| 方法 | Proliferation assay. Cell proliferation assays were performed for a number of cell lines as described earlier with some modifications. For these assays, cells were plated at densities that allowed untreated cells to grow logarithmically during the course of a 3-d assay. Briefly, cells were plated in 96- or 384-well plates in culture medium containing 10% fetal bovine serum and incubated overnight at 37° C in 5% CO2. Cells were then treated with GSK690693 (ranging from 30 μmol/L-1.5 nmol/L) and incubated for 72 h. Cell proliferation was measured using the CellTiter Glo (Promega) reagent according to the manufacturer's protocol. Data were analyzed using the XLFit (IDBS Ltd.) curve-fitting tool for Microsoft Excel. IC50 values were obtained by fitting data to Eq. 2. |

建议您制定动物给药及实验方案时,尽量参考已发表的相关实验文献(溶剂种类及配比众多,简单地溶解目的化合物,并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题,未必能保证目的化合物在动物体内充分发挥生物学效用)。
体内实验的工作液,建议您现用现配,当天使用;如在配制过程中出现沉淀、析出现象,可以通过超声和(或)加热的方式助溶。
切勿一次性将产品全部溶解。
请在下面的计算器中,输入您的动物实验相关数据并点击计算,即可得到该实验的总需药量和工作液终浓度。
例如您给药剂量是10 mg/kg,平均每只动物的体重为20 g,每只动物的给药体积是100 μL,动物数量为20只,则该动物实验的总需药量为4 mg,工作液终浓度为2 mg/mL。
1:鉴于实验过程的损耗,建议您至少多配1-2只动物的量;
2:为该产品最终给药时的浓度。

GSK690693(AbMole,M1789)是一种ATP竞争性的泛Akt(pan-Akt)激酶抑制剂,通过特异性阻断Akt信号轴发挥调控作用。GSK690693在胰腺癌来源异种移植(PDX)小鼠模型中,可使肿瘤体积减少至盐水对照组的61%,并通过干扰Akt通路实现衰老-凋亡信号的转换,显著改善耐药性[1]。GSK690693在结肠癌的研究中,与Irinotecan (CPT-11)联用可降低EVI1高表达细胞系的存活率,抑制肿瘤进展[2],相关实验采用2D/3D细胞模型(如HCT116等结肠癌细胞系)和异种移植小鼠模型[2]。在神经系统研究中,GSK690693(CAS No.:937174-76-0)表现出多重活性:在创伤后应激障碍(PTSD)小鼠模型(C57BL/6品系)中,GSK690693能阻断跑步机运动对海马神经发生和行为改善的促进作用[3]。而在大鼠原代神经元培养体系中,GSK690693能完全消除CXCL12诱导的胆碱能基因(CHT1、VAChT、ChAT)表达上调,并逆转胆碱乙酰转移酶活性和乙酰胆碱产量的增加[4]。GSK690693在骨癌痛模型(BCP,SD大鼠)中,通过抑制脊髓组织Akt蛋白磷酸化,降低WNK1表达,从而发挥缓解作用[5]。GSK690693(AbMole,M1789)在细胞凋亡调控中表现出多机制特性。首先在横纹肌肉瘤(RMS)细胞中,GSK690693与组蛋白去乙酰化酶抑制剂JNJ-26481585(Quisinostat)协同增强caspase-9/-3的活化,该效应可被BCL-2或MCL-1过表达所拮抗[6]。GSK690693在卵巢癌细胞系OVCAR3中,联合miR-1284过表达可下调p-Akt和Bcl-2,同时上调Bax和caspase-3表达[7]。此外,在骨肉瘤143B细胞系及小鼠异种移植模型中,GSK690693通过抑制ZIP10-ITGA10-PI3K/AKT轴逆转化疗耐药性[8]。在干细胞分化调控方面,GSK690693可阻断STC2诱导的室管膜下区神经前体细胞(NSPCs,来源于小鼠)的神经元分化,而Akt激活剂SC79能逆转此效应[9]。
