DNMT1 and neoplasm: As LncCCAT1 shares a miR-148a/152 response element with DNA methyltransferase 1 (DNMT1), a known target of miR-148a/152 15, and participates in tumor progression by methylating and silencing tumor suppressor genes, we investigated whether LncCCAT1 could upregulate DNMT1 through sequestration of miR-148a/152.
