Sample GSM4908754 Query DataSets for GSM4908754
Status Public on Nov 16, 2020
Title 4hrs_T4
Sample type SRA
 
Source name Retina
Organism Gallus gallus
Characteristics tissue: Retina
breed: White Leghorn
Sex: Male
treatment: FDM + TPMPA injection, replicate 4
age: Post-hatch day 7
timepoint: 4 hours
Treatment protocol Male chicks were raised for 6 days under a 12 hours day/night light cycle. On day 7, chicks were randomly assigned to seven groups (age-matched untreated, FDM, FDM + atropine, FDM + pirenzepine, FDM + ADTN, FDM + TPMPA or recovery from FDM). Following 4 or 24 hours after diffuser attachment and/or intravitreal injection, retinae were collected, total RNA extracted and libraries prepared. For the 24-hour timepoint, a repeat injection was given 4 hours prior to collection. For recovery from FDM, chicks wore translucent diffusers for a period of 3 days to induce myopia before removing the device and collecting the retina 4 or 24 hours later.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated from the retina using the Trizol/chloroform protocol. RNA quality and quantity was assessed on a 2100 Bioanalyser. All samples had an RNA Integrity Number (RIN) greater than 7.0.
Libraries were prepared using the Ultra Directional RNA Library Kit for Illumina following the manufacturer's instructions. Libraries were validated on a 2100 Bioanalyser. Libraries were normalised to 4 ng/µL in 0.1x TE, pooled and sequenced at the Ramaciotti Centre for Genomics (UNSW, Sydney, Australia) on an Illumina NextSeq 500 platform (paired-end, 75 cycles).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Data processing Reads were adaptor stripped using Trimmomatic software (v0.36).
Reads were mapped to the chick genome (GalGal5) using HISAT2 (v2.1).
Counts for ENSEMBL transcripts were obtained using analyzeRNA.pl, script from HOMER package.
Differential gene expression was analysed using EdgeR/limma with sample batch as blocking factor (Bioconductor release 3.6).
Genome_build: GalGal5
Supplementary_files_format_and_content: The CSV file was generated using the data processing steps described above. The table contains raw counts per sample, per condition, per timepoint.
