ABSTRACT
Objective To determine the Golgi dispersal in radiation damaged cells and the protective effect of vanillin derivatives.Methods Immunofluorescence, cell cycle analysis of flow-cytometry,Western blot,and clone formation were used.Results Immunofluorescence observation showed that the Golgi dispersal caused by 2 Gy 60 Coγ-ray was significantly increased in a dose-dependent manner in the range of 4-10 Gy as was demonstrated by the fact that the Golgi area was significantly increased. When the irradiated cells were treated with the radioprotective agent VND3207, a vanillin derivative,the Golgi dispersal induced by radiation was significantly reduced.The radiation-induced Golgi dispersal was also displayed in a pattern of time-course after irradiation in the HeLa cells, and persisted at least to 36 h post-irradiation. Cell cycle test results indicated that the Golgi dispersal was not associated with the G2/M arrest triggered by radiation-induced DNA damage response.VND3207 could promote cell survival by plate colony formation assay.Conclusion The Golgi dispersal can be caused byγ-ray irradiation in a dose-and time-dependent manner, and VND3207 can provide a good protection against radiation injury associated with inhibited Golgi dispersal.
