Manipulating transgenes using a chromosome vector.

ABSTRACT: Recent technological advances have enabled us to visualize the organization and dynamics of local chromatin structures; however, the comprehensive mechanisms by which chromatin organization modulates gene regulation are poorly understood. We designed a human artificial chromosome vector that allowed manipulation of transgenes using a method for delivering chromatin architectures into different cell lines from human to fish. This methodology enabled analysis of de novo construction, epigenetic maintenance and changes in the chromatin architecture of specific genes. Expressive and repressive architectures of human STAT3 were established from naked DNA in mouse embryonic stem cells and CHO cells, respectively. Delivery of STAT3 within repressive architecture to embryonic stem cells resulted i
