4 Discontinuation of treatment with GTP/EGCG resulted in the loss of p53 acetylation at both the sites in these cells. epigallocatechin gallate tumor protein p53 Homo sapiens
5 Discontinuation of treatment with GTP/EGCG resulted in the loss of p53 acetylation at both the sites in these cells. epigallocatechin gallate tumor protein p53 Homo sapiens
6 The increased GTP/EGCG-mediated p53 acetylation enhanced its binding on the promoters of p21/waf1 and Bax, which was associated with increased accumulation of cells in the G0/G1 phase of the cell cycle and induction of apoptosis. epigallocatechin gallate tumor protein p53 Homo sapiens
