shRNA Sensor Analysis of DSIR Selected shRNAs

Project description:Purpose: Generate a large, high quality database of paired shRNA efficacy/sequence datapoints. Methods:Twelve shRNAs for each Refseq annotated human gene were selected based on the DSIR algorithm. Twelve batches of ~22K shRNAs (corresponding to 12 agilent chips) were then assessed for efficacy via the sensor method outlined in Fellmann et al, Mol Cell, 2011. Conclusions: Neighboring nucleotide combinations are best at predicting shRNA efficacy.

shRNA Sensor Analysis of 5' U converted shRNAs reveals 3' target bias exists in addition to 5' guide bias

Project description:shRNAs selected with the shERWOOD algorithm were converted to have a U at the 5' end of their guide. When endogenous 1U shRNAs were compared to artificial shRNA via the sensor algorithm, the endogenous shRNAs were found to be more efficacious. Purpose: Structural studies have hinted that the 5' end of shRNA guides is engulfed in the RISC complex. It has also been reported that shRNAs with a 5' U are more efficacious than those with other 5' caps. We wished to determine whether replacement of shRNA guide 5' nucleotides with a U, regardless of the corresponding target base, would increase their efficacy. Method: For each gene in the "druggable genome" 10 shRNAs were selected with the shERWOOD algorithm. In each case the score was assessed as if the guide had a 5' U. Sensor constructs were designed pairing 1U-guide shRNAs with their endogenous target. shRNAs were assessed for efficacy via the shRNA sensor assay (Fellmann et al. Mol Cell 2011). Results: shRNAs with artificial 5' Us were found to be less efficacious than those with an endogenous 5' U,

shRNA knockdown of ZMIZ1 in human T-cell Acute Lymphoblastic Leukemia cell line CEM

Project description:Human T-cell Acute lymphoblastic Leukemia cell line CEM was transfected with either shRNA against ZMIZ1 or scrambled shRNA. Four (non-paired) biological replicates of each condition had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets. A supplementary Excel workbook holding the same processed data as the series matrix file is provided, with some probe set annotation, and a simple statistical comparison. The raw (.CEL) files are also provided. Keywords: Expression profiling by array Human T-cell Acute lymphoblastic Leukemia cell line CEM was transfected with either shRNA against ZMIZ1 or scrambled shRNA. Four (non-paired) biological replicates of each condition had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets.

The effect of ERG overexpression and ERG knockdown by shRNA in RWPE1 and VCAP cells, respectively

Project description:The goal of this project was to analyze the global gene expression profiles of RWPE1 and VCAP cells following transfection of GFP, GFP-ERG at 48 and 72hrs time points and stable ERG shRNA, scramble shRNA, respectively. RWPE1 cells were transfected with GFP or GFP-ERG. VCAP cells were transfected with ERG lenti-shRNA or scramble shRNA. Transfections were performed in duplicate. Total cellular RNA was isolated with Trizol and quality analysed by the bioanalyser kit.
