Sample GSM4874827 Query DataSets for GSM4874827
Status Public on Oct 31, 2020
Title APP/PS1xRIPK1KD rep1
Sample type SRA
 
Source name Brain
Organism Mus musculus
Characteristics strain: C57BL/6
genotype/variation: APP/PS1xRIPK1KD
Sex: Male
age: 6 months
tissue: Brain
cell type: Endothelial cells (CD31+CD45-)
Extracted molecule total RNA
Extraction protocol Brain endothelial cells were isolated by FACS (CD31+CD45-) from brain homogenates.
20000 cells were collected and RNA was extracted from isolated cerebral ECs using Quick-RNA MiniPrep kit (Zymo Research) with the in-column DNase treatment. Each library was prepared using the Smart-seq2 protocol with a tagged oligo (dT) primer to make first strand cDNA from 1.5ng total RNA input.
Double-stranded cDNA was generated for library construction with 12 cycles of PCR and 0.075 ng of cDNA was used as input in a ΒΌ volume of standard NexteraXT (Illumina) reaction. Libraries were sequenced on an Illumina NextSeq500 instrument with 50 bases for read1 and 25 bases read2.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Description 6-month-old male APP/PS1-RIPK1-KD mouse was sacrificed for isolating endothelial cells. The mRNA of isolated endothelial cells was extracted for next-generation sequencing.

Data processing Illumina Casava1.7 software used for basecalling.
Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to mm10 whole genome using bowtie v0.12.2 with parameters -q -p 4 -e 100 -y -a -m 10 --best --strata
Reads Per Kilobase of exon per Megabase of library size (RPKM) were calculated and normalized by the size of the meta-transcript and by the size of the library.
Genome_build: mm10 (GRCm38)
Supplementary_files_format_and_content: nextseq_170608_rsem.genes.counts.matrix: Tab-delimited text file includes RPKM values for all samples.
