Description
Purpose: Next-generation sequencing (NGS) has been used to study the gene expression in different samples under air and ethylene treatment. The goal of this study is to uncover how ENAP1 and H3K23Ac dynamically coordinate with EIN3 to regulate gene expression in response to ethylene. Overall design: Whole seedling mRNA profiles of 3-day old ein2, ein3eil1, ENAP1ox/ein2 and ENAP1ox/ein3eil1 (in COL background) were generated by sequencing, in 2 replications, using Illumina HiSeq 2000

Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
BP and ER encode proteins that act synergistically to regulate Arabidopsis inflorescence architecture. To search for genes/proteins that influence the BP/ER signaling pathways, we conducted mutagenesis of the bp er double mutant and found that a mutation in FILAMENTOUS FLOWER (FIL) suppresses many of the morphological/developmental defects in bp er. Given that FIL encodes a Zn-finger containing transcription factor, microarray analysis was conducted on bp er vs. the bp er fil line to identify genes that are misregulated and which might implicate specific genes/proteins/pathways that are involved in regulating inflorescence development.

Description
COHCAP (City of Hope CpG Island Analysis Pipeline) is an algorithm to analyze single-nucleotide resolution DNA methylation data. It provides QC metrics, differential methylation for CpG Sites, differential methylation for CpG Islands, integration with gene expression data, and visualization of methylation values. COHCAP is currently the only DNA methylation package that can handle integration with gene expression data, and the results of this study show that COHCAP can identify regions of differential methylation with ~50% concordance with gene expression. COHCAP is scalable for analysis of both cell line data and heterogeneous patient data, and it can identify known cancer biomarkers as well as intriguing new roles of epigenetic regulation in cancer (such as methylation of estrogen receptor in breast cancer patients). This study also uses cell line data to show that COHCAP is capable of analyzing Illumina methylation array and targeted bisulfite sequencing data, with either 1-group or 2-group study designs. The accuracy of COHCAP is accessed using qPCR, EpiTect, and comparison of COHCAP regions of differential methylation with MIRA peaks. This software is freely available at https://sourceforge.net/projects/cohcap/.

Description
Long terminal repeat (LTR) elements are wide-spread in the human genome and have the potential to act as promoters and enhancers. Their expression is therefore under tight epigenetic control. We previously reported that a member of the THE1B class of LTR elements in classical Hodgkin Lymphoma (cHL) acted as a promoter for the growth factor receptor gene CSF1R and that expression of this gene is required for tumor survival. However, to which extent and how such elements participate in globally shaping the unique cHL gene expression program is unknown. To address this question we mapped the genome-wide activation of THE1-LTRs in cHL cells using a targeted next generation sequencing approach (RACE-Seq). Integration of these data with global gene expression data from cHL and control B cell lines showed a unique pattern of LTR activation impacting on gene expression, including genes associated with the cHL phenotype. We also show that global LTR activation is induced by strong inflammatory stimuli. Together these results demonstrate that LTR activation provides an additional layer of gene deregulation in classical Hodgkin lymphoma and highlight the potential impact of genome-wide LTR activation in other inflammatory diseases. Overall design: RNA-Seq in laser capture microdissected (LCM) tumour (TU) and non tumour cells (NTC) primary HL material from patient samples

In this report, Tompkins et al describe the derivation, differentiation stage-specific purification, and genome-wide analysis of cardiomyocytes derived from hESCs. Key features of the molecular programs that define human cardiac muscle cell differentiation were described and researchers observed that cells may harbor epigenetic DNA methylation “memories” that reflect the gene activation history of important developmental genes. Overall design: For RNA-seq. Cardiomyocyte differentiation from human embryonic stem cells (H7). 11 time point pilot time series. D3 and D4 samples FACS sorted for primitive and cardiac mesoderm isolation, respectively. Data from negatives sorts (minus) included as well.

Description
CC-671 has been identified as an inhibitor of Cdc2-like kinase 2 (CLK2) and TTK in direct enzyme assays. CLK2 is a member of the CLK family that phosphorylates serine- and arginine-rich (SR) proteins of the spliceosomal complex as part of a regulatory mechanism for control of pre-mRNA splicing. SR proteins are a family of small nuclear ribonucleoprotein particle (snRNP) splicing factors involved in constitutive and alternative splicing. Monitoring specific phospho-biomarkers of CLK2 demonstrated that CC-671 inhibited phosphorylation of CLK2 substrates in cancer cells with mean IC50 of 549 nM in the triple negative breast cancer (TNBC) line CAL51. In this study, RNA sequencing approach was used to quantify the impact of CC-671 treatment on gene transcription and global alternative splicing in CAL51 cells. Differential exon usage analysis demonstrated that CC-671 changed alternative splicing of many genes. In addition, different sets of genes are impacted by CC-671 at both the alternative splicing and mRNA expression. Genes impacted by alternative splicing shared a set of common pathways with genes altered by mRNA expression. This result indicates that CC-671 regulates transcription via both gene expression and alternative splicing mechanisms. Overall design: Triple negative breast cancer (TNBC) line CAL51 was grown in DMEM medium containing 10% fetal bovine serum, as recommended by vendor. The growing cells were treated by CC-671 in three biological replicates at the following concentrations and time intervals. The treatment time points were 6 hour and 24 hour. Concentration of compounds used was 3 and 10 uM. Six million cells from each treatment were harvested and RNA was isolated by RNeasy kit. Poly-A selection and strand-specific RNA library construction were performed, followed by multiplexing indexed libraries and sequencing on the HiSeq 2500 with 2x100 bp read lengths. A total of 16 samples were included in this experiment, including 4 treatment groups with three biological replicates and 2 vehicle control groups with two biological replicates
