Sample GSM3514568 Query DataSets for GSM3514568
Status Public on Jul 15, 2019
Title P1+1.5Sham_rep1
Sample type SRA
 
Source name Mouse ventricle approximate to below left anterior descending artery ligation plane in age-matched MI samples
Organism Mus musculus
Characteristics strain: ICR/CD1
surgery performed at developmental age: Postnatal day 1
sample collected at post-surgical day: day 1.5
surgery type: Sham
Extracted molecule total RNA
Extraction protocol Each heart was dissected in ice-cold PBS and a transverse cut on ligation plane was made, separating it into above ligation plane (ALP) part and below ligation plane (BLP) part. BLP parts were flash-frozen with liquid nitrogen and stored in -80°C for RNA-Seq. The collected tissue samples were ground to powder in liquid nitrogen, resuspended in 1 mL Trizol per 50 mg of tissue, and homogenized using 20G1/2 needles. After chloroform extraction, the aqueous phase was mixed with an equal volume of 75% ethanol and further purified using RNeasy Mini Kit (QIAGEN, 74104) according to manufacturer’s protocol.
Stranded mRNA-Seq libraries were generated using KAPA mRNA HyperPrep Kit (Roche, KK8581) following manufacturer’s protocol.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Data processing Quality control of RNA-Seq data was performed using FastQC Tool (Version 0.11.4).
Sequencing reads were aligned to mouse GRCm38 (mm10) reference genome using HiSTAT2 (Version 2.0.4) with default settings and --rna-strandness F.
Aligned reads were counted using featurecount (Version 1.6.0) per gene ID.
Differential gene expression analysis was performed with the R package edgeR (Version 3.20.5) using the GLM approach. For each comparison, genes with more than 1 CPM (Count Per Million) in at least three samples were considered as expressed and were used for calculating normalization factor. Cutoff values of absolute fold change greater than 2.0 and false discovery rate less than 0.01 were used to select differentially expressed genes between sample group comparisons. Normalized gene CPM values were used to calculate RPKM (Reads Per Kilobase per Million mapped reads) values, which were then used for heatmap plotting.
