4、s. Niclosamide (1 M) inhibits the EGF-induced nuclear translocation of STAT3 in Du145cells. Niclosamide ( 1. Niclosamide can block SARS-CoV replication at a micromolar concentration in VeroE6 cells infected with SARS-CoV 2. Niclosamide ( 3. Niclosamide inhibits the TNF-induced NF-B reporteractivity

5、in a dose- and time-dependent manner in U2OS cells. Niclosamide (125 nM) inhibits NF-B activationinduced by p65, IKK, IKK, IKK, and TAK1 in U2OS cells. Niclosamide ( 4.体内研究 Niclosamide (40 mg/kg/d, i.p.) suppresses the growth of xenografted AML cells in nude mice bearing HL-60 xenograft tumors 4.PRO

6、TOCOLKinase Assay 1 All of the protein kinases are expressed either in Sf9 insect cells or in E.coli as recombinant GST-fusionproteins or His-tagged proteins. A radiometric protein kinase assay is used for measuring the kinase activityof the 22 protein kinases. Briefly, for each protein kinase, 50 L

7、 reaction cocktail containing 60 mM HEPES-NaOH, 3 mM MgCl2, 3 mM MnCl2, 3 M Na-orthovanadate, 1.2 mM DTT, 50 g/mL PEG20000, 1 M -33P-ATP, Niclosamide, adequate amount of enzyme and its substrate. The PKC-alpha assay additionallycontain 1 mM Ca2, 4 mM EDTA, 5 g/mL phosphatidylserine and 1 g/mL 1, 2-D

8、ioleyl-glycerol. The reactioncocktails are incubated at 37C for 60 minutes and stop with 50 L 2% (v/v) H3PO4. Incorporation of 33Pi isdetermined with a microplate scintillation counter. The activities and the IC50 values are calculated usingQuattro Workflow V2.28.MCE has not independently confirmed

9、the accuracy of these methods. They are for reference only.Cell Assay 1 Cells are plated in 96-well culture plates with cell density of 3-4 103 cells/well and treat with Niclosamide byadding 100 L medium containing Niclosamide of various concentrations on the second day. After 72-hourstreatment, MTT

10、 is added to each well and incubated for additional 4-5 hours, and the absorbance ismeasured on a microplate reader at 570 nm. Cell growth inhibition is evaluated as the ratio of theabsorbance of the sample to that of the control. The results are representative of at least 3 independentexperiments.M

11、CE has not independently confirmed the accuracy of these methods. They are for reference only.Animal Male nu/nu BALB/c mice are used in the assay. HL-60 cells are inoculated s.c. on the flanks of 4- to 6-wk-oldAdministration 4 mice. Tumors are measured every other day with use of calipers. Mice bear

12、ing HL-60 xenografts arerandomized to receive treatment with normal saline (control) or p-niclosamide for 15 days (n=7 animalseach). Tumor volumes are calculated by the following formula: a2b0.4, where a is the smallest diameterand b is the diameter perpendicular to a. After mice are euthanized, xen

13、ografts are dissected, weighed, orpreserved.MCE has not independently confirmed the accuracy of these methods. They are for reference only.户使本产品发表的科研献 Cell Syst. 2018 Apr 25;6(4):424-443.e7.
