Abstract excerpt
We previously demonstrated that IL-3 stimulates transcription of the antiapoptotic gene mcl-1 via two promoter elements designated as the SIE and CRE-2 sites. To further study the functional role of these two DNA elements, mutant mice with targeted mutations of both SIE and CRE-2 sites (SC mutants) were generated. Homozygous SC mutants manifested a markedly reduced level of Mcl-1 in thymus but not in other major...
