Another tumor suppressor miRNA targeting DDR is miR-875-3p, which induces radiation sensitivity in PCa cells by inhibiting HR by regulating checkpoint kinase 1 (CHK1) expression and through down-regulation of Zinc Finger E-box-binding homeobox 1 (ZEB1), a protein implicated in epithelial to mesenchymal transition (EMT) [70] (Fig. 2). The gene discussed is ZEB1; the disease is neoplasm.
