Abstract

Overexpression of lysyl oxidase (LOX) is often observed in estrogen receptor negative (ER-) breast cancer patients with bone metastasis. In the present bioinformatics study, we observed that LOX is a prognostic factor for poor progression free survival in patients with ER- breast cancer. LOX overexpression was positively correlated with resistance to radiation, doxorubin and mitoxantrone, but negatively correlated with resistance to bisphosphonate, PARP1 inhibitors, cisplatin, trabectedin and gemcitabine. LOX overexpression was also associated with EMT and stemness of cancer cells, which leads to chemotherapeutic resistance and poor outcome in ER- patients. Although we suggest several therapeutic interventions that may help in the management of LOX+ ER- breast cancer patients, experiments to validate the function of LOX in ER- breast cancer are still needed.
