Effects of arsenic trioxide on the methylation of TMS1 gene in K562 cells

摘要

Objective To detect the methylation status of TMS1gene and its demethylation by arsenic trioxide(As2O2)in K562 cells.Methods K562 cells were treated with different concentrations of As2O2for 48 hours.Methylationspecific PCR(MSP)was used to determine the methylation status of TMS1.RT-PCR and Western blot were used to detect the levels of TMS1 mRNA and protein.
