Understanding cellular transcription responses to oxygen deprivation

A multiprotein complex is essential for regulating cellular responses to oxygen deprivation, a key feature of cancer, according to a Northwestern Medicine study published in the Proceedings of the National Academy of Sciences.

#BRD4-#PRC2 represses #transcription of T-helper 2-specific negative regulators during #Tcell #differentiation:
Brd4 interacts with #Polycomb repressive complex 2 (PRC2) to repress transcriptional expression of T-helper 2 (Th2)-negative regulators #Foxp3 and E3 #ubiqutin #ligase #Fbxw7 during lineage-specific differentiation of #Th2 cells from mouse primary naïve CD4+ T cells

Granted, the test case is—you guessed it—#BRD4. Nevertheless, this could be an exciting new #TPD modality if it is generalizable to other target proteins, such as those lacking accessible lysines or for which #ubiquitination is slow or inefficient.
