New research, 'Simultaneous activation of p53 and inhibition of XIAP enhance the activation of apoptosis signaling pathways in AML,' is the subject of a report. "Activation of p53 by murine double minute (MDM2) antagonist nutlin-3a or inhibition of X-linked inhibitor of apoptosis (XIAP) induces apoptosis in acute myeloid leukemia (AML) cells. We demonstrate that concomitant inhibition of MDM2 by nutlin-3a and of XIAP by small molecule antagonists synergistically induced apoptosis in p53 wild-type OCI-AML3 and Molm13 cells," investigators in the United States report.

"Knockdown of p53 by shRNA blunted the synergy, and down-regulation of XIAP by antisense oligonucleotide...
