Fig. 9. Trichostatin A suppresses the effects of AML1-ETO in zebrafish
embryos. (A-C) DMSO or 0.5 µM TSA was added to
Tg(hsp:AML1-ETO) embryos 2 hours before (A,B) or at the end of a
1-hour heat treatment (C) at 38°C at 18 hpf. Tg(hsp:AML1-ETO)
embryos that had not been subjected to the heat treatment were used as a
control. TSA treatment rescues scl and gata1 downregulation
and blocks the accumulation of Mpo+ cells caused by
AML1-ETO expression.
