Expression Profile of Transcription Factor ELK-1 and ELK-1 Target Genes on Lymphoma-Leukemia Cell Lines
Öz
Prognostic molecular markers identified in leukemia are becoming increasingly important especially in risk stratification and to determine therapy. In this study, we investigate the role of ELK-1 transcription factor and its potential target genes in four cell lines; Daudi, Jurkat, K-562 and HL-60. To evaluate ELK-1, MCPIP, MCL-1, BCL-10, CEBPB and SRF genes expression profiles we have performed a Real-time PCR analysis on Daudi, Jurkat, K-562 and HL-60 cell lines. ELK-1 over expression concomitant with SRF overexpression was detected only in Daudi cell line while only SRF overexpression was detected in jurkat cells. Expression of MCPIP, MCL-1, BCL-10 and CEBPB genes were decreased in all cell lines. Protein levels or phosphorylation status of ELK-1, BCL-10, CEBPB, MCL-1, MCPIP and SRF, moreover, changes that may occur when ELK-1 continuous overexpression is provided or completely silenced in these cell lines have not been evaluated. These questions are suggestions for future investigations.
