Background |
It is a selective estrogen receptor modulator. It is also a potent Hsp90 activator that enhances the activity of the Hsp90 chaperone ATPase. Can activate autophagy and induce apoptosis. |
Biological Activity |
Tamoxifen是一种选择性雌激素受体调节剂 (SERM),可阻断乳腺细胞中的雌激素作用,并可激活其他细胞,如骨骼,肝脏和子宫细胞中的雌激素活性。[1-4] |
In Vitro |
他莫昔芬显示出对MCF-7细胞的强烈抑制作用(EC50 =1.41μM)和较小程度的T47D细胞(EC50 =2.5μM),但不影响MDA-MB-231细胞[2]。 |
In Vivo |
他莫昔芬诱导型基因敲除策略具有明显的优点,即基因的表达可以在组织特异性方式中随意消除在成年小鼠中。为了研究Med1在成年心脏中的作用,给予7周龄TmcsMed1 - / - 小鼠每天腹膜内注射剂量为65mg/kg的他莫昔芬5天,然后在选定的时间间隔内杀死。 RNA的qPCR分析显示,在注射他莫昔芬3天后,Med1表达开始下降(约70%减少),并且注射5天后,心脏中的Med1表达几乎不可检测。成年小鼠中他莫昔芬诱导的心脏特异性Med1(TmcsMed1 - / -)破坏引起扩张性心肌病[3]。 |
Animal Experiment |
小鼠[3]然后给予7周龄的TmcsMed1 - / - 小鼠和野生型同窝小鼠,以65mg/kg体重的日剂量腹膜内给予他莫昔芬5天,然后在开始他莫昔芬治疗后以选定的间隔杀死。对于每个实验,使用3至5只小鼠作为对照和csMed1 - / - 。为了获得存活曲线,使用41 csMed1 - / - 和41 csMed1fl/fl小鼠。使用他莫昔芬诱导模型,将13只TmcsMed - / - 小鼠和相同数量的同窝仔畜用于存活曲线实验。动物安乐死的具体标准包括缺乏食物或水摄入,缓慢或无活动,心跳加弱或缺乏,胸部无心悸以及无呼吸运动。通过腹膜内戊巴比妥注射以150mg/kg体重的剂量对小鼠实施安乐死,以使痛苦最小化。 |
