Oct4 and Nanog are well-known transcription factors related with self renewal of embryonic stem cell. In low-dose of Nanog, transcription of oct4 is increased; however, oct4 is down-regulated upon high-dose of Nanog. There is a negative feedback loop between oct4 and Nanog. To identify this regulation, we generated 4 nested sets for mouse oct4 promoter. Luciferase activities of oct4 were declined upon high-dose Nanog in all constructs. The declined effects of oct4 upon high-dose Nanog were moderated with DNMT and HDAC inhibitors (5-AZA-cytidine and trichostatin A) in 3 constructs (1867, 1346, 754). But, one construct (2179) was only sensitive to TSA. Taken together, these effects were also represented in semi-quantitative RT-PCR and Western blotting data. These data suggest that negative regulation of oct4 gene upon high-dose Nanog would be accomplished by DNMT and HDAC. Further, it will be studied whether these constraining molecules bind to CR1-4 region of oct4 promoter upon low- and high-dose of Nanog.
