Figure 5From: Characterization of the human DYRK1A promoter and its regulation by the transcription factor E2F1Upregulation of DYRK1A mRNA by E2F1 overexpression. A) Phoenix cells were transfected with an expression plasmid for E2F1 (2 μg/10 cm plate) or vector DNA (Ctrl). Total RNA was isolated 2 days after transfection and subjected to Northern blot analysis with probes for DYRK1A and GAPDH as indicated. Ethidium bromide-stained bands of the ribosomal RNAs are shown as a loading control. B) Saos2 cells expressing E2F1 under the control of a doxycycline-inducible promoter were treated for 18 h with doxycycline (E2F1), or were not treated (Ctrl) before the RNA was isolated. Duplicate lanes contain RNA from parallel plates.Back to article page
