蒽贝素(Embelin)是一种X连锁凋亡抑制蛋白(X-linked inhibitor of apoptosis protein,XIAP)的小分子抑制剂,可以抑制XIAP的生成和活性,从而解除XIAP的抗凋亡作用,使凋亡顺利进行.研究了Embelin抑制肝癌细胞Bel-7404增殖的机制.采用不同...蒽贝素(Embelin)是一种X连锁凋亡抑制蛋白(X-linked inhibitor of apoptosis protein,XIAP)的小分子抑制剂,可以抑制XIAP的生成和活性,从而解除XIAP的抗凋亡作用,使凋亡顺利进行.研究了Embelin抑制肝癌细胞Bel-7404增殖的机制.采用不同浓度梯度,通过荧光显微镜、Hochest33342染色、MTT检测、AnnexinⅤ/PI流式细胞术和Western blot分别检测Embelin对Bel-7404细胞的形态学变化、凋亡小体形成、细胞存活率、细胞凋亡水平、凋亡信号转导相关蛋白表达的影响.结果显示,Embelin能明显抑制Bel-7404细胞增殖,并通过激活caspase通路以及阻断NF-κB信号通路诱导Bel-7404细胞凋亡,为进一步利用Embelin进行肝癌治疗的研究打下一定的基础.展开更多
腺病毒是目前肿瘤基因治疗研究的常用载体,而5型腺病毒(Ad5)以其复制效率高、载体容量大等优势而被广泛用于基因治疗的相关研究。比较5型腺病毒对人白血病细胞K562及其耐药株K562/ADR的感染效率,并分析引起这种差异的分子机制。流式细...腺病毒是目前肿瘤基因治疗研究的常用载体,而5型腺病毒(Ad5)以其复制效率高、载体容量大等优势而被广泛用于基因治疗的相关研究。比较5型腺病毒对人白血病细胞K562及其耐药株K562/ADR的感染效率,并分析引起这种差异的分子机制。流式细胞术及荧光显微镜观察,结果显示,5型腺病毒对K562/ADR的感染效率明显高于K562;Real time PCR定量分析表明K562/ADR细胞株表面的CAR表达水平约为K562的1.33倍(P<0.05),而整合素αν表达则是K562的4.36倍(P<0.01)。展开更多
