Figure 2. DEX exposure alters mRNA expression levels of DNMTs and TETs. The transcription level of DNA methylation-related enzymes, DNA methyltransferases (DNMTs) (A–C), and ten-eleven translocations (TETs) (D–F) was determined with quantitative real-time PCR (qRT-PCR) after 48 h of dexamethasone (DEX) exposure. Data from three independent experiments (mean ± standard deviation [SD]).*p<0.05, **p<0.01, ***p<0.001 with the Student two-tailed t test.
