Sample GSM7048279 Query DataSets for GSM7048279
Status Public on Jan 05, 2024
Title male_T1_female_TM3_piRNA_1
Sample type SRA
 
Source name adult fly ovaries total small RNA
Organism Drosophila melanogaster
Characteristics tissue: adult fly ovaries
chipantibody: none
reporter: T1 BX reporter
molecule subtype: total small RNA
Treatment protocol Flies were fed with yeast for 2-3 days prior to dissection
Growth protocol Fly stocks were maintained at 24C on standard diet
Extracted molecule total RNA
Extraction protocol Total smRNA from ovary was isolated with Ribozol reagent and do size selection from 19nt to 30nt. Total smRNA from ovary was isolated with Ribozol reagent and do ribosomal RNA depeltion.
smRNA-seq libraries were made by using NEBNext® Small RNA Library Prep Set for Illumina®. Degradome-seq libraries were prepared by using protocol from Zamore lab. Libraries were sequenced on the Illumina HiSeq 2000 platform.
smRNA-seq follow NEBNext® Small RNA Library Prep Set for Illumina®
 
Library strategy ncRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina HiSeq 2000
 
Data processing Degradome-seq reads were trimmed by Trimmomatic (version 0.33) and cutadapt (version 1.15) and filter out those shorter than 50 bp after trimming
Ribosomal RNA removal by bowtie
The first 50bp of reads were mapped to dm6 genome and vectors sequence respectively, using STAR alignment
smRNA-seq reads were trimmed by Cutadapt to rRNA and filter out those shorter than 15 bp after trimming
Select reads size 21-22bp (siRNA) and 23-29bp (piRNA) and 21-30bp (small RNA)
mapped to dm6 genome and extracted regions 20A cluster(20A) and 42AB cluster(42A), mapped to vector maps, Ubi-GFP(UBIG), non-RMCE Ubi-GFP(originalUBIG), double-stranded GFP reporter(UBIGasG) (parameters: -v 0 -a -m 1 -t --best --strata), and plus, minus strand of genome regions and vectors were separate.
smRNA profilings were generated by Matlab after mapping
Assembly: dm3(ChIP-seq) and dm6(smRNA-seq)
