The protective effect of minocycline (4 μM) on radiation-induced apoptosis in primary neurons assayed by TUNEL analysis. (a) Bright field images of cultured primary neurons, 60× . (b) Field images of DAPI (blue) and TUNEL (green) staining of cultured primary neurons from different groups. (c) Quantitative analysis of radiation-induced neural apoptosis in different groups at 24 and 48 h post irradiation. **P < 0.01 and ***P < 0.001 compared with the relative control.
