Research Abstract

We have previously shown that TIP60 histone acetyltransferase complex regulates histone H2AX eviction upon DNA damage, which facilitate DNA damage response signaling. In this study, we tested whether chromatin dynamics via H2AX regulated by TIP60 is involved in the establishment or maintenance of pluripotency of stem cells including iPS cells. As a result, we found that TIP60 is not involved in the establishment of pluripotency of iPS cells.
