Sample GSM2396895 Query DataSets for GSM2396895
Status Public on Sep 18, 2017
Title poolD_mouse4
Sample type SRA
 
Source name RN2 cells (MLL-AF9/NRASG12D)
Organism synthetic construct
Characteristics shRNA pool: poolD
timepoint: bone marrow day 14
Treatment protocol 1 x 106 fully selected AML cells were injected in the tail vein of sublethally irradiated (4.5 Gy, 24h before injection) B6.SJL (CD45.1) female mice 6-8 weeks of age. For shRNA induction, animals were treated with doxycycline in the food (625 mg kg-1, Harlan Laboratories). Leukemic mice were euthanized 14 days after transplantation, at terminal disease stage, by CO2.
Growth protocol Pools of 50 shRNA vectors were used to produce virus and transduce AML cells at a low multiplicity of infection to minimize double infections. Cells were treated with 500 μg ml-1 G-418 (Roche Applied Science) from two days after infection until fully selected.
Extracted molecule genomic DNA
Extraction protocol Library preparation was performed as previously described (Knott (2014) Mol Cell).
In brief, genomic DNA was extracted from the pre-injection pool and the bone marrow cell suspensions using the QIAamp Blood DNA Maxi Kit (Qiagen). For each sample, shRNA hairpins were extracted from genomic DNA in 96 separate 25-cycle PCR reactions where 2 mg of input DNA was included in each reaction.
Following this initial PCR, Illumina adapters were added via PCR, and samples were processed on the Illumina MiSeq platform.

Description Screen_DESeq_allPools.xls
Data processing Reads were extracted and mapped to the shRNAs of the corresponding pool using bowtie (allowing 0 mismatches). Fasta file for the shRNA also included
To analyze the depletion between the final timepoint and input, DESeq was used with Fit type “local”
Genome_build: NA
Supplementary_files_format_and_content: Screen_DESeq_allPools.xls contains the results of DESeq analysis, mjdelasv_GEO_AMLscreen-shRNAs.fasta contains the shRNAs names and sequence.
