  ABSTRACT: The P19CL6 mouse embryonic carcinoma cells efficiently differentiate into cardiac muscle cells in the presence of DMSO. A reporter plasmid for cardiac muscle differentiation was constructed by connecting the CMV enhancer and a 250 bp MLC-2v promoter in front of the GFP gene to further evaluate the role of the CMV enhancer. This plasmid (pCBVenh/MLC-2vpro/EGFP) was stably introduced into P19CL6 cells, and the transfectant differentiated into cardiomyocytes with DMSO. Upon DMSO addition, GFP was immediately transcribed (within 2 days) and the amount of the transcript increased with cultivation. Concomitantly, GFP fluorescence was detected in the cells under a microscope. However, native MLC-2v was transcribed later on day 4. This expression time course is different from that of GFP. Clearly the CMV enhancer responded immediately to DMSO. Since GATA DNA-binding proteins play crucial roles in the initiation of cardiomyocyte differentiation, such a response could be ascribed to the presence of multiple GATA motifs in the enhancer sequence but not in the native MLC-2v promoter. Thus the CMV enhancer may be not only useful for gene therapy and monitoring cell differentiation but also the study of the role of GATA transcription factors expressed in P19CL6 cells.
