Journal-Based CME: The PML Hub: An Emerging Actor of Leukemia Therapies

This Journal-Based CME activity consists of a full-text article that is free to read, a multiple-choice question test, and an evaluation/self-assessment. Learners are tested on their comprehension of the key concepts, with the objective of enriching their clinical practice and patient care through better understanding of scientific advances and new techniques in the fields covered by Journal of Experimental Medicine (JEM).

Questions for this complimentary, online-only activity have been designed by JEM editors in collaboration with the article authors. Each CME activity should take approximately 1 hour to complete.

The article selected for this activity is The PML hub: An emerging actor of leukemia therapies by Domitille Rérolle and Hugues de Thé of the Center for Interdisciplinary Research in Biology, Collège de France, Inserm, PSL Research University in Paris, France.

Article Abstract

Promyelocytic leukemia (PML) assembles into nuclear domains that have attracted considerable attention from cell and cancer biologists. Upon stress, PML nuclear bodies modulate sumoylation and other post-translational modifications, providing an integrated molecular framework for the multiple roles of PML in apoptosis, senescence, or metabolism. PML is both a sensor and an effector of oxidative stress. Emerging data has demonstrated its key role in promoting therapy response in several hematological malignancies. While these membrane-less nuclear hubs can enforce efficient cancer cell clearance, their downstream pathways deserve better characterization. PML nuclear bodies are druggable and their known modulators may have broader clinical utilities than initially thought.

About Journal of Experimental Medicine (JEM) and CME Activities

JEM publishes peer-reviewed papers within the field of medical biology, providing novel conceptual insights into immunology, cancer biology, neuroscience, inflammation, vascular biology, microbial pathogenesis, and stem cell biology. These studies range from original findings on all aspects of disease pathogenesis to novel therapeutic approaches. Articles designated for Journal-Based CME have been selected by JEM editors for their clinical relevance and ability to address practice-based gaps.
