For example, miR‐215 and miR‐363 targeted NOB1 and inhibited the growth and invasion of epithelial ovarian cancer cells, miR‐326 functioned as a tumour suppressor in glioma by targeting NOB1, and miR 744 suppressed the proliferation and invasion of papillary thyroid cancer cells by directly targeting NOB1. The gene discussed is NOB1; the disease is ovarian carcinoma.
