    Dihydroartemisinin (DHA) 是一種抗瘧藥。Dihydroartemisinin 處理有效上調(diào)胞質(zhì) RelA/p65 蛋白水平并下調(diào)核 RelA/p65 蛋白水平,它阻斷 RelA/p65 從胞質(zhì)溶膠的核轉(zhuǎn)運(yùn),而不是抑制 RelA/p65 蛋白合成。Dihydroartemisinin 在 RPMI 8226 細(xì)胞中誘導(dǎo)自噬。Dihydroartemisinin 抑制 RPMI 8226 細(xì)胞中的 NF-κB 活化。通過 EMSA 測定檢查 NF-κB Dihydroartemisinin 結(jié)合活性[2]。
    RPMI 8226 細(xì)胞暴露于不同濃度的 Dihydroartemisinin (10、20 和 40 μM) 12 小時,引入 TNF-α 作為 NF-κB 激活的陽性對照。與 TNF-α[1]相比,Dihydroartemisinin 以劑量依賴性方式抑制 NF-κB 活化。Dihydroartemisinin (DHA) 可增強(qiáng)光動力療法 (PDT) 對食管癌細(xì)胞的抗腫瘤作用,用 Dihydroartemisinin (80 μM)、PDT (分別為 25 和 20 J/cm2) 或其組合處理 Eca109 和 Ec9706 細(xì)胞。Dihydroartemisinin 或 PDT 單次處理分別導(dǎo)致 Eca109 細(xì)胞活力降低 37±5% 或 34±6%,Ec9706 細(xì)胞活力降低 33±7% 或 34±6%。當(dāng) PDT 與 Dihydroartemisinin 聯(lián)合使用時,細(xì)胞系的細(xì)胞活力分別降低了 59±6% 或 61±7%[2]。

    Kinase Assay
    [1]

    To determine NF-κB Dihydroartemisinin-binding activity, an electrophoretic mobility shift assay (EMSA) is performed. Nuclear extracts are prepared and incubated with 32P-end-labeled 45-mer double-stranded oligonucleotide (15 μg protein with 16 fmol DNA) from the HIV long terminal repeat, 5′-TTGTTACAAGGGACTTTCCGCTG GGGACTTTCCAGGGAGGCGTGG-3′ (boldface indicates NF-κB binding sites), for 30 min at 37 °C. The Dihydroartemisinin-protein complex formed is separated from free oligonucleotide on 6.6% native polyacrylamide gels. A double-stranded mutated oligonucleotide, 5′-TTGTTACAA CTCACTTTCCGCTGCTCACTTTCCAGGGAGGCGTGG-3′, is used to examine binding specificity of NF-κB to the DNA. The binding specificity is also examined by competition with the unlabeled oligonucleotide. Preimmune serum (PIS) is included as a negative control. The dried gels are visualized with a Storm 820, and radioactive bands are quantified using Imagequant software[1].

    Cell Assay
    [2]

    Eca109 (4×103 cells/well) and Ec9706 (5×103 cells/well) cells are grown in 96-well plates and cultured overnight to allow for cell attachment. Eca109 and Ec9706 cells are treated with Dihydroartemisinin (80 μM), PDT (25 and 20 J/cm2, respectively) or their combination. After incubation for 24h, MTT (20 μL) is added to each well and incubated for 4 h at 37°C. Formazan crystals are dissolved in 150 μL of DMSO for 10 min with shaking. The absorbance is measured at 490 nm on a plate reader, and the experiment is repeated three times[2].

    Animal Administration
    [3]

    Mice[3]
    Mice of the Kunming strain, each weighing 20-24 g, are used. In the first experiment, design to investigate the effect of multiple doses of Dihydroartemisinin on the schistosomula and adult worms of S. japonicum, mice are given three daily doses, of 200, 300, 400 or 600 mg Dihydroartemisinin/kg (in dose volumes of 25 mL/kg), on days 6-8 or 34-36 post-infection, respectively. An additional group of mice, infected but not given the drug, serve as a control.

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
