Sample GSM4767068 Query DataSets for GSM4767068
Status Public on Sep 05, 2020
Title Rat 16 Brain microRNA seq
Sample type SRA
 
Source name Brain
Organism Rattus norvegicus
Characteristics animal number: 16
treatment: Whole Egg
strain: Lean
Treatment protocol Animals were fed their respective diets, either Whole Egg or Casein.
Extracted molecule total RNA
Extraction protocol Tissue samples were homogenized on ice and total RNA was extracted using a Lexogen SPLIT RNA Extraction kit following the manufacturers instructions.
Libraries were prepared according to Lexogens instructions accompanying the QuantSeq 3’ mRNA-Seq Library Prep Kit FWD for Illumina and small RNA sequencing kits. Briefly, the Quantseq kit uses total RNA as input, hence no prior poly(A) enrichment or rRNA depletion is needed. Library generation starts with oligodT priming containing the Illumina-specific Read 2 linker sequence. After first strand synthesis the RNA is removed. Second strand synthesis is initiated by random priming and a DNA polymerase. The random primer contains the Illumina-specific Read 1 linker sequence. At this step Unique Molecular Identifiers (UMIs) can be introduced by exchanging the Second Strand Synthesis Mix 1 (SS1) from the standard QuantSeq FWD Kit with UMI Second Strand Synthesis Mix (USS). No purification is required between first and second strand synthesis. Second strand synthesis is followed by a magnetic bead-based purification step rendering the protocol compatible with automation. During the library amplification step sequences required for cluster generation are introduced. NGS reads are generated towards the poly(A) tail and directly correspond to the mRNA sequence. To pinpoint the exact 3’ end, Libraries were sequenced on the Illumina HiSeq 3000 following the manufacturer's protocols.

Data processing Basecalls performed by the ISU DNA facility and data processing steps were followed according to the manufacturers guidelines here: https://www.lexogen.com/wp-content/uploads/2015/11/015UG009V0211_QuantSeq-Illumina.pdf
Briefly, fastq quality control tool FastQC was used to examine the quality of the sequencing run.
Next, adapters were trimmed using BBDUK and sequences were reanalyzed using FastQC
Reads were mapped to the RNO_6 genome using RNA STAR and read counts were simultaneously quantified using the --read-counts flag
