ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of AML1B and AML1/ETO fusion gene on the transcription activity of TSC1 and TSC2 promotor and to explore its role in leukemogenesis.</p><p><b>METHODS</b>The luciferase reporter plasmids of TSCs gene promoter containing a AML1 binding site were constructed, and cotransfected into CV-1 cells with AML1B or AML1/ETO expression plasmids separately. The transactivity of TSCs gene promoter was assayed by luminometer.</p><p><b>RESULTS</b>AML1B exhibited a transactivity to TSC2 gene promoter in a dosage-dependant manner, but showed no significant transactivity to TSC1's. The transactivity to TSC2 gene promoter showed 8.55 fold increase as companed with control group at 75 ng of pCMV5-AML/B. AML1/ETO showed a significant transactivity to TSC1, but no transactivity to TSC2's. However, AML1/ETO antagonized the effect of AMLlB to TSC2 gene promoter.</p><p><b>CONCLUSION</b>AML1B and AML1/ETO can regulate the transcription of TSC genes.</p>
