| Summary |
Trimethylated H3K4 (H3K4me3), which is often found surrounding the transcriptional start site of active genes, is strongly enriched in the promoter regions of Myc-targeted genes. Succinate, which inhibits JmjC domain-containing histone demethylases (JHDMs), can induce H3K4me3 level of the promoter regions. It's interesting to ask whether Myc can mediate H3K4me3 by regulating cellular succinate level. Here, We used ChIP-seq to study Myc modulates H3K4me3 by altering succinate levels, dimethyl succinate (DMS), a membrane-permeable succinate analog, was introduced to treat CA46 cells with high or depleted Myc expression. And we also performed RNA-seq assays in Myc expressed or depleted CA46 cells with or without DMS treatment.

| Overall design |
CA46 cells were infected with viruses expressing non-targeting control (NTC) or Myc shRNA for 48h in presence of methyl succinate (DMS) and followed by H3K4me3 ChIP-seq to address whether succinate can induce H3K4me3 level of the promoter regions in CA46 cells with depleted Myc expression. For the CA46 cells’ ChIP-seq experiments with spike-in control, Drosophila chromatin (Active Motif 53083) and a Drosophila-specific antibody (Active Motif 61686) were used for each reaction. The D. melanogaster-specific antibody is used to immunoprecipitate D. melanogaster chromatin from each reaction, which is then used as a reference for normalization during data analysis. And ChIP-seq was sequenced at Novogene (Tianjin, China) on the Illumina novaseq6000 platform. Meanwhile, we also performed RNA extraction from these cell samples and sequenced on Illumina novaseq6000 platform.
