FIG. 9.

Transactivation of mim-1 reporter genes by different variants of v-Myb. HD11 cells were transfected with 5 μg of the reporter genes shown on the left, pCMVβ (0.2 μg), and 5 μg of expression vectors for E26 v-Myb (top panel) or AMV v-Myb (bottom panel). Controls lacking v-Myb (black columns) were transfected with 5 μg of empty expression vector. Luciferase and β-galactosidase activities were determined 24 h after transfection. Bars show the average luciferase activity normalized with respect to the β-galactosidase activity and expressed in arbitrary units. The luciferase activity in the absence of v-Myb was designated 1 in each case. The T bars show standard deviations. Enh, enhancer.
