Fig. 6. Pax1 and Pax9 transactivation activity on different Bapx1 promoter deletion constructs. (A) Bapx1 promoter deletion plasmids used in transient transfection assays. (B) Luciferase activity driven by the Bapx1 promoter deletion constructs or control vector (pGL3-Basic), alone or co-transfected with the indicated amounts of expression plasmids for Pax1 (pPax1) or Pax9 (pPax9), or both. Numbers inside or above the bars indicate the time fold induction with respect to the basal activity of the same construct in the absence of transfected Pax1 and Pax9. Lines in the bars indicate s.d.
