Fig 5. mRNA expression of bBoule in BMECs treated with 5-Aza-dC.

mRNA expression was detected in treated cells but not in untreated cells by qRT-PCR. All experiments were performed three times. The bar above the histogram indicates the SEM. Different uppercase letters denote significant differences between different groups with a significance level of P < 0.01. Different lowercase letters denote significant differences between different groups with a significance level of P < 0.05.
