CHFR Regulates Chemoresistance in Triple-Negative Breast Cancer through Destabilizing ZEB1

Integrated affinity purification combined with mass spectrometry and TCGA analysis identified a cell cycle-related E3 ubiquitin ligase, checkpoint with forkhead and ring finger domains (CHFR), as a key negative regulator of zinc finger E-box-binding homeobox 1 (ZEB1) in TNBC.
