SRp20 regulates Genome-wide Alternative RNA splicing events in MEF3T3 cells

ABSTRACT: To examine the effects of SRp20 on genome-wide RNA splicing in mouse cells, we utilized Exonhit SpliceArrayTM to compare genome-wide changes of RNA splicing and transcription in MEF3T3 mouse fibroblasts with or without ectopic expression of SRp20. MEF3T3 tet-off cells were transfected with pRevTRE/T7-SRSF3 expression vector (pJR17) or pFLAG-CMV5.1 empty vector, each performed in triplicate. A mouse genome-wide splice-array assay was performed by using a service provider ExonHit Therapeutics, Inc (Gaithersburg, MD). Fifty ng of total RNA isolated from MEF3T3 cells with or without SRp20 overexpression was quality controlled and analyzed by using Affymetrix GeneChip platform.

SRp20 regulates Genome-wide Alternative RNA splicing events in U2OS cells

Project description:To examine the effects of SRp20 on genome-wide RNA splicing in tumor cells, we utilized Exonhit SpliceArray to compare genome-wide changes of RNA splicing and transcription in U2OS cells with or without knockdown of SRp20 by RNAi. U2OS cells were treated by SRp20 siRNA or non-specific siRNA, each performed in triplicate. A human genome-wide splice-array assay was performed by using a service provider ExonHit Therapeutics, Inc (Gaithersburg, MD). Fifty ng of total RNA isolated from U2OS cells with or without knockdown of SRp20 was quality controlled and analyzed by using Affymetrix GeneChip platform to profile the expression of 20,649 genes and splicing events of 19,066 genes.

Genome-wide analysis of novel splice variants induced by topoisomerase I poisoning shows preferential occurrence in genes encoding splicing factors

Project description:Topoisomerase I (Top1) relaxes both positive and negative supercoilings by producing transient Top1 cleavage complexes (Top1cc). Several studies have suggested the implication of Top1 in splicing. Here, we tested the implication of Top1cc in splicing at the global genome level in human carcinoma cells to determine whether Top1 inhibition selectively affects particular families of genes. We tested the impact of Top1 inhibition on splicing at the genome-wide level in human colon carcinoma HCT116 cells. The RNA of HCT116 cells treated with camptothecin (CPT) for various times was analyzed with ExonHit Human Splice Array.

A splice isoform signature of ParkinsonM-bM-^@M-^Ys disease in peripheral blood

Project description:In these studies, we used splice variant-specific microarrays manufactured by the ExonHit company ( www.exonhit.com) on the Affymetrix platform. The goal was to identify splice isoforms whose expression is altered in whole blood of early-stage ParkinsonM-bM-^@M-^Ys disease patients compared to healthy and neurodegenerative disease controls. The study included 19 cases of ParkinsonM-bM-^@M-^Ys disease (PD) samples, 4 of multiple system atrophy (MSA), 4 progressive supranuclear palsy (PSP) and 10 healthy controls. Thirteen splice variants were confirmed in quantitative polymerase chain reactions and used to classify blinded samples from ParkinsonM-bM-^@M-^Ys disease patients and controls with 90% accuracy and 94% sensitivity. In these studies, we used splice variant-specific microarrays manufactured by the ExonHit company ( www.exonhit.com) on the Affymetrix platform. The study included 19 cases of ParkinsonM-bM-^@M-^Ys disease (PD) samples and 20 control samples including 4 cases of multiple system atrophy (MSA), 4 progressive supranuclear palsy (PSP) and 12 healthy controls. Splice isoforms differentially expressed in PD vs any other control group were identified and validated using real-time quantitative PCR on two independent sets of 33 coded and 53 blinded samples.

Alternative splicing signatures in apoptosis related genes of human HeLa cells with RNAi targeting p68 RNA helicase-DDX5

Project description:Alternative splicing profiling of apopotosis related genes in human HeLa cells (cervical cancer cell line) transfected with a plasmid expressing shRNAs targetting p68 helicase (DDX5, DEAD (Asp-Glu-Ala-Asp) box polypeptide 5) cloned into the pSuper expression vector compared to empty vector. Keywords: treated vs. untreated comparison; alternative splicing Two-condition experiment, where the p68 DDX5 gene product levels was inhibited by siRNA transfection and compared to transfection with the negative control (scrambled siRNA). Biological replicates: 2, all independently grown and harvested. A dye swapping technical duplicate was performed for each biological replicate. Samples were hybridized onto a 44290 feature array designed by ExonHit to detect splicing events in apopotosis related genes and manufactured by Agilent using in situ synthesis of oligonucleotides by SurePrint technology.

RNAi profiling by array of mouse P19 cells to investigate how SR proteins coordinate gene expression programs

Project description:Members of the SR protein family of RNA binding proteins play numerous roles in gene expression, including the regulation of pre-mRNA splicing, mRNA export, and translation. How SR proteins coordinate gene expression programs has been largely unexplored, and comprehensive knowledge of endogenous mRNA targets is lacking. Gene expression changes upon SRp20 or SRp75 RNAi in P19 parental, SRp75-BAC, and SRp20-BAC cells were measured with mouse whole genome microarrays. The knockdown of either SRp20 or SRp75 led to up- or downregulation of specific transcripts. Phenotypic rescue in the SRp75-BAC, and SRp20-BAC cells demonstrated functionality of the GFP-tagged SR proteins, and showed the specificity of the knockdowns.

shRNA mediated knockdown of TRA2B and SRSF3 in HEK293 cell line

Project description:We have independently knocked down TRA2B and SRSF3 in HEK293 cells to identify the sum of alternative splicing changes that results from depletion of each factor. Each was compared to a control transfection of the hairpin vector alone. In this set, 9 total samples were analyzed. There were three biological replicates for each of three conditions: knockdown control, TRA2B knockdown and SRSF3 knockdown. Arrays were analyzed for gene expression using GeneBase and for alternative splicing using MADS+ and OmniViewer software.
