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.

Lower grade gliomas (LGGs) have highly diverse clinical phenotypes. The histological grade and type are insufficient to accurately predict the clinical outcomes of patients with LGGs. Therefore, identification of biomarkers that can facilitate the prediction of clinical outcomes in LGGs is urgently needed. Gene expression of LOX has been identified as a biomarker for various cancers. However, the clinical significance of LOX expression in LGGs has not been investigated. In this study, we analyzed the glioma RNA-seq dataset from TCGA (The Cancer Genome atlas) and identified lysyl oxidase (LOX) as a potential biomarker for LGGs. Kaplan-Meier survival analysis revealed that high LOX expression is associated with worse overall survival and recurrence free survival in LGG patients. Besides, high LOX expression is associated with poor response to primary therapy, follow-up treatment, targeted molecular therapy, and radiation therapy. Univariate and multivariate Cox regression analyses further confirmed LOX expression as an independent prognostic factor for LGG patients. Finally, we observed that LOX expression is significantly correlated with EMT (epithelial to mesenchymal transition) and IDH1 status in LGGs. In conclusion, our analyses suggest that LOX expression is a potential biomarker for prognosis and therapeutic response in LGGs.
