Title |
Non-microglia cells from Trem2 +/- animal 7674 after 12 weeks on control diet |
Sample type |
SRA |
|
|
Source name |
Non-microglia isolated from whole brain
|
Organism |
Mus musculus |
Characteristics |
genotype: Trem2 +/- tissue: brain cell_type: other animal_id: 7674 diet: control Sex: female timepoint: 12 timepoint_unit: weeks
|
Treatment protocol |
Trem2-WT, heterozyogus knockout, and homozygous knockout mice were fed a control or 0.2% cuprizone diet for 5 weeks or 12 weeks.
|
Growth protocol |
Mice were housed on a 12hr/12hr light dark cycle. All mouse husbandry and experimental procedures were approved by Denali's Institutional Animal Care and Use Committee.
|
Extracted molecule |
total RNA |
Extraction protocol |
Mice were perfused with PBS, brain were removed and dissociated with the Adult Brain Dissociation Kit (Miltenyi). Cells were fluorescence-activated cell sorted for viability, then microglia (Cd11b+) and all other cells were collected for RNA extaction using the RNeasy Plus Micro kit (Qiagen) Libraries were prepared using the QuantSeq 3’ mRNA-Seq Library Prep Kit FWD for Illumina (Lexogen), following the ‘low-input’ procedure defined by the manufacturer.

Data processing |
Sequencing adapters were trimmed using skewer (Jiang et al., 2014; version 0.2.2) with default parameters. Quality control of the trimmed reads was performed using FastQC (version 0.11.5: www.bioinformatics.babraham.ac.uk/projects/fastqc). Reads were aligned to an index of the mouse genome (version GRCm38_p6) A STAR index (Dobin et al., 2013; version 2.5.3a) was built with the --sjdbOverhang=50 argument. Splice junctions from Gencode gene models (release M17) were provided via the --sjdbGTFfile argument. STAR alignments were generated with the following parameters: --outFilterType BySJout --quantMode TranscriptomeSAM --outFilterIntronMotifs RemoveNoncanonicalUnannotated --outSAMstrandField intronMotif --outSAMattributes NH HI AS nM MD XS --outSAMunmapped Within. Post-alignment quality control reports were generated using MultiQC (Ewels et al., 2016; version 1.0). The raw gene expression matrix was constructed from the 'forward' column of STAR's ReadsPerGene.out.tab output files using R (version 3.4.3). Gene symbols and Entrez gene identifiers were mapped using Ensembl (version 91) via the biomaRt R package (Durinck et al, 2009; version 2.34.0). Genome_build: GRCm38 Supplementary_files_format_and_content: tab-delimited, gzip-compressed text file with matrix of raw quantitation results for each sample.
