In this study , we identified Sp1 and Sp3 as major factors binding to the Sp1 sites of the p21 / WAF1 / Cip1 promoter in MG63 cells through electrophoretic mobility shift assays and showed that TSA treatment did not change their binding activities .
 GENE: Sp1; GENE: Sp3; GENE: Sp1 sites; GENE: p21; GENE: WAF1; GENE: Cip1
