For example, by directly interacting with BCL-2 and CCND1, miR-34a is reported to be associated with docetaxel resistance [8], while by targeting NOTCH 1 and PRKD1, miR-34a modulates chemosensitivity of breast cancer cells to adriamycin [9], and stimulates breast cancer stemness and drug resistance, respectively [10]. Here, NOTCH1 is linked to breast carcinoma.
