miR-128-3p increases the effect of TMZ in vivo. (A) RT-PCR to verify miR-128-3p gene expression, U6 as an internal reference gene; (B) Photographs of the dissected tumors. (C) tumor growth curve analysis; (D) tumor weight statistical analysis; (E) U251 brain invasion test, (1) Stereotactic injection of mixed U251 cells (LV-miR-NC group (DIL-red) + LV-miR-128-3p group (DIO-green)) (2) intracerebral injection sites; (3) and (5) same sagittal plane fluorescence imaging, (4) and (6) same cross-sectional fluorescence imaging, The red circle represents the intracerebral invasion range of the LV-miR-NC group, and the green circle represents the intracerebral invasion range of the LV-miR-128-3p group, (7) and (8) Sagittal and cross-sectional merge imaging; (F) statistical analysis of intracerebral invasion experiments, each sample was repeated three times. Data are expressed as mean ± standard error. Compared with the TMZ + LV-miR-NC group, * means P < 0.05, ** means P < 0.01, and *** means P < 0.001.
