Abstract Dysregulation of master regulator c-MYC (MYC) plays a central role in hepatocellular carcinoma (HCC) and other cancers but remains an elusive target for therapeutic intervention. MYC expression is epigenetically modulated within naturally occurring DNA loop structures, Insulated Genomic Domains (IGDs). We present a therapeutic approach using an epigenomic controller (EC), a programmable epigenomic mRNA medicine, to precisely modify MYC IGD sub-elements, leading to methylation of MYC regulatory elements and durable downregulation of MYC mRNA transcription. Significant antitumor activity is observed in preclinical models of HCC treated with the MYC-targeted EC, as monotherapy or in combination with tyrosine kinase or immune checkpoint inhibitors. These findings pave the way for clinical development of MYC-targeting epigenomic controllers in HCC patients and provide a framework for programmable epigenomic mRNA therapeutics for cancer and other diseases. |
