| Extraction protocol |
total RNA was extracted using a RNeasy MinElute Cleanup Kit
NEBNext DNA Library Prep Master Mix Set for Illumina for RNA-seq and NEXTflex ChIP-seq Kit, Bioo Scientific for chip-seq
RNA-seq: total RNA was extracted using a RNeasy MinElute Cleanup Kit (QIAGEN, Catalog no. 74204). Double-stranded cDNA was synthesized according to the mRNA Sequencing Sample Preparation Guide (part#1004898 Rev.D, Illumina, San Diego, CA) and single-end libraries were prepared using the NEBNext DNA Library Prep Master Mix Set for Illumina (New England BioLabs, Catalog no.74204 E6040L). For RNA-seq of RNaseH treated MEF cells, the protocols were mainly adopted as previously described (Nat Methods 10: 623-629). For qRNA-seq of MEF cells, the GeneRead rRNA Depletion Kit (Qiagen) was used to remove ribosome RNA. Nascent RNA-seq of U2OS cells was performed as previously described (Science 322: 1845-1848), with the exception of not applying a strand specific method.
ChIP-seq procedure as previously described (Cell. 2013 May 9;153(4):855-68). For the Bmal1 and IgG ChIP-seq, the RIPA buffer was diluted 1 to 10. For HIF1A CHIP-seq, protocols are used as described (ChIP-IT high sensitive kit (Cat# 53040, Active Motif)). The library was constructed using a commercially available kit (NEXTflex ChIP-seq Kit, Bioo Scientific). Samples were indexed using NEXTflex™ DNA Barcodes (Bioo Scientific). The library was qualified using an Agilent 2100 Bioanalyzer (Agilent) and quantified using KAPA Library Quantification Kits (Kappa Biosystems). Finally, the indexed libraries were sequenced using a HiSeq 2500 (Illumina).
