Next Generation Sequencing Facilitates Quantitative Analysis of wild type and Rbm25-deficient Bone Marrow Derived macrophage Transcriptomes

Purpose: The purpose of this study is to detect activated or silenced genes during wild type (WT) and Rbm25-deficient bone marrow derived macrophages (BMDMs). Gene expression differences between two samples could be found using transcriptome profiling (RNA-seq) analysis. Methods: Mouse BMDMs were generated from bone marrow cells in RPMI-1640 medium with recombinant mouse M-CSF (20ng/ml). BMDMs were stained to confirm the surface expression of CD11b and F4/80. Cells with purity >97.5% were used for subsequent experiments. WT and Rbm25 deficient BMDMs were stimulated with LPS (100ng/ml) for 0, 2 or 8 hours, of which RNA profiles were generated by deep sequencing, using Illumina. Results: We mapped about 10 million sequence reads per sample to the mouse genome, identified hundreds of genes with significant mRNA variation between WT and Rbm25 deficient BMDMs. mRNA profiles of WT and Rbm25 deficient BMDMs were generated by deep sequencing.
