Research Abstract |
In this project, we performed microRNA profiling for future application to breast cancer diagnosis and therapy. First, we identified miR-26a/30b as microRNAs involved in molecular mechanisms of trastuzumab therapy for HER2-positive breast cancer. Mir-26a/30b inhibited cell growth of breast cancer cells by targeting CCNE2. Secondary, we demonstrated that epigenetical regulation of miR200b cluster is associated with epithelial-mesenchymal transition of breast cancer cells. The miR200b cluster members inhibit cell motility by targeting fibronectin.
