我们研究了Bcl-2过表达的人白血病和淋巴瘤细胞的细胞死亡机制。我们发现,依托泊苷治疗增加Beclin-1的表达,微管相关蛋白1轻链3(LC 3)的可溶性形式的自噬囊泡相关的形式LC 3-II和溶酶体/自噬体的发生在Bcl-2过表达细胞的转换。自噬抑制剂氯喹增强了依托泊苷对Bcl-2过表达淋巴瘤细胞的细胞毒性。这些数据表明,自噬可能发挥重要作用,作为保护性反应后,足叶乙甙治疗。
英文摘要
We investigated the cell death mechanism of Bcl-2 over expressing human leukemia and lymphoma cells. We found that etoposide treatment increased Beclin-1 expression, the conversion of the soluble form of microtubule-associated protein 1 light chain 3(LC3) to the autophagic vesicle-associated form LC3-II and the occurence of lysosomes/autophagosomes in Bcl-2 over expressing cells. The autophagy inhibitor chloroquine enhanced the cytotoxicity of etoposide in Bcl-2 over expressing lymphoma cells. These data indicate that autophagy may play an important role as protective response after etoposide treatment.
