pSBtet-6 autoregulatory system showed superior regulation to pSBtet with (A) luciferase fold induction, but (B) higher background expression at the mRNA level for Mcl-1. (C) Comparison of maximal expression of luciferase in pSBtet-6 versus constitutive expression of G72V (psBtet-5) after induction with doxycycline. pSBtet-6 showed higher sensitivity, but higher background expression in the absence of doxycycline compared to pSBtet-5. Experiments were carried out 96 h post-transfection. Statistical analysis: one-way ANOVA test with Bonferroni post-test correction (*P < 0.05, **P < 0.01, ***P < 0.001).
