Title |
B cell Nfil3-KO rep1 |
Sample type |
SRA |
|
|
Source name |
spleen B cell
|
Organism |
Mus musculus |
Characteristics |
strain: C57BL/6 tissue: spleen cell type: B cell genotype: Nfil3-/- treatment: IL-4 (20ng/mL) + LPS (5ug/mL) for 24 hours
|
Treatment protocol |
B cells were stimulated with IL-4 (20 ng/mL) and LPS (5 mg/mL) for 24 hours.
|
Growth protocol |
CD317- B220- MHC II+ CD11c+ XCR1+ CD172a- cDC1s were sorted from CD11c enriched splenocytes. CD19+ B220+ B cells were sorted from splenocytes.
|
Extracted molecule |
total RNA |
Extraction protocol |
RNA was isolated from 200,000 live B cells sorted after stimulation or 120,000 cDC1 using NucleoSpin RNA XS Kit (Macherey-Nagel). Total RNA integrity was determined using Agilent Bioanalyzer or 4200 Tapestation. Library preparation was performed with 10ng of total RNA with a Bioanalyzer RIN score greater than 8.0. ds-cDNA was prepared using the SMARTer Ultra Low RNA kit for Illumina Sequencing (Takara-Clontech) per manufacturer's protocol. cDNA was fragmented using a Covaris E220 sonicator using peak incident power 18, duty factor 20%, cycles per burst 50 for 120 seconds. cDNA was blunt ended, had an A base added to the 3' ends, and then had Illumina sequencing adapters ligated to the ends. Ligated fragments were then amplified for 12-15 cycles using primers incorporating unique dual index tags. Fragments were sequenced on an Illumina NovaSeq-6000 using paired end reads extending 150 bases.

Data processing |
Basecalls and demultiplexing were performed with Illumina’s bcl2fastq software and a custom python demultiplexing program with a maximum of one mismatch in the indexing read. RNA-seq reads were then aligned to the Ensembl release 76 primary assembly with STAR version 2.5.1a. Gene counts were derived from the number of uniquely aligned unambiguous reads by Subread:featureCount version 1.4.6-p5. Isoform expression of known Ensembl transcripts were estimated with Salmon version 0.8.2. All gene counts were then imported into the R/Bioconductor package EdgeR and TMM normalization size factors were calculated to adjust for samples for differences in library size. Ribosomal genes and genes not expressed in the smallest group size minus one samples greater than one count-per-million were excluded from further analysis. The TMM size factors and the matrix of counts were then imported into the R/Bioconductor package Limma. Weighted likelihoods based on the observed mean-variance relationship of every gene and sample were then calculated for all samples with the voomWithQualityWeights. The performance of all genes was assessed with plots of the residual standard deviation of every gene to their average log-count with a robustly fitted trend line of the residuals. Differential expression analysis was then performed to analyze for differences between conditions and the results were filtered for only those genes with Benjamini-Hochberg false-discovery rate adjusted p-values less than or equal to 0.05.
