    RAW264.7 cells are harvested after induced by RANKL (50ng/mL) and tetrandrine (0, 0.125, 0.25, 0.5 ,1μM) for 5days. The proteins were used to detect osteoclastogenic proteins levels of NFATc1, CTR9, CTSK, TRAP, and MMP9. D) Tetrandrine down‐regulates osteoclastogenic gene expression of NFATc1, TRAP, CTSK, and c-fos. RAW264.7 cells are stimulated with RANKL and cultured with different concentrations of tetrandrine.

    In Vitro

    The effects of Tetrandrine (NSC-77037), a bis-benzyl-isoquinoline alkaloid, on voltage-gated Ca2+ currents (ICa) and on Ca2+-activated K+ current (IK(Ca)) and channels in isolated nerve terminals of the rat neurohypophysis are investigated using patch-clamp techniques. The non-inactivating component of ICa is inhibited by external Tetrandrine (NSC-77037) in a voltage- and dose-dependent manner, with an IC50=10.1μM. Tetrandrine (NSC-77037) decreases the channel-open probability, within bursts, with an IC50=0.21 μM[1]. To evaluate the effects of Tetrandrine on HCC cells, Huh7, HCCLM9 and Hep3B cells are treated with 0 (DMSO), 0.5, 1, 2 or 4 μM of Tetrandrine for 24 h. The cell proliferation assay indicates that Tetrandrine exhibits almost no effect on the inhibition of HCC cell proliferation at 0.5-2 μM. However, Tetrandrine (NSC-77037) inhibits HCC cell migration in a dose-dependent manner. Furthermore, a wound-healing and transwell assay shows that 2 μM Tetrandrine significantly inhibits HCC cell migration and invasion[2].

    In Vivo

    To evaluate the effect of Tetrandrine (NSC-77037) on the inhibition of tumor metastasis in vivo, HCCLM9 subcutaneous tumor xenograft models is established with athymic nude mice. When the tumor volume reach approximately 50 mm3, nude mice are orally administered vehicle or Tetrandrine (NSC-77037) (30 mg/kg) every other day for 37 days. Tetrandrine (NSC-77037) treatment inhibits tumor growth by reducing the tumor volume and weight[2].

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 0.5 mg/mL (0.80 mM); Clear solution

      This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).

    Huh7, HCCLM9 and Hep3B cells are seeded in a 96-well plate at a cell density of 5 × 103 cells/well. The cells are treated with the indicated concentrations (0-4 μM) of Tetrandrine (NSC-77037) for 24 h. The cells are subsequently stained with 20 μL of MTS for 1-2 h, and the plates are read at 490 nm on a BioTek ELx800[2].

    Animal Administration
    [2]

    Mice[2] Four-week-old male athymic BALB/c nu/nu SPF mice (body weight range from 18 g to 20 g) are used. HCCLM9 WT and HCCLM9 ATG7 KO cells (5 million) resuspended in 0.2 mL of PBS are subcutaneously implanted into the right flank of each mouse. When the tumor volume reach approximately 50 mm3, the tumor-bearing mice are randomly divided into control and treatment groups (n = 6). The control and treatment groups are administered oral injection of vehicle (0.5% methylcellulose) and Tetrandrine at 30 mg/kg of body weight every other day for 37 days. During the treatment, the tumor volumes are measured every day and are calculated.

    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.
