Short and Long RNA sequencing of human mature erythrocytes

ABSTRACT: We employed high-throughput sequencing of both short (~18-24nt) and long (>200nt) RNAs in human erythrocytes. We obtained blood from five healthy individuals for the short (small) RNA-seq library preparations and blood from three individuals for the long RNA-seq library preparations. We identified an abundant, diverse population of RNAs. Both polyadenylated and nonpolyadenlated long RNAs were identified. Additionally, known and novel microRNAs were identified in the short RNA dataset using the probabalistic modeling algorithm miRDeep. These RNAs lend insight into erythrocyte biology and provide utility as potential biomarkers. To determine both shared and unique aspects of the erythrocyte long RNA transcriptome, we compared this transcriptome with that of the PBMC and CD34+ erythroid progenitor transcriptomes.

<h4>Background</h4>Human erythrocytes are terminally differentiated, anucleate cells long thought to lack RNAs. However, previous studies have shown the persistence of many small-sized RNAs in erythrocytes. To comprehensively define the erythrocyte transcriptome, we used high-throughput sequencing to identify both short (18-24 nt) and long (>200 nt) RNAs in mature erythrocytes.<h4>Results</h4>Analysis of the short RNA transcriptome with miRDeep identified 287 known and 72 putative novel microRNA ...[more]

Deciphering the RNA landscape by RNAome sequencing [Seq]

Project description:Current RNA expression profiling methods rely on enrichment steps for specific RNA classes, thereby not detecting all RNA species in an unperturbed manner. We report strand-specific RNAome sequencing that determines expression of small and large RNAs from ribosomal RNA-depleted total RNA in a single sequence run. Since current analysis pipelines cannot reliably analyze small and large RNAs simultaneously, we developed TRAP, Total Rna Analysis Pipeline, a robust interface that is also compatible with existing RNA sequencing protocols. RNAome sequencing quantitatively preserved all RNA classes, allowing cross-class comparisons that facilitates the identification of relationships between different RNA classes. We demonstrate the strength of RNAome sequencing in mouse embryonic stem cells treated with cisplatin. MicroRNA and mRNA expression in RNAome sequencing significantly correlated between replicates and was in concordance with both existing RNA sequencing methods and gene expression arrays generated from the same samples. Moreover, RNAome sequencing also detected additional RNA classes such as enhancer RNAs, anti-sense RNAs, novel RNA species and numerous differentially expressed RNAs undetectable by other methods. At the level of complete RNA classes, RNAome sequencing also identified a specific global repression of the microRNA and microRNA isoform classes after cisplatin treatment whereas all other classes such as mRNAs were unchanged. These characteristics of RNAome sequencing will significantly improve expression analysis as well as studies on RNA biology not covered by existing methods. 8 mouse embryonic stem cell samples, 4 control and 4 cisplatin treated, 4 replicates per group for Affymetrix arrays. Of these, 6 were used for sequencing and are reported in this Series.

HuR- dependent regulation of mRNA splicing is essential for the B cell antibody response [RNA-Seq]

Project description:Post-transcriptional regulation of mRNA by the RNA binding protein HuR is required in B cells for the germinal centre reaction and for the production of class-switched antibodies in response to T-independent antigens. Transcriptome-wide examination of RNA isoforms, abundance and translation in HuR-deficient B cells, together with direct measurements of HuR-RNA interaction, revealed that HuR-dependent mRNA splicing affects hundreds of transcripts including the dihydrolipoyl succinyltransferase (Dlst), a subunit of the aketoglutaratedehydrogenase (aKGDH) enzyme. In the absence of HuR, defective mitochondrial metabolism results in high levels of reactive oxygen species and B cell death. Our study shows how post-transcriptional processes control the balance of energy metabolism required for B cell proliferation and differentiation. Sequencing analysis of B cell transcriptome using Illumina TruSeq mRNA sample prep kit and Illumina platform. RNA was isolated from ex-vivo or LPS-activated (48h) splenic B cells from HuRflox/flox x mb1wt control or HuRflox/flox x mb1cre mice. 3-4 biological replicates per genotype and condition.

The miR-155/PU.1 axis acts on Pax5 to enable efficient terminal B cell differentiation [RNA-Seq]

Project description:miR-155 inhibits PU.1 expression, leading to the initiation of the initiation of plasma cell differentiation pathway. Additional PU.1 targets include a network of genes whose products are involved in adhesion, with direct links to B:T interactions. Sequencing analysis of B cell transcriptome using Illumina TruSeq mRNA sample prep kit and Illumina platform. RNA was isolated from ex-vivo LPS and IL-4 activated (96h) splenic B cells from wild type, PU.1[155-/155-] and miR-155[-/-] mice. 4-5 biological replicates per genotype and condition.

RNA-seq expression profiling of OCI-AML2 and OCI-AML3 cells upon CRISPR/Cas9 –mediated disruption of DDX3X RNA binding domain

Project description:Human acute myeloid leukemia cell lines OCI-AML2 and OCI-AML3 were used in a CRISPR/Cas9-mediated approach to specifically target DDX3X’s gene sequences encoding the RNA binding domain of the helicase. DDX3X RNA binding domain is bipartite in the two halves of the helicase core. sgRNAs were designed to target both halves of the domain (named RNA binding domain A and B – RBDA and RBDB). We performed RNA-seq to observe the gene expression changes in both OCI-AML2 and OCI-AML3 cell lines following the not-combined CRISPR/Cas9 –mediated targeting of both regions of the DDX3X RNA binding domain. Control CRISPR/Cas9 performed with no sgRNA expressing vector (named “empty vector”) was performed in both cell lines. The latter condition was used as a control for gene expression changes analysis, for each cell line.

Identification of dysregulated genes after deletion of miR-1-1 and miR-1-2

Project description:Purpose: The goals of this study are to identify dysregulated mRNAs in the heart after deletion of miR-1-1 and miR-1-2. Methods: Total RNAs were extracted from hearts at embryonic E15.5 (E15.5) or postnatal 2.5 days (P2.5) of miR-1s dHET and miR-1s dKO mice. mRNAs were purified using a poly-A selection approach and sequenced using Illumina HiSeq 2000. The sequence reads were aligned to the mouse reference genome (NCBI Build 37/mm9) using TopHat program (Bowtie algorithm). Transcript assembles and identification of differentially expressed genes were achieved using Cufflinks package. To account for expression bias due to transcript length, each sample transcript expression was normalized by using cufflinks algorithm with a FDR of 0.05. Results: Using 1.5-fold change as a cutoff, 997 and 653 transcripts were found to be upregulated and downregulated, respectively, in miR-1s dKO heart at P2.5. 423 transcripts were found to be upregulated and 653 were down-regulated in miR-1s dKO heart at E15.5. Many upregulated genes are directly involved in a fetal gene program. Conclusions: miR-1 directly represses a fetal gene program. We performed RNA deep-seq using postnatal 2.5 days (P2.5) heart from miR-1-1 and miR-1-2 double knockout mice and compared it to that of littermate control.

Project description:We specifically deleted Baf250a in the SAN by using Hcn4-CreERT2 mice. We performed mRNA-seq to identify dysregulated genes in the SAN after deletion of Baf250a. To identify direct targets of Baf250a and sequential transcriptional events after deletion of Baf250a in the SAN, we performed mRNA-seq at 6 time points. i.e. 0 hr (tamoxifen treatment), 16 hr after tamoxifen treatment, 20 hr, 24 hr, 48 hr, and 6 days after tamoxifen treatment. mRNA-seq were performed at 0 hr, 16 hr, 20 hr, 24 hr, 48 hr, and 6 days after tamoxifen treatment.
