苜蓿银纹夜蛾核型多角体病毒的感染对Sf9细胞周期的影响

Affection of Infection of Autographa californica nucleopolyhe-drovirus on Sf9 Cell Cycle

病毒的感染导致细胞内部发生一系列变化。应用流式细胞仪FACS的荧光检测 ,测出Sf9细胞完成整个周期循环大约需要 18h ,G1、S、G2 /M各时相的时间间隔约为 6h ;AcNPV感染Sf9细胞 12 18h ,细胞被抑制于G2 /M期 ;Sf9细胞同步于G1/S期后释放细胞并用AcNPV感染 ,12h后 ,2 / 3的细胞处于G2 /M期 ,1/

Baculovirus infection resulted in many changes in host cells.The progress of the cell cycle of Spodoptera frgiperda IPLB-Sf21-AE clonal isolate 9 (Sf9) cells was directed by Flow cytometry analysis(FACS).The results showed that the whole time of the cell cycle was about 18 hours and the gapes between every two phases were about 6 hours.At 12-18 hours post AcNPV infection,Sf9 cells were arrested in G\-2/M phase.When the cells in G\-1/S phase synchronized by druge were infected by AcNPV,2/3 of the cells was in G\-2/M phase and 1/3 of the cells in S phase.
