Effects of Graffi-1.4 LTR integration in the YY1 promoter region on gene transcription.

Luciferase assays were performed in HEK 293 cells. One representative experiment of 3 is shown. Error bars represent the SD of the mean values of 3 independent experiments. Negative control: empty pGL3 vector. Reporter gene expression was calculated in arbitrary units, relative to β-galactosidase expression.
