Sample GSM3831313 Query DataSets for GSM3831313
Status Public on Sep 29, 2020
Title Old HFD 3 RNAseq
Sample type SRA
Source name Islets
Organism Mus musculus
Characteristics age group: Old
diet: high fat diet
strain: C57BL/6
tissue: Islets
age: 1 year
genotype: wild type
Treatment protocol Male mice 8 weeks or 52 weeks old were put on diets of 41% or 13.1 % kcal from fat diet for 1 week
Growth protocol C57/BL6J mice
Extracted molecule total RNA
Extraction protocol Islets were isolated, RNA was harvested using Trizol reagent. Illumina TruSeq RNA Sample Prep Kit (Cat#FC-122-1001) was used with 1 ug of total RNA for the construction of sequencing libraries.
RNA sequencing libraries were prepared using the TruSeqStranded mRNA Library Preparation Kit in accordance with the manufacturer’s instructions (Illumina, Inc., San Diego, CA).
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
Description RNAseq
Data processing >> RNA-Seq <<
Reads were aligned to the mm10 mouse reference using STAR aligner (v2.4.2a)
Quantification of genes annotated in Gencode vM5 was performed using featureCounts (v1.4.3)
Quantification of transcripts used Kalisto
QC were collected with Picard (v1.83) and RSeQC
Normalization of feature counts and differential expression analysis was done using the DESeq2 package
