Genome-wide DNA methylation maps of Decitabine and/or Cisplatin treated bladder cancer cells.

ABSTRACT: It is well established that low-dose Decitabine treatment can sustain long-term antitumor effects by targeting DNA methylation and altering gene expression32. We performed methylated DNA immunoprecipitation (MEDIP) followed by next-generation sequencing in 5637 cells. Daily Decitabine treatment with 100 nM for 72 hr (with or without 100ng/ml cisplatin treatment) reduced the methylation level at CpG-islands in the genome of 5637 cells . However, this low-dose DEC treatment did not cause a significant reduction of DNA methylation in non-CpG islands regions.Our study represents the first detailed analysis of DNA methylome generated by RNA-seq technology in bladder cancer cells treated with low-dose decitabine. This study help to reveal the direct target genes of decitabine in bladder cancer treatement.
