MCL-1 dependence may
drive progression of AML

CDK9 is a key regulator of
MCL-1 function
1,2,5
Disease progression and
treatment resistance in a subset
of acute myeloid leukemia (AML)
have been associated with a key
anti-apoptotic protein, myeloid
cell leukemia 1 (MCL-1). 3,6 MCL-1
is a member of the apoptosis-
regulating BCL-2 family of proteins. 7 MCL-1 mRNA transcription in
AML blasts is regulated by cyclin-
dependent kinase 9 (CDK9), 1,2 a
protein that plays a critical role in
transcription regulation without
directly affecting cell-cycle control. 5,10
In MCL-1–dependent AML,* the
AML blasts depend primarily
on the function of MCL-1 for the
anti-apoptotic mechanism of
survival. 8,9 MCL-1 inhibits apoptosis
and sustains the survival of AML
blasts, allowing them to proliferate,
which may lead to relapse. 3 MCL-1
dependence is also associated
with resistance to agents that
otherwise have activity against
leukemic blasts. 7 CDK9-mediated transcriptional

The Association for Molecular Pathology’s second
congress brings together a multidisciplinary net-
work of molecular and diagnostics professionals to
discuss its applications in health care.
regulation of anti-apoptotic
proteins, including MCL-1,
is critical for the survival of
MCL-1–dependent AML blasts. 5
Inhibition of CDK9 as a
rational therapeutic strategy
in MCL-1–dependent AML
1,5,7
Because MCL-1 has a short half-
life of 2-4 hours, the effects of
targeting its upstream regulators
are expected to reduce MCL-1
levels rapidly. 11 CDK9 inhibition
has been shown to block MCL-1
transcription, resulting in rapid
depletion of MCL-1 protein, which
may restore apoptosis in MCL-1–
dependent AML blasts. 1,5,7
Understanding the role of CDK9
in regulating MCL-1 may inform
therapeutic targeting strategies
in AML.
*The prevalence of MCL-1–dependent
AML is under investigation.
