The levels of OIP5-AS1 and NGFR mRNA in tumour tissues in the si-OIP5-AS1 + inhibitor-NC group were significantly lower than those in the si-NC + inhibitor-NC group, and the level of miR-186-5p was significantly higher than that in the si-NC + inhibitor-NC group. The gene discussed is NGFR; the disease is neoplasm.
