Next Generation Sequencing analysis of Hes1+/+ Cre-ERT2 and Hes1fl/fl Cre-ERT2 bone marrow derived macrophages transcriptomes.. Next Generation Sequencing analysis of Hes1+/+ Cre-ERT2 and Hes1fl/fl Cre-ERT2 bone marrow derived macrophages transcriptomes.

To evaluate the potential role of Hes1 in regulation of type I IFNs and the downstream ISGs expression, we generated the bone marrow-derived macrophages (BMDMs) from Hes1+/+ Cre-ERT2 and Hes1fl/fl Cre-ERT2 mice. RNA-sequencing analysis of Poly(I:C) [(polyinosinic: polycytidylic acid), a mimic of viral double-stranded RNA]-treated BMDMs revealed that 49 genes were induced more than two-fold by Poly(I:C) for 3 hrs in Hes1-deficient BMDMs relative to their expression in Hes1+/+Cre-ERT2 cells. Notably, 67.3% of these upregulated genes were ISGs by screening the Interferome database, suggesting that Hes1 inhibits expression of TLR-mediated ISGs,these results indicated that Hes1 negatively regulates TLR3-mediated induction of ISGs in macrophages. Overall design: mRNA profiles of BMDMs from Hes1+/+ Cre-ERT2 and Hes1fl/fl Cre-ERT2 mice with or without Poly(I:C) treatment for 1 or 3 hours.
