Next Generation Sequencing Facilitates Quantitative Analysis of Manganese (II) or LPS treated Wild Type BMDC Transcriptomes

Purpose: The goals of this study are to compare the different functions of manganese (II) and LPS on the activation and maturation of antigen presenting cells-BMDCs. Methods: BMDCs were generated by culturing bone marrow cells with 20 ng/ml of IL-4 (Genscript) and 20 ng/ml of GM-CSF (Genscript) at 37°C and 5% CO2 for 7 days.Then BMDCs were treated with MnCl2 (200 μM) or LPS (100 ng/ml) for 20 h. Then mRNAs were purified, sequenced and analyzed. Results: Using an optimized data analysis workflow, we compared 20339 transcripts in BMDCs. Manganese (II) induced 1677 transcripts expression with a fold change ≥1.5 and LPS induced 1555 transcripts expression with a fold change ≥1.5. Conclusion: Manganese (II) activates the production of type I IFNs and the maturation of BMDCs. But there are also some differences between functions of manganese (II) and LPS on BMDCs. mRNA profiles of control, Manganese (II) or LPS treated BMDCs were generated by deep sequencing, in triplicate, using Illumina Hiseq2500.
