Sample GSM6578427 Query DataSets for GSM6578427
Status Public on Jan 31, 2024
Title nub>mRFP; ecd-RNAi rep 1
Sample type SRA
 
Source name Wing disc, L3
Organism Drosophila melanogaster
Characteristics tissue: Wing disc, L3
genotype: nub>mRFP; ecd-RNAi
treatment: ecd RNAi
Treatment protocol RNAi against ecd was driven in the nubbin domain of D. melanogaster larvae continuously until sample collection
Growth protocol Dosophila crosses were kept on a diet consisting of 0.8% agar, 8% cornmeal, 1% soymeal, 1.8% dry yeast, 8% malt extract and 2.2% sugar-beet syrup, supplemented with 0.625% propionic acid and 0.15% Nipagin, and maintained at 25 °C. Wing discs were collected from third-instar larvae 7 days after egg-laying
Extracted molecule total RNA
Extraction protocol For RNA isolation, 150 WDs were dissected from third instar larvae in 1xPBS and snap-frozen in liquid nitrogen, and processed according to standard TRI Reagent protocol (Sigma Aldrich, #T9424) with DNase I treatment (Invitrogen, #AM2238).
For RNA sequencing, 2 μg of total RNA was used for library preparation (Illumina TruSeq Stranded total RNA Ribo-Zero). Pair-end sequencing (four biological replicates of each experimental group) at a read length of 100 bp was performed on an Illumina HiSeq 2000 machine.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Description nrE3
Data processing Initial quality control of the raw data was performed using FastQC (RRID:SCR_014583).
Illumina sequencing adapters were removed from the sequencing reads with the cutadapt tool version 3.5 (Martin, 2011; RRID:SCR_011841)
For differential gene expression analysis, kallisto v0.46.1 (Bray et al., 2016; RRID:SCR_016582) was used for pseudoalignment of obtained reads to the complete Drosophila melanogaster transcriptome (BDGP6.28, Ensembl release 102) and transcript-level abundance quantification using 100 bootstrap samples.
Summarization of the obtained estimated counts to gene-level was performed using tximport v1.22.0 (Bray et al., 2015; RRID:SCR_016752).
Differential gene expression was determined using DESeq2 v1.34.0 (Love et al., 2014; RRID:SCR_015687).
Intron retention was analyzed using NxtIRFcore v1.2.1 (Wang and Ritchie 2022) and IRFinder v2.0.1 (Middleton et al., 2017)
Assembly: BDGP6.28, Ensembl release 104
