    生物活性

    Luteolin (Luteoline), a flavanoid compound, is a potent Nrf2 inhibitor. Luteolin has anti-inflammatory, anti-cancer properties, including the induction of apoptosis and cell cycle arrest, and the inhibition of metastasis and angiogenesis, in several cancer cell lines, including human non-small lung cancer cells[1][2][3].

    体外研究
    (In Vitro)

    Luteolin (0-160 µM; 24 hours; NCI-H460 cells) treatment inhibits the viability of NCI-H460 cells in a concentration-dependent manner[1].
    Luteolin (20-80 µM; 24 hours; NCI-H460 cells) treatment causes an accumulation of cells in the S phase[1].
    Luteolin (320-580 µM; 48 hours; NCI-H460 cells) treatment induces apoptosis[1].
    Luteolin (20-80 µM; 24 hours; NCI-H460 cells) treatment increases the protein expression levels of apoptotic regulatory proteins, including the Bax/Bcl-2 ratio, in a concentration-dependent manner, however, only 80 µM Luteolin inhibits the expression of Bad. Luteolin also decreases the expression of Sirt1 in the NCI-H460 cell line in a concentration-dependent manner[1].

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

    Cell Cycle Analysis[1]

    Cell Line: NCI-H460 cells
    Concentration: 20 µM, 40 µM, 80 µM
    Incubation Time: 24 hours
    Result: Induced cell cycle arrest in the S phase.

    Apoptosis Analysis[1]

    Incubation Time: 48 hours
    Result: Apoptotic fraction was markedly increased.

    Western Blot Analysis[1]

    Cell Line: NCI-H460 cells
    Concentration: 20 µM, 40 µM, 80 µM
    Incubation Time: 24 hours
    Result: Increased the protein expression levels of apoptotic regulatory proteins and decreased the expression of Sirt1 in the NCI-H460 cell line in a concentration-dependent manner.
    体内研究
    (In Vivo)

    Luteolin (10-100 mg/kg; oral gavage; daily; for 12 weeks; adult male Wistar rats) has an antioxidant effect and can also protect against non-alcoholic steatohepatitis through targeting the pro-inflammatory IL-1 and Il-18 pathways in rats with a high carbohydrate/high fat diet[2].

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

    Animal Model: Adult male Wistar rats (200-220 g)[2]
    Dosage: 10 mg/kg, 25 mg/kg, 50 mg/kg or 100 mg/kg
    Administration: Oral gavage; daily; for 12 weeks
    Result: Significantly reduced ALT and AST activity and reduced levels of bilirubin, hyaluronic acid and malondialdehyde. Shows an antioxidant activity such as a significant increase in reduced glutathione. IFN-γ, TNF-α, IL-1α and IL-18 levels decreased significantly.

    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.
