Table III. The mice reconstituted with MLL–CBP (bromo + HAT) develop a preleukemic disease similar to that observed with full length MLL–CBP.

aThe number of mice reconstituted with each construct is shown in parentheses.
bThe mice were bled at 7 weeks (experiment 1) or 11 weeks (experiment 2) post-reconstitution. The values shown are the mean ± SEM.
cThree mice died of acute myeloid leukemia between 139 and 174 days after transplantation. Unfortunately, this cohort could not be studied further as the remaining mice succumbed to hyperthermia following an air conditioner failure.
