英文摘要
Currently, it is still impossible to manipulate the timing and velocity of embryonic stem cell differentiation. This study is aiming at elucidation of molecular and cellular mechanisms of regulation for timing and velocity of stem cell differentiation. We demonstrated that activation of protein kinase A (PKA) accelerates differentiation velocity to induce approximately 2-times earlier appearance of mesoderm and other germ layer cells, reciprocally correlated with the earlier disappearan ce of pluripotent markers after ESC differentiation. PKA activation increased protein expression of G9a, a H3K9 methyltransferase, along with earlier H3K9 dimethylation and DNA methylation in Oct3/4 and Nanog gene promoters. We thus reported this novel mechanism regulating differentiation timing of embryonic stem cells(Yamamizu, Cell Stem Cell, 2012)
