BJAB
BJAB是对人类疱疹病毒第四型呈阴性的人类伯基特淋巴瘤细胞系，最初是分离自一名五岁的非洲女性伯基特淋巴瘤患者[1]。然而BJAB细胞衍生而来的GC-BJAB细胞对人类疱疹病毒第四型呈阳性，并且不同于BJAB培养物在达到最大密度后很快就会凋亡，GC-BJAB培养物达到细胞饱和密度后可以长时间维持在存活状态[2]。由于已经确定了两种细胞系的同一性[3]，其生长特性的显著差异须归因于EBV基因组。
抑制
[编辑]有研究指出[4]，高浓度及长时间的白藜芦醇作用会使BJAB细胞的形态发生改变，不仅胞体变为纺锤形且两极尖细，还使细胞质变得浑浊，甚至出现核固缩或细胞核溶解的情况，干扰着BJAB细胞的细胞周期。原因是白藜芦醇能够抑制DNA复制过程所需的拮抗雌激素及BJAB细胞自分泌的活性氧[5]，从而抑制BJAB细胞的增殖。
