Abstract:

目的:探讨CYP1B1敲除在小鼠骨髓移植中生存情况中的作用。方法:20只10周龄雄性C57BL/6J小鼠用8.25Gy 60 Co全身照射后,随机分为两组(KO组和WT组),于3h内分别尾静脉注射WT小鼠骨髓和CYP1B1敲除(CYP1B1-/-)小鼠骨髓,观察两组小鼠存活情况以及移植物抗宿主病(GVHD)的情况。结果:8.25Gy60 Co照射后,CYP1B1-/-→WT(KO)组小鼠骨髓移植后平均生存时间长于WT→WT(WT)组小鼠骨髓移植平均生存时间,GVHD评分始终低于WT组,小鼠体重增长率始终高于WT组小鼠,辐射后小鼠体重增量显著高于WT组小鼠,P<0.05。结论:CYP1B1敲除在小鼠骨髓移植中有延长平均生存时间、增加小鼠体重、改善GVHD的效果,对骨髓移植后的小鼠恢复有一定保护作用
