Therefore, to evaluate the mechanism of TPA responsiveness of the SNE motifs and of a related 16-bp SEE ( SRF/ ETS element ) motif found in the HCMV and chimpanzee CMV MIE enhancers , we have examined the functional responses and protein binding properties of multimerized wild-type and mutant elements added upstream to the SCMV MIE or simian virus 40 minimal promoter regions in the U-937 , K-562 , HL-60 , THP-1 , and Jurkat cell lines .
 SEE, SNE motifs, THP-1, Jurkat cell lines, SCMV MIE, HL-60, SRF/ ETS element, simian virus 40 minimal promoter regions, U-937, SNE, MIE, K-562, ETS
