Customer Review

    Actinomycin D purchased from MCE. Usage Cited in: Cancer Lett. 2017 Aug 18;407:45-56.

    UM-SCC6 and UM-SCC6H cells are treated with Actinomycin D (ActD 5 μg/mL) for the indicated times. The IGF2 mRNA level is measured by RT-PCR.

    Actinomycin D purchased from MCE. Usage Cited in: Cell Res. 2018 Oct 4.

    Melanoma A375 cells are treated with SSZ (Sulfasalazine, 125 μM) with or without FeSO4 (100 μM) for 6 h to detect the ROS level or 24 h to assess the pyroptotic features (including morphology, GSDME cleavage, and LDH release), unless specifically defined.

    Description

    Actinomycin D inhibits DNA repair with an IC50 of 0.42 μM.

    IC50 & Target

    IC50: 0.42 μM (DNA repair)[1]

    In Vitro

    Actinomycin D is an inhibitor of DNA transcription and replication[1]. Actinomycin D markedly reduces the vascular smooth muscle cells (SMC) proliferation via the inhibition of BrdU incorporation at 80 nM. This is further supported by the G1-phase arrest using a flowcytometric analysis. Actinomycin D is extremely potent with an inhibitory concentration IC50 at 0.4 nM, whereas the lethal dose LD50 is at 260 microM. The protein expression levels of proliferating cell nuclear antigen (PCNA), focal adhesion kinase (FAK), and Raf are all suppressed by Actinomycin D. Extracellular signal-regulated kinases (Erk) involved in cell-cycle arrest are found to increase by Actinomycin D[2].

    In Vivo

    The pluronic gel containing 80 nM and 80μM Actinomycin D is applied topically to surround the rat carotid adventitia, the thickness of neointima is substantially reduced (45 and 55%, respectively)[2]. Mice in the Actinomycin D and fludarabine group lives significantly longer than the control group with P values of <0.001 and 0.007, respectively. Interestingly, single treatment with Actinomycin D is superior to fludarabine regarding overall survival (P=0.026)[3].

    [1]

    Actinomycin D is co-incubated for 3 h at 30°C with a reaction mixture containing: 120 mg of a whole-cell extract of HeLa cells, 70 mM KCl, 0.4 mM each of dGTP, dCTP, dATP, and digoxygenylated-dUTP in reaction buffer containing 40mM Hepes-KOH (pH 7.6), 5 mM MgCl2, 0.5 mM Dithiotreitol, 2 mM EGTA, 10 mM phosphocreatine, 50 mg/mL creatine phosphate, and 360 mg/mL of bovine serum albumin. During this reaction, DNA damage is recognized and the excised patches are replaced by neosynthesized DNA fragments. Throughout this DNA synthesis, digoxygenylated-dUMPs are incorporated. The DNA repair reaction is stopped by three washes[1].

    Animal Administration
    [3]

    Mice[3]
    The original Eμ-TCL1a transgenic mice have been backcrossed to C57BL/6 mice for >9 generations.The C57BL/6 wild-type mice are engrafted with tumor cells from Eμ-TCL-1 transgenic mice. The percentage of CD5+/CD19+ cells in the peripheral blood is routinely checked in mice by taking blood from the tail vein and analyzing it via flow cytometry. When the percentage of tumor cells in the peripheral blood reached 40-60%, treatment is started. Actinomycin D (0.06 mg/kg by 10 days) is applied daily via i.p. injections.
