Next Generation Sequencing Facilitates Quantitative Analysis of Vehicle or R-2-HG Treating Mouse Peritoneal Macrophages Transcriptomes

Purpose: The goals of this study are to screen differentially expressed genes in mouse peritoneal macrophages treated by vehicle or R-2-HG and to explore potential mechanisms of how R-2-HG regulating the process of macrophage activation.  Methods: After RNA extraction, purification, and library construction, the samples were paired-end (PE) sequenced by Next-Generation Sequencing using an Illumina sequencing platform (Illumina HiSeq 2500). After sequencing, the filtered high-quality sequences (Clean Data) filtered from the original raw data were mapped to the Mus_musculus GRCm38.p4 (mm10) genome. Based on the mapped results, the expression level of each gene was calculated, and the samples of the different groups were subjected to further analysis for differences in expression, enrichment, and cluster analysis. Results: The mRNA expression levels of only a few genes were changed after R-2-HG treatment in mouse peritoneal macrophages, but HIF1A was not included. Conclusions:Regulating the macrophage activation by R-2-HG may not be due to its effect on gene transcription, and R-2-HG doses not affect the mRNA expression of HIF1A.
