Abstract
The transcription factor TWIST1 is a basic helix-loop-helix protein that regulates epithelial-mesenchymal transition (EMT) in early embryonic morphogenesis, cancer development, and cancer metastasis. The regulation of TWIST1 remains poorly understood. Recently, we found that autophagy deficiency stabilizes TWIST1 protein through SQSTM1/p62 accumulation. SQSTM1 binds with TWIST1 to inhibit TWIST1 degradation in both autophagosomes and proteasomes. SQSTM1-mediated TWIST1 stabilization promotes EMT in vitro, and tumor growth and metastasis in mice. We propose autophagy as a new mechanism to control the TWIST1 protein levels and activity in cancer development and progression.Entities:
