    In Vitro

    CA-074Me (5 μM and 50 μM) inhibits RANKL-induced osteoclastogenesis in BMM cells derived from C57BL/6J and NOD/ShiLtJ mice. CA-074Me exerts its anti-osteoclastogenic effect within 24 hours post-RANKL stimulation in vitro. CA-074Me does not exert its anti-osteoclastogenic effect via the MAPK-ERK signaling cascade. CA-074Me inhibits c-FOS upregulation and subsequent NFATc1 autoamplification following RANKL stimulation.[2].
    CA-074Me reduces apoptosis induced by CVB1[3].

    In Vivo

    Hippocampal CA1 neuronal programmed necrosis induced by global cerebral I/R injury is prevented by CA074-me (1 μg, 10 μg) both pre-treatment and post-treatment. The rupture of lysosomal membrane and the leakage of cathepsin-B, and this is strongly inhibited by CA074-me pre-treatment. The overexpression and nuclear translocation of RIP3 and the reduction of NAD+ level after I/R injury are also inhibited, while the upregulation of Hsp70 is strengthened by CA074-me pre-treatment[1].
    CA-074Me (30 mg/kg) is capable of inhibiting osteoclastogenesis and bone degradation in vivo[2].
    In the CVB+CA-074Me (4 mg/kg/day i.m.) guinea pigs group, the scores of inflammation significantly decrease in comparison with the CVB+None group. In CVB+CA-074Me group, the number of CD8+T cells decrease in comparison with the sham group[3].

    In Vivo:

    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: ≥ 2.5 mg/mL (6.29 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 2.5 mg/mL (6.29 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    Kinase Assay
    [2]

    After seven days of cell culture and osteoclast generation, the media is removed and washed three times with PBS. BMMs are fixed with a fixing solution supplied by the manufacturer. The cells are incubated at 37°C with a solution containing deionized water, Fast Garnet GBC, Napthol phosphate, Acetate, and Tartrate for 1 h. The staining solution is removed, washed with PBS (3×), and air-dried. TRAP positive cells with three or more nuclei across whole culture area are counted as multinucleated osteoclasts using light microscopy.

    Animal Administration
    [2]

    RANKL (0.08 mg/kg) with and without CA-074Me (10 mg/kg or 30 mg/kg) are mixed in sterile, nonimmunogenic 1% Extracel-HP gel. The gel is composed of thiol-modified sodium hyaluronate, thiol-modified heparin, thiol-modified gelatin, and degassed deionized sterile water. The hydrogel mixture is prepared in an aseptic hood using a sterile syringe. The control sham hydrogel contained sterile Phosphate Buffered Saline (PBS) without any cytokines. The osteolysis group is given 0.08 mg/kg RANKL in a hydrogel to induce pathologic bone loss. The hydrogel-only, hydrogel-RANKL, and hydrogel-RANKL-CA-074Me mixture is injected into 8-week old male mice calvarium in an aseptic hood (n = 5) following general anesthesia (80 mg/kg of ketamine and 7 mg/kg of xylazine). After four days, the calvaria are excised, fixed in 4% formaldehyde for 24 h, decalcified in 20% EDTA for one week, and sectioned into slides from paraffin blocks. The slides undergo Tartrate-Resistant Acid Phosphatase (TRAP) staining to identify osteoclasts.

    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.
