Let‐7/miR‐98 regulate Fas/Fas‐mediated apoptosis 29; miR‐98 regulates expression of tumour suppressor gene FUS1 30; miR‐98 could inhibit tumour angiogenesis and invasion by targeting activin receptor‐like kinase‐4/matrix metalloproteinase‐11 31; let‐7/miR‐98 might be involved in regulating progesterone receptor membrane component 1 expression in ovarian cancer cells 32. The gene discussed is FAS; the disease is ovarian cancer.
