In order to verify whether ZFAS1 exerts a cancer-promoting effect through miR-100-3p, we tested that overexpression of miR-100-3p can reduce the viability and migration ability of NPC cells, and this phenomenon was reversed after overexpression of ZFAS1 (Fig. 5I, J, all p < 0.05). The gene discussed is ZFAS1; the disease is cancer.
