Myc-mediated SDHA Acetylation Triggers Epigenetic Regulation of Gene Expression and Tumorigenesis.

ABSTRACT: 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.
