The protein made by the ASH1L gene plays a key role in the development of acute leukemia, along with other diseases. The ASH1L protein, however, has been challenging to target therapeutically. Now a team of researchers led by Jolanta Grembecka, Ph.D., and Tomasz Cierpicki, Ph.D., from the University of Michigan has developed first-in-class small molecules to inhibit ASH1L’s SET domain — preventing critical...
