An up-regulated circ_0007841 was discovered in ovarian cancer, and circ_0007841 enhanced cancer cell metastasis and growth in vitro and in nude mice by up-regulating Mex-3 RNA Binding Family Member C expression through competitively adsorbing miR-151-3p, indicating an oncogenic role of circ_0007841 in ovarian cancer [10]. The gene discussed is MEX3C; the disease is ovarian cancer.
