    生物活性

    Scutellarin, an active flavone isolated from Scutellaria baicalensis, can down-regulates the STAT3/Girdin/Akt signaling in HCC cells, and inhibits RANKL-mediated MAPK and NF-κB signaling pathway in osteoclasts. Scutellarin is active against HIV-1IIIB, HIV-1(74V) and HIV-1KM018 with EC50s of 26 μM, 253 μM and 136 μM, respectively.

    體外研究
    (In Vitro)

    Scutellarin 處理顯著以劑量依賴性方式降低 HepG2 細(xì)胞活力,并在體外抑制 HCC 細(xì)胞的遷移和侵襲。Scutellarin 處理顯著降低 HCC 細(xì)胞中 STAT3 和 Girders of actin filaments (Girdin) 的表達(dá)及 STAT3Akt 的磷酸化。STAT3 的過(guò)表達(dá)可恢復(fù) Scutellarin 下調(diào)的 Girdin 表達(dá)、Akt 激活、遷移及侵襲。Girdin 的過(guò)表達(dá)完全抵消了 Scutellarin 對(duì) Akt 磷酸化、遷移及侵襲的抑制作用。Scutellarin 通過(guò)下調(diào) STAT3/Girdin/Akt 信號(hào)通路可在體內(nèi)抑制 HCC 細(xì)胞的轉(zhuǎn)移并在體外抑制遷移和侵襲[1]。Scutellarin 選擇性增強(qiáng) Akt 的磷酸化[2]。Scutellarin 是一種潛在的治療劑,不僅能抑制小膠質(zhì)細(xì)胞激活從而改善神經(jīng)炎癥,還能增強(qiáng)星形膠質(zhì)細(xì)胞反應(yīng)。Scutellarin 通過(guò)上調(diào)神經(jīng)營(yíng)養(yǎng)因子等增強(qiáng)星形膠質(zhì)細(xì)胞反應(yīng),顯示其神經(jīng)保護(hù)作用。顯著的是,Scutellarin 對(duì)活性星形膠質(zhì)細(xì)胞的作用由活化的小膠質(zhì)細(xì)胞介導(dǎo),支持這兩種膠質(zhì)細(xì)胞類型間的功能“交互”[3]。Scutellarin 可抑制 RANKL 介導(dǎo)的破骨細(xì)胞生成、骨吸收功能及破骨細(xì)胞特異性基因 (抗酒石酸酸性磷酸酶 (TRAP) 、組織蛋白酶 K、c-Fos、NFATc1) 的表達(dá)水平,進(jìn)一步研究表明 Scutellarin 可抑制 RANKL 介導(dǎo)的 MAPK 和 NF-κB 信號(hào)通路,包括 JNK1/2、p38、ERK1/2 和 IκBα 的磷酸化[5]。

    (In Vivo)

    Scutellarin (50 mg/kg/天) 可顯著減輕體內(nèi)肝細(xì)胞癌腫瘤的肺和肝內(nèi)轉(zhuǎn)移。Scutellarin 治療組的肺和肝內(nèi)轉(zhuǎn)移性腫瘤數(shù)量明顯少于對(duì)照組[1]。與 SAH 組相比,接受Scutellarin 治療的大鼠的神經(jīng)行為缺陷顯著減輕。與 SAH 大鼠相比,Scutellarin 增強(qiáng)了 eNOS 表達(dá)[4]。

    Cell Assay
    [1]

    HepG2 cells (1×105/well) are cultured in 96-well plates and treated in triplicate with scutellarin at concentrations of 5, 10, 20, 30, and 100 μM or vehicle alone for 24 h. The cellular viability is tested by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and is expressed as a percentage of proliferation versus controls.

    Animal Administration
    [1]

    To establish an orthotopic liver xenograft model, individual mice are anesthetized with isoflurane and a small incision is made in their abdomen. Individual mice are injected with 2×106 SK-Hep1 cells in 30 μL Matrigel into their left lobe of the liver. Twenty-four hours after orthotopic liver implantation, the mice are randomized and injected intraperitoneally with scutellarin (50 mg/kg/day) or vehicle (0.9% NaCl, normal saline) daily for 35 consecutive days (n=10 per group). Subsequently, the mice are sacrificed, and their lungs and livers are excised, fixed in 10% buffered formalin and paraffin-embedded for hematoxylin and eosin staining.

    • 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.
