Hypoxia-induced phase separation of ZHX2 alters chromatin looping to drive cancer metastasis
Gao et al. reveal a type of hypoxia-specific phase separation mediated by ZHX2 IDR, which serves as a scaffold for recruiting CTCF and active transcriptional regulators (e.g., RNA Pol II-S5P, MED1, and BRD4), thus reprogramming chromatin looping to drive oncogene transcription and cancer metastasis.
