84, NUAK1, AGAP1 and CIR1) can be used as candidate genes for the detection of cervical cancer. Overall design: The mRNA profiles of peripheral blood cells from 11 cervical cancer patients, 21 cervical intraepithelial neoplasia patients and 19 healthy control participants were sequenced using Illumina 2500.

Description
RNA-Seq analysis was performed to assess how a glucose-supplemented diet and/or a hyl-2 mutation altered the transcriptome. Comparison analysis of transcripts associated with anoxia sensitive animals (hyl-2(tm2331) mutation or a glucose diet) revealed 199 common transcripts encoded by genes with known or predicted functions involving innate immunity, cuticle function (collagens) or xenobiotic and endobiotic phase I and II detoxification system. Overall design: mRNA profiles of OP50-fed C. elegans, glucose-fed C. elegans (N2 strain), OP50-fed C. elegans altered in ceramide metabolism (due to a hyl-2(tm2031) mutation), and glucose-fed C. elegans altered in ceramide metabolism were generated by RNA-Seq, in triplicate, using an Illumina HiSeq2000. Transcriptome data were then used for a comprehensive quantitative analysis of differential gene regulation in hyl-2(tm2031) and glucose-fed C. elegans.

Description
Purpose: We aimed to identify ZAT18 target genes and characterize functions of ZAT18 during plant drought tolerance Methods: A total amount of 3 µg RNA was used for generation of sequencing libraries using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) following manufacturer’s recommendations and index codes were added to attribute sequences to each sample. After cluster generation, the library preparations were sequenced on an Illumina Hiseq platform and 125 bp/150 bp paired-end reads were generated. Clean reads were obtained by removing low quality reads, reads containing adapter and ploy-N from raw data. At the same time, Q20, Q30 and GC content the clean data were calculated. Index of the Arabidopsis genome was built using Bowtie v2.2.3 and paired-end clean reads were aligned to the reference genome using TopHat v2.0.12. HTSeq v0.6.1 was used to count the reads numbers mapped to each gene. And then FPKM (Fragments Per Kilobase of transcript sequence per Millions base pairs sequenced) of each gene was calculated based on the length of the gene and reads count mapped to this gene. Differential expression analysis of drought stress versus control condition was performed using the DESeq R package (1.18.0). Results:In total, eight samples with two biological replicates per genotype/treatment combination were used for RNA sequencing analysis. At least 2 G clean bases were generated for each sample. Comparative analysis revealed that 1777 genes were transcriptionally affected by AtZAT18 trasngene or drought treatment. The results showed that overexpression of AtZAT18 modulated expression level changes of 423 and 561genes under control and drought stress conditions, respectively. Drought stress treatment changed expression of 971 genes with 768 up-regulated and 203 down-regulated. Overall design: In this study, wild type Arabidopsis and two lines of AtZAT18 transgenic plants were grown in moist soil for 7 days. Drought stress was imposed by withholding water for 10 days. The rosette leaves of control and drought treated Col-0 and AtZAT18 transgenic plants were then collected for RAN isolation. AtZAT18 transgenic plant and Col WT were used by deep sequencing, in duplicate

Description
Rationale: Despite shortening vasopressor use in shock, hydrocortisone administration remains controversial, with potential harm on the immune system. Few studies assessed hydrocortisone impact on the transcriptional response in shock, and we are lacking data in burns. Objectives: To assess the hydrocortisone-induced transcriptional modulation in severe burn shock, particularly on the immune response. Methods: We collected whole blood samples (n= 117) during a randomized controlled trial assessing the efficacy of hydrocortisone administration on burn shock. Using whole genome microarrays, we first compared burn patients from the placebo group (n=15) to healthy volunteers (n=13) to describe the transcriptional modulation induced by burn shock over the first week. Then we compared burn patients randomized for either hydrocortisone administration (n=15) or placebo (n=15) to assess hydrocortisone-induced modulation. Measurements and Main Results: Study groups were similar in terms of severity and major outcomes, but shock duration (significantly reduced in the hydrocortisone group). Many genes (n=2250) were differentially expressed between burn patients and healthy volunteers, with 85% of them exhibiting a profound and persistent modulation over seven days. Interestingly, we showed that hydrocortisone enhanced the shock-associated repression of adaptive, but also innate immunity. Conclusions: We found that the initial host response to burn shock encompasses a wide and persistent modulation of gene expression, with profound modulation of pathways associated with metabolism and immunity. Importantly, hydrocortisone administration may worsen the immunosuppression associated with severe injury. These data should be taken into account in the risk ratio of hydrocortisone administration in patients with inflammatory shock.

Although many protein-coding genes have been identified to be aberrantly expressed in gallbladder cancer, the mechanism that account for the development and progression of gallbladder cancer remains unclear. In recent years, long noncoding RNAs have been shown to play vital roles in mammalian cell biology. In this study, we found that a small number of lncRNAs that are aberrantly expressed.
