Sample GSM1908867 Query DataSets for GSM1908867
Status Public on Dec 17, 2015
Title unc_X1_d12_4
Sample type SRA
 
Source name X1 cells
Organism Schmidtea mediterranea
Characteristics cell type: X1
replicate: 4
RNAi treatment: unc22
days exposed to rnai: 12
Treatment protocol dsRNA-containing food for RNAi treatment was generated as previously described (Gurley et al., 2008); briefly, cloned genes were transformed into bacterial strain Ht115, induced to express dsRNA with 1mM (final) IPTG, incubated with shaking at 37C for 2 hours, then pelleted, rinsed, and mixed with calf liver paste for ingestion. set1 was treated with RNAi for 6 and 9 days. and mll1/2 was treated with RNAi for 9 and 12 days
Extracted molecule polyA RNA
Extraction protocol To isolate stem cells, we used a well-established method to isolate planarian stem cells by Hoechst blue staining and flow cytometry. Sorted cells were homogenized in Trizol reagent and RNA was isolated per the manufacturer-supplied protocol. Isolated RNA from whole worm tissue was treated with RNase-free DNase on QIagen RNeasy columns and eluted in nuclease-free water.
500ng-1μg RNA per whole worm sample or 100ng of sorted cell RNA was used for generation of RNAseq libraries using the Illumina TruSeq kit.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Description rpkm_mll_X1.txt
Data processing Base calls were performed using CASAVA-1.8.2
Reads were aligned using bowtie with the following parameters: --best --strata -v 2 -m 5 against transcriptome smed_20140614 defined in GEO submission: GSE72389
Read counts to genes were tallied from the SAM files with a custom script. RPKM values were generated using the rpkm function from the edgeR library from Bioconductor in R.
Genome_build: Schmidtea_mediterranea_3.1
Supplementary_files_format_and_content: rpkm.txt files contain tab-delimited RPKM values for each sample.
