Ultrahigh-Throughput Screen (uHTS)[1]
A.基于KLF5萤光素酶细胞的筛选在测定开始之前,将每孔5µl培养基中的2500个DLD-1/pGL4.18hKLF5p细胞分配到1536孔板中。通过将20nl DMSO(最终DMSO浓度,0.4%)、单独DMSO(0%抑制对照)或LY294002(最终浓度,200µM,100%抑制对照)中的测试化合物分配到适当的孔中,立即开始测定。然后将平板在37°C下孵育27小时,并在室温下平衡30分钟。通过将5µl SteadyLite HTS萤光素酶底物分配到每个孔中,然后在室温下孵育15米来停止测定。在ViewLux平板读取器上测量孔的发光。每种化合物的抑制百分比计算如下:%抑制=[1−((Test_compound−Median_High_Control)/(Median_Low_Control−Median_High _Control。Low_Control被定义为含有DMSO的阱的发光。High_Control定义为含有LY294002的阱的发光。 B.IEC-6细胞毒性反筛选[1] 在测定开始之前,将每个孔5µl培养基中的1250个IEC-6细胞分配到1536孔板中。通过将20nL的DMSO(最终DMSO浓度,0.4%)、单独DMSO(0%抑制对照)或阿霉素(最终浓度,150µM,100%抑制对照)中的测试化合物分配到适当的孔中,立即开始测定。然后将平板在37°C下孵育48小时,并平衡至室温30分钟。通过向每个孔中分配5µl CellTiter-Glo试剂,然后在室温下孵育15分钟,停止测定。在ViewLux平板阅读器上测量阱发光。每种化合物的抑制百分比计算如下:%抑制=(1−((Test_compound-Median_High_Control)/(Median_Low_Control−Median_High_Coontrol))*100,其中:Test_compound定义为含有测试化合物的孔的发光。Low_Control被定义为含有DMSO的阱的发光。High_Control定义为含有阿霉素的孔的发光。 |

其他信息 |
The transcription factor Krüppel-like factor 5 (KLF5) is primarily expressed in the proliferative zone of the mammalian intestinal epithelium, where it regulates cell proliferation. Studies showed that inhibition of KLF5 expression reduces proliferation rates in human colorectal cancer cells and intestinal tumor formation in mice. To identify chemical probes that decrease levels of KLF5, we used cell-based ultrahigh-throughput screening (uHTS) to test compounds in the public domain of NIH, the Molecular Libraries Probe Production Centers Network library. The primary screen involved luciferase assays in the DLD-1/pGL4.18hKLF5p cell line, which stably expressed a luciferase reporter driven by the human KLF5 promoter. A cytotoxicity counterscreen was done in the rat intestinal epithelial cell line, IEC-6. We identified 97 KLF5-selective compounds with EC(50) < 10 μmol/L for KLF5 inhibition and EC(50) > 10 μmol/L for IEC-6 cytotoxicity. The two most potent compounds, CIDs (PubChem Compound IDs) 439501 and 5951923, were further characterized on the basis of computational, Western blot, and cell viability analyses. Both of these compounds, and two newly synthesized structural analogs of CID 5951923, significantly reduced endogenous KLF5 protein levels and decreased viability of several colorectal cancer cell lines without any apparent impact on IEC-6 cells. Finally, when tested in the NCI-60 panel of human cancer cell lines, compound CID 5951923 was selectively active against colon cancer cells. Our results show the feasibility of uHTS in identifying novel compounds that inhibit colorectal cancer cell proliferation by targeting KLF5.[1]

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
