Klf4 cooperates with Oct3/4 and Sox2 to activate the Lefty1 core promoter in embryonic stem cells

ABSTRACT: To characterize Klf4 downstream genes, we performed microarray analyses of the ES cells knocked down by siRNA of Klf4 gene. Keywords: individual genetic characteristic design ES cells grow without feeders on gelatin coated in complete ES medium. Cells were incubated at 37 0C; 5% CO2. ES cells were transfected with siRNA and pCAGEGFP-IP plasmid. After transfection, cells were cultured for 24 hours, following to drag selection for more 24 hours in the presence of puromycin to ensure concentration of transfectants. Total RNA were extracted with Trizol reagent (Sigma) according to the manufacturer’s instructions.

Although the POU transcription factor Oct3/4 is pivotal in maintaining self renewal of embryonic stem (ES) cells, little is known of its molecular mechanisms. We previously reported that the N-terminal transactivation domain of Oct3/4 is required for activation of Lefty1 expression (H. Niwa, S. Masui, I. Chambers, A. G. Smith, and J. Miyazaki, Mol. Cell. Biol. 22:1526-1536, 2002). Here we test whether Lefty1 is a direct target of Oct3/4. We identified an ES cell-specific enhancer upstream of the  ...[more]
