In DLBCL cells, EI1 (KB-145943) inhibits cellular H3K27 methylation and activates Ezh2 target gene p16 expression. In mouse embryonic fibroblasts, EI1 (KB-145943) also inhibit H3K27me3 and cell proliferation. In addition, EI1 (KB-145943) selectively inhibits the growth of DLBCL cells carrying Ezh2 mutation, and causes cell cycle arrest and apoptosis[1].

プロトコル
Exponentially growing diffused large B-cell lymphoma (DLBCL) cells are seeded in 12-well plates at a density of 1×105 cells/mL with the indicated concentration of EI1 (KB-145943). Viable cell number is determined every 3-4 d for up to 14 or 15 d by Vi-CELL. Mouse embryonic fibroblasts (MEFs) are seeded in a six-well plate at 2.5×104 cell/mL and treated with EI1 (KB-145943) (3.3 μM) or 4-OH-tamoxifen (100 nM). Viable cell number is determined at days 3, 6 and 11. On days of cell counts, fresh growth medium and compound are replenwashed and cells split back to a density of 1×105 cells/mL. Total cell number is expressed as split-adjusted viable cells per milliliter. IC50 is calculated by PRISM and all proliferation experiments are repeated more than two times and representative data are presented.
