[Effect of eukaryotic expression plasmid DNA methyltransferase gene on methylation status and transcription level of DNA mismatch repair genes in human colon cancer cell line].

Abstract excerpt

OBJECTIVE: To analyze the effect of eukaryotic plasmids containing sense or antisense DNA methyltransferase (Dnmt1) genes on the methylation status and transcription level of DNA mismatch repair (MMR) genes and microsatellite instability (MSI) in human colon cancer cell line. METHODS: Human colorectal cells of the SW1116 line were cultured. Recombinant plasmids containing sense Dnmt1 (HMT) or antisense Dnmt1...
