Aims: Drug resistance is a major obstacle for a successful cancer therapy. Cell adhesion mediated drug resistance (CAM-DR) is a novel type of drug resistance and generated via interaction of cancer ce...
慢病毒载体携带的VEGFR2 shRNA对HL60的体外杀伤作用
siRNA HL60细胞 受体 血管内皮生长因子
2009/5/26
目的： 为寻找高效低毒的选择性抗白血病药物，研究慢病毒载体携带的血管内皮细胞生长因子受体2（VEGFR2）基因短发夹RNA（shRNA）对肿瘤细胞株HL60的体外杀伤作用。方法： 制备并筛选VEGFR2基因的最有效siRNA,并据此设计shRNA寡核苷酸链，构建pU6/shVEGFR2入门克隆。瞬时转染细胞，采用MTT法、RT-PCR法及Western blotting测定VEGFR2表达抑制情况...
人白血病HL60细胞的分化状态对细胞凋亡的影响
细胞分化 细胞凋亡 三尖杉酯碱 人白血病HL60细胞 c-myc基因
2010/2/25
用细胞培养和流式细胞术等方法,研究人白血病HL60细胞诱导分化后,对三尖杉酯碱(Har)和喜树碱(Cam)诱导细胞凋亡的影响。结果表明,12-豆蔻酰及13-乙酸佛波酯以16nmol·L-1浓度处理HL60细胞24h,细胞向单核/巨噬细胞方向分化,阻断于G1期;分化细胞抗Har和Cam诱导的细胞凋亡,但其c-myc基因的表达无变化。1.4%二甲基亚砜处理HL60细胞48h,细胞向粒细胞方向分化,阻断...
