Project description:Purpose: The purpose of this RNA Sequencing project was to investigate the transcriptional regulatory relationship between NF-YC3/4/9 and HY5 Methods: Total RNA was isolated, and then poly-A purified. 100ng of starting RNA was used to generate RNASeq libraries using the NEXTflex Illumina qRNA-Seq Library Prep Kit, and sequenced on an Illumina HiSeq2500 machine. Results: NF-YC3/4/9 and HY5 have both shared and independent regulatory targets. Overall design: mRNA profiles of 7-day old Wild Type (WT), nf-yc triple (Q3), hy5, and nf-yc triple hy5 (Q3hy5) seedlings grown in continuous white light were generated from two biological replicates through paired end deep sequencing on an Illumina HiSeq2500 platform.
Project description:MicroRNAs (miRNAs) are small (~22 nucleotide) noncoding RNAs that play pivotal roles in regulation of gene expression. The value of miRNAs as circulating biomarkers is now broadly recognized; such tissue-specific biomarkers can be used to monitor tissue injury and several pathophysiological conditions in organs. In addition, miRNA profiles of normal organs and tissues are important for obtaining a better understanding of the source of modulated miRNAs in blood and how those modulations reflect various physiological and toxicological conditions. This work was aimed at creating an miRNA atlas in rats, as part of a collaborative effort with the Toxicogenomics Informatics Project in Japan (TGP2). We analyzed genome-wide miRNA profiles of 55 different organs and tissues obtained from normal male rats using miRNA arrays. The work presented herein represents a comprehensive dataset derived from normal samples profiled in a single study. Here we present the whole dataset with miRNA profiles of multiple organs, as well as precise information on experimental procedures and organ-specific miRNAs identified in this dataset. miRNA expression in rat various organs was measured with or without saline perfusion. 3 animals were used.
Project description:Preoperative chemoradiotherapy (CRT) followed by surgery has been proved to improve esophageal squamous cell carcinoma (ESCC) patients’ survival in comparison with surgery alone. However, the outcomes of CRT are heterogeneous, and no clinical or pathological method could predict CRT response. We aim to identify miRNA markers for ESCC CRT-response prediction through miRNA expression analyses. MiRNA expression analyses were performed on pretreatment cancer biopsies from 28 ESCCs who received neoadjuvant CRT and surgery using Agilent human miRNA microarrays based on miRBase (release 18.0) GeneChip®.
Project description:To identify the direct target of miR-490-3p, we used whole genome microarray expression profiling to screen for genes potentially regulated by the microRNA. AGS cells were transfected with control mimics or miR-490-3p mimics and gene expression was determined 72 hours after transfection.
Project description:ASF1 is a conserved histone chaperone with affinity to histone H3-H4. Arabidopsis thaliana genome encodes two ASF1 homologues, which play redundant roles in S-phase progression and cell proliferation in plant development. Here, in an attempt to obtain the knowledge of ASF1 role in transcriptional regulation, we perform the transcriptome analysis of each asf1 single mutant (Atasf1a and Atasf1b) as well as Atasf1ab double mutant in comparison with wild type (WT). 12-day-old seedlings of wild-type (WT), each single mutants and double mutant grown in normal growth condition were used for RNA extraction and microarray. Duplicate samples were analyzed.
Project description:To investigate the potential role of peptidylarginine deiminase 2 (PAD2) in gene expression, we created stable shRNA scrambled control and PAD2 knockdown MCF-7 breast cancer cell lines. After validating the specific knockdown of PAD2 at the mRNA and protein level, we utilized an Agilent microarray platform to compare the gene expression profile of the two cell lines to generate a candidate list of genes regulated by PAD2. Control and PAD2 knockdown cells were created by stably transfecting shRNA constructs into MCF-7 cells. Stable cells were selected using puromycin and knockdown validate at the mRNA and protein level. Microarray data represents 4 independent biological replicates contain control and PAD2 knockdown samples.
Project description:To determine the functional relevance of the HY5 binding sites to the transcriptional regulation, we performed genome wide expression analysis using WT and hy5 grown in continuous white light for 4 days. Keywords: mutant/widetype comparative Overall design: For this analysis, we used 70mer oligo microarray that covers 25,676 unique genes (Ma et al. 2005). Four biological replicate experiments were done with dye-swap design.
Project description:A comparative study to determine the pepper leaf curl virus resistance machanism between resistant and susceptible genotypes at three leaf stage. To study the molecular mechanism of pepper leaf curl virus (PepLCV) resistance, pepper plants were exposed to PepLCV through artificial inoculation and hybridization on Agilent tomato microarrays. The expression analysis of PepLCV resistant and susceptible genotypes after artificial inoculation at three leaf stage showed that the resistance against PepLCV is due to sum of expression of hundreds of genes at a particular stage. Tomato microarrays consisting of 43,803 probes were used for whole genome expression analysis of chilli peppers for resistance against PepLCV. Transcripts from the leaves of resistant (BS-35) and susceptible plants (IVPBC-535) were compared in response to PepLCV inoculation at three leaf stage.
