Deregulated c-myc expression in quiescent CHO cells induces target gene transcription and subsequent apoptotic phenotype.

Abstract excerpt

Human c-myc cDNA was fused with the hormone-binding domain (HBD) cDNA of murine estrogen receptor gene and the chimeric gene was introduced into the CHO cells. The fusion protein, c-MycER, becomes activated when the synthetic steroid, 4-hydroxy-tamoxifen (OHT), binds HBD. Activated c-MycER, likely c-Myc, can induce quiescent CHO cells reentry into S phase and subsequent cell death under serum-free condition. In...
