Reciprocal regulation of adipogenesis by Myc and C / EBP alpha . 3T3 L 1 adipoblasts that express large amounts of c Myc can not terminally differentiate , raising the possibility that Myc inhibits the expression of genes that promote adipogenesis . ^^^ Expression of Myc prohibited the normal induction of C / EBP alpha and prevented adipogenesis . ^^^ Enforced expression of C / EBP alpha overcame the Myc induced block to differentiation . ^^^ These results provide a molecular basis for the regulation of adipogenesis and implicate Myc and C / EBP alpha as pivotal controlling elements . . ^^^ |

Reciprocal regulation of gadd 45 by C / EBP alpha and c Myc . ^^^ We also found that c Myc antagonized C / EBP alpha mediated transactivation of gadd 45 . ^^^ Analysis of systematically altered forms of C / EBP alpha revealed that c Myc antagonism targeted the antimitotic , transcriptional activation domain of C / EBP alpha . ^^^ In addition , we localized the regulatory sequences in the gadd 45 promoter that are required for c Myc antagonism of C / EBP alpha transactivation . ^^^ In addition , our findings reveal that the reciprocal relation between C / EBP alpha and c Myc in 3T3 L 1 cells includes antagonistic transcriptional control of a growth arrest associated gene . . ^^^ |

A novel function for Myc : inhibition of C / EBP dependent gene activation . ^^^ We find that 5 Myc dramatically down regulates the expression of myelomonocytic specific genes , such as the chicken mim 1 and lysozyme genes , both of which are known targets for C / EBP transcription factors . ^^^ We present evidence that Myc downregulates these genes by inhibiting the function of C / EBP transcription factors . ^^^ Detailed examination of the inhibitory mechanism shows that amino terminal sequences of 5 Myc , but not its DNA binding domain , are required for the suppression of C / EBP dependent transactivation . ^^^ |
