| Extraction protocol |
DNA was extracted by Universal Genomic DNA Kit (CWbiotech, CW2298).
Genomic DNA was digested to 100-500 bp and purified with Agencourt AMPure XP beads (BECKMAN COULTER) following Spin-6 column (Bio-rad) purification. 2 μg DNA fragments and 15 pg spike_in sequences were used for end repair with NEBNext® End Repair Module (NEB, E6050) and 1 μl E.coli ligase was added to repair nicks in DNA. DNA was then purified with 1.8×AMPure XP beads. dA was added to the 3’ end of double-stranded DNA by NEBNext® dA-Tailing Module (NEB, E6053) and purified with 1.8×AMPure XP beads.
Damages that may interfere the following labeling step were repaired. DNA was purified and subjected to in vitro BER labeling. For samples named "biotin-dCTP", biotin-dCTP was utilized in the in vitro BER labeling;other samples utilized biotin-dUTP. After purification, fragments labeled with biotin were enriched by streptavidin C1 beads (Invitrogen) following the manufacturer’s guidelines.
Y adaptor was ligated to double-stranded DNA on streptavidin C1 beads so that free adaptor can be removed by beads washing. DNA was then eluted from beads by 95 °C 3 min using deionized water. Eluted DNA was subjected to PCR amplification and sequencing.

| Data processing |
150bp pairend Raw reads were firstly sent for adaptor and quality trimming using trim_galore, and reads shorter than 25 nt after trimming were excluded. For spike-in DNA sequences calculation, bowtie2 was used to reads mapping to corresponding sequences. For genome-wide dU sites identification, processed reads mapped to spike- in sequence were discarded, and then mapped to human reference genome (hg38) using bowtie2. By default, bowtie2 searches for multiple alignments bowtie2 search and only reports a random one in the best matches; for repeat sequences, bowtie reports the best matched locus or random one from the best-matched loci. After alignment, peaks were called using model-based analysis of ChIP-Seq (MACS2) using nonredundant reads. Peaks overlap with that in the control sample were removed. Genomic annotations were performed using Homer software. Gene annotations(RefSeq) were download from UCSC.
