    LW6 影響 HIF-1α 蛋白的穩(wěn)定性。LW6 促進野生型 HIF-1α 的降解,但不促進氧依賴性降解域羥基化位點處 P402A 和 P564A 修飾的 DM-HIF-1α 的降解。LW6 誘導 von Hippel-Lindau (VHL) 蛋白的表達,VHL 蛋白與脯氨酰羥基化的 HIF-1α 相互作用,進行蛋白酶體降解。在 LW6 存在的情況下,VHL 的敲低不會消除 HIF-1α 蛋白的積累,這表明 LW6 通過調(diào)節(jié) VHL 表達來降解 HIF-1α[2]
    在過表達 BCRP 的 MDCKII-BCRP 細胞中,LW6 顯著增強了 BCRP 底物米托蒽醌的細胞積累。 LW6 濃度為 0.1-10 μM 時也會下調(diào) BCRP 表達[3]。
    LW6 濃度為 20 μM 時,可抑制 A549 細胞中缺氧誘導的 HIF 1α 表達,且不依賴于 von Hippel Lindau 蛋白。LW6 可誘導缺氧選擇性細胞凋亡,同時降低線粒體膜電位[4]

    Cell Assay
    [2]

    Inhibition of HIF-1a is assayed by a reporter assay using dualluciferase reporter assay system. HCT116 cells in 75-90% confluence are transiently co-transfected with pGL3-HRE-luciferase plasmid containing six copies of HREs from human VEGF genes and pRLSV40 encoding firefly renilla luciferase and incubated for 24 h. Cells are treated with LW6 or 17-AAG for 16 h before report assay. Luciferase activity is integrated over a 10 second period and measured using a luminometer[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [2]

    Mice: The mice receive the following treatments using a dosing vehicle solution, containing 10% dimethylacetamide, 10% Cremophor EL and 80% of sodium carbonate buffer (pH 10), by intraperitoneal (i.p.) injection: group1(control group; six mice), vehicle solution; group2 (six mice), LW6 at a dose of 10 and 20mg/kg (QD); and group 3 (six mice), topotecan at a dose of 2mg/kg, (Q2D), which is the dose and dosing schedule that showed more than 60% inhibition of growth of HCT116 tumors. The treatments are continued for 13 days[2].

    Help & FAQs
    • 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.
