Compared with those in normal control cells, the immunofluorescence signals of EGR1 and HOXB9 were obviously lower in glioma cells overexpressing miR‐192 (EGR1: 7.40 ± 0.79 vs. 28.35 ± 1.56; HOXB9: 10.75 ± 1.19 vs. 30.37 ± 2.28; *p < 0.05; Figure 3E,F). The gene discussed is EGR1; the disease is central nervous system cancer.
