title: 5-bromodeoxyuridine increases transient expression of ectopic genes in human cells.
abstract: Ectopic genes transferred to cells are temporally expressed, although this phenomenon has not yet been well characterized. We found that 5-bromodeoxyuridine dramatically increased transient expression of ectopic genes in human cells. This effect was elicited by adding 5-bromodeoxyuridine prior to or after transfection. No promoter specificity was observed. Real time PCR analysis showed an approximately 2-fold increase in mRNA levels. Since 5-bromodeoxyuridine decondenses heterochromatin and changes the nuclear envelope, these changes might affect transcriptional and post-transcriptional events in the gene expression of plasmids.
