Figure 3From: NF-κB signaling and vesicle transport are correlated with the reactivation of the memory trace of morphine dependenceThe DNA methylation level upstream of TSSs is closely related to gene expression. Correlation between methylation changes of CpGs and mRNA level changes of associated genes between morphine group and control (P values, Pearson's correlation test). Each dot stood for a CpG site with a cutoff of 25% methylation change.Back to article page
