HOXB9 and central nervous system cancer: Cloning experiments revealed that, compared with those in the normal control group, the number of newborn glioma cells overexpressing miR‐192 was obviously lower (100.3 ± 14.57 vs. 445.7 ± 14.19; *p < 0.05), whereas simultaneous high expression of EGR1 or HOXB9 partially abrogated these changes (242.3 ± 17.01, 240.7 ± 14.57 vs. 100.3 ± 14.57; *p < 0.05).
