Differential modulation of cyclin gene expression by MYC

P Jansen-Dürr et al. Proc Natl Acad Sci U S A. 1993.

Abstract

We have investigated the effects of deregulated expression of the human c-MYC protooncogene on cyclin gene expression and on the transcription factor E2F. We found that constitutive expression of MYC or activation of conditional MycER chimeras led to higher levels of cyclin A and cyclin E mRNA. Activation of cyclin A expression by MYC led to a growth factor-independent association of cyclin A and cdk2 with the transcription factor E2F and correlated with an increase in E2F transcriptional activity. In contrast, expression of the G1 phase cyclin D1 was strongly reduced in MYC-transformed cells. In synchronized cells, repression of cyclin D1 by MYC occurred very early in the G1 phase of the cell cycle.
