Identification of transcripts regulated by CEBPA protein and its P30 isoform in K562

ABSTRACT: To investigate the effect of CEBPA and its mutant isoform P30 on the expression of mRNAs and long non-coding RNAs (lncRNAs), we utilized the K562 AML cell line carrying a stable and Tet-on inducible CEBPA or P30 allele. Based on the expression of known CEBPA transcriptional targets, we selected RNA extracted from 48 hours of induction (CEBPA or P30) together with RNA extracted from control-induced cells (CTR). 2 biological replicates for each sample have been utilized.

Accumulating evidences indicate that different long non-coding RNAs (lncRNAs) might play a relevant role in tumorigenesis, with their expression and function already associated to cancer development and progression. CCAAT/enhancer-binding protein-α (CEBPA) is a critical regulator of myeloid differentiation whose inactivation contributes to the development of acute myeloid leukemia (AML). Mutations in C/EBPα occur in around 10% of AML cases, leading to the expression of a 30-kDa dominant negative ...[more]

Comparative assessment of the transcriptome of pancreatic islets from Non-Obese Diabetic mice in the absence of immune infiltrate

Project description:The transcriptome of pancreatic islets from four mouse strains was compared - NODk.RagKO, B10k.RagKO, NODk.RagKO.insHEL and B10k.RagKO.insHEL. This comparison allows the assessment of altered transcriptome due to two factors - genetic background of NOD vs B10 strain, and the effect of the insHEL transgene. The use of the MHC k haplotype and the RagKO background remove contamination from infiltrating immune cells, in order to obtain a pure islet transcriptome. Three mice of each gentoype were analyzed in this study.

Female mice lacking Xist RNA show partial dosage compensation and survive to term

Project description:X chromosome inactivation (XCI) compensates for differences in X-chromosome number between male and female mammals. XCI is orchestrated by Xist RNA, whose expression in early development leads to transcriptional silencing of one X-chromosome in the female. Knockout studies have established a requirement for Xist, with inviability of female embryos that inherit an Xist deletion from the father. Here, we report that female mice lacking Xist RNA can, surprisingly, develop and survive to term. Xist-null females are born at lower frequency and are smaller at birth, but organogenesis is mostly normal. Transcriptomic analysis indicates significant overexpression of hundreds of X-linked genes across multiple tissues. Therefore, Xist-null mice can develop to term in spite of a deficiency of dosage compensation. However, the degree of X-autosomal dosage imbalance was less than anticipated (1.14- to 1.36-fold). Thus, partial dosage compensation can be achieved without Xist, supporting the idea of inherent genome balance. Nevertheless, to date, none of the mutant mice has survived beyond weaning stage. Sudden death is associated with failure of postnatal organ maturation. Our data suggest Xist-independent mechanisms of dosage compensation and demonstrate that small deviations from X-autosomal balance can have profound effects on overall fitness. RNA-sequencing of tail-tip fibroblasts (TTFs), spleen, liver and heart tissue from Xist-null and control female mice. Sequencing performed with 50nt read length on Illumina HiSeq2000 or 2500. Data consists of 3 biological replicates for TTFs (6 datasets) and 2 biological replicates for tissues (12 datasets).

Transcriptome analysis of khd1-1, spen3-1 and hub1-4 Arabidopsis mutants

Project description:HISTONE MONOUBIQUITINATION1 (HUB1) and its ortholog HUB2 regulate expression of genes involved in flowering, dormancy and circadian clock. HUB1 and HUB2 interact with two RNA-binding proteins KHD and SPEN. Phenotype analysis of the knock-down khd1-1, knock-out spen3-1, and knock-out hub mutants suggested that KHD and SPEN may contribute to flowering- and circadian clock-related functions that are also target of HUB1/2 activity. Transcriptome analysis was performed using RNA extracted from shoot apices of 10-day-old seedlings. After library preparation by TruSeq, RNA was sequenced on the Illumina HiSeq.

