Figure 1.

Nucleotide sequence presentation of the tetracycline-inducible U6 and H1 promoter variants and anti-luc shRNA used in this study. PSE (proximal sequence element) is shown in italic letters. The TATA box is shaded in gray. O1 and O2 indicate O1-type and O2-type tetracycline operator (tetO) sequences, respectively. TetO sequences are shown in bold letters. The anti-luciferase shRNA sequence is underlined.
