In Vitro

Tectochrysin (Techtochrysin) inhibits activity of NF-κB. Tectochrysin (Techtochrysin) binds directly to the p50 unit. Tectochrysin (Techtochrysin) concentration-dependently inhibits the translocation of p50 and p65 into the nucleus through inhibition of the phosphorylation of IκB. To assess the inhibitory effect of Tectochrysin on cell growth of colon cancer cells (SW480, HCT116), cell viability is analyzed by MTT assay. The cells are treated with varying concentrations of Tectochrysin (Techtochrysin) (1, 5, 10 μg/mL) for 24 h. Tectochrysin (Techtochrysin) inhibits cell growth in colon cancer cells in a concentration-dependent manner. Tectochrysin (Techtochrysin) inhibits SW480 cells growth with IC₅₀ value of 6.3 μg/mL and HCT116 cells growth with IC₅₀ value of 8.4 μg/mL. Morphologic observation shows that the cells are reduced in size by the treatment of NSC 80687 (10 μg/mL) in SW480 cells and HCT116 cells. However, Tectochrysin (Techtochrysin) is not cytotoxic in the normal CCD-18co cells in the tested concentration by MTT assay. To delineate whether the induction of apoptotic cell death is critical for cell growth inhibition by NSC 80687, changes are evaluated in the chromatin morphology of cells using DAPI staining. To further characterize the apoptotic cell death by Tectochrysin (Techtochrysin), TUNEL staining assays are performed, and then the labeled cells are analyzed by fluorescence microscopy. Apoptotic cells number (DAPI-positive TUNEL stained cells) in SW480 cell is increased to 1 and 58 % by 0 and 10 μg/mL NSC 80687, respectively, and 1 and 54 % by 0 and 10 μg/mL Tectochrysin in HCT116^[1].

In Vivo

To elucidate the antitumor effects of Tectochrysin in in vivo, the tumor growth in colon cancer xenograft-bearing nude mice following Tectochrysin (NSC 80687) treatments is investigated. In HCT116 xenograft studies, Tectochrysin (NSC 80687) is administrated i.p. twice per week for 3 weeks to mice with tumors ranging from 200 to 300 mm³ in volume. The mice are weighed twice per week. The changes in body weights between the control and the Tectochrysin (NSC 80687)-treated mice (n=10) are not remarkably different during the experiment. However, On day 21, the final tumor weights are recorded. Tumor weights and volumes in mice treated with Tectochrysin (NSC 80687) at 5 mg/kg doses are 57.9 % and 46.4 % of the vehicle group, respectively^[1].

Stock Solution Working Solution

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 90% Corn Oil

Solubility: ≥ 1 mg/mL (3.73 mM); Clear solution

This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol

Cell Assay^[1]

Each SW480, HCT116, HT-29, A549 and MCF-7 cell line (1×10⁴ cells) is incubated in 200 μL of RPMI 1640, DMEM medium with NSC 80687 (concentrations ranging from 1, 5, 10 μg/mL) in a 96-well flat-bottomed plate in triplicate. After incubation for 72 h at 37°C, MTT diluted in RPMI 1640, DMEM medium are added to each well and incubation is carried out for 90 min. The supernatant is then discarded and the crystal products are eluted with DMSO (200 μL/well). Colorimetric evaluation is performed with a spectrophotometer at 540 nm. The apoptosis assay is first performed by using DAPI staining. SW480 and HCT116 human colon cancer cells are cultured with concentrations of NSC 80687 (5 μg/mL), and induction of apoptotic cell death is evaluated after 24 h. Tunel assay is done^[1].

Animal Administration^[1]

Mice^[1]
Five-week-old male BALB/c athymic nude mice (n=10/group) are used. HCT116 cancer cells are injected subcutaneously (1×10⁷ cells/0.1 mL PBS/animal) into the lower right flanks of mice. After 14 days, when the tumors have reached an average volume of 200-300 mm³, the tumor-bearing nude mice are intraperitoneally injected with Tectochrysin (NSC 80687) (5 mg/kg dissolved in 0.1 % DMSO) twice per week for 3 weeks. The tumor volumes are measured with vernier calipers and calculated^[1].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
