Overview of Gene Research
Pml, short for promyelocytic leukemia protein, is a key organizer of PML nuclear bodies (NBs), membrane-less organelles in the nucleus. It belongs to the tripartite motif (TRIM) family. PML NBs play a crucial role in cellular homeostasis, influencing multiple signaling pathways such as those related to senescence, apoptosis, cell cycle, and DNA damage responses [1,2,3,5]. Dysregulation of Pml is associated with diseases, especially cancer [1].
One of the key findings is in acute promyelocytic leukemia (APL), where the oncoprotein PML/RARα inhibits PML NBs assembly, leading to leukemogenesis [3]. Also, murine PML-null primary cells are resistant to TGF-β-induced apoptosis, indicating Pml's role in this process [4]. Pml isoforms generated by alternative splicing have distinct functions; for example, cytoplasmic Pml activates TGF-β signaling, while nuclear Pml is involved in TGF-β-induced caspase 8 activation and apoptosis [4].
In conclusion, Pml is essential for maintaining cellular homeostasis through its role in PML NBs. Its dysregulation is closely related to cancer, especially APL. Studies on Pml-null mouse models have revealed its role in TGF-β-induced apoptosis, highlighting its importance in understanding disease mechanisms and potentially developing targeted therapies [3,4].
