Analysis of targets that could mediate these phenotypic changes indicated that c-Maf likely plays a key role in myeloid cell development through dual mechanisms; inhibition of a select set of c-Myb regulated targets, such as Bcl-2 and CD13/APN , coupled with the activation of as yet undefined differentiation-promoting genes .
