UP FRONT Calendar 2019 American Society of Clinical Oncology Annual Meeting European Hematology Association Annual Congress May 31 – June 4, 2019 Chicago, IL The American Society of Clinical Oncology brings together 32,000 oncology professionals from around the world to discuss state-of-the-art treatment modalities, new therapies, and ongoing controversies in the field. Athens, Greece Highlights of ASH® in the Mediterranean March 15 – 16, 2019 Athens, Greece Highlights of ASH® in Latin America April 5 – 6, 2019 Lima, Peru June 13 – 16, 2019 Amsterdam, The Netherlands The 24th Annual Congress covers every subspecialty in hematology, with experts from around the world sharing original data and discussing the latest evidence-based approaches to treating hematologic disorders. 2019 American Association for Cancer Research Annual Meeting March 29 – April 3, 2019 Atlanta, GA The annual meeting will explore the topics of integrative cancer science, global impact, and individualized patient care by bringing together researchers and clinicians from international institutions. Oncology Nursing Society Annual Congress April 11 – 14, 2019 Anaheim, CA The 44th Annual Congress features the latest in research, clinical practice, advanced practice, and leadership, presented by oncology nursing professionals. 2nd AMP Global 2019 Congress on Molecular Pathology 1-5 AML BLAST SURVIVAL CDK9 MCL-1 mRNA MCL-1 dependence may drive progression of AML 3,6 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 May 16 – 18, 2019 Hong Kong, China 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. A matter of cell life and cell death 4th International Symposium on Immunotherapy May 24 – 25, 2019 London, UK The Institute for Cancer Vaccines and Immunother- apy’s symposium will feature discussions about the impact of immunotherapies like checkpoint inhibitors and chimeric antigen receptor T-cell therapies in a variety of tumor types. June 18 – 22, 2019 Lugano, Switzerland At the 15th International Conference on Malignant Lymphoma, the scientific community involved in the study and treatment of lymphoid neoplasms present the latest basic and translational science in the field. CDK9 regulation of MCL-1 inhibits apoptosis, enabling National Comprehensive Cancer Network 24th Annual Conference March 21 – 23, 2019 Orlando, FL With the theme of “Improving the Quality, Effectiveness, and Efficiency of Cancer Care,” the annual conference brings together oncology professionals to discuss the data upon which the NCCN Guidelines® are based.
