Hypoxia-induced CTCF mediates alternative splicing via coupling chromatin looping and RNA Pol II pause to promote EMT in breast cancer
Published 2025-02-01“…Summary: Hypoxia influences the epithelial-mesenchymal transition (EMT) through the remodeling of the chromatin structure, epigenetics, and alternative splicing. Hypoxia drives CCCTC-binding factor (CTCF) induction through hypoxia-inducible factor 1-alpha (HIF1α), which promotes EMT, although the underlying mechanisms remain unclear. …”
