Targeted methylation of cg24067911 suppresses colorectal cancer metastasis through BCL6-ATXN1-CDH1 axis.

ABSTRACT: DNA methylation plays a crucial role in the progression and metastasis of colorectal cancer (CRC), yet the mechanisms underlying its effect at specific loci remain poorly understood. We previously identified cg24067911 hypomethylation as a potential biomarker associated with poor CRC prognosis. To investigate the role of cg24067911 methylation in CRC metastasis and elucidate its underlying molecular mechanisms, we utilized the CRISPR-dCas9-DNMT3a system to specifically modify the methylation status of cg24067911. Then, we performed high-throughput transposase-accessible chromatin sequencing, RNA sequencing, and chromatin immunoprecipitation analysis. We demonstrated that cg24067911 was located within an enhancer region of the ATXN1 gene, where it was bound by BCL6. Hypomethylation of cg240
