Breast cancer, a life-threatening serious disease with a high incident rate
among women, is responsible for thousands of cancer-associated death worldwide.
Numerous investigations have evaluated the possible mechanisms related to this
malignancy. Among them, non-coding RNAs (ncRNAs), i.e., microRNAs (miRNAs), long
non-coding RNAs (lncRNAs), and circular RNAs have recently attracted attention of
researchers. In addition to recent studies for evaluating the role of ncRNAs in breast
cancer etiology, some investigations have revealed that vitamin D has regulatory and
therapeutic roles in breast cancer. Moreover, an important link between vitamin D and
ncRNAs in cancer therapy has been highlighted. Herein, the aim of this study was to
discuss the available data on the mentioned link in breast cancer.
