Cmv methylation
WebJan 1, 2009 · CMV promoter is methylation sensitive and in vitro methylation leads to its inactivation in transfected cells (Prosch et al., 1996). Extensive CpG and non-CpG methylation of CMV promoter has been associated with its silencing in vivo (Brooks et al., 2004). DNA methylation is known to inhibit the binding of transcription activators like … WebNow methylation of CMV promoter is proposed to be one possible cause for the result.