RNA-seq of control and CHH (cartilage-hair hypoplasia) fibroblasts transdifferentiated into chondrocytes-like cells

Project description:We used primary human CHH (cartilage-hair hypoplasia) and control fibroblasts in a chondrogenic transdifferentiation model (FDC; fibroblast-derived chondrocytes) to determine the chondrogenic capacity and differential pathway regulation of CHH cells. For the sequencing experiment, dermal fibroblasts from control donors (n=4) and CHH patients (n=4) were isolated from skin biopsies, plated at high density into wells coated with aggrecan, and cultured for three days in an FDC transdifferentiation medium. Total RNA was isolated at three different time points (Day 0, 1, and 3; in total 24 RNA samples), and sequenced using the NextSeq platform (Illumina).

Transcriptome profile of oocytes expressing a catalytically inactive knock-in allele of Ago2

Project description:The RNase III enzyme DICER generates both microRNAs (miRNAs) and endogenous short interfering RNAs (endo-siRNAs). Dicer deletion in mouse oocytes leads to female infertility due to defects during meiosis I. Because miRNA function is suppressed in mouse oocytes, it has been proposed that endo-siRNAs may have a role during female meiosis. By utilizing a catalytically inactive knock-in allele of AGO2 specifically in oocytes, we disrupt the function of siRNAs and analyze the transcriptome of these oocytes in comparison with Ago2 null, and Dicer null oocytes. Germinal vesicle-intact, full-grown oocytes were collected from eCG-primed females expressing a catalytically inactive knock-in allele of Ago2 (Ago2 ADH) specifically in oocytes. Oocytes were also collected from Ago2 null and Ago2 fl/fl oocytes, as well as Dicer wild-type and null mice. Oocytes were freed of attached cumulus cells by pipetting. Twenty oocytes collected from 3 different mice were used for high-throughput RNA sequencing. Three replicates for all genotypes except Ago2 null (two). The mouse background strain is "mostly" C57BL6, i.e., it is a cross between 3 different transgenic mice of different strains.

Global analysis of the RNA-protein interaction and RNA secondary structure landscapes of the Arabidopsis nucleus

Project description:Post-transcriptional regulation in eukaryotes requires cis- and trans-acting features and factors including RNA secondary structure, and RNA-binding proteins (RBPs). However, a comprehensive view of the structural and RBP interaction landscape of RNAs in the nucleus has yet to be compiled for any organism. Here, we use our ribonuclease-mediated structure and RBP binding site mapping approach on Arabidopsis seedling nuclei in vivo to globally profile these features within the nuclear compartment. We reveal opposing patterns of secondary structure and RBP binding levels throughout native messenger RNAs that demarcate alternative splicing and polyadenylation. We also uncover a collection of protein bound sequence motifs, and identify their structural contexts, co-occurrences in transcripts encoding functionally related proteins, and interactions with putative RBPs. Finally, we identify a nuclear role for the chloroplast RBP, CP29A. In total, we provide the first simultaneous view of the RNA secondary structure and RBP interaction landscapes in a eukaryotic nucleus. Protein interaction profile sequencing (PIP-seq) in Arabidopsis seedling nuclei. These are crosslinked with formaldehyde and treated with two RNases (ssRNase and dsRNase) with two replicates

Genome-wide identification of Hfq-regulated small RNAs in the bacterial pathogen Erwinia amylovora

Project description:RNA-seq analysis was performed to examine the sRNA transcripts in wild type E. amylovora 1189 and in the deletion mutant of hfq, at 6 and 12 hours of culture in hrp-inducing minimal medium. Total RNA was isolated from wild type Ea1189, and the hfq mutant of Ea1189, at 6 and 12 hours post inoculation in hrp-inducing minimal medium. RNA transcripts that are between 50-350 nucleotides were analyzed by RNA-seq. Intergenic transcripts whose expression was greatly reduced in the hfq mutant than the wild type at both 6 and 12 hours post inoculation in hrp-inducing minimal medium were selected as potential small RNAs.
