Re-epithelialization of cancer cells increases autophagy and DNA damage: Implications for breast cancer dormancy and relapse

Cellular plasticity mediates tissue development as well as cancer growth and progression. In breast cancer, a shift to a more epithelial phenotype (epithelialization) underlies a state of reversible cell growth arrest called tumor dormancy, which enables drug resistance, tumor recurrence, and metastasis. Here, we explored the mechanisms driving epithelialization and dormancy in aggressive mesenchymal-like breast cancer cells in …
