    製品説明

    Selenomethionine is a naturally occurring amino acid containing selenium that has oral activity and is a common natural food source. Selenomethionine has antitumor activity[1][2][3].

    体外実験

    Selenomethionine (50 μM, 12 h) decreases the hatchability and glutathione consumption of Japanese rice embryos, but does not affect selenium accumulation[1].
    Selenomethionine (45-135 μM, 24 h) inhibits the growth of MCF-7/S breast cancer, DU-145 prostate cancer cells and UAC-375 melanoma cells in a dose-dependent manner[2].
    Selenomethionine (25-500 μM, 24 h) inhibits TBHP-induced oxidative stress and mitochondrial division by activating the Nrf2 pathway, thereby inhibiting the apoptosis of nucleus pulposus cells (NPCs) and improving intervertebral disc degeneration (IDD)[3].

    Dosage: 2mg/kg/day
    Administration: i.g
    Result: Reduced NP size, collapsed disc height, significant loss of cells, and dense ECM.
    Decreased the levels of Nrf2 and collagen II amd increased the expression level of MMP13.

    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.
