Genome-wide studies identify the role of PML/RARa phase separation in PML/RARa-driven transcriptional dysregulation.
Acute promyelocytic leukemia (APL) is characterized by a specific t(15;17) chromosome translocation that generates the promyelocytic leukemia/retinoic acid receptor-a (PML/RARa) fusion gene. However, the mechanism underlying PML/RARa mediated transcriptional dysregulation remain unclear. Here, we performed the transcription profiling in NB4, an APL patient-derived cell line. Overall design: Expression profiling of NB4 cells with endogenous PML/RARa knock-down and replaced with empty vector or full-length PML/RARa or phase separation-imcompetent mutants (F158E or ?IDR) using RNA-seq.
